A base coat applied before paint to help it stick better and cover more evenly.
Primer is a preparatory coating applied to surfaces before the finish paint to promote adhesion, seal porous substrates, provide a uniform base color, and improve the durability of the topcoat. Different primers are formulated for drywall, wood, metal, masonry, and previously painted surfaces. Skipping primer on new drywall causes lap marks and uneven sheen in the finish coat.
The painter applied a PVA drywall primer to all new gypsum board surfaces before the two finish coats to prevent flashing.
