Due to intense load, stains, cracks and chips form on the surface of the bathtub. When defects appear, it is not at all necessary to run to the store for a new bathtub, because it is much cheaper to restore the damaged coating using acrylic, enamel or liner. We will tell you how to restore a bathtub with your own hands, eliminate minor defects and how much such repairs will cost from specialists.

There are three main ways to restore the surface of a bathtub:

- Applying a new layer of acrylic (glass).

- Applying a new layer of enamel.

Pasting acrylic liner.

Regardless of the restoration method you choose, it is necessary to prepare the bathtub for repair.

Preparatory stage

The process of preparing a bath for renovation:

Free your bathroom from unnecessary furnishings that may interfere with the work process.
Dismantle the drain and overflow of the bathroom; to do this, unscrew the outer grilles and clamping rings on the pipes. Depending on the condition of the removed pipes and parts, purchase new spare parts in advance to replace the old ones.
Remove the baseboard between the tub and the wall.
Using coarse grain sandpaper or a drill with a special attachment, grind the surface of the bath until the gloss is removed. During the sanding process, try to remove all irregularities and loose pieces of the old coating. If the bathtub has been previously restored, then in this case it is necessary to remove the entire layer of the old coating.
Putty all the chips and holes, after the putty has dried, sand again.
Remove all debris and dust using a vacuum cleaner or damp cloth.
Cover the outside of the tub and the floor with plastic.
Wash the bathtub thoroughly with a quality detergent.
Degrease the surface of the bathtub using a solvent.

Below is a list of tools and Supplies that you will need at the preparatory stage:

Adjustable wrench.
Screwdriver.
Hammer.
Putty knife.
Putty for metal
Chisel or chisel.
Drill with sanding attachment or coarse sandpaper.
Vacuum cleaner or rag.
Masking tape.
Polyethylene film.
Detergent.

Having finished preparing the bathtub, proceed to the restoration option you have chosen.

Surface restoration using acrylic

When restoring a bathtub with an acrylic mixture, a very important factor is right choice acrylic manufacturer. After all, the quality of restoration largely depends not on the skill of the worker, but on the behavior of the mixture during pouring. Very often, the use of low-quality acrylic or hardener leads to the formation of air bubbles, smudges and peeling of the coating during further use. Therefore, when purchasing, do not save money and purchase acrylic made in Europe.

To restore a bathtub with acrylic, follow the following procedure:

Prepare the bathtub for restoration (see above).
Read the instructions for preparing the mixture indicated on the acrylic jar.
Mix acrylic and hardener according to instructions. To mix, use a drill with an attachment. Stir the mixture at low speed with the drill. Mix for at least 10 minutes.
Take a plastic cup and plug the drain hole with it.
Pour the prepared mixture into the container you will use to fill it.
Start pouring the mixture from the top edges of the bath, smoothly pouring the acrylic from the container onto the surface.
Pour the mixture around the entire perimeter of the bath, allowing it to flow freely to the bottom.
Fill the walls of the bathtub.
Take a rubber or wooden spatula and use it to evenly distribute the mixture over the edges of the bath.
Use a spatula to push the mixture that has accumulated at the bottom of the bath onto the walls again and let the acrylic drain again.
Using a spatula, spread the mixture evenly over the bottom of the bath, then remove the plastic glass from the drain hole and allow the excess acrylic to drain into a pre-set container.
Watch for the formation of smudges. If you find a leak, smooth it out rubber spatula.
If hair or debris gets on the flooded surface, remove it in a timely manner using the tip of a knife or needle.
If air bubbles are detected, lightly blow the surface with a hair dryer.
Once pouring is complete, allow the tub to dry for 48 hours.
Once the bathtub is dry, install the drain, overflow and baseboard.
Paint your bathtub with outside metal paint or cover with a decorative border.

Surface restoration using enamel

Restoring a bathtub using enamel is much cheaper than other options, but it has its drawbacks. Firstly, this is the service life of the restored surface, which is significantly shorter than that of acrylic coatings. Secondly, in order for the enamel layer to be as good as the acrylic coating, high professionalism is required when applying the enamel. Thirdly, enamel is more susceptible to mechanical damage than acrylic.

