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.
