Products / Duro-Last Liquid-Applied Flashing Primer

Duro-Last Liquid-Applied Flashing (DL-LAF) Primer is a rapid-setting proprietary polymethyl methacrylate (PMMA) primer used to promote adhesion of DL-LAF flashing over concrete, masonry and wood substrates. It is catalyzed with DL-LAF Catalyst powder at 2 to 6 percent depending on temperature and is sold in 22-lb (2.5-gallon) pails. The data sheet prints coverage of 0.082 to 0.17 lb per square foot, 15 to 30 mils thick, for smooth to rough concrete surface profiles, and reports viscosity by ASTM D562 and hardness by ASTM D2240.
