Types and uses of fiberglass "gossamer." Instructions for using fiberglass - smooth walls and ceiling Let's start gluing

The use of fiberglass web allows you to make the interior finishing both more durable and smooth. A different kinds fiberglass, each of which has its own characteristics, makes it easy to choose the appropriate option for any conditions - from the ceiling of an apartment to the walls of an industrial building.

By using fiberglass web, you can increase the strength of the surface of ceilings and walls, reducing the likelihood of cracks without the use of expensive technologies and saving time. These features make the “spider web” one of the most popular finishing materials. Although for different conditions It is advisable to use your own type of fiberglass and a suitable adhesive for it.

What is a "web"

Painting fiberglass is an environmentally friendly and lightweight material created on the basis of fiberglass and organic resin. It is a non-woven fabric, very tear-resistant and does not have a clear pattern. The surface of the canvas consists of fibers, which, unlike glass wallpaper, do not intertwine and are arranged in a chaotic manner. And the material got its name due to its soft and pleasant to the touch texture.

Depending on the thickness, the “web” is divided into classes. On the market you can find options with densities from 25 to 65 g/m2. m. The higher this indicator, the stronger the surface finished with fiberglass will be. However, for ceilings, on the contrary, it is recommended to choose a lighter option that adheres better to a horizontal surface.

Types and parameters

Three main types are used in construction - with a density of 25, 40 and 50 g/m2. The first option, 1 m2 of which weighs only 25 grams, is optimal when painting ceilings, since the lower weight increases the convenience of gluing. Because of this, the material is often called “ceiling cobweb”. In addition, fiberglass with a low density absorbs less paint. However, it can only be used if there are no large surface irregularities or cracks.

“Gossamer” with a density of 40 g/m2 is considered universal, since it is almost twice as strong as lightweight material and cheaper than thicker options. This option is chosen for subsequent painting of surfaces that are more likely to be damaged than the ceiling. It is permissible to use fiberglass for ceilings finished with dilapidated plaster, and in rooms with high vibration loads.

One of the most durable types of “gossamer” - material with a density of 50 g/m2 - allows you to close large cracks. Withstanding a large mechanical load, it may become the only option for finishing the premises of a production workshop, workshop or garage, where the likelihood of damage to the enclosing structures is much higher. The cost of its installation increases - both due to the price of the “gossamer” and due to the fact that the higher density also increases the consumption of glue for fiberglass web. Due to the significant costs, this option is practically not used in residential buildings and apartments.

Benefits of fiberglass

To purchase quality material, it is advisable to choose products from well-known brands - such as the Finnish company Wellton, the Dutch brand Spektrum and the Swedish manufacturers Samtex and Oscar. It is worth paying attention to domestic production– for example, on fiberglass webbing X Glass, produced in different regions Russia. Depending on the brand and density, their price can vary significantly - from $100 to $250 and more per roll of 50 m2.

Materials such as Oscar fiberglass fiberglass, which is wear-resistant and affordable price. It can only be cut or torn on purpose using sharp objects. Fiberglass of this brand requires a minimum of paint - even if the painting work is carried out without putty. And, unlike products from lesser-known brands, you can paint it more than once.

Wellton painting fiberglass canvas is also in demand when carrying out repair and construction work, the advantages of which include:

• increased fire safety due to the non-flammability of the material;
• resistance to high temperatures, humidity and aggressive environments;
• hypoallergenic;
• long service life;
• high density.

Regardless of the brand of “spider web”, among its advantages there are the following characteristics:

• environmental friendliness, which is expressed in the ability of fiberglass-lined walls to “breathe”, allowing water vapor to pass through and maintaining an optimal level of humidity;
• absence of static on the surface;
• easy cleaning - even painted fiberglass is easier to clean compared to other finishing materials.

A minor disadvantage of using a “web” is the danger of getting hurt by small particles of material when cutting it. For this reason, it is best to work with fiberglass while wearing personal protection– hand gloves, respirators, goggles, rubberized and thick clothing.

Application of material

The most popular application for painting fiberglass is for walls that are already plastered and finished with plasterboard. In this case, the material quite effectively replaces the finishing putty, preventing the appearance of new flaws and cracks, and hiding the old ones. At the same time, the use of fiberglass web allows you to additionally reinforce the base - a wall or ceiling - if it is impossible to use drywall (for example, for fear of reducing the height of an already small room due to plasterboard sheets and profiles holding them). You can also buy fiberglass instead of embossed wallpaper - installing the “web” will require less time and money.

In the absence of serious requirements for the quality of the surface, the “cobweb” does not even need to be puttied. It is enough to use special glue for fiberglass and paint it. Although this costs 2–3 times more paint.

Thanks to the use of fiberglass for painting, walls and ceilings are protected from cracks as a result of:

• building shrinkage;
• thermal expansion of enclosing structures;
• constant exposure to vibrations from nearby equipment, construction equipment or railways.

Fiberglass, which is glued only with special glue for webs, can also be used as an intermediate layer for polymer and vulcanized roofing materials. To ensure adhesion, the coating is protected with a cloth on one side. You can also find fiberglass in the composition waterproofing materials, wall and floor panels, and even pipelines, for which the “web” serves as additional protection.

Features of the “cobweb” sticker

There are several nuances that allow you to both correctly glue fiberglass and do it with minimal consumption of materials. First of all, before carrying out work, you must make sure that certain conditions are met - temperature within 15-25°C and humidity not higher than 60%. During the gluing process, the fiberglass should not be in a draft or exposed to direct sunlight. Approximately the same requirements are indicated in the instructions for Bostik fiberglass adhesive, which is one of the best options when performing work.

