2. Cement paints.
In cement paints, the binder is white or colored Portland cement, so alkali-resistant pigments are used. To increase the water-holding capacity, up to 15% slaked lime and calcium chloride are added to the cement paint. To increase weather resistance, 1% of water-repellent substances (calcium stearate) are added. Cement paints are water-resistant, so they are used for external painting and internal painting of damp industrial premises on concrete, brick, and plaster. After romania mobile database to the surface, cement paints are moistened for some time.
3. Silicate paints.
Silicate paints are a suspension of alkali-resistant pigments and fillers (mainly in the form of separated chalk and talc). Dry zinc white or calcium borate are used as silicatizers. Liquid potassium glass is also added. Ocher and metallic red lead are used as alkali-resistant pigments. Crushed quartz sand, diatomite or tripoli are added as active siliceous filler.
Brand A includes silicate paints containing zinc white in the dry pigment part. Brand B includes silicate paints containing calcium borate in their composition. Silicate paints are supplied in two-component packaging - separately dry part and liquid potassium glass. Before use, liquid glass and dry part are mixed in a ratio of 2:1 by weight. Silicate paints are water-soluble, non-toxic, allow to obtain vapor-permeable and relatively resistant to water and temperature changes coatings. Also, silicate paints are characterized by low hydrophobicity. Silicate paints are used for decorating facades and interiors (when working on stone, concrete, plaster) and also for protecting wooden structures from fire. Silicate paint applied to a base containing free calcium hydroxide (cement or cement-lime plaster) increases the weather resistance of the outer coating.