If, despite all the shortcomings, you decide to restore the bathtub with enamel, then do the following:

Prepare the bathtub for renovation (see above).
Read the instructions on the packaging of the purchased enamel. There are two types of enamel, ready for use and requiring the addition of a hardener.
Mix hardener and enamel in the proportions specified in the instructions.
Please note that the enamel surface is applied to the bath in two layers, so you will need two cans of enamel. The second can of enamel is opened and mixed with hardener only after the first layer has dried.
Using a wide brush, apply the first coat of enamel to the bathtub. Try to apply the enamel without leaving streaks or smudges. Promptly remove debris and brush hairs that have fallen onto the surface.
Due to the increased load on the bottom of the bathtub, it needs to be painted twice.
After the first layer has dried, mix a second can of enamel with hardener.
Apply a second coat of enamel to the tub.
Each manufacturer has its own time for complete drying of the enamel; you can find it in the instructions or on the packaging. After the enamel has completely dried, install the drain, overflow, baseboard and decorative edge.

Restoring a bathtub using a liner

The main problem with this restoration option is selecting a liner that exactly matches the shape of your bathtub. This problem is especially acute for owners of antique and non-standard bathtubs. If you have a standard and relatively new bathtub, you will not have problems finding an insert.

To install the liner you need to do the following:

Prepare the bathtub for restoration as described above.
By using electric jigsaw or hacksaws, cut off the safety edge from the edges of the liner.
Place the liner in the bathtub and mark the drain hole and overflow.
Remove the liner from the bathtub and drill holes according to the markings.
Sand the edges of the holes with fine-grit sandpaper.
Apply sealant around the edges of the drain and overflow.
Apply strips of polyurethane foam with a low coefficient of subsequent expansion over the entire surface of the bathtub. The stripes should be located at a distance of 15-20 centimeters from each other. Under no circumstances use regular polyurethane foam, this may cause the liner to become deformed.
Install the liner on the bathtub and install the drain with overflow.
Fill the bathtub with water to press the liner more tightly to the bathtub.
Leave the bath with water for 24 hours until the foam dries completely.
Drain the water and remove the protective film from the liner.
Install a baseboard and a decorative edge on the bathtub.

Installation of the liner is complete!

Correction of minor defects on the surface of the bathtub

If one or two small chips appear on the surface of the bathtub, or small cracks, produce complete restoration not entirely reasonable. In such cases, it is enough to make minor repairs and eliminate defects.

Repairing chips on a cast iron bathtub

For repair you will need:

Automotive putty.
Enamel of the same color with coating.
Sandpaper.
Solvent.
Brush.
Putty knife.

Dry the chipped area and sand it with sandpaper. Pry the edges of the chip with a knife and remove the loose pieces of enamel. Degrease the surface of the chip with solvent and cover it with automotive putty. After drying, the level of the putty should be slightly below the level of the enamel. Sand the putty area with sandpaper. Using a brush, apply a layer of enamel to the putty. After the enamel has dried, you can use the bath again.

Repairing a chip on an acrylic bathtub

The acrylic sheet from which the acrylic bathtub is made is quite resistant to mechanical damage. But there are times when, due to objects with sharp corners falling into the bathtub, chips form on the surface and the need for repairs arises.

To remove a chip in acrylic bath you will need:

Acrylic of the same color as the bathtub cover.
Hardener.
Solvent.
Rubber spatula.
Fine-grit sandpaper.

Dry the chipped area and sand it with sandpaper. Remove dust and degrease the chip with a solvent. Mix a small amount of acrylic with hardener. You need to get a mixture of strong viscosity, otherwise the acrylic will leak out of the damaged area. Apply the mixture to the chip using a spatula and level the surface and the damaged area. Allow the acrylic to dry for 48 hours before you can use the bathtub.

Removing stains and rust

Usually, to remove stubborn stains and rust from the surface of the bathtub, it is enough to use a high-quality detergent. But in particularly difficult cases, you can use hydrochloric acid to remove contaminants.

Apply the acid to the contaminated area for 3-5 minutes. After this, wipe the area with a washcloth until the stain disappears and rinse off the acid with water.
Please note that hydrochloric acid emits toxic fumes and can burn the skin, therefore, when working with it, you must use gloves, safety glasses and a respirator.

Replacing a bathtub is a very expensive and troublesome undertaking, associated with great difficulties and quite significant financial costs. That is why most of those who have started a renovation (especially not a major one, but a cosmetic one) are looking for alternative ways to make it look better again. sanitary product neat look. How to restore an old one cast iron bath- the masters of this field certainly know. But it’s quite possible to do most of the work yourself.

When is it time to renovate your bathtub?

