Eternabond BWG features a durable and UV resistant polyethylene face which is laminated to a patented micro-sealant backing with ’quick release’ silicone liner. Waterproofing tape is activated under pressure and primes the construction or building substrate. Etermabond instantly bonds to that surface to form a waterproof and airtight seal.
