Stain Blocking Primer
General Finishes has a commitment to water based products and they have been able to formulate a WATER BASED primer that blocks tannins! It can be used to protect painted finishes from stain, dye and wood tannin bleed-through. Brush, roll, or spray over an existing finish, raw wood or MDF as a base coat for light-colored paint. This primer has a sophisticated resin system and an atypical formulation. Use on pieces where you are concerned about bleed-through. White the price point may be steep, the trade off for the no-odor, water based formulation makes it worth it.
Tools can be cleaned with soap and water. Available in quarts.
