In essence, exterior house paint contains four ingredients: pigments, solvents, additives, and binders. Each ingredient has a distinct function, which helps the paint to adhere to the surface, maintain its color over time, and resist mildew or other problems down the line. Different types of paint have different proportions of these four components. In general, though, most paints have essentially this same constitution. Reputable Colorado Springs painting contractors can point out the differences in the ingredients of various kinds of paint.

Pigments are the components that are most associated with paint. These are the ingredients that give each paint its particular color. Depending on the particular paint, the pigments may be made of natural or man made materials. For example, some minerals remain in use for house paints in powdered form, including clay, silica, carbon black, and iron oxide. Pigments have a tendency to separate from the other ingredients in paint. For this reason, mechanical paint shakers are typically used when paint is sold.

Solvents are liquids that evaporate quickly. As long as the solvents remain in a solution, they keep the binders and the pigments in liquid suspension. When the paint begins to dry, it is because the solvents are evaporating. In water based paint, water is the primary solvent. However, in addition to water, other solvents are often used to paint to ensure a desirable consistency.

Additives include a whole host of chemical and other components. These additives vary widely, but generally they serve to make the paint easier to use and better suited to any specific purposes. For example, most outdoor paints contain some additives intended to resist mildew issues. Other additives can make the paint easier to spread across the walls. Some additives change the length of time that the paint requires to dry. Most paint contains additives to reduce brush drag.

Binders serve to hold the paint together once it dries. After all, paint is unique in that it remains a liquid when in the can, but when spread in a thin layer over the wall, it becomes a solid film. These binders may be oil based or latex based, with the latter more widespread for house paints.

For those who have ever wondered why two paint cans have such different price tags, one reason may be their varied ingredients. While all paints contain some combination of the four above mentioned categories, they can vary widely when it comes down to the specific ingredient list. For the same reason, experienced painters can easily tell the difference between working with one kind of paint and another.
