LATICRETE® Primer Plus

Primer Plus is a premium, concentrated multi-purpose primer designed to boost the bond and performance of NXT® and SUPERCAP® self-leveling underlayments and FRACTURE BAN® peel-and-stick membranes. Formulated with nano-particles, it penetrates deep into concrete, gypsum, plywood, OSB, terrazzo, tile, and other approved substrates to reduce suction and prevent premature moisture loss from SLUs. This water-based primer enhances adhesion, helps create a more consistent, durable surface, and is easy to apply by broom, roller, or sprayer. Ideal for interior commercial and residential projects where reliable, long-lasting underlayment performance is critical.
