Undercoat refers to a layer of paint that is applied before the final coat and sometimes after a coat of primer.

The undercoat is an important stage in painting a surface. It not only provides a smoother surface for the topcoat giving it a better finish easier application but can also assist in stopping the surfaces existing colour from bleeding through. The colour of the undercoat should mirror that of the overcoat. For pale and lighter colour use a lighter undercoat and of vide, colourers use a darker undercoat. The undercoat is also important to give the surface some extra protection.

It will help reduce the effects of light physical wear and tear such as denting and scraping as well as giving an extra layer to stop moisture from reaching the surface which can cause mould, rot or in the case of metal rust.