A cast iron bathtub is the standard of quality, strength, and reliability in the plumbing world. It’s not for nothing that they recommend installing products made from this alloy in apartments. Many houses built back in the Soviet Union had just such bathtubs installed. Moreover, such baths are still used today. Also, a cast iron product is comfortable to use: it does not create noise, unlike, for example, a thin-walled iron bathtub. And it’s nice to wash in it - the bath retains the heat of the water poured into it much longer than others.

Unfortunately, even seemingly eternal things wear out over time. And a cast iron bath is no exception. In this case, it is not the structure itself that deteriorates, but the coating – the enamel, with which the structure was coated at the factory. And now this special paint, applied using a special technology, begins to lose its appearance, and its performance characteristics are getting worse.

On a note! During production, cast iron bathtubs are coated with enamel after strong heating. It is due to this that it is possible to obtain high-quality adhesion of the base to the coating.

Signs that it's time to update your bath are listed below.

Internal surface roughness. It is much more pleasant to step on smooth enamel than on pumice-like enamel.
Cleaning the bathtub is becoming increasingly difficult. The reason is the same rough surface on which it no longer glides easily and pleasantly. regular sponge. It takes a lot of effort to clean a bathtub.
Dirt and rust quickly and strongly eat into the enamel due to loss of smoothness. In some cases, contamination cannot be removed completely.
The appearance of chips and cracks on the surface of the enamel.

Attention! Enamel chips are dangerous for the entire structure. The fact is that enamel paint protects cast iron from exposure to water and aggressive chemicals for cleaning plumbing fixtures. Rust forms quite quickly in places where there are chips and gradually begins to spread throughout the entire structure right under the enamel.

It is these signs that inform the owner of the bath that it is time for her to “rest.” But don’t rush to dismantle it and throw it away - the bathtub can be revived! And for this there are three quite simple and also relatively inexpensive way– this is the use of an acrylic liner, the “fill-in bath” technique and renewal of the enamel.

Three ways to update your bath

All these methods differ from each other in price, quality, speed of work and complexity of implementation. But it’s worth considering them all to choose the one that suits you best. Each method has its own advantages and disadvantages, which are important to know in order to make the right choice.

Painting the bath

Self-enamelling or, more simply put, painting the inside of the bathtub with special coloring compounds in order to renew the coating is one of oldest methods restoration, which has already stood the test of time.

The work is carried out using a brush and special kits for restoration, which include directly and a hardener for it; the kit can also contain tints of various colors that will allow you to change the color of the bathtub and make it as harmonious as possible in a certain color scheme interior By the way, you can buy such coloring pigments yourself, and then simply add them to the coloring composition diluted according to all the rules.

The paint is applied to the surface of the bathtub, previously cleaned of dirt and rust. Before starting work, it is advisable to sand the walls using grinder, wash, and then degrease with any means (for example, acetone).

Important! Before the enamel is applied, the bath is well heated. This can be done using a hairdryer or by pouring hot water into it. However, after using the second method, the surface of the structure will have to be thoroughly dried. Otherwise, the paint will not adhere as it should.

It is most convenient to work with a brush, but there are also compositions that can be perfectly applied to the surface of cast iron using a small paint roller. There are restoration compositions for enameling bathtubs and aerosol cans, but they are not recommended for use on large areas, since the paint coming out of them often lies unevenly on the surface, and therefore drips may remain. By the way, some compositions, especially professional ones, may have increased or decreased fluidity, which can complicate the work of a beginner. Therefore, it is worth buying non-professional kits.

Attention! All compounds used for enameling bathtubs are very toxic, and therefore it is important to work in a respirator and rubberized gloves. It should also be ensured good ventilation in the apartment and remove children and animals from the house.

It will take about a week to completely restore the bathtub using this method. The fact is that the enamel is applied in several layers, and each of them should be thoroughly dried before applying the next. TO , You can read in our article.

Acrylic liner

This method of restoring bathtubs is actively used for cast iron products and is otherwise called “bath in bath.” A custom-made or purchased ready-made acrylic liner is inserted inside the old structure, which follows the contours of the plumbing structure. It is fixed inside with foam or special mastic, which is applied to the inner surface of the bathtub. In this case, it is necessary to dismantle the plumbing parts for drainage.

Advice! For high-quality adhesion of the adhesive substance to the surface of the bathtub, it is best to clean and degrease it (the surface).

The acrylic liner is solid, so first it is inserted into the bathtub without glue, holes for drainage are marked, after which they are removed and these holes are cut. Then, after applying adhesive composition on the inner surface of the bathtub itself, lower the liner there and glue it.

