Sure-Seal Lap Sealant is designed for sealing splice edges of cured Sure-Seal (black) EPDM. Sure-Seal Lap Sealant is a heavy bodied trowel or gun consistency material.
Sure-Seal Lap Sealant is an extremely durable material which dries to the touch in approximately 30 minutes depending on thickness of application and weather conditions. Its cured rubber consistency enables it to expand and contract with the movement of the membrane without cracking or loss of adhesion.
Sure-Seal Lap Sealant may also be used as a sealant in mechanical terminations on vertical or horizontal surfaces, or to seal membranes terminated in reglets in accordance with published details. Sure-Seal Lap Sealant must be applied and feathered on all splice edges by the end of the working day.