The process of gluing the “cobweb” begins with preparing the surface, which must be cleaned of dust and completely puttied, except for the smallest cracks. At the same stage, you choose which glue for fiberglass will be used. First of all, you should abandon the usual solutions and mixtures used to glue wallpaper - starch-based substances do not hold such a canvas well. More suitable option may be the use of Bostik glue for fiberglass, which contains PVA with a strength several times higher than that of a starch base.

It is not recommended to choose plaster as a base - due to its high density, it will not be able to be saturated with glue and will not hold the canvas firmly enough. Liquid putty is also not suitable, and after trying to stick a “web” on it, bubbles may appear in places that are not sufficiently saturated with the adhesive. All this can only be avoided by using glue for fiberglass - ready-made or in the form of a mixture.

It is advisable to use different adhesives for each type of “cobweb”:

• fiberglass adhesive Oscar will become the best option for sticking material of the same brand with a density of 40 g/m2. m;
• for Wellton brand fiberglass, a similar adhesive is best suited;
• At the same time, Cleo glue for fiberglass, which is also used for non-woven wallpaper, is compatible with any brand of canvas.

You can achieve optimal consumption of the mixture by calculating that 10 grams is enough for 1 square meter. m fiberglass. And one 300-gram pack is enough for a 25-meter roll. The preparation time for the solution, if it is not purchased ready-made, but dry, does not exceed 10–15 minutes. And setting occurs within 12–48 hours, depending on the brand of glue and fiberglass - you can check the specific value on the packaging with the mixture.

The method of gluing fiberglass consists of several stages:

1. Treatment of walls or ceilings with deep impregnation.
2. Applying pre-prepared glue. Using this method of gluing fiberglass to the ceiling or walls, it is important not to miss a single unimpregnated area. At the same time, you should not leave excess adhesive, which is removed with a spatula.
3. Gluing the first sheet, starting from the corner, and smoothing the edges of the material to improve the reinforcing properties.
4. Applying the next portion of glue to the already glued part (the canvases are glued overlapping).
5. Laying the next piece of fiberglass.
6. Cutting the canvases using a stationery knife precisely at the joint and removing the cut parts.
7. Repeat the same steps until the surface is finished.

Regardless of whether the walls or ceilings will be wallpapered or painted, after the fiberglass has completely dried, they are treated with finishing putty. And the already puttied surface is cleaned using an abrasive mesh (N150 or N120). It is not recommended to skip this stage, since gluing fiberglass for painting without additional leveling will only result in a large waste of paint.

After completion of the work, the remains of Oscar glue for fiberglass or other mixture, as well as the “cobwebs” remaining after the work, should be disposed of along with the rest of the construction waste.

Not everyone knows what paintable fiberglass is: this innovative finishing material appeared on the market relatively recently and is actively gaining popularity due to its valuable properties. Like other types of modern materials, painting fiberglass web provides previously unavailable advantages in the process of finishing work.

Area of ​​application of the material

What it is? Fiberglass is a non-woven fabric obtained by pressing and consisting of the smallest glass fibers. This is a thin translucent material, therefore, in professional jargon, painting fiberglass is often called gossamer.

Why do you need painting fiberglass? It guarantees the avoidance of visible damage to walls and ceilings. The appearance of cracks on surfaces covered with plaster and putty is not always associated with the unprofessionalism of the workers who carried out the repairs. Cracking is due to physical properties traditional building materials that shrink over time when exposed to dry air.

Another reason for the appearance of cracks is constant vibration, which is typical for houses located next to a highway or railroad. Due to the appearance of cracks, previously it was necessary to frequently renew the decorative coating.

The use of fiberglass allows you to obtain perfectly smooth, durable and crack-resistant walls and ceilings.

Hypoallergenic, Fire safety, ease of use, durability and the ability to transmit water vapor, thanks to which the decorated surfaces have optimal humidity, determine the increasingly frequent use of cobwebs for reinforcing walls and ceilings.

Specifications

Painting fiberglass is a lightweight fibrous material obtained from natural raw materials, which is quartz sand.

Fiberglass web is supplied in rolls, the length of the canvas is 50 m, width 1 m.

The density of fiberglass varies from 25 to 50 g/m2.

It is better to choose fiberglass of higher density for walls, and lower density for ceilings.

The material can be used at temperatures from - 40 to + 60 ° C, which makes it suitable for any climatic conditions.

The web is breathable and hygienic: it does not electrify, does not accumulate dust, can withstand wet cleaning, and does not form mold or mildew. The material does not release into the air harmful substances and does not support combustion. All this coupled with resistance to mechanical damage and the possibility of quick application gives the web an advantage over other types of finishing materials.

Precautionary measures

Fiberglass web forms a hard, wear-resistant coating on the wall that can be washed, but it acquires these qualities only in combination with glue. Before we talk about putting it on the walls, you should take precautions.

The material that has not yet been glued is quite fragile, and its small particles can get into the respiratory tract. Once on the skin and mucous membranes, glass fibers cause irritation, so when working, be sure to use a respirator, safety glasses and protective clothing.

You can glue cobwebs only at a certain temperature (from + 15 to + 25 ° C) and air humidity of no more than 60%. During work, drafts are not allowed; direct sunlight must be avoided.

