Ruscoe 5742 Black Lap Sealant

Ruscoe 5742 Black Lap Sealant is a specially formulated high solids, EPDM-based sealant designed to seal the exposed edges of the rubber membrane splice of EPDM roof systems. This sealant has excellent adhesion to clean EPDM surfaces during all adverse weather conditions.

All work surfaces should be clean, dry, free of dirt, dust, debris, oils, un-adhered coatings, deteriorated membrane and other contaminants that may result in a surface that is not sound or is uneven. If necessary, clean the surface to receive the edge sealant with an approved EPDM membrane cleaner.

Store material in original unopened packaging at temperatures between 40°F-110°F. (4°C-38°C). Shelf life is 12 months when stored as recommended.
