Enviro Flex FL is a fast curing, high performance, neutral cure, elastomeric polyurethane joint sealant that forms part of Envirosystems waterproofing systems. Enviro Flex FL is designed for use under waterproofing membranes as a cove joint for movement junctions such as floor wall junctions.
Enviro Flex FL can be used for sealing internal corners between building components such as concrete panels, fibre cement sheets, block and brickwork, and around window and door frames prior to membrane application. Enviro Flex FL is suitable for commercial and residential, internal and external applications.
