Solvent-Based Primer is a high-penetration bonding agent formulated to prepare and seal porous or dusty surfaces before the application of waterproofing membranes, coatings, or adhesives. It is especially effective on concrete, mortar, plaster, and masonry substrates, where it enhances adhesion and prevents delamination of the final coating. Thanks to its solvent-based formulation, it dries quickly and deeply penetrates the surface, making it ideal for outdoor applications and areas exposed to moisture or temperature fluctuations.

This type of primer forms a uniform film that binds surface particles and minimizes the substrate’s absorbency, ensuring optimal performance of subsequent layers like bituminous membranes, paints, or protective coatings. Its fast-drying properties make it ideal for time-sensitive construction and waterproofing tasks. Solvent-Based Primer is an essential component in any professional-grade waterproofing or coating system, ensuring long-lasting protection and durability.
