Products / Duro-Last Liquid-Applied Flashing

Duro-Last Liquid-Applied Flashing (DL-LAF) is a rapid-setting polymethyl methacrylate (PMMA) liquid-applied flashing for pipes, curbs and other difficult details, usable with all Duro-Last membranes as an alternative to membrane flashings. DL-LAF Field Resin, in summer and winter formulations in 55-lb pails, is catalyzed with DL-LAF Catalyst powder and reinforced with DL-LAF Fleece, a non-woven polyester sold in 13.8-inch by 164-foot rolls; DL-LAF Detailer is a micro-fiber-enhanced grade in 4.4-lb pails for small penetrations where the fleece cannot be applied. The Field Resin data sheet prints a total applied thickness of 97 to 140 mils by substrate profile, white cool-roof values of 0.86 initial solar reflectance and SRI 109 initial and 88 after three years, and properties by ASTM D5147, D5602, D2240, E96 and C1305.
