General Finishes Stain Blocker

Each

Stain Blocker is General Finishes's new water based white primer. It can be used to protect pigmented finishes from stain, dye and wood tannin bleed-through. Use over an existing finish, raw wood, or MDF particle board as a base coat for General Finishes milk paints, chalk style paints and pigmented polys. Apply with a brush or sprayer. Typically used with snow white or antique white milk paint and may not be needed when painting with darker colors. Do not mix with any paint stain or topcoat as contamination from other finishes will cause product failure. Easy cleanup, rinse all brushes and equipment with clean water.
