How and what can paint the cast-iron bath: an overview of the best ways to restore

Each product has its own life, which ends sooner or later. Any thing once fails, and cast iron baths are no exception. Time and water have a negative impact on it and lead to the destruction of the enamel coating. Changing a bath is expensive and time consuming, but there is another option: to restore the product.

There are several ways to paint a cast-iron bath, and all of them are quite accessible.

Advantages of cast iron bath restoration

The enamel coating of the bath becomes thinner over time, rust appears on it due to water, and if you do not take action in time, the process may become irreversible. The bottom can simply rust to holes, and then the bath can no longer be saved.

Bath, covered with rust and limescale, looks, to put it mildly, not aesthetically pleasing. Undoubtedly, to put a new bath would be the only right decision in the event that it is planned to do a major overhaul, to change tiles and plumbing.However, if the repair is still far away, then buying a new bath will bring more problems than joy.

Modern cast-iron baths are not cheap, for the delivery will also have to pay a rather large amount. Due to the large weight of the product, it is unlikely to dismantle the old one and install a new bath. It is necessary either to ask friends and neighbors, or to hire people, which again costs. Most likely, you will have to do repairs, even if it was not planned.

At the same time, the cast-iron bath, having lost its appearance, has not lost its very worthy performance characteristics, and can still serve as faith and truth to its owners. If there are no significant chips and cracks, you can restore the product with your own hands, and quite quickly, without dirt and high costs.

And another significant argument in favor of the restoration: the classic cast-iron baths of the old design are superior in quality to modern counterparts, whose service life does not exceed fifteen years.

Basic ways to update coverage

Today there are three ways to upgrade a cast-iron bath:

  1. Paint the surface with special enamel.
  2. Coating with liquid acrylic.
  3. Insert acrylic liner into the bath.

Each version of the restoration of the old bath has both advantages and disadvantages, which we consider in detail below. To cover the cast iron bath with enamel or acrylic, it is not necessary to be an expert; you can do this work yourself. The main thing - the correct choice of composition and precise adherence to the application technology.

Bath before and after restoration
Restoration of the bath in one of the ways outlined above makes it possible to achieve amazing results and turn an old rusty bath into a practically new product.

Installing the liner of acrylic can also be done by hand, but this work is more delicate and requires certain skills, so in this case it is better to resort to the services of specialists.

Surface preparation before painting

Regardless of the manner in which the cast-iron bath will be painted, the surface must be carefully prepared. This is a very important stage, which can not be missed. Proper surface preparation is 99% success.

Preparation of the bath for painting
The process of preparing the bath consists of several stages. To achieve good and lasting staining, it is necessary to carry them out in a certain sequence.

First of all, the cast-iron bath should be cleaned and degreased. Dirt and grease will prevent adhesion, will not allow the solution to be well absorbed into the surface and will negate all restoration work. In the near future, new enamel can crack and peel off in areas where fat deposits remain.

Acid chemical household chemicals are suitable for cleaning and degreasing. It cleans the oxalic acid bath very effectively (the bath is treated with a solution and left to act for 10-15 minutes).But she is very aggressive, and during work it is necessary to use protective equipment for hands and respiratory organs. Wear rubber gloves and a respirator.

After treatment, rinse the bath well, or even better, fill it with water and hold it for 20 minutes, then let it dry. Now there is an equally important work to do - surface treatment with an abrasive, with which old enamel is removed, and the surface of the bath becomes rough, thereby providing better adhesion of materials.

Abrasive bath treatment
Mechanical surface treatment is carried out using a drill with a special nozzle in the form of a grinding brush, which, when scrolling, removes old enamel and paint from the surface

Rusty bath areas should be cleaned down to the metal, so that in the future it will not pass through a new enamel coating. After stripping and grinding the surface, vacuum the bath to remove dust and small particles from its surface, and then re-treat it with an acid-based liquid detergent.

Pour it into the bath and rub it well over the entire surface, leaving it to last for about an hour and a half.After that, fill the bath to the brim with water and let it stand for about an hour. It is recommended to repeat the washing procedure at least 2-3 times, and then dry the surface with a hair dryer. In order to avoid dye clogging of the siphon, disconnect the bath from the sewer.

If there are chips and cracks on the surface, they must be puttied and then treated with emery paper, after which it is necessary to remove the formed dust again. At this process of preparation is completed, you can proceed to staining.

Bath restoration using enamel

Enameling of the cast-iron bath is an old time-tested method, used for a very long time. But one should distinguish professional enameling, which the bath is subjected to during the production process, and home painting with enamel.

