Bostik Cempolay Universal Primer is a professional-grade, water-based acrylic dispersion primer designed to promote excellent adhesion between substrates and Bostik self-levelling compounds. Ready-mixed for convenience, it can be used undiluted on non-porous surfaces like power-floated concrete, ceramic tiles, or mastic asphalt, and diluted 1:2 with clean water for porous substrates like concrete, screeds, and plywood. It’s fast drying (under 1 hour), low odor, and environmentally conscious—free from harmful solvents. Perfect for use in both domestic and commercial environments, this primer helps prevent surface defects by sealing the substrate and reducing pinholing. Also compatible with warm water underfloor heating systems, Cempolay Universal Primer ensures long-lasting, professional flooring results.
