OR 80SLM "Silver Lining Membrane" is a 100% solids, two-component, spray-applied pure polyurea elastomer — the ultimate maximum-longevity roof and waterproofing system. Tested and certified at Miami-Dade airport for extreme wind uplift, independently validated to ASTM D6083, and rated UL 2218 Class 4 for hail impact resistance.
It is a tough, rapid-set, high-build coating that is VOC compliant and moisture tolerant, with superior reflective qualities. Typical uses include protective coating for metal and built-up roofs, coating over urethane and EPS insulation, wearing and waterproofing membranes for pedestrian decks, and external containment liners (approved for food-grade dry bulk goods).
Apply with high-pressure plural-component equipment (minimum 160°F machine temperature, 2,200 PSI) at a 1:1 ratio. Coverage is approximately 80 sq ft per gallon at 20 mils; tack free in 10–20 seconds and back in service in about an hour.
