Stain Blocker is General Finishes's revolutionary water-based white primer for interior projects.

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.

Stain Blocker is a water-based primer specially formulated to stop extreme tannins and stains from bleeding through paint and causing discoloration.  For DIY customers or professionals painting a surface any shade of white or light gray, look no further than Stain Blocker.
