Stain Blocker is General Finishes’ 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.

Must be used before Brushable White Enamel.
