Bathroom supply store New Bathroom Style knows the enamel coating of modern bathtubs is considered one of the most resistant to water and, at the same time, quite vulnerable to accidental impacts with sharp and hard objects. After ten to fifteen years of service, the owners inevitably face a dilemma: – buy a new one or do the restoration of the bath on their own how to restore the enamel of the tub so that, without changing the mode and method of use, you do not think about restoration for at least five years. If you need unique bathroom vanities or 24″ or 36 inch bathroom vanities, welcome our web bathroom supply store and make your choice.
METHODS FOR RESTORATION OF BATH ENAMEL COATING
The most radical and effective way to bring an old bathtub with worn enamel back to life is to completely replace or restore the enamel coating in a paint shop. The restoration method with polymer-ceramic paint requires autoclave drying, so it is resorted to only when the bath is of interest due to its antique value. In all other cases, bathtub restoration is carried out at the installation site, especially if the bathtub is made of cast iron or natural stone, such as malachite.
The planned scope of work directly depends on the quality of the enamel and the technical condition of the bath: Whitening, complete cleaning, and whitening of the enamel; Spot repair of chips and scratches; Full restoration of enamel in the bathroom. Traditionally, at-home bathtub refurbishment is done for cast iron and acrylic bathtubs. Steel cases are restored less often, only if there is economic feasibility. For example, if enamel was accidentally chipped or pitted in a new bathtub.
Restoration methods for a cast-iron bathtub can be successfully applied to a steel structure. The only thing that needs to be done before restoring the enamel in the bathroom is to strengthen the steel body. Advice! It will be necessary to make additional brick supports rigid enough so that the steel bath gets maximum stability and does not give deflection and twisting of the body when the bowl is filled with water. It is crucial to do this before starting the restoration to prevent the peeling of the repair coating. In addition, it is essential to complete the entire range of preparatory work so that there is perfect sterility and cleanliness during the restoration process in the bathtub.
MINOR WALL REPAIRS IN THE BATH
The most vulnerable of all types of bathtubs are acrylic structures. During the restoration process, the acrylic coating must be cleaned of dirt and polished scratches. Cleaning can be done with ordinary dishwashing detergents. It is enough to rinse the tub with clean water and dry it to a “squeaky” surface. Restoration involves polishing the coating in the bath. To do this, use a set of soft felt circles of small diameter, a screwdriver, and a polishing paste. Before restoration, the bottom and walls must be covered with a soft cloth so that scratches are not accidentally added when working in the bath. Scratch elimination is carried out in the following sequence: The Shurik regulator is set to low speed so that polishing drops do not scatter in the bath; The end surface of a soft rag circle is treated with a paste; Treat the scratch with polish and overwrite the damaged area. The axis of rotation of the nozzle with a process should be parallel to the scratch line. Advice! It is essential not to burn or put dirt into the crack when polishing. Otherwise, the result of the restoration will be precisely the opposite. The bath will turn out with a dirty spot on the wall. To restore scratches in the bath, white polishing pastes for acrylic and PVC plastic are used. It will take at least half an hour for a small scratch. The main thing is not to press and not to rush. Restoration does not like haste.
RESTORATION OF THE ENAMEL SURFACE WITH ACRYLIC
Restoration of the bathtub with liquid acrylic makes it possible to obtain a coating with the best characteristics. The bath is almost like new. With high-quality preparation and adherence to technology, walls with acrylic look no worse than natural enamel.
PREPARATION FOR APPLYING THE COATING
Two factors depend on how conscientiously the bathtub is prepared for restoration – the quality of adhesion to the enamel and the uniformity of the coating. To restore the bathtub with acrylic, you will first need to remove all the dirt that has eaten into the pores of the enamel. If the bath has no chips or scuffs to the metal, the overall thickness and condition of the enamel are satisfactory. Then you can limit yourself to deep cleaning and grinding the walls. The bath is washed using liquid soaps. It is best to use a potash or a special one for cleaning tiles. To simplify preparing for the restoration, deburring can be done with a cup brush with propylene bristles mounted on a shaft.
The most specific device on an electric drill with soda or a cleaning agent allows you to clean the bath in an hour and a half. After cleaning, the bowl is thoroughly washed to remove soda or cleaning powder residue left on the enameled surface. Next comes the most crucial stage of preparation. Using a solid lamp or flashlight, check the condition of the enamel. If the surface cleaned of dirt does not have black metal stains or chips, you can proceed to prime. Whether steel or cast iron, the exposed metal must be treated with a solution of zinc in phosphoric acid before restoration, dried, and shaded with acrylic. After 6-10 hours, the patch is ground with emery and polished around. The bath must not be left with chips that have sharp edges. Any defect must be shaded for a smooth transition. Otherwise, after applying a layer of acrylic polymer, the chips will show through the new enamel.
APPLY ACRYLIC COATING
Best of all. The two-component acrylic resin is suitable for restoring and repairing a metal bowl. A one-and-a-half liter resin container with a hardener is bred in a clean, dry container. The latter is poured into the resin in a thin stream and thoroughly kneaded for 6-7 minutes. Spatula. Before applying the acrylic mass, the bath along the side is pasted over with construction tape. The resin will not get on the tile floor tile, thanks to the video. While restoring the bath, the cast-iron body must be thoroughly warmed up. This will speed up the polymerization of the resin.
The steel case can be left unheated. It will still cool three times faster than the setting time of the resin. Next, we release the water and remove the drain system. We remove the remaining water with a clean napkin. We substitute a container under the hole in the bottom to drain excess resin. The acrylic composition in the bath can be applied with a brush or wall pouring. In the latter case, the material is run in a thin stream along the upper edge, and the resin flows down the sidewalls and forms a continuous sheet of acrylic mass. Not earlier than 5 hours later, the second layer is applied. Experienced artisans manage with two layers poured into the bath, but restoration has to be done in three layers without skills.
The best option for applying acrylic is the first layer, the thinnest, used with a spray or brush. The resin is dried until completely removed. The defects are trimmed and carefully cleaned; The second layer is applied in bulk; The third layer is used with a sprayer in places where the acrylic thickness is visually thinner. You can apply all layers to the bath with a spray gun, but in this case, the coating is relatively light. Since the mixture is prepared for spraying more liquid, there is a risk of streaks. At the final stage of restoration, dried marks on the edges of the drain hole are removed, and the bellows are collected in the bath. This can be done no earlier than a day after laying the last layer in the bath.
UNIVERSAL MATERIAL FOR RESTORATION OF BATHTUBS
If the bathtub has been used for more than 20 years, it may be more rational to use epoxy for restoration. Unlike acrylic, compounds based on epoxy, hardener, filler, and fiberglass cloth can reinforce an old hull, patch a drain hole, and even repair pitting. It is clear that the patches are placed on the bathtub from the outer surface, and the enamel is applied in bulk during restoration.
PREPARATION FOR COATING RESTORATION
Walls for epoxy restoration are prepared more carefully. The main task of preparing for the repair is to achieve a minimum humidity of the body and, at the same time, heat the bath to the operating temperature.

