Blue Summit Supplies Vapor Barrier Tape, 3.78" Wide x 180' Long Roll, Made in USA, PE 9mm Polyethylene Tape, Moisture Barrier Seam for Crawl Space or Marine Use, Waterproof White

Used it on under slab EPS and it worked really well, stayed together even after heavy rains!!

Bought this to bind together sections of water heater insulation blankets that I cut to make insulation blankets for my garage doors. Years ago, I purchased pre-made vinyl covered garage door insulation blankets and they worked great. It appears they are no longer made so I created my own after installing new garage doors. This tape worked perfectly on the vinyl coverings to seam the pieces together. It also bonded well to the garage doors at the edges. For a long lasting bond, I would recommend cleaning the surfaces with alcohol or acetone first and letting it evaporate before applying the tape. Make sure you apply it where you want it the first time as it's difficult to remove. If you accidentally touch the sticky sides together, you better cut another piece as it's nearly impossible to pull the tape back apart without ripping it. Based on how aggressively it sticks to vinyl, I believe it would also be an excellent choice for PE sheet films and vapor barrier. --------------------------- PS - Recently, I reordered this product for another project.. This tape sticks well to most any clean dry surface. Make sure you have it where you want it when applying because it's nearly impossible to reposition once in place. And, when applying a long section of tape, if it touches itself you might as well cut off that section out and start over. You likely won't be able to separate the contact point. Versatile and effective tape for the right projects. Some of the stickiest stuff I've ever used.