Table. Advantages and disadvantages of the method.

Advantages	Flaws
Acrylic is a very durable substance; such a bathtub coating will be stronger than enamel.	The need to dismantle plumbing equipment.
The liner does an excellent job of hiding all the unevenness and damage to the bathtub, making it smooth and beautiful.	Cannot be installed on structures made of thin metal. Such metal can bend under the weight of water and people, which is why the adhesive adhesion of the liner to the surface is easily broken.
Acrylic does not turn yellow over time.	Quite a high price.

The service life of the acrylic liner is approximately 15 years. However, this restoration method is much more expensive than the previous one.

Acrylic coating

This method is otherwise called “fill bath”, because it is performed using a special technology using liquid acrylic. The substance is poured onto the prepared surface old bath. This is a fairly durable coating that resists daily exposure well, but still requires careful cleaning without the use of abrasives.

On a note! Due to its relative thickness and viscosity, liquid acrylic can be used to mask unevenness during bathtub restoration.

“Fluid bath” is enough new method restoration, but has already become a favorite of many, since it does not force plumbing owners to completely replace a cast-iron bathtub, but can be done easily even with their own hands.

Filling bath - before and after

The advantages of the method lie in the durability of the coating, since acrylic is applied in a fairly thick layer - about 5-6 mm. By the way, despite its thickness, it spreads well over the surface of the bath. It is also very pleasant to the touch and smooth.

How to properly restore a bathtub using this method? It's simple - follow our instructions.

Step 1. First you need to prepare the bath for work. Using a grinding machine, the old enamel coating is sanded to a rough state.

Step 2. The bathtub is cleaned with a powder and a sponge, and then rinsed with clean water.

Step 3. The drainage system is dismantled both at the top and at the bottom of the bath.

Step 4. The surface of the bathtub is degreased using any degreaser. Acetone will do, as will any other solvent. After this, liquid acrylic is prepared according to the instructions indicated on the package. The mixture must be stirred very thoroughly.

Step 5. It's time to start filling the bath. For ease of work, a little acrylic can be poured into a small container. To avoid staining the floors, the container is placed in the bathtub.

Step 6 Acrylic is poured onto the surface of the bath in a thin stream, starting from the corners and edges of the bath in a circle.

Step 7 The substance is poured in several layers. It should flow down the walls of the bathtub, evenly covering the sides and top.

Step 8 Using a spatula, the acrylic layer is leveled, starting from the middle of the bathtub to its bottom. All “gaps” are covered. The acrylic is lifted with a spatula from the bottom of the bath. In this way, all the side walls and bottom are worked out.

Step 9 The bath is left to dry - this period is at least 36 hours. All this time it is better not to touch it at all, otherwise you can ruin all the work.

Step 10 Lastly, when the acrylic dries, a drain system is installed.

Now you can use the product for your pleasure. The service life of a “fill-in bath” varies from 8 to 15 years.

Video – “Floating Bath” Technique

Compositions for “fill bath”

A “fill bath” can be made using two types of media – glass acrylic and liquid acrylic. They are different from each other, and a common mistake for beginners is to mistake them for the same substance.

Stakryl began to be used about 10-15 years ago. It is relatively inexpensive and has fairly high strength. After applying it to the bath, it should be dried for at least 4 days - and already here you can see a clear difference between the substance and ordinary liquid acrylic, which has a shorter drying time. Also he is afraid of glass mechanical damage, therefore, it is important to handle the bathtub covered with it carefully and carefully.

Liquid acrylic, on the contrary, has appeared quite recently on the construction products market. It has higher strength and resistance to various mechanical stress. The coating made from it retains a glossy shine for a long period of time. By the way, the smell from it is much less pungent than from glass. Acrylic takes only 36 hours to dry.

In general, both materials can be used for the restoration of bathtubs and other plumbing fixtures. But you should definitely know the difference between them.

Summing up the results of what has been said, we can confidently note that anyone can restore a bathtub with their own hands, restore its former grandeur and neat appearance, even without the use of drastic measures to replace the bathtub itself. But the service life of such updated products (or rather, their coating), of course, is not so long.

Acrylic bath liner - installation steps

Filling bath - before and after

Sooner or later, the enamel of any bathtub becomes thinner, indelible rust stains appear on it, and its owner is saddened to note that it is time to change the equipment. This difficult procedure is very labor-intensive, so many are trying to figure out how to update an old cast-iron bathtub and whether it is even possible. Despite the fact that the appearance of such a device leaves much to be desired, the design fully retains all its performance characteristics. Therefore, restoration should consist only of applying a new enamel coating. Modern technologies allow you to do this.

