The Power of General Finishes Wood Primer Stain Blocker

From the test lab at GF University: See the power of General Finishes' stain blocking primer, Stain Blocker, over red dye stain - a notoriously difficult color to cover.

PRODUCTS FEATURED:

We tested 2 coats General Finishes Stain Blocker against 2 coats from leading water-based primer competitors to show which primer stops bleed-through best. Stain Blocker acts as a chemical barrier that adheres well to prepped interior raw wood and previous existing finishes. It can be used to protect pigmented finishes from stain, dye and wood tannin bleed-through.
