What is paint?
PAINT IS MADE UP OF FOUR ELEMENTS:
Pigment is finely ground, undissolvable powder that provides the color of paint. There are two kinds of pigments:
Prime Pigments – These provide the primary color of the paint. Typically, the higher the quality of the paint, the more prime pigments. These pigments affect the scrubbability and the coverage of the paint.
Extender Pigments – These are made up of clay, silica, talc or chalk. They are less expensive and typically do not perform as well as prime pigments when it comes to covering imperfections.
Binders are made up of acrylics, polyurethanes, polyesters, resins, epoxy and oil. The binder is the film component of the paint that controls how the paint adheres to the wall and cures/dries. As the liquid in the paint evaporates, the binder creates a solid film on the top layer of the paint.
Liquids regulate the viscosity (thickness) of the paint. The lower the viscosity, the easier the paint spreads on the wall. While more surface coverage may sound great, it’s important to note that low viscosity paint is very thin and requires two or more coats to provide an even, balanced coverage to ensure any imperfections on your walls are hidden.
Additives improve the flow, finish, and sometimes even provide UV sun fading protection and fight bacterial growth. The more additives, the higher the quality of the paint… and typically the higher the price.