Is it worth restoring old equipment?

The most obvious solution is to replace the plumbing equipment. Let's try to estimate how much such an event will cost. To the cost of the simplest bathtub we add the costs of transporting it and lifting the device to the floor, if required. In addition, a certain amount will be required to pay for the dismantling of old equipment and installation of new equipment. At the lowest prices, all this will require about 12,000 rubles. This is only the case when the wall and flooring will not be damaged by installation work. Otherwise, you will also have to pay for partial bathroom renovations.

Removing an old bathtub and installing a new one is a troublesome and expensive undertaking. If the enamel of the equipment has become thin or washed away, but the device itself is still in good condition, it’s worth thinking about restoration

Thus, for a fairly large sum, we get a modest result, since the cost of the cheapest bath was included in the calculation. If you want something more convenient or high-quality construction, you will have to increase the estimated cost item. Not everyone can afford such costs, so they want to restore their cast iron bathtub. This is a cheaper and more effective solution.

However, it is very important to choose the restoration method wisely. There are only three of them:

covering the bathtub with acrylic;
applying a new layer of enamel to the surface of the device;
installation of acrylic liner.

Let's look at each method in more detail.

What restoration methods exist?

Option #1 - acrylic coating

Restoring a cast iron bathtub by “pouring” acrylic is considered one of the simplest. This is a fairly new method that has gained popularity among consumers. It consists of applying a liquid acrylic solution by pouring onto the surface of the equipment. Its advantages include:

Durability. The coating obtained in this way, provided it is applied correctly, retains its properties for about 8-15 years. This is due to the fact that acrylic is applied in a fairly thick layer of about 6 mm.
Smooth glossy finish. The composition is quite thick. It spreads well over the surface of the device, filling possible irregularities, forming an almost perfectly flat and smooth plane.
Relative simplicity and high speed applying liquid acrylic.
Absence unpleasant odor, which allows you to perform work even in homes where allergy sufferers, children and the elderly live.

There are also disadvantages of the method. These include the drying time of the composition. This usually takes about three days, during which it is not recommended to even approach the device. Because debris, dust particles or water accidentally falling on the drying surface can ruin it.

Despite the apparent simplicity of applying acrylic using the pouring method, it is a rather complex method of restoration. Requires certain skills to work with composition

Another negative point– relatively high cost. It is higher than that of enameling. However, this price is fully justified by the longer service life and good quality coverings.

Option #2 - do-it-yourself enameling

Most old way restoration. It vaguely resembles painting, but you need to clearly understand that in this case special enamel is applied. This is exactly what you need to choose when wondering what you can use to paint a cast iron bathtub. There are two types of such compositions: for professional application and for self-application. The first ones are very liquid and require laying in several layers. This is a rather complicated procedure. The second ones are thicker and, accordingly, easier to apply.

The correctly selected composition is applied using a roller, or more often a brush, onto the prepared surface of the equipment. Advantages of this method:

The cheapest restoration option.
There is no need to dismantle and subsequently install the drain and overflow.
Suitable for both cast iron and steel bathtubs.

Enameling has many more disadvantages:

The service life of new enamel is about 5 years.
The composition applied to the surface of the equipment takes quite a long time to dry - about 5-7 days.
The coating is hard and therefore very sensitive to impacts. Over time, chips may appear.
The enamel is applied in a fairly thin layer, so it is not able to cover various surface irregularities such as dents, chips, etc.
Over time, the epoxy coating will inevitably turn yellow.

You need to understand that the enamel obtained as a result of restoration is significantly different from the one that was originally applied to the equipment.

Cold enameling is the cheapest and easiest method of restoration. It resembles painting the surface with a special composition

To ensure that the enamel lasts as long as possible, you should: simple rules. For example, to clean an updated cast-iron bathtub you will need not abrasive powder, but a mild soap solution. Otherwise the enamel will be damaged. The device should be protected from impacts, especially with sharp objects, and do not pour too much water into it. hot water. When filling the container, first open the tap cold water and only then - with hot.

