Ways of restoration of cast-iron baths

If the bath has traces of rust and smudges that are not washed with a special tool, the gloss disappears and the surface becomes rough, it's time to think about buying a new piece of sanitaryware. But replacing a bath often becomes quite a troublesome exercise. There are often cases when one has to break down a wall in order to pull out old equipment.

Cast-iron bath

If on the surface of the bath began to appear a divorce and yellow coating, it's time to think about its restoration.

A good option in this case may be restoration. Today, the restoration of cast-iron baths is done in three ways. At the same time, the materials used for work guarantee high quality and durability. Some methods are available even to those owners who have a small budget, and if necessary, such work can be performed on their own.

Methods of repair

Enamelled and cast-iron baths are the most common types of sanitary equipment in modern apartments. Some of them have been installed for a long time and are in need of repair. The reason for the wear of enamel coatings can be such factors as the use of abrasive powders or detergents with a chloride base for cleaning baths, as well as the use of chemicals for cleaning water pipes.

To date, the following recovery methods are used:

  • restoration by the imposition of enamel;
  • restoration with liquid acrylic;
  • restoration by installing a special insert.

Enamelling

As a rule, the coating of sanitary equipment with enamel is carried out only in the factory, which is explained by complex technology. First of all, the outer surface of the product is red-hot, then it is sprayed with a small enamel powder and left until it is completely connected to the metal. After that, the bath is again heated to give smoothness and shine to the coating.

Stages of bath enamelling: preparation, degreasing, cleaning

Stages of bath enameling: preparation, degreasing, stripping.

Full enameling of bathtubs can not be performed at home, but during restoration, partial enameling is used, consisting in applying enamel to damaged areas. To restore this way, you will need the following supplies and materials:

  • electric drill with a grinding wheel;
  • sandpaper;
  • abrasive powder;
  • degreaser and rust converter;
  • sprayer and brush with natural bristles;
  • dense napkin;
  • gloves and respirator;
  • enamel with hardener.

In order to restore the cast-iron bath by the enamel method, first of all, it is necessary to thoroughly clean the old surface. The work is done as follows:

  1. The old enamel is sprinkled with abrasive and scraped off using a grinding wheel and sandpaper.
  2. The areas affected by rust are sprinkled with a converter. The bath is aged for 30 minutes, then it is treated with sandpaper.
  3. Dirt and waste crumbs are washed off with water.
  4. A degreaser is applied to the bath. Thus it is desirable to use a dense napkin without a pile.
  5. The bathroom is filled with hot water and warmed up for 10 minutes.
  6. The water is drained, the entire surface is carefully wiped with a dry cloth. On the surface, there should be no pieces of enamel, no dust, no villi.

For the restoration of baths it is desirable to use two-component enamel. It is mixed with hardener according to the manufacturer's instructions and gently mixed. Then a thin layer of enamel is applied to the damaged areas with a brush or spray. The composition should last some time on the surface and dry a little, then another layer is applied.

This completes the restoration of the bath with enamel. Before use, it is advisable to keep the plumbing for 7 days: it is the polymerization of the applied composition that is the most. The service life of the restored equipment will be from 6 to 8 years.

Use of acrylic

Repair of cast-iron baths with acrylic can be attributed to modern methods of restoration, since the material used for this has appeared quite recently.

Acrylic, or stakril, consisting of acrylic and hardener, when applied to the surface creates a strong and smooth film of any desired color.

The remarkable performance of the stakryl made it the most popular material for the restoration work of the baths. First of all, its viscosity is valued, allowing the composition to create solid films on the surface of sanitary equipment with a thickness of 4 to 6 mm. Due to excellent fluidity, acrylic is distributed independently over the surface, evenly enveloping it. Deferred polymerization allows you to work comfortably and accurately, without worrying about that the composition will solidify.

Restore by pouring acrylic

Recovery of the bath with acrylic is done by pouring

After using acrylic, the surface of cast-iron baths is much more durable than enamel and acrylic liner. To carry out the work, it is necessary to prepare the list of materials mentioned above and the acrylic composition. The algorithm of actions does not differ from the works on enamelling, but it is necessary to remove the drain to allow the excess acrylic to drain from the bath.

The process of applying an acrylic layer is as follows:

  • a composition is prepared;
  • the finished mixture slowly poured onto the edge of the bath;
  • as soon as the mixture reaches the day, the acrylic jet should be moved along the perimeter of the bathtub, etc .;
  • When the entire surface is spilled, work should be repeated.

The whole process must be continuous. To achieve this, it is necessary to prepare a container from which it would be convenient to pour out the composition. It is better to mix a little more composition, the smaller: the extra one will still go into the sink in the container under the bathroom.

The polymerization of the acrylic solution usually takes no more than 4 days. It should be borne in mind that the longer the polymerization time, the smoother and smoother the surface will be. The life of such plumbing will be about 20 years.

Restoring the bath with an acrylic insert

Insert installation

Installation liner can be considered the easiest way to restore the plumbing equipment. But before you restore the cast-iron bath, you need to think through your possibilities, because this is not only the most convenient, but also the most expensive method.

For repair, you will need to order the liner in the factory, and then install it yourself in the bath. In order for the process to go right, you must use the following materials:

  • degreaser and abrasive powder for surface cleaning;
  • A special adhesive for gluing the liner to the surface;
  • silicone for sealing joints.

As in previous cases, the bath must be thoroughly cleaned and degreased. Then the dirt is washed off, and the surface is dried. The manufactured acrylic liner is inserted into the bath in such a way that the drain holes coincide completely. Then the edges of the liner are trimmed according to the level of the wall tiles.

The liner is removed, and the surface of the bath is covered with a special adhesive. Then it is applied to the outside of the liner.

The liner and the bath are docked and left for a while to dry. To speed it up, it is necessary to pour cold water into the plumbing equipment and to stand for 24 hours. After the acrylic is firmly attached to the surface of the bath, the joints are smeared with a sealing silicone.

The life of the acrylic liner is about 10 years.

Having familiarized with the above information, everyone can choose the way to restore the bath to your taste and capabilities. The main thing is to remember that today it is quite easy to restore a cast-iron bath. It is not necessary to tolerate unattractive divorces and smudges on the plumbing, which spoil both the impression of its exploitation, and the appearance of the interior.

A very low cost of money and time will make the bathroom perfectly even and aesthetically attractive.
