Stain Blocker is General Finishes' revolutionary water-based stain blocking 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 and Pigmented Polys.
General Finishes Stain Blocker is designed for effectiveness, not price point. This primer has a sophisticated resin system and an atypical formulation. Use on pieces where you are concerned about bleed-through.
Always ensure the surface is clean of contaminants and dust. Sanding any surface too smoothly can reduce adhesion and create application issues like orange peel.
Sand with no finer than 220 grit.
Clean using 50/50 mix of denatured alcohol and water with maroon non-woven pad. Sand with fine (220-320) foam sanding pad or maroon non-woven pad.