How to glue glass fiber correctly? It is necessary that the walls are pre-leveled and puttied. Before gluing, you need to carefully putty and reinforce the seams between the slabs and then ensure that they do not coincide with the boundaries of the glass panels. Fiberglass can be glued to putty only after applying a primer deep penetration, which will avoid excess consumption of adhesive.

The technology assumes that the web can be glued only with special compounds that do not contain starch, for example, Bostik, Oscar, Wellton adhesives produced by fiberglass manufacturers. The same compositions

It should be taken into account that the material has a reverse side and a smoother front side: it is important not to confuse it.

Rules for gluing

The material should be glued as follows:

• cut the material into strips according to the height of the walls with an allowance of up to 10 cm;
• according to the instructions, prepare a solution from a dry substance - the preparation time should not exceed 15 minutes (a ready-made solution is also sold, but it is much more expensive);
• Apply glue evenly without gaps to the wall or ceiling - you need to cover with glue an area slightly larger than the width of the first canvas;
• strictly vertically, pressing with a roller or a flexible plastic spatula, glue the first canvas - pasting begins from the corner closest to the window, the canvas is positioned end-to-end;
• apply the next portion of glue and attach the second canvas overlapping - for the paint to look even, the pile on the canvases should be directed in one direction;
• use a stationery knife to cut off the excess under the ceiling, above the floor and exactly along the joint (to make it smooth, it is convenient to press a wide spatula to the borders and cut along its edge);
• Cover the glued canvases with glue on top - you need to stop when the color becomes uniform.

The video will show you how to glue fiberglass sheets to the ceiling.

It is important that the room remains closed until the glue has completely dried. A draft can completely destroy the results of the work, causing the paintings to peel off.

How to prepare fiberglass for painting

Craftsmen are often interested in questions: is it necessary to prime fiberglass, and is it necessary to putty fiberglass and why is this done? There is no need to prime the coating before or painting, because the walls have already been primed before gluing it on. In addition, the glue acts as a primer.

The question of whether puttying is necessary does not have a clear answer. Fiberglass has a beautiful texture, which is sometimes preferable to preserve, but the paint consumption will be very high and at least 4-5 layers will be required. Paint will make the joints noticeable: even if they are made perfectly, their mere presence will not at all decorate the room. It is better to putty fiberglass before painting for another reason: small fibers can get into the air, which is harmful to health, and putty completely prevents their penetration.

What to putty on? There is no special putty for fiberglass; you can use any finishing mixture on gypsum or polymer based, the main thing is that it is of good quality.

How to putty painting fiberglass? The technology has some features:

• by the time the putty is applied, the glue must be completely dry;
• if the coating was pasted several days ago, it needs to be cleaned of dust;
• the adjacent surface is protected with masking tape;
• putty is applied in two layers with an interval of 24 hours;
• the thickness of the first layer should not exceed 2 mm;
• the second layer should be just as thin and completely cover the first;
• After drying, the putty is sanded using a block with sandpaper grain size no more than P150.

Fiberglass putty allows you to get a perfectly flat, durable surface.

Painting fiberglass

How to paint fiberglass? If you decide to paint fiberglass without prior puttying, you will not need to prime it, but its texture will be visible even under many layers of paint. Still, painted walls or ceilings will have a more attractive appearance if they have been previously puttied; in this case, you need to apply a primer. To paint walls, it is better to choose paints based on water based, which fit well and are easy to use.

Fiberglass is painted using the same technology as other materials.

The paint is applied with a roller until there are no areas of uneven tone left on the painted surface.

Is it possible on fiberglass? Yes, because this material is not a finishing material. Fiberglass for wallpaper is a common finishing option, but before final finishing surfaces need to be puttied and primed.

Fiberglass is rarely used as a decorative covering, but it is irreplaceable as a reinforcing material. Its use will allow you to achieve a perfectly smooth surface, and cosmetic repairs will not be required for much longer.

You can spend a lot of effort and money on finishing materials for your apartment, but in the end, due to incorrect technology, the result will quickly become unusable. It is especially difficult to produce, since new buildings shrink and cracks are inevitable in the first years. In this article we will talk about fiberglass: its application, characteristics, prices, and most importantly - how to stick it on yourself.

Beginners may confuse painting fiberglass “gossamer” with glass wallpaper, but in fact these are different things, only in appearance they are very similar. Fiberglass also consists of fiberglass strands, but it is produced by pressing rather than on a loom. Sheets of fiberglass are thin and translucent. The surface is smooth, but due to their structure they are prickly.

This material has all the qualities of glass wallpaper, that is:

• resistant to fire, water, chemical and mechanical influences;
• does not cause allergies;
• consists of environmentally friendly material;
• does not accumulate static electricity;
• allows air to pass through, so the walls “breathe”.

However, despite the listed characteristics, the web has vulnerabilities. If a crack has formed parallel to or next to a seam, it will come out. This often happens when fiberglass is glued to drywall. Therefore, you need to avoid gluing the fabric along the seams of the plasterboard and retreat at least a few centimeters.

Painting fiberglass is sold in rolls of 20 and 50 meters, 1 m wide. Its price depends on the density of the material (20-65 g/sq. m.), the cost varies between 380-800 rubles per 50 sq. m. m. The most optimal web is with a dense structure, 45-55 g/sq. m.

Areas of use

Fiberglass "gossamer" is used to reinforce the base before finishing, but not as finishing coating. It is used for plasterboard structures, walls, ceilings. You can call him the most effective means in the fight against cracks.

