OR 90WPM is a 100% solids, two-component, spray-applied pure polyurea elastomer engineered for seamless waterproofing. It is used as a protective coating for concrete and steel tanks and clarifiers, foundation and below-grade waterproofing, and buried or protected roof decks — with or without spray foam insulation underneath.
The membrane offers a long open application window, wide temperature tolerance, and excellent abrasion resistance, and can be applied to vertical or horizontal surfaces.
Apply with high-pressure (2,500 PSI class) plural-component proportioning equipment; minimum machine temperature 160°F and 2,200 PSI at a 1:1 ratio. Coverage is approximately 80 sq ft per gallon at 20 mils.
