This plastic is the highest of quality . I used the twenty mil with 42 and it has made a world of difference. I highly recommend this product and company.

Easy to work with. Sticks well when vapor barrier is clean.

This seam tape was easy to use and allowed us to seal the seams in the liner very well. Also good for sealing penetrations. Buy plenty!

When it sticks, it stays! Be mindful that you put it where you want it because it is very difficult to remove.

Worked as described.