The video will show the technology and features of using fiberglass for interior decoration:

Glue selection

Glue for fiberglass is used specially for glass wallpaper. Sometimes it comes included right away. Be sure to follow the proportions indicated on the package when diluting the glue; it should not be liquid. Glue must be taken with a large reserve, since the consumption of fiberglass is much higher than for simple wallpaper.

Like any wallpaper, painting fiberglass is very susceptible to drafts when drying. Therefore, under no circumstances open the windows during operation. According to SNiP 3.04.01-87. “Insulating and finishing coatings”, during wallpapering, the wallpaper must be protected from drafts, direct sunlight and constant humidity must be established in the room. The same rules apply when working with many floor coverings.

Preparatory work

The walls are prepared in the same way as for wallpapering, but small cracks do not need to be sealed. If the width of the crack allows you to get into it with a spatula, you need to pre-treat it with a strong putty (for example, Knauf Uniflot), and then sand the surface. The surface must be smooth, puttied and treated with an appropriate primer.

Let's start gluing

Now let's figure out how to glue fiberglass to walls or ceilings. To do this, apply glue liberally to the surface. At first, it will be enough for the width of one sheet. The glue will quickly absorb into the canvas, so you almost won’t have to remove it from there.

• • The canvas can be cut to any length, whatever is more convenient for you. For walls you can cut off the full height, and for the ceiling no more than 2 m.

When gluing, it is important to trace the position of the front part of the canvas. Usually it is directed inside the roll. Both sides look almost identical, so check the label for this information.

• • Place the first piece of paper on the surface and smooth it gradually with your hands so that the edge coincides with the corner of the room. Then go over it with a plastic wallpaper spatula to remove excess air and air bubbles from the inside. This should be done in a herringbone motion, from the middle to the edges.

• • When the sheet is firmly seated, cut off the excess and soak the top of the sheet again with glue so that it is thoroughly saturated. Then go over the surface again with a spatula, rubbing the glue inside. The sheet should be completely saturated and darken slightly from moisture.

• • Then cut off the next sheet. You need to glue it with an overlap; on the ceiling it is better to place the canvas along the room.
  • Apply glue to the surface overlapping the old sheet. In the same way we glue it, soak it and press it. To get an even and invisible seam at the junction of two sheets, take a sharp knife and cut a line through two layers of fiberglass. Additionally, the seam is impregnated with glue. The same technique applies to adjacent sheets. It’s okay if the seam turns out uneven: the main thing is that it is smooth and invisible after finishing. The canvas needs to be cut at the corners.

When working, it is necessary to observe safety precautions: use gloves, a respirator, a hat, and long sleeves tucked in. Sharp fiberglass particles can enter the respiratory tract and skin and cause irritation.

• After a day, the glue will dry, and you can begin further finishing. To make fiberglass for painting, you need to putty it in at least two layers. This will hide its texture and reduce paint consumption. One layer of putty is enough for wallpaper.

What to do if a crack appears?

If a crack does appear, it can be easily fixed. A fiber patch is glued directly on top of the putty so that its width is at least 6 cm larger than the crack.

Then take a knife, apply good pressure and make a cut around the perimeter: through the patch, a layer of putty and the old canvas. Remove the layer of putty and glue the resulting patch to the exact size. Apply several layers of putty on top.
If you want to extend the life of your trim, be sure to use one of these inexpensive but very useful material like fiberglass. It is especially relevant for repairing cracks in plasterboard ceilings and boxes that often burst at the seams. If you follow the technology for installing the structure and add to this the correct reinforcement of the joints, you will forever forget about microcracks.

Nowadays industry produces very a wide range of various materials for construction and finishing works, which greatly facilitate the task of the craftsmen, and the resulting result is much better. Such materials include painting fiberglass canvas, which got its name due to its external similarity to a real spider web.

This type of fiberglass appeared on the construction market not so long ago, but is already in great demand among craftsmen who have already used it in their work at least once. The use of such material allows for high-quality finishing, quickly getting rid of existing problems with the surfaces of walls and ceilings, and also preventing the emergence of new ones.

What is painting fiberglass

How is fiberglass made?

Many homeowners at all stages of work prefer to choose exclusively environmentally friendly materials for finishing their houses and apartments, which do not emit toxic substances during their operation and at the same time are not subject to rapid aging or wear. It is to this group of building materials that any type of fiberglass can be safely included. Due to its absolute harmlessness, its canvases can be used in all rooms without exception, including children's rooms, bedrooms and kitchens.

The fiberglass from which the canvas is formed is made from a glass melt that goes through an extrusion process, that is, pressing it through special spinning dies with holes different diameters. The result is fibers of varying thicknesses.

Fiberglass "gossamer" is made from very thin fibers. They are so thin that they become visible to the naked eye only after they are combined into canvases.

Unlike the fiberglass from which they are made, “gossamer” is a non-woven material and does not have a clear, regular pattern, since its threads are randomly located. The process of making fiberglass is somewhat reminiscent of paper production. The finest glass fibers enter the conveyor, where they are distributed on the surface of the belt, and then undergo a pressing process under high pressure with a certain temperature conditions. A thin, even sheet with a smooth surface emerges from the press. It is immediately wound into large reels, and from them it is distributed into small rolls, packaged and sent to a warehouse or store.

The density of the finished pressed fiberglass “web” can vary in the range from 25 to 50 g/m².

Advantages and disadvantages of fiberglass "gossamer"

This auxiliary finishing material has its advantages and disadvantages, and it must be admitted that there are many more of the former. It’s worth talking about them first.

