FIELD: chemistry.
SUBSTANCE: invention relates to production of paint materials. The paint composition is prepared by mixing varnish with fine powder of an inorganic material. The powder of inorganic material used is water treatment sludge sieved through a No.0056 sieve, said sludge being formed as a result of removing hardness salts during water treatment at thermal power plants. Components are in the following ratio, wt %: varnish 35-65; said powder of water treatment sludge 35.0-65.0.
EFFECT: method is simple and enables to obtain dough-like and ready-to-use paint compositions.
