About this product
Westcoat’s WP-40 Sheet Membrane is a 40 mil. rubberized asphalt, self-sealing, self-adhering waterproof membrane. It is reinforced with a non-woven polyester fabric. WP-40 has a white polyester scrim which allows light foot traffic and a short period of UV exposure. WP-40 is primarily used on all plywood seams. It is also used as a secondary waterproofing membrane in critical situations or any areas where a self-sealing, self-adhering waterproof membrane is needed.
