the tape sticks to concrete with no problems

Are use this tape to stick to the foam board and then attach the guardian liner to I then left it that way for a day came back the next day and a lot of the walls had fallen off! the tape and either pulled off the guardian liner or the foam. I had to go back and re-install and use the Christmas tree fasteners to hold the liner until I finally taped the top edge! It made it easy to install walls just don’t relay on it to hold liner with out a mechanical fasteners!

This is probably the most useful product I used in redoing my crawlspace. It is excellent for hanging the vapor barrier on the crawlspace walls and floor piers. I have used for other applications as well. Extremely useful. The technique shown on the video for unpeeling the craft paper was great advice. Very impressive.

The products I ordered far surpassed the quality offered at the Big Box retailers and were cheaper. Some items weren't even offered, so I was happy to be able to get what I needed to encapsulate my crawlspace myself. Not having to hire someone saved me $1000+. Though it's taking me a bit longer and probably isn't as pretty (there are wrinkles here and there), so long as it functions as needed and I needn't worry about low quality materials, I'm ecstatic!! Definitely recommend this company and its' products to those wanted high-quality materials. This from a DIY-er layman.