Enamel bath coloring
Painting by enamel is the easiest and most affordable way to update an old cast-iron bath without laborious dismantling

In the first case, professional formulations are used that require pre-heating the cast iron to a certain temperature. In this way, it is impossible and not necessary to paint the cast-iron bath at home.since today there are easy-to-use and inexpensive enamel dyes for self-application.

Advantages and disadvantages of the method

Among the advantages of this method of painting are:

  • low cost;
  • lack of installation work;
  • can be used for cast iron as well as for steel surfaces.

However, there are also disadvantages to this method:

  • the coating is quite thin and fragile, the enamel is very sensitive to household cleaners and shocks. Therefore, the bathroom will have to be treated very carefully in order not to damage it inadvertently;
  • the coating does not allow to eliminate strong defects: chips, dents, cracks;
  • over time, yellowness forms on the surface;
  • Enamel dries long, the bathroom can not be used for about a week.

The service life of the coating is from 5 to 9 years. Although for those who are going to make repairs in the future and change the cast-iron bath to a new one, this period of operation will certainly suit you.

Overview of bath enamels

The question of how to paint the old cast-iron bath is not at all idle, since ordinary enamels in this case are not suitable.It is necessary to use special formulations intended for baths. Before applying any of them, you need to study the instructions and follow the technology exactly, otherwise the coating will not be happy for a long time with its novelty and will quickly peel off.

Bath enamel
It is necessary to work with this enamel very quickly, because after 60 minutes it hardens and becomes unusable.

Among the Russian-made enamels can be distinguished Epoxin 51 and 51C. Enamel consists of two components: epoxy resin and amine hardeners produced in chemical plants in Germany and America. Before using the ingredients are mixed with each other and applied to the surface of the bath. If you wish, you can paint the surface in any color by adding color to the paint.

The structure differs in firmness and at the correct drawing can serve till 9 years. Enamel has a thick texture, which is a certain complexity in the work. In addition, you need to take into account that the use of the prepared solution is no more than an hour, after which the mixture begins to harden and it becomes almost impossible to apply it to the surface.

Bath enamel
The drying time of the enamel solution is about a week, during which you should avoid touching the painted surface

Enamel Finnish production Reafleks 50 has proven itself well. It also consists of two components that are mixed together before application. The price of paint is somewhat more expensive than its domestic counterpart, but the high cost is completely offset by its excellent quality. Enamel forms on the surface of the bath a durable and resistant glossy coating in white or blue.

There are also Russian-made compositions, which, although not as popular as those listed above, have quite decent characteristics. These are enamels Svetlana and Fantasia, which are already ready-made kits, which include, in addition to the enamel and hardener, means for processing the bath.

Bath dyeing kit
The kit includes all the necessary tools for painting the cast-iron bath. The surface dries seven days after dyeing.

Enamel bath coating process

If a two-component formulation is used for dyeing, then before use it must be mixed in the proportion recommended by the manufacturer. But do not mix the whole amount at once. Bath is painted in two layers, so divide the enamel into two parts and first dilute one portion, and after applying the first layer - the second.The duration of the solution is limited, and if you dilute all the paint at once, you may not have time to use it.

Paint brushes for bath
Coloring of the cast-iron bath should be done with a special flat brush - flute. It has a wide natural bristles, which allows you to gently apply the coloring composition on the surface without the formation of stains

Enamels intended for home use, have a rather thick texture, so it is recommended to add to the mixture 646 solvent in a ratio of 10: 1. The first time the walls of the bathroom are painted with one, and the bottom - with two layers.

If smudges form on the surface, they should be immediately removed with a single upward motion of the brush. If you let them dry out, then nothing can be fixed. The second layer is applied 15-20 minutes after the first. During this time, the paint dries, and you will have time to dissolve the second portion of enamel.

The new layer is applied in the same way as the previous one. You can use the bath no earlier than 4-7 days, the exact period specified in the instructions.

Enamel Bath Coating
Coloring is done from top to bottom, first the edges of the bathroom are painted, and then the side surfaces and its bottom

How to care for the restored surface

The cast-iron bath has become as new, but do not forget that enameling the bath at home can not provide such a high-quality and durable coating as originally applied in the production process. Therefore, the new surface must be treated very carefully, because its hardness is much lower than the original.

The bath should be protected from impact and prevent heavy objects from falling; you can not use abrasives to clean it. You can only wash the surface with liquid formulations. It is also not recommended to pour into it too hot water.

Bathtub recovery by liquid acrylic

This method appeared relatively recently, about ten years ago. Today it is very popular and is used by both professional companies and home craftsmen. And it is no coincidence, it is considered the most effective way to restore the cast-iron bath.

