A paint application is the process of applying a COAT of paint to a surface. It is a common task in many home improvement projects, as well as in industrial and commercial settings. The COAT of paint provides protection from the elements, as well as a decorative finish. The process typically involves preparing the surface, selecting the appropriate type of paint, and then applying the paint with a brush, roller, or sprayer. The COAT of paint must then be allowed to dry before any further work can be done.
