Stain-Blocking Primer SealerThis premium solvent-based, high-performance stain-blocking primer sealer is formulated with modified alkyd resin to deliver a smooth, flat matt finish. Suitable for both interior and exterior applications, it provides exceptional adhesion and sealing power across a wide range of surfaces—including previously painted substrates, cured plaster and cement coatings, concrete, brick, metals, wood, and rigid PVC. Engineered to tackle even the most challenging stains, it effectively blocks nicotine, water marks, smoke damage, graffiti, and tannin bleed, creating a clean, stable surface ready for painting. Its versatile formulation can be over-coated with either water-based or solvent-based topcoats, making it an ideal problem-solving primer for demanding renovation and refurbishment projects.
