Basic bath restoration operations are usually performed in the following sequence:

  1. How to paint a cast iron bath - painting a cast iron bath Preparation of a two-component composition Before painting the cast-iron bath, pour hot water into it and leave it in this condition for about ten minutes. After this period, drain the water and wipe dry all the internal surfaces of the bath (we note that the surface prepared for the coating must have a matte color and be fairly smooth).
  2. Then you should prepare the working composition used for the restoration of the product, for which you need to mix the previously prepared enamel with hardener. The proportions necessary for mixing are usually indicated on the packaging of the materials used.
  3. Enamel is applied to the surface with a flat brush having a natural bristle; and the coating should be made in two layers. The consumption of material for each of the layers should be distributed approximately equally.
  4. After complete drying of this layer (somewhere in 15-20 minutes upon completion of the operation), the enamel is reapplied.

Experienced masters believe that the entire recovery procedure will not take more than 4 hours from an ordinary user.

This method of renovating the coating is considered to be more reliable than applying enamel using brushes, which, in general, is not always confirmed in practice. Professionals who have to deal closely with this issue, believe that the best option for this is the use of a two-component composition (base plus hardener). But in standard aerosol cans, a hardener is usually absent. To this should be added also the fact that in case of unprofessional handling of the spray gun on the treated surface there may appear smudges and small irregularities.

To obtain a high-quality (that is, even and smooth) layer of enamel coating, in this case, you need a sufficiently powerful compressor. You can certainly try to implement this method of bath restoration on your own, but it will be much safer if you resort to the services of specialists.
