We used this tape to secure vapor barrier to a poured concrete wall along with christmas tree fasteners. The tape stuck very well to the vapor barrier but was releasing from some sections of the concrete wall during installation. This caused the installation to take much longer than expected.

I was surprised how well it stuck to the cinder block wall. Our crawl space was quite dusty before the liner was applied. It can be unforgiving if you need to pull the liner off the tape in order to smooth out wrinkles as you are moving along the wall. As indicated in the video only apply a small length of liner to the tape at any one time to minimize wrinkling of the liner.

This tape works really well when installing an "attic tent". It holds the tent in place until I can staple it to the framing. It also air seals the opening as well. Longer than necessary for 1 tent, but we install a couple dozen a year. It works great and no mess.

This is a remarkable product. Best 2 sided tape I have ever used. You better put it in the right place the first time because once you put it on the block it it not going to come off.

I wouldn't use this tape on oxidized concrete as the dust wont allow it to seal properly. I would use spray foam if I did it again
