With a legacy of 50-plus years, Gaco’s GacoFlex LM60 knows how to stand the test of time, having waterproofed millions of square feet of horizontal and vertical surfaces on some of the most sophisticated and aesthetically demanding structures. GacoFlex LM60 is a cold-applied, one-coat, monolithic waterproofing membrane for various surfaces, including underlayment for vegetative roofs. A 100% polyurethane, solvent-free, liquid-applied, two-component coating, GacoFlex LM60 is easy to use — requiring a single application with a squeegee, trowel, spray or brush. Since the LM60 polyurethane waterproof coating is NSF P151 Certified, it is safe for biodiversity and won’t impart contaminants into the water draining from a garden roof.