Option #3 - “bath to bath” method

This is the name of the restoration method, which consists of installing an acrylic liner inside the old structure that completely follows its contours. The insert is mounted on a special adhesive foam. With proper work, the service life of the bathtub after restoration is about 15 years. The main advantages of the method:

Durability of the new coating. Acrylic is much stronger than enamel.
A smooth surface that hides all defects of the old structure.
The surface will not turn yellow over time.
A successful combination of the advantages of an acrylic and cast iron bathtub.

The disadvantages of this method include the need to dismantle drain siphon and a ban on the installation of inserts in thin structures, which are called “light cast iron” or “thin cast iron”. This is due to the fact that the equipment may sag and the adhesive layer securing the liner will be damaged. The “bath to bath” method is very demanding on the quality of materials. Using insert Low quality or using unsuitable glue, it will not be possible to restore the bathtub.

Installing an acrylic liner is easy and effective method restoration. Particular attention should be paid to the size of the insert. It should fit the bath perfectly

All three methods require preparing the equipment for the update. This step usually involves cleaning the cast iron bathtub from dirt and grease. Degreasing is done using oxalic acid or baking soda. All defects are carefully cleaned so that the surface is smooth. Then grinding is carried out. The result should be a rough surface. When applied to it the required composition adhesion with it will be maximum.

To restore or not - objective conclusions

The decision to restore or replace an old bathtub, of course, will be made by its owner. However, you need to know that if you carry out restoration work correctly and use only quality materials, the updated bathtub will last for a long time. It may be worth entrusting this task to experienced specialists with a good reputation. Then for relatively little money you can get excellent results.

Liquid acrylic – modern material, with which you can carry out high-quality restoration of the bathtub with your own hands. It consists of a base having a fairly high density and a hardener. Can be used for the restoration of steel, cast iron and acrylic bathtubs.

Materials and tools

To restore the bathtub, you will need bulk liquid acrylic, cleaning and degreasing products for plumbing fixtures, and soda. Please note that liquid acrylic is sold in containers designed for bathtub sizes - 1.2, 1.5 or 1.7 m.

You need to prepare a tool for work:

grinder;
drill;
whisk attachment;
pliers;
sandpaper of various grain sizes;
rubber spatula;
respirator;
vacuum cleaner;
sponge;
gloves;
flashlight.

When using a drill to sand the surface of the bathtub, you will need a special attachment.
Note: construction hair dryer and a stationery knife will be useful for removing non-factory enamel if the bathtub has already been restored.
You also need polyethylene to protect the floor and walls (you can use rags or newspapers).

Preparing the bath

The appearance and service life of the applied coating will depend on the quality of preparation. First, the overflow and drain are removed. Using a grinder or a drill with a grinding attachment, you need to carefully treat the surface of the bathtub. For this, sandpaper for rough work 40-N or 32-N is used (according to GOST 3647-80). Emery will also help remove any water deposits that have formed. The surface after sanding should be rough to ensure good adhesion of liquid acrylic.

Note: non-factory enamel, previously applied to restore the bathtub, is removed with a utility knife after heating with a hairdryer.

The bathtub needs to be cleaned and any remaining debris removed. Then the surface is treated with a plumbing cleaner - the poured product must be spread with a sponge over the entire surface of the bathtub, including the installation location of the removed overflow.

The bath is washed again and left to dry. After drying, proceed to the next important stage works - degreasing. Soda is poured into the bath and thoroughly rubbed over the entire surface with coarse sandpaper.

Perhaps degreasing will need to be done not once, but two or three times. You must work with gloves. Then the bath is thoroughly washed with a stream of water from the shower.

Before starting the next stage, you need to remove the siphon.

The installation site of the siphon must be cleaned, degreased and rinsed from soda residues.

The mixer and shower are covered with a bag and secured with tape - water should not get on the applied layer of liquid acrylic until it dries completely. The tiles and shelves above the bathtub are cleaned of dust particles with a cloth. Do not allow sanding dust to get on the acrylic.

After completing this stage, the bath should be thoroughly dried with a hairdryer. Particular attention is paid to places where water can collect: the joints of the tiles and the bathtub, under the side, which is installed at the junction of the tiles and the bathtub. It is better to remove the rim and carry out the restoration of the bathtub without it. The cement joints at the junction with the bathroom can be dried well with a hairdryer.

To eliminate defects in factory enamel (cracks, chips), use quick-drying automotive putty.

The composition is stirred and applied to the damaged areas with a rubber spatula, after which it is allowed to dry.

While the putty dries, cover the floor under the bathtub and the tiles at the joints with polyethylene or newspapers, which are secured with tape.

