General Finishes Stain Blocking Primer
Best stain-blocking base for furniture painters tackling tannin-prone wood surfaces.
This water-based primer is the ultimate insurance policy against stubborn wood tannins and bleed-through. While it requires a bit more patience than a standard primer, its unique resin system creates an impenetrable barrier that keeps light-colored finishes looking crisp and clean, even on the most temperamental surfaces.
