Undercoat

A preparatory coating applied beneath the final finish coat on cabinet surfaces. Undercoats include primers, sealers, and wash coats that prepare the wood for the topcoat by sealing pores, blocking stains, and creating a uniform surface for paint or stain adhesion. A properly applied undercoat is essential for achieving a smooth, professional-quality cabinet finish that resists peeling and chipping.
