First Prime - Universal Concrete & Masonry Primer (Water-Based)

First Prime™ is a professional-grade, water-based penetrating primer engineered to prepare porous concrete and masonry for overlays, coatings, and sealers. It deeply wets the substrate, locks surface fines, and evens porosity to create a uniform, bond-enhancing foundation.

Designed as the essential first step for decorative and protective systems, First Prime™ improves adhesion, enhances finish uniformity, and extends system performance.