So, dignity:

• Fiberglass sheets do not accumulate static electricity.
• The material is waterproof and completely unaffected by wet environments.
• Resistant to mechanical stress.
• Completely inert to any chemical reagents used in the field of construction and finishing
• The canvas is air and vapor permeable, so mold does not appear on the surface and under the fiberglass canvas.
• Fiberglass is absolutely not subject to corrosion.
• The material is hypoallergenic - harmless for people suffering from hypersensitivity to allergens or respiratory diseases.
• Fiberglass is completely non-flammable, has a certain fire resistance, and is resistant to sudden changes temperatures
• Thanks to its structure, it perfectly reinforces and levels surfaces.
• Calmly withstands several dyeing cycles.
• It is durable, as it is not subject to either chemical or biological decomposition.
• Does not attract or absorb dirt, odors and dust.
• What is very important is that the price of fiberglass “gossamer” belongs to the category of publicly available.

Fiberglass also has a few flaws, which you also need to know about when purchasing it for finishing work. These include the following points:

• When cutting fiberglass sheets, small particles of fibers can damage the skin of your hands, so it is recommended to carry out this process with rubber gloves.
• In addition, when cutting the material, it is advisable to protect the respiratory organs and eyes.
• It is best to work with fiberglass while wearing clothes made of thick fabric that will cover everything. open areas bodies. In this case, you can avoid glass splinters, which cause unpleasant itching and inflammation of the skin.

Varieties of fiberglass "gossamer"

This non-woven building material is divided into three types according to its density, which can be 50, 40 and 25 g/m².

• The thinnest canvas, one square meter which weighs 25 grams, is most often used for gluing on ceiling surfaces before painting them. Therefore, this type of canvas is usually called a ceiling “cobweb”. However, due to its low density, this type of fiberglass will not be able to hide severe surface irregularities. Therefore, it is used only for relatively flat ceilings.

• Canvas with medium density, weighing one square meter of 40 grams, can be called universal. It is widely used for reinforcing and leveling both ceilings and the material is selected for pasting on surfaces that are planned to be painted in the future. Due to the high strength of this type of fiberglass, it is excellent for the lower part of walls that are especially susceptible to mechanical damage. Glued sheets will reliably protect these areas from chips and scratches. This material is also used to strengthen dilapidated ceiling plaster - it will perfectly bind and level the surface of the ceiling. This type of fiberglass is also suitable for protecting plaster on walls and ceilings in rooms with high vibration load.
• The most durable look“cobwebs” is a material with a density of 50 g/m². It perfectly covers fairly deep unevenness and relatively large cracks. A layer of this fiberglass, glued to the wall, can withstand high mechanical loads, so it becomes the best option for reinforcing walls in workshops, garages or production halls. The cost of this material is higher than that of the first two types. And in addition, when purchasing this version of the canvas, it is necessary to take into account that the consumption of glue for its installation on the surface increases significantly. In truth, there is no particular need to use this type of painting for the walls of residential premises. A material with a lower density is well suited for them.

Features of working with fiberglass and necessary auxiliary materials

In order for the finishing of walls and ceilings to have an ideal appearance, the surface for it must be prepared. Previously, this process was always carried out using putty and plaster. However, to carry out this difficult job in a dignified manner, you need to have certain skills that most homeowners do not possess. Therefore, we had to call a master plasterer who, for a lot of money, performed this rather labor-intensive work.

Now, the homeowner himself is quite capable of eliminating small defects in the walls by covering the surfaces with fiberglass “cobweb”, since this process does not require any specific knowledge and skills.

This unique material quickly and easily prepares walls and ceilings for finishing. Moreover, it should probably be clarified that the canvas can be glued to almost any surface - it could be brick, concrete, chipboard, drywall, metal or wood.

Glue for fiberglass

For high-quality gluing of this finishing and preparatory material on walls, you will need to purchase the “correct” glue and a high-quality primer solution, since the strength of holding the paintings on the surfaces will depend on them. In addition, it is necessary to observe the time indicated on the packaging of the adhesive and primer, as well as the period between gluing the fiberglass and applying the finishing finish.

It should be immediately clarified that it is not recommended to fix the canvas to the plaster mortar, since it will not be able to saturate the structure of the material well enough, so the canvas will not be firmly fixed to the surface. Liquid putty is also not suitable as glue, due to the fact that it will saturate the fiberglass unevenly, and in those places where the material is not sufficiently saturated, the “cobweb” may begin to bubble. To avoid these negative aspects, when gluing fiberglass, you need to use glue specially designed for it, which is sold ready-made or dry.

Each type of fiberglass has its own type of glue, so you need to follow the recommendations and use the composition that is intended for a specific material. However, you can also find universal glue on sale, which is suitable for all types of fiberglass “web”, but it must be diluted in certain proportions, since the canvases must be fully saturated with it.

• “Oscar” glue is intended for gluing glass wallpaper, which has a fairly high density, so it is often used for gluing “gossamer” fiberglass with a density of 40 g/m².

• Wellton glue, sold in dry form, is universal, so that it is suitable for a specific type of fiberglass; it is diluted in certain proportions indicated on the packaging.

• Kleo glue is also universal and is used not only for gluing all types of glass panels, but also for non-woven wallpaper. It is produced in finished and dry form.

In addition to these compounds, in the hardware store you can find others designed specifically for glass panels. All adhesives of this type are environmentally friendly materials and are made according to a specific formula, and their components interact well with fiberglass. In addition, they contain antiseptic substances that prevent the formation of colonies of fungus and mold.

