Standard Paint Application Systems
Basic Paint Application Systems
A paint application system is a series of coats of paint, in which each coat performs a specific function. A standard paint application system consists of a primer, undercoat(s), and finishing coat(s). In general, different types of paints will be used for each function, but there are some paint types that can perform more than one function, emulsions for example.
Primer
This is the first coat of paint that is applied to a raw (unpainted) surface.
This is used to “stick” to the substrate and provide adhesion for the remaining coats of paint. It provides a smooth stable surface for the following coats and prevents corrosion and chemical attack of the substrate. There are numerous types of primers that are selected to suit the substrate and surface conditions.
Undercoats
These are applied over the primer coating, or over existing painted surfaces prepared for receiving new paint. They have a low gloss level and a high amount of pigments. They have many functions, increasing the thickness of the overall film, hiding the color of the primer or the previous layer on the existing substrate, and they are generally tinted in a similar color range as the topcoat.
Finishing Coats
As the name suggests, these are the finishing or final coats. They provide the final color and gloss level required. They are the protection layer from weather, moisture, knock and chips. They are the aesthetic layer of the paint system.
