Paint has four major components: pigments, binders, solvents, and additives. Pigments serve to give paint its color, texture, toughness, as well as determining if a paint is opaque or not. Common white pigments include titanium dioxide and zinc oxide. Binders are the film forming component of a paint as it dries and affects the durability ...
In this case, a texture paint is generally applied with a spray gun. The texture is then painted over with the appropriate color. When painting walls, orange peel can also develop by using a roller with too little paint or too thick a paint and the surface dries before the texture can level.
Roof coatings can add 25 years to the service life of a roof and reduce the amount of discarded roofing materials that end up in landfills. The infrared image on the right shows 79 °C (174 °F) on the uncoated (black) section of the modified bitumen roof. The coated (white) section is 26 °C (79 °F).
Pozzolanic materials are occasionally added to give a much harder wearing paint finish. This addition creates a short open time and therefore requires timely application of the altered paint. Linseed oil is sometimes added (typically 0.5-2%) to improve adhesion on difficult surfaces. Cement addition makes a harder wearing paint in white or grey ...

The sheen [4] or gloss level of a paint is principally determined by the ratio of resinous, adhesive binder, which solidifies after drying, and solid, powdery pigment.The more binder the coating contains, the more regular reflection will be made from its smooth surface; conversely, with less binder, grains of pigment become exposed to the surface, scattering the light and providing matte ...
Pigment – this is the part of the paint that is seen by the eye. The pigment gives the paint opacity and color. The pigments of all paints contain a white base composed of titanium dioxide (TiO 2) or zinc oxide (ZnO). Dyes are added to the pigment to attain the desired color. Binder – the binder is the glue that holds the paint together ...
Silicate paints are incombustible and free of organic additives or solvents (DIN 18363 Painting and coating work Section 2.4.1). Silicate paints are highly color-tone stable. As they are solely colored with mineral pigments that do not fade with exposure to UV radiation, the silicate paint coats remain constant in color for decades.
