I purchased this tape along with a 12mil vapor barrier for a DIY crawl space project. The tape is thick and super sticky so that it adheres quickly and thoroughly to the vapor barrier for a clean, smooth job. The white color blended perfectly with the vapor barrier, to make it seamless. I would highly recommend this product for any vapor barrier project.

This tape is great! The cost does seem high but once you use the product you will realize how tough this stuff is.

Commercial quality, easy to use, would recommend

Great Tape. The last two years I tried to seal leaking joints in the crawl space using different tapes and methods with absolutely no success. This tape really works and does the job. It is worth the money you pay for it. The cleaner the surface the better it works, but even in lightly damp areas I had surprisingly good success.

Tape applied easily per easy instructions with immediate strong adherence. No separation of seams is apparent at close inspection several months later.
