Product sticks even to damp surfaces, easy to use

I found in my damp crawlspace where my home is built on footings so the barrier had to be put directly on the inside of the bricks. The tape didn't stick to the moist brick. I've had to depend on the pins and caulking to seal the barrier to the interior crawlspace wall. It adhered well to the cement blocks though.

This tape is the real deal. I've referred crawl space repair.com to a local insulation company that does crawl space encapsulating because you guys are the best.

Used foundation seal tape for small crawlspace. Impressed with adhesion to the concrete foundation. It allows for some adjustment of the vapor barrier without it ever pulling from the concrete. Not sure of longevity but stayed put for many days while I added pins. Works as promised.

Worked well and with temps in the 60s, was not too sticky, but bonded well to dry and coated concrete once it was prepped.

Tape would not stick to one wall in this job, as it was wet on the surface and saturated with moisture - however - nothing we tried would stick so its not the fault of the tape. Was able to make it work with a combination of silicone adhesive on the tape to create the seal and a foundation pin every 6". A little overkill, but it worked perfectly. Luckily, this wall was only 5'.

Good stuff - recommended