Adhesive compositions intended for glass fabrics and fiberglass do not leave marks or stains on the surface. Therefore, if the canvas is already glued to the surface, but its impregnation shows that the applied adhesive solution It is not enough, it is quite acceptable to walk over the surface of the material with a wide brush with glue to achieve complete uniformity of impregnation.

All specifications glue can be found on the packaging, including its consumption per square meter. However, it must be remembered that the consumption of the adhesive solution will also depend on the material of the surface on which the fiberglass will be glued, as well as the quality of its pre-treatment with a primer composition. The better the surface is prepared, the less glue will be required. To guide the work time, it must be said that the period of final drying and setting of adhesives of this type is usually 48 hours.

The process of gluing the painting fiberglass “cobweb”

To glue fiberglass to walls or ceilings, you do not need any special professional skills. You just need to know the stages of the work and strictly follow the presented technological instructions. Thanks to the decision made to strengthen and level the walls yourself, you can save a decent amount, so renovation work They're not cheap at all.

Illustration	Brief description of the operation performed
	The first step is to remove the old decorative covering from the walls, if it is wallpaper or plaster that has begun to spontaneously separate from the wall.
	The cleaned wall should be carefully inspected. If wide and deep cracks are found, they need to be repaired, as they will contribute to the detachment of the material from the wall. To do this, the crack is expanded, impregnated with a deep penetration primer and dried, and then filled with sealant or cement-adhesive mortar. The surface of filled cracks must be leveled as much as possible. If there are protrusions on the wall or ceiling, quite big size, then they need to be knocked down with a hammer or cut with a grinder with a stone wheel.
	The next step is to clean the surfaces from dust and dirt - this process can be done with a brush or use a vacuum cleaner. There should be no large particles of cement or other solid substance left on the surface, such as crumbs of plaster or putty.
	Next, the surfaces need to be primed with a deep penetration solution. Such solutions, applied in two and sometimes three layers, penetrate into the wall or ceiling to a considerable depth, closing the pores in the structure of the material and promoting additional waterproofing. In addition, the primer creates a film on the surface that will create high adhesion for materials applied to it, including in this case, adhesive solution. This type of primer can also bind and strengthen weak layers of plaster. The primer should be absorbed into the structure of the surfaces and dry well.
	If serious irregularities are found on the wall, then after the primer has dried, you should try to level them using ready-made putty, which is applied with a wide spatula. However, this process is carried out only as a last resort - usually only fiberglass is sufficient for high-quality leveling. If the putty was nevertheless applied, then after it dries, the surface must be covered with another layer of primer.
	When the walls are dry from the primer, you can begin gluing the fiberglass sheets. The glue is applied to the area of ​​the wall where the material is planned to be glued. If the entire wall is covered with a “cobweb”, then its installation begins from the corner of the room.
	A canvas is applied to the area of ​​the wall surface coated with glue, and it can be of any size, since the fiberglass fits well, and overlaps, due to the thinness of the material, become almost invisible (however, you can get rid of overlaps altogether - more on that below). The canvas is pressed at the top and then smoothed out according to the herringbone principle with a special plastic wallpaper spatula. That is, first a spatula is applied with slight pressure along the center of the sheet, and then, starting from the top, from the middle they begin to push out excess glue down and to the sides, as if “drawing” the branches of a Christmas tree. The adhesive composition is absorbed into the fiberglass quickly enough, so there won’t be much excess, and it won’t take long to remove it from under the canvas. The material will immediately show how well it is saturated with the adhesive composition, but in order to prevent even the slightest possibility of its peeling, it is recommended to go over it with a roller, also moistened with glue.
	If you need to level the ceiling, it is best to carry out this process with an assistant. If you have to do this work alone, then it will be more convenient to glue the fiberglass in small pieces. To do this, a layer of glue is also applied to the surface, and then, starting from the wall, a sheet of leveling material is glued.
	After gluing the first sheet of material, the adjacent section of the wall is coated. The next sheet is applied to it, and it can be glued end-to-end or overlapped by about 40 mm. If the second option is wiped off, then immediately after gluing the second sheet from its edge, which is located on the first sheet, 20 mm is measured. Then it is applied vertically to the found points, parallel to the edge of the canvas. metal ruler or a flat wooden strip, and a sharp knife is drawn along it, cutting through both sheets. After this, the cut parts of the canvases are removed, and the edges are pressed against the wall with a spatula. Thus, you get a perfectly even joint of two sheets, which must be pressed with a roller dipped in glue.
	If the canvas turns out to be longer than necessary in length, then it is best to cut it off immediately. To ensure an even cut, the fiberglass is pressed firmly against the wall with a wide spatula, and then drawn along it with a sharp knife, as if along a ruler. If necessary, the edges of the canvas are additionally glued. TO further work You can move on to finishing the walls only after the glue has completely dried - this time is indicated by the manufacturer on the packaging.

When gluing canvases to walls or ceilings, as well as during the drying period, there should be no drafts in the room. You can't also turn on electric heaters, trying to speed up the drying of the glue, as this can lead to peeling of the material from the wall.

When strengthening walls or ceilings with fiberglass, it is necessary to carry out preliminary preparation of the surfaces, which is necessary for this material. Since such a sheathed surface has sheet joints that are somewhat recessed relative to the general level, they must be brought to the same plane using putty. Before applying it, it is recommended to prime the joints and glue them with mesh or special paper tape. The primer will increase the adhesion of materials, and the putty will be well fixed to the surface, and the reinforcement will prevent cracks from appearing due to possible movement of the wall (shrinkage, vibration, seismic factors, etc.)