So, when pouring liquid acrylic, it will not spoil the flooring and wall tiles.
After the putty has dried, these places are covered with fine sandpaper. Use a vacuum cleaner to remove dust particles from the bathtub.

Use a degreasing agent (acetone) to wipe the areas where cracks and chips have been putty. You should also wipe the installation areas of the overflow and siphon with acetone. Place a container under the drain hole (you can use a cut plastic bottle). Excess liquid acrylic will drain into this container.

Coating

After completing the preparatory work, they begin to prepare liquid acrylic. The hardener is added to the material in parts and thoroughly mixed using a drill with a whisk attachment.

It is necessary to achieve complete mixing of the two components, not forgetting about the material in the corners and at the bottom of the jar with liquid acrylic. Otherwise, the layer of applied acrylic will dry unevenly. You need to stir the mixture for 10 minutes.
Important! Do not forget about the pot life of the finished mixture, which is indicated on the packaging. During this time, you need to completely complete the work.
Before pouring the composition is allowed to stand for 5-10 minutes. To work you will need plastic container, into which acrylic is poured. You can use a trimmed and well-wiped hardener bottle. The work is performed wearing medical gloves.
Note: adding coloring paste will allow you to obtain the desired color of the composition. Color paste by weight should not exceed 3% of the total mass of the composition.
The composition is poured around the perimeter of the bath from top to bottom.

Going lower, help yourself with a rubber spatula, with which the acrylic is rubbed into the surface of the bath. Having achieved complete coverage with liquid acrylic, use a spatula to make zigzag movements along the bottom of the bath. Then the composition is leveled with even movements from the wall towards the drain.

The bath is left for 5 minutes. Turn off the light and use a flashlight to check the surface of the bath for defects or irregularities (smudges) that need to be leveled with a spatula.

Important! Air bubbles may have formed when mixing the composition. To remove these bubbles, the surface of the bath is quickly blown with a hairdryer at low speeds.
After 10 minutes, use a flashlight to check the surface again. The bathtub can be used 24-48 hours after complete drying. Until this point, the bathroom must be closed. The drying time of the composition depends on technical characteristics material and temperature regime in room.
Note: Some modern liquid acrylics take 12-16 hours to dry.

Result of the work

As a result of the work done, you will receive a completely restored bathtub with a beautiful appearance, which is guaranteed to last at least 10 years. After each use, the bathtub should be washed with special acrylic care products, dishwashing detergent or liquid soap.

Advantages and disadvantages

Advantages of bathtub restoration with liquid acrylic:

long service life;
beautiful appearance;
smooth surface;
excellent performance characteristics, first of all mechanical strength;
possibility of repeated restoration in the future.

A bathtub after restoration will be practically in no way inferior to a new bathtub.
The disadvantages of this technology include:

the long time required for the surface to dry completely;
a specific smell when applying and drying liquid acrylic;
the need to purchase bath care products.

Tricks at work

A high-quality bathtub surface will be obtained by applying the composition in an even, thick layer. Acrylic should flow down on its own. Determine by eye the middle of the side slopes and pour a second portion of the composition onto them. The remaining material is poured to the bottom. This way the entire surface of the bath will be covered with a thick layer of acrylic.

Properly done enameling of a bathtub with your own hands makes it possible to save considerable money that would have to be spent on purchasing a new product and installing it.

Restoring a bathtub - will it help restore its former beauty?

Over time, steel and cast iron bathtubs begin to lose their attractive appearance. They become rough, the gloss disappears from them, traces of corrosion appear in the bowl and smudges form that cannot be removed with household chemicals. In such situations, it becomes clear that the bathtub requires replacement, which costs a lot of money. Self-restoration (simple repairs, often called restoration) of structures for water procedures allows you to avoid serious costs.

Operational wear of the enamel coating is due to two reasons:

Using various chemicals for cleaning communications through which water enters the home.
The use of cleaning compounds with chlorine additives and abrasive powders.

Under the influence of these aggressive drugs, the enamel on a cast iron bathtub deteriorates after 9–10 years of operation of the structure. Self-repair of the coating extends the life of the structure by another 6–10 years. In order to qualitatively restore a bathtub, you need to purchase special means, ensuring easy restoration of its enamel, and also study the principles of implementation repair work. We will talk about them in this article.

Note that all the proposed methods for restoring the coating of a cast-iron bathtub are carried out without dismantling the structure.

Today the restoration of bathtubs on our own carried out in the following ways:

restoration of the bowl's coating using liquid acrylic;
applying new enamel (standard enamel compositions are used);
restoration by installing an insert into a worn bowl.

