The invention discloses paint. The paint comprises the following components according to every one hundred parts by weight: 25-30 parts of white cement, 20-25 parts of titanium dioxide, 18-22 parts of activated chalk, 15 parts of white quartz powder, 2.5-3.5 parts of particulate silicic acid, 1-1.5 parts of calcium chloride, 0.5-1 part of cuprous chloride, 1.5-2.5 parts of diatom powder, 1.5-2.5 parts of bentonite, and 3-4 parts of polyacrylamide. The calcium chloride is food grade calcium chloride. The white cement is in a 325 type. The titanium dioxide is in a rutile type. The paint is safe, environment-friendly, dampproof, anti-condensation, anti-ice, mildew proof, capable of purifying indoor air and adsorbing peculiar smell, low in cost, free of peculiar smell, nonflammable, and capable of being applied to fitment-coating of the inner surfaces of buildings of various industries and houses, wherein the market-set price of solid objects of the paint is 20 yuan / kg, the situations that due to moisture condensation on the surfaces of the buildings, water dripping, water flowing, mould breed and spread, even crack which results in collapse and falling off of a surface layer are caused are avoided, and normal production and living health and safety of people are guaranteed.
