Cetco Bentoseal, 3 Gal

Bentoseal is a trowel-grade bentonite based mastic that is used with Volclay bentonite waterproofing systems to detail at membrane terminations, around penetrations, over grouted concrete form-tie holes, and provide fillets to inside wall corners. Unlike most mastics, this premium mastic is capable of swelling and self-sealing upon hydration and is VOC compliant. Bentoseal can be covered with a waterproofing membrane immediately after application.
