Baths made of cast iron are the most expensive among all types of baths. Their high cost is due to a number of advantages. Cast iron has a wonderful property not to succumb to moisture - it practically does not rust or rot. At the site of the enamel chip, a protective film is formed, and rust does not spread deep into the metal. Its properties in maintaining heat are known to everyone. No wonder the heating batteries are made precisely from cast iron. Products from it, which are constantly in an active and aggressive environment are almost eternal.

Depending on the nature of the damage and the condition of the bath, there are several ways to facing a cast -iron bath. Restoration of enamel using liquid acrylic, applying a new enamel layer at home or installing a plastic tab.
- Emali chips on the side surfaces of a cast -iron bath are easily eliminated with cold welding. It is only required to clean and degrease the damaged surface and fly it as plasticine, but in accordance with the instructions. After hardening cold welding, it lends itself to machining. Grinding, milling or drilling. After grinding, the surface is enamel or decorated with liquid acrylic.
- For individual small cracks or scratches, there are special decorating pencils and polishes of different colors. The scratch is degreased with technical alcohol, if necessary, it is cleaned with sandpaper and decorated according to the instructions for the use of the decorating agent.
Preparation of the processed surface of a cast -iron bath
The preparation of the surface, the method below is necessary when restoring the cast -iron bath by any method.
- First, the surface with a grinding machine or an electric drill with an abrasive nozzle is thoroughly processed. In this case, you can use special finely dispersed grinding powder. It is important not to overdo it and do not do deep depressions. Grinding is carried out in circular movements with light pressure.
- Bringing the entire surface to a perfectly pure state and eliminating all the signs of rust, the dust and remains of abrasive products are washed off with warm and soapy water. The bath is wiped with a soft rag and dried. The entire surface should be processed for better setting with a new coating.
- The surface is degreased, for this you can use technical alcohol or special products and is wiped with a soft bottomless cloth. Try to remove all small villi and dust dust. The container can be treated even with a vacuum cleaner.
Restoration of a cast -iron bathtub by applying enamel
The enamel for the restoration of a cast -iron bath is a two -component drug consisting of epoxy resin and hardener fluid. It can be of different consistency, so decide on the method of surface covering - a brush or a spray.
- Mixing, make according to the instructions on the packaging. It is better to mix a portion for the primary coating to start so that the rest for the second layer of enameling does not thicken until the bathtub will dry.

The first layer of enamel is applied with a brush or spray. Having withstood the time period according to the instructions, apply the second layer. The life of an updated cast -iron bathtub is from 7 to 9 years.
Cast iron bathtub repairs with liquid acrylic
This method appeared relatively recently, thanks to the invention of liquid cold acrylic or stakryla. It is also mixed with a hardener and forms a polymer film on the surface.
- The old cast -iron bath is prepared by the above method. Damaged areas are cleaned, the entire surface of the grinding machine is processed and degreased. Polymezed acrylic creates on the surface of the bath a protective film with a thickness of 4 to 6 mm.
- The process of acrylic coating is somewhat lighter than enamel coating. Pouring, begins from the upper point and by turning and swinging the bathtub distribute it on the surface. Then the fill is made on the opposite side, and the procedure continues until a complete and uniform surface coating with glass. The excess polymer is removed through the drain hole. The service life of such a bath is at least 20 years.
Repair of cast iron bath using a plastic liner
Now they have begun to produce finished plastic bathtub tabs. The most important thing is that such a tab is suitable for size and corresponds to the design of a cast -iron bath.
- The inner surface of the bath is cleaned and degreased in the usual way. Damaged places are treated with a moisture resistant sealant. The acrylic liner is adjusted to the drain and overflowing holes and centered. A two -component mounting foam is applied to the surface of a cast -iron bath.
- The insert is inserted into the bath, and drain nodes are mounted. This must be done promptly, before the foam grabs. After installing the bath, it must be completely filled with water for a more tight pressing of the liner to the base. The perimeter along the side is treated with sealant, to exclude moisture penetration, this is the repair of a cast -iron bath. After 6 - 8 hours, the bath will be ready for operation.