It is impossible to draw hot water into the tub as with acrylic. Cleaning and removing dirt from the walls is carried out similarly to acrylic restoration, with the only difference that neither soda nor cleaning powder can be used. The bathtub must be washed only with liquid products. The second stage is decreasing the enamel with a solvent. It is better to wipe the bath with acetone or P646. Even after the solvent, the tub must be dried and ventilated for a couple more hours before restoration begins.
APPLICATION OF RESIN
Material for enamel restoration is applied in two layers. For the first run, a mixture with reduced viscosity is prepared. At the same time, it is impossible to change the proportions of resin preparation and hardener recommended for restoration. A small amount of acetone is added dropwise to the finished mass for repair. A reasonably liquid polymer is applied to the bath with a brush and rubbed with a plastic scraper. This is a kind of primer. You can not use it if the tub is made of cast iron. For steel cases, priming the bath is mandatory. After the epoxy primer has hardened, it is necessary to inspect the bathtub and carefully cut off all the defects with a blade. The surface is wiped with a solvent.
Then we proceed to the next stage of restoration – good pouring. This time, the resin is not diluted and is even allowed to stand for an hour after mixing with the hardener and filler to increase the viscosity and reduce the flow rate of the repair mass in the bath.

But it would be best if you were careful with the temperature. If it is hot in the room with the bathroom, then it is better to refuse to settle. A day later, you can assemble a drain system on the bath. Wipe the surface of the walls with alcohol and fill the tub with water. The remains of the hardener and resin that did not react during the restoration will pass into the water, after which the liquid is drained, and the bath is rinsed clean with a strong jet.

The restoration process is relatively simple but requires patience and accuracy. If the bathtub has many corrosion points, especially in the bottom part, then restoration by installing an acrylic inner liner would be a more rational solution. A ready-made repair liner in the bath will cost more than a repair kit for restoration. Therefore, it is better to buy with installation to avoid spoiling the acrylic element when installed in the bath. In any case, the restoration of the case will cost much less, and the bathing quality will practically not differ from acrylic.