Bulk bath acrylic
Bulk acrylic consists of two components: the acrylic itself and the hardener, which are mixed before application. For a standard bath 170 cm long enough 3-4 kg of solution

Advantages and disadvantages of the method

Bulk acrylic is a truly revolutionary tool that can literally in a few hours beyond recognition transform an old cast-iron bath. This method has other advantages:

  • high processing speed with minimal effort. A person who does not have special skills can easily cope with this job;
  • the coating is perfectly even with beautiful glossy shine;
  • when properly applied, the acrylic coating retains its performance and external characteristics for 15 years;
  • acrylic is harmless, does not emit any unpleasant odors and does not require the use of special means of protection;
  • after three days the bath is fully ready for use.

Among the shortcomings, there is only one: a rather high cost compared to enamelling, although the quality and durability of the coating completely compensate for this small minus.

Acrylic coating on the bath

Painting of the cast-iron bath with acrylics is much faster and easier than with enamel. To do this, you will not need any rollers, brushes or other improvised means. Acrylic is simply poured onto the bath, and then under its weight it gradually flows along the walls, forming a smooth and smooth coating.

Application of liquid acrylic
Take a watering can and, starting from the inner corner, move around the entire perimeter of the bath, gradually pouring over the entire top edge

Before starting work, lay a newspaper or cellophane on the floor so as not to stain the floor with acrylics that will drain from the bath. Mix hardener with acrylic enamel. The container in which the hardener was located can be turned into a convenient watering can for applying acrylic, by cutting off its nose at an angle.

The application of acrylic begins with the inner sides of the bath, those that are near the wall. Acrylic has a liquid consistency and quickly flows down. After the upper edge of the bath is completely filled with the solution, start a new circle, but not from the sides, but from the middle of the side walls.

Application of liquid acrylic
After the acrylic stack from the sides of the bath, you need to walk a second time in a circle, pouring in the composition of the non-colored areas

All acrylic flows down, but some places on the bottom and walls of the bath still remain uncoated. To close them, you need to gently level the acrylic with a spatula over all non-poured fragments. The mass, draining, as a rule, rushes to the side of the drain so that it does not clog up, it is necessary to take it to the other side with a spatula. At this time, the acrylic already acquires viscosity and freezes.

Acrylic is applied in a single layer, and on this work on painting the bath is completed. Now your task is to protect the surface from the ingress of particles of dust, debris or water droplets. All this can spoil the coating. Full curing of the acrylic composition occurs within 1.5-2 days.

Restoration with acrylic liner

The essence of the method is to install the liner from acrylic in the old bath. The product is made from sheet acrylic, which is heated to the desired temperature and extruded using a mold. The thickness of the liner is typically 5 mm.

Acrylic liners
Externally, the earbuds resemble an ordinary acrylic bath, but they are not a full-fledged bath and cannot be installed separately.

The insert from acryle has many advantages, main of which is the long service life. With proper operation, it can last up to 20 years. It is very durable, not afraid of mechanical damage and shocks, does not rust and is not covered with yellow bloom. The acrylic insert is easy to clean using conventional household products and does not require the use of aggressive formulations.

After restoration, the cast-iron bath takes on the appearance of a completely new product with a smooth and perfectly smooth glossy surface.Behind the liner, you can hide any damage and defects in the old cast-iron construction.

However, there are many shortcomings in this method. Inserts are made on standard cast-iron baths 1.5 and 1.7 m long, so if it has other dimensions, then this method of restoration will not work. The insert is superimposed on the bath and should encircle it completely. To achieve this, you need to dismantle the bottom row of tiles, as well as remove the siphon equipment.

Acrylic liner
The liner of acrylic in shape and size must fully comply with the bath in which it will be installed; even a slight mismatch in dimensions is not allowed.

Before installing the liner, the bath needs to be prepared, but such thorough preparation as before painting is not required. It is enough to remove the enamel coating with a grinding brush and then degrease the surface with a cleaning agent.

The liner should be tried on, if there are protruding parts, then they will have to be cut with an electric jigsaw. Then mark and cut out the drill hole for overflow and drain. A sealant is applied to the edges of the bath. Installation of the liner is made on a special foam, which evenly covers the entire surface of the bath.

Acrylic Insert Insert
The liner is inserted into the pre-foamed bath and tightly pressed to its bottom and walls

Acrylic insert gently lowered into the container and installed in such a way that there is no distortion. Then the siphon is connected, and the bath is practically filled to the brim with water. In this state, it must be left for a day in order for the foam and sealant to dry completely.

In this way, you can restore the bath yourself, but it is best to turn to the services of companies that perform work at a professional level.
