Product Overview
Stain Blocker is General Finishes’s revolutionary water‐based white primer for interior projects. Stain Blocker can be used to protect pigmented finishes from stain, dye and wood tannin bleed‐through. Use over an existing finish, raw wood or MDF as a base coat for light colored General Finishes Milk Paint, Chalk Style Paint and Pigmented Polys. General Finishes Stain Blocker is designed for effectiveness, not price point. A successful primer requires a sophisticated resin system and an atypical formulation. Use on pieces where you are concerned about bleed‐through.