Any of these methods demonstrates excellent results. If you do the repairs correctly, your updated bathtub will serve you for many years to come.

Simple enameling is an elementary method of restoration

Repairing a bowl by applying two-component enamel to its surface, which additionally includes a special hardener, is quite a simple task. This operation is performed in two stages. First you need to prepare the surface of the bath:

Pour abrasive powder onto the old coating and use grinding wheel(it must be secured in) or sandpaper (the work will have to be done manually) clean the bowl.
Areas with ingrained rust are treated with compounds designed to transform corrosion stains. Then you pour the rust converter onto the problem areas and leave them in that state for 30–40 minutes.
Use pressurized water to wash off the old enamel.
Use a lint-free cloth to degrease the bowl (any degreasing compound sold in hardware stores will do).
Pour hot water into the bath and leave for 10-15 minutes.
Drain the water and carefully wipe the bowl with the same lint-free napkin.

Now we are waiting for the actual restoration of the cast iron (or steel) structure. We take the purchased two-component enamel composition, combine its components (hardener and enamel itself) in the proportions recommended by the manufacturer, and actively mix. When the composition is ready, apply it with a sprayer or on the surface of the bowl.

After this, you should wait a while (it is indicated in the instructions for the enamel composition) and reapply the enamel to the surface. In principle, the restoration of the coating is considered complete. You will have to wait (do not use the bathtub for 6-8 days) until the polymerization process of the enamel composition is completed. The new coating provided by the described restoration of a cast iron structure will serve you for at least 6–8 years.

Liquid acrylic - a modern option

You can restore a bathtub using a new method. It involves the use not of two-component enamel, but of more effective glass acrylic, which is a special acrylic composition created to return enameled metal structures their former splendor and beauty.

Glasscryl has several important advantages, it:

is able to independently (with minimal participation of the person performing the repair of the structure) lay down in a perfectly even layer on the surface of the bowl and envelop it;
characterized by an ideal viscosity indicator, ensuring a durable and reliable coating up to 6 millimeters thick.

Note that the impact and mechanical strength of the acrylic layer is significantly higher than that of standard enamel. Considering this, it becomes clear why self-recovery cast iron and steel structures Nowadays, it is increasingly performed using glass acrylic. Old enamel When using liquid acrylic, it is removed from the bowl according to the scheme given above. There are no differences. After cleaning the bathtub, you only need to place a container under its drain to collect excess acrylic and turn off the siphon.

The restoration itself will be carried out like this:

prepare the composition for restoration (strictly according to the recommendations of the glass acrylic manufacturer);
start pouring it (very slowly) onto the top edge of the bowl;
when the stream of solution reaches the middle of the bath, you need to start moving it (as smoothly as possible) along the perimeter of the structure;
Having completed the full circle, stacryl should be reapplied according to the described method.

This type of restoration is called self-leveling restoration. It should be done continuously. Therefore, for liquid acrylic you should always take a container large enough so that the composition in it is enough for the entire bath. The excess glass will go down the drain, under which you will place another container. The process of complete polymerization of acrylic compositions takes 24–96 hours. It all depends on what specific mixture you buy.

Experts advise using formulations that have the longest drying time (3-4 days). They have been proven to provide a better, more durable surface that can last up to 18-20 years. One more subtlety. If you want to get a stacrylic coating of any specific color, you can add about 2-3% tinting paste to the composition. It will provide the bath with a muted, light shade. Please note that more than 3% of the paste cannot be added, since the strength of the stacrylic layer in this case will significantly decrease.

Bathtub liner - an expensive but simple type of repair

People who do not want to dilute enamel or liquid acrylic, apply these compounds to the surface of the bowl, and wait for them to polymerize, can be advised to order a special liner according to the size of your design for water procedures. Typically, such products are manufactured at enterprises that produce bathtubs.

Having received the liner, you will need to perform a number of simple works:

Clean the bathtub and degrease it thoroughly.
Install the liner into the bowl (if you specified it geometric parameters That's right, there are no problems with this procedure).
Trim the resulting product along the line of the tiles on the wall.
Apply adhesive to the outer parts of the liner and to the inner bowls.
Carefully connect the drain holes of the bowl and liner.
Seal the joints with silicone.
Pour cold water into the bathtub with the liner installed for 24 hours.

After a day, drain the water - the repair is complete. Use your updated bathroom for another 8-10 years!
