RLA Non Porous Primer – Water-Based Primer

RLA Non Porous Primer is a fast-drying, water-based primer formulated to promote adhesion of RLA waterproof membranes and tile adhesives over difficult-to-bond substrates. It provides a safe, effective alternative to solvent etch primers and eliminates the need for mechanical grinding or acid etching.

Designed for internal and external applications, RLA Non Porous Primer creates a high-adhesion surface film that bonds reliably to metals, tiles, plastics, and dense concrete. Once dry, it forms a thin, durable coating that enhances the performance and longevity of the applied membrane or adhesive system.

This primer is ideal for renovation or remedial projects where existing non-porous surfaces need preparation prior to waterproofing or tiling.