Basic rules for preparing plasterboard walls for further finishing

Preparation for finishing does not end with the installation of plasterboard sheets on the walls - there is another rather complex and labor-intensive stage ahead. – read in a special publication on our portal.

After the putty has dried in the drywall seams, the entire surface of the wall is covered with a primer, which must also dry, forming a film on the surface.

After this, you can begin the process of reinforcing the drywall with “cobwebs”. Its gluing occurs in the same way as on a concrete or plastered wall.

Decorative finishing of a wall covered with fiberglass

Fiberglass is painted or covered with other materials only after it has completely dried. Walls covered painting fiberglass, can be painted without additional coating, or by first applying a leveling layer of putty to them.

If the paint is applied directly to the “web”, the structural pattern of the canvas will be visible through its layer. In addition, you need to know that you will need quite a lot of paint, since even material soaked in glue absorbs the paint composition well.

If you plan to get absolutely smooth walls, which are necessary, for example, for sticking thin paper wallpaper, then a leveling layer of putty is applied to the fiberglass.

Used for work finishing putty, which is mixed with water and mixed in strict accordance with the instructions supplied by the manufacturer, and applied to the surface with a wide spatula, starting from the corners of the room. While gluing fiberglass does not require any special skills, achieving perfect smoothness requires some skill and experience.

Some novice craftsmen succeed in this process right away, while others cannot cope with this work. To test your abilities, it is recommended to prepare a small amount of putty mixture and try to apply it to a small, not very noticeable area of ​​the wall. If everything works out, you will be able to save money on this stage of work by doing it yourself.

The putty should be applied in a thin layer of 1.5÷2 mm, trying not to leave depressions and stripes on the surface from the edges and corners of the spatula.

After applying the putty, you need to wait for it to dry, after which the surfaces are treated with sandpaper until perfectly smooth. This work can be done manually using a construction float, or used for leveling grinder(for example, eccentric or vibrating), on which abrasive paper is fixed.

If the putty is applied in two or three layers, then each of them must dry well before applying the next one.

The advantage of painting unputtyed fiberglass is that unevenness in the application of paint on it will be less noticeable, since the structure of the material is able to hide them due to its relief. However, due to the fact that fiberglass absorbs paint well, it will have to be applied in at least two layers, the second of which is applied 12 hours after the first.

It is more difficult to apply paint exactly on a perfectly smooth surface, since all color differences will be noticeable on it. Therefore, in order for the color to be uniform, sometimes it is necessary to apply the coloring composition in two or even three layers.

To paint fiberglass or putty surfaces of residential premises, it is recommended to use water-based paint, applying it with a roller with a fur attachment, and carefully and carefully tinting hard-to-reach areas of the wall and ceiling with a soft brush.

Some craftsmen, in order to bypass the stage of puttying the fiberglass, after gluing it and drying it, apply several layers of thickly mixed glue to the reinforced surface, each of which is also dried. The adhesive layer, filling the structural pattern of the surface, makes it smoother, but not perfectly flat. The adhesive layer also significantly reduces the consumption of the coloring composition.

How to choose fiberglass?

To purchase quality material, which will meet all the characteristics mentioned above, you need to choose products from well-known manufacturers.

On Russian market In the construction materials industry, products from manufacturers from Holland – “Spektrum”, Finland – “Wellton”, as well as Sweden – “Oscar” and “Samtex” have gained popularity. From domestic producers The technology for manufacturing fiberglass, in full compliance with international standards, has been well mastered by the X Glass company. It should be noted that almost all companies producing fiberglass, except for them, produce fiberglass wallpaper, and adhesive compositions for them, these products come under the general brand of the company. It is advisable to use canvas and glue of the same brand - they are completely adapted to each other.

In conclusion, I would like to remind you that the painting fiberglass “gossamer” is primarily intended for reinforcing the walls and ceilings of rooms and protecting them from the expansion of cracks that have appeared small size, as well as from the emergence of new ones. The second function that this material is designed to perform is leveling surfaces. However, many homeowners also prefer to preserve the structure of fiberglass without covering it with putty, and using it as decorative material. Thus, the “web” acquired a third function.

One cannot but agree that this multifunctional material helps solve many problems and save money allocated for interior decoration. Therefore, for many owners it can become a real salvation when carrying out any repairs - both cosmetic and major.

And at the end of the publication, traditionally, there is a video on the topic. This time, a professional finisher will share his experience of gluing fiberglass “cobwebs”.

As new trends flow into interiors, they dictate their own rules. And they apply not only to the appearance of the surrounding space, but also to its high-quality finish. Currently, when decorating premises, in particular residential ones, special importance is attached to perfectly flat main surfaces, such as walls, ceilings, corners. Several methods are used to achieve such effects. One of the most common is fiberglass. Application of this type building material allows you to create a flat surface while simultaneously acting as a reinforcing coating. It is intended for interior decoration and can be used even in recently constructed buildings that have not yet shrunk. This is what influences the formation of numerous cracks, and installing fiberglass on the surface will almost completely eliminate their occurrence.

Fiberglass - what kind of material is it?

Fiberglass is a modern finishing material that forms a completely environmentally friendly coating. Thanks to this quality, it can be used in rooms for any purpose: bedrooms, kitchens, children's rooms. It consists of fiberglass threads and organic resins. Painting fiberglass is made by gluing fibers in a chaotic manner. The fabric turns out to be quite dense without any special pattern, pleasant to the touch. Thanks to such plexuses, this material is simply called cobweb.

