Review: Sticky stuff on a clean surface - 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.
Review: Durable and Reliable Vapor Barrier Tape for Moisture Protection - I recently purchased the Blue Summit Supplies Vapor Barrier Tape, PE 9mm Polyethylene Tape, for a basement renovation project. This tape has proven to be an excellent choice for sealing moisture barriers and vapor retarders. **Adhesion and Durability** The tape adheres firmly to various surfaces, including polyethylene sheets and concrete walls. It’s incredibly durable, resisting wear and tear, even in high-humidity environments. The adhesive backing ensures a strong bond that remains intact over time. **Ease of Use** Applying the tape is straightforward. It unrolls smoothly, and cutting it to size is hassle-free. The width is perfect for sealing seams, providing ample coverage without being cumbersome. Even for someone new to DIY projects, this tape is user-friendly. **Moisture Protection** This tape effectively prevents moisture from seeping through seams, maintaining a dry environment. It's perfect for basements, crawl spaces, and any area where moisture control is crucial. Since installing it, I've noticed a significant improvement in humidity levels, contributing to a healthier indoor environment. **Value for Money** Considering the tape’s quality and performance, it offers great value for money. Each roll contains plenty of tape, ensuring I have enough for multiple projects. The peace of mind from knowing my home is protected from moisture damage is invaluable. **Conclusion** Overall, I highly recommend the Blue Summit Supplies Vapor Barrier Tape for anyone needing a reliable solution for moisture control. Its strong adhesion, durability, and ease of use make it a must-have for any DIY enthusiast or professional contractor.

### ⭐⭐⭐⭐⭐ Blows duct tape outta the water!
*by R***N on November 22, 2025*

Bought this to seal seems in sheet insulation inside red iron steel building. This stuff will stick to wet glass! I’ve found lots of other uses as well. Sealing plastic sheeting under a pier and beam house and various repairs on anything I don’t want to come loose. Very tenacious holding power and extremely tough.
