Tannin Bleed-Through Staining Paint — San Francisco, California
Yellow or brown stains appear through freshly painted surfaces, especially over knots in wood, cedar, or redwood siding. Tannins are natural chemicals in wood that dissolve in moisture and migrate through standard latex paint. A professional painter can properly sand, apply a stain-blocking shellac or oil-based primer, and repaint the surface so the discoloration does not return.
