    Use this caulk to seal the crawl space liner to the foundation. This premium polyurethane (polymer) caulk is preferred by professional to give the best adhesion when the Foundation Seal Tape™ won't stick due to a wet foundation. This caulk is also used to fill gaps on inside corners, cracks and opening in the foundation as well as sealing the sill plate.

    I ran into concrete block sweating to the point that the foundation tape wouldn't stick. This stuff worked perfectly.

    This caulk is easy to use. I use it at the top of my crawlspace wall plastic sheeting to make a seal above the adhesive strip. It makes a neat job and has never let loose of the sheeting.

    When I first saw the calk it looked like the same stuff you can get at the box stores. (Perhaps some have the same stuff, but when I checked the one by my house didn't.) This is good stuff. Spread it on liberally on a clean surface and it sets up with a good waterproof seal. Then tape the seam with seam tape.

    The Foundation Seal Tape did not hold very well on some of the concrete Foundation blocks. I'm glad I ordered this caulk. It did a great job sticking to the concrete blocks. Even if you can find this at a big box store, it is more expensive than ordering here. Well worth it.