Based on thickness, fiberglass is divided into classes, each of which has a specific density, which varies from 20 to 65 g/m2. Depending on the selected indicator, the weight of the canvas, resistance to mechanical loads, the strength of the coating and its reliability change.

Many people are mistaken when they think, when comparing glass wallpaper and fiberglass, that they are exactly the same material. This is wrong. Painting spider web can be puttied and painted with high quality many times, and is an excellent reinforcing material.

Advantages of fiberglass

The advantages of this finishing material are quite significant:

Flaws

As a rule, any type of finish has disadvantages. Fiberglass is no exception. What kind of material is this that would not have some disadvantages? However, it is very important to correctly weigh their relationship with the benefits. The main disadvantage of the canvas is the small particles that can cause a very serious wound. In order to avoid this, it is necessary to carry out cutting only with gloves. When working with fiberglass, it is very important to protect your eyesight and wear special clothing. Such safety measures are necessary to ensure that small particles do not get on the skin, as they can cause unpleasant itching.

Fiberglass: application and surface covering

Any surface, be it a ceiling or walls, needs finishing, and gluing fiberglass can simplify this process, completely replacing the need to use starting putty. Surfaces that are often subject to mechanical damage and cracking are especially in need of such finishing. Such a fortress of this material due to specific reinforcing properties. Fiberglass is most suitable for the ceiling. It can be glued to any surface: concrete, drywall, plaster and others. At the same time, its appearance will be perfectly smooth and even. Fiberglass is also used for painting; any material is suitable for these purposes. paint material. However, in order to carry out this work correctly, it is necessary to become familiar with a certain technology. It is as follows:

1. Gluing fiberglass.
2. Surface treatment with a primer.
3. Applying putty.
4. Surface painting.

It is very important to choose the right glue and primer. The strength of the structure will depend on this. It is also important to maintain the required time interval between gluing and painting.

Glue properties

When choosing glue for fiberglass, you will need to take into account its type. This point is very important, since the strength of fixation and durability of the cladding completely depends on it. As a rule, there are many brands of glue, for example Wellton, Pufas, Bostik. Such compositions are made according to a special formula and contain only high-quality components that are completely safe for humans. They also form a film that prevents the formation of mold and mildew.

Scope of application of fiberglass

1. Used to create a waterproofing layer. Fiberglass web is often used for processing polymer canvases.
2. Roofing. Some types serve as the basis for bitumen mastics.
3. Drainage systems.
4. Pipeline protection.
5. Included in high-quality finishing materials such as Wall panels, floor coverings, etc.
6. Wall reinforcement. Painting fiberglass forms reliable protection from the formation of cracks, even those that appear due to shrinkage of the house.
7. Saving money. Thanks to the strength of this material, you can significantly increase the time between renovations in a room.

Fiberglass gluing technology

There is a certain technology for gluing fiberglass. Step by step description:

1. Treating the surface with starting putty to level out rough differences.
2. Grouting obvious defects and coating with a deep-penetrating primer.
3. Applying glue to the surface, optimal thickness layer - 1 mm. To do this, you can use a spatula, brush or roller.
4. It is necessary to start gluing fiberglass from the corner of the ceiling or walls. The joints are additionally smoothed for better adhesion.
5. Subsequent canvases are applied with a slight overlap. This place is pressed well along the entire length and after that a cut is immediately made.
6. The cut parts must be immediately removed and the ends of the canvas pressed tightly to the surface.
7. After gluing the last strip, you need to prime them. Dilute the glue for fiberglass thin enough so that it saturates the entire surface well.
8. Leave for a certain time until completely dry.
9. Putty with finishing solution and clean until perfectly smooth.
10. Prime the entire surface.
11. Proceed directly to decorating.

When gluing the fiberglass and until it dries completely, it is necessary to maintain the same temperature in the room and avoid drafts.

How to paint fiberglass?

Glued fiberglass to the ceiling or walls acts as a starting surface. It can be covered different ways, however, the most common is coloring. This process, unlike gluing, is quite complex and time-consuming both physically and psychologically.

The first difficulty lies in the specific structure of the canvas. Since fiberglass is made by pressing fibers under high pressure, there is some distance between the threads. Therefore, the paint will not apply evenly and may require further application. large quantity layers. And this, in turn, quite significantly increases paint consumption and, accordingly, financial costs.

The second nuance is glass shavings. This is what can cause a lot of problems. During staining, these particles fall off, and if the body is not protected by clothing, they will cause unpleasant itching upon contact. It is worth noting that it is quite difficult to get rid of it. It is better to immediately protect yourself by wearing a specially designed uniform for this purpose at the beginning of work.

Weighing all the difficulties associated with painting, many ask a well-deserved question: “Why use fiberglass? What will this give, what advantages?” However, the answer is clear. Surfaces with this finish are quite durable and reliable, their service life is significantly increased compared to other types, which will save on frequent repairs.

Summarizing

Fiberglass web is an indispensable thing during interior finishing work for various purposes. Its significance is quite great:

1. The canvases qualitatively strengthen the surfaces of walls and ceilings from the formation of cracks, even in buildings that are shrinking.
2. Alignment is possible without additional work related to plastering and puttying. And they, it is worth noting, are quite labor-intensive, take a long period of time and, importantly, create a lot of dirt and dust.
3. Fiberglass can act as an independent textured coating or be a reliable basis for applying finishing materials.
