Tannin Bleed-Through Staining Paint — Madrid, Madrid
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.
Waarom dit veel voorkomt in Madrid
Madrid's intense summer UV and dry continental air shorten exterior paint cycles and cause facade cracking, while freeze-thaw stresses render and masonry coatings in winter. Historic-centre facade work requires approved heritage colours and materials, and interior repainting demand is sustained by the large rental market and frequent move-in turnover.
