PRIMER 43 is a professional-grade water-based primer designed to prepare porous and low-cohesion surfaces before the application of waterborne dispersion coatings. Engineered for superior surface preparation, this primer penetrates deeply to consolidate the substrate, enhancing its strength and stability.

Ideal for use on absorbent or weak surfaces, PRIMER 43 acts as an effective adhesion promoter, ensuring optimal bonding and long-lasting performance of subsequent coatings. Whether you’re working on interior or exterior applications, PRIMER 43 improves the durability and efficiency of your coating system—making it an essential step in any professional waterproofing or painting project.
