Stain Blocker is GF's NEW water based white primer. GFSB 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 GF Milk Paints, Chalk Style Paints, & Pigmented Polys.
GF Stain Blocker is designed for effectiveness, not price point. A successful primer requires a sophisticated resin system and an atypical formulation, which will result in a more expensive product. To maximize GFSB's effectiveness, our chemists formulated this product with the highest quality ingredients. Use ONLY for those pieces where you will really care if there is bleed through. GFSB will work every time, not some of the time.
