WRX TRADE - Stain Block - 1 Litre

Stain Block Primer Sealer – High Performance Matt Finish

This solvent-based stain block primer is a premium-quality sealer formulated with modified alkyd resin to deliver exceptional coverage and a smooth matt finish. Designed for both interior and exterior applications, it adheres effectively to a wide variety of surfaces including previously painted areas, fully cured plaster, cement coatings, concrete, brickwork, metal, timber, and rigid PVC.

Engineered to tackle stubborn marks, this high-opacity primer locks in stains such as nicotine, smoke damage, water marks, graffiti, and tannin bleed, preventing them from bleeding through subsequent paint layers. It creates a consistent base by balancing surface porosity and colour, ensuring an even, professional-quality topcoat.
