About this product
SubSeal-40 is a prefabricated self-adhering sheet-type waterproofing membrane. It is composed of a tough multi-layer cross-laminated film that is coated with a rubberized asphalt adhesive. A release liner protects the adhesive and is removed as the membrane is installed. SubSeal-40 is intended as a multi-purpose waterproofing membrane for use in sub-grade applications and under siding, exterior plaster, as a through wall flashing or anywhere it will be protected from long-term ultraviolet exposure. SubSeal-40 adheres aggressively to most clean, dry substrates including metal, wood vinyl, masonry, ICF foundations, Gold Bond e2XP and rigid insulation boards. SubSeal-40 may be used to waterproof foundations and other below grade structures, plaza decks, balconies, under siding, and exterior plaster. This advanced system bonds to the substrate and self seals around nails, staples and other fasteners to prevent damage caused by water penetration.
