    Foundation Seal Tape™ (FST) is used to seal the vapor barrier to the foundation wall. When installed to a completely dry & clean foundation wall, the bond is good enough to hold the vapor barrier to the wall temporarily (several hours/days) until the Foundation Pins are installed. If the foundation wall is wet in the area it will be installed and it will not bond then a polyurethane caulk must be used. This tape is 1.5" x 108' and has a reinforcement inside the tape to eliminate stretching like bubble gum. This is important because without the reinforcement this tape is impossible to apply in a crawl space. Most all other tapes on the market, similar to this one, do not have the reinforcement.

    IMPORTANT-
    Using a wire brush will create dust and debris that fills the pores of the block. When this happens the FST loses most of its grip to the block due to adhering to the dust in the pores rather than the block itself. No matter how much soft brushing you do AFTER the wire brush the FST will likely not stick.
    **During cold month installations this product must be stored indoors prior to use. This product is not meant for installations that have WET or very DAMP foundation walls please use the polyurethane caulk.



    **We always recommend getting a few tubes of Poly Caulk to make sure you have enough material to get a good seal to the foundation and to handle any damp areas on the foundation walls. Remember when you figure your FST to include going under beam pockets, ductwork that is touching the foundation walls and the access door.

    This two sided tape really holds. It sticks like super glue to any surface, i.e., fingers, scissors, etc. But it really held the vapor barrier to the block.

    We painted waterproof paint on the top blocks of our crawl space and the tape stuck just fine to it. It also stuck to the bare concrete block but if there is any dampness or dirt use the caulk. My only trouble with the tape is trying to get the paper off after you stick it to the wall. It holds the onto the plastic but you can do a little repositioning if needed. We used support strips in the corners and CrawlSpace Foundation Pins along the rest of the wall.

    Works great
