Mapei Silancolor Primer

Siloxane-Based Breathable Primer for Interior and Exterior Masonry

Mapei Silancolor Primer is a water-based, solvent-free siloxane primer designed to regulate substrate absorption and enhance adhesion before applying Silancolor finishes. Its high-penetration formula consolidates surfaces, ensuring uniform application of topcoats while maintaining breathability. Ideal for both interior and exterior use, it is suitable for environments with limited ventilation.
