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

We found there are too many variations in our stone wall for this to work. We instead used more pins at the top and then used adhesive caulking to seal the top. We only used three feet of this and are not sure what we can use this for, now? Any chance for a return/refund? We bought two rolls of this.

I was very pleased with the quality of materials and the relative ease of installation. You get high marks for quality, service, and an excellent website.
