Surface Preparation

Patch test on a small area of roofing membrane before applying to the entire roof surface. Compatible with TPO and other single-ply roofing membranes. It Is recommended to wash the roofing membrane surface prior to application. Roofing membranes should be free of oil, grease, loose material and should be clean and dry. If priming white on a non-white surface, build layers until a solid color is achieved. For the best results, allow the TPO 15C Primer to dry overnight before applying an acrylic topcoat.

Cleanup Information
