This tape works exactly as advertised. Sticks well to concrete (as long as it is dry) and really sticks to the vapor barrier. I try to line the vapor barrier up carefully over the tape, press in place and then apply a little 'heat' by rubbing a gloved hand over the area. Almost impossible to get the vapor barrier unstuck after that! I also order extra Foundation tape when I want to double seal a seam: foundation tape between the two layers underneath and seam tape over the top of the joint. Works great for peace of mind in wet areas or those hard to reach places where you never want to wedge your body again!

I used this tape to encapsulate the piers in my crawl space. It stuck very well to the cinder block. I used 6 Mil plastic and it adhered perfectly.

This tape stuck to my walls and allowed easy installation of sheeting on the walls.

 

I am very happy with the result since we converted a vented space that was a nightmare into one that was actually pleasant to be in. It should pay in utility bill dividends over the next few years.
