CrawlSpace-DIY - Vapor Barrier Tape, 4" x 180' PE 12mm Polyethylene Tape, Moisture Barrier Seal and Seam, Insulation Tape for Crawl Space Vapor Barrier, Marine & More

Product is amazing, it sticks to everything. Heavy duty but still able to tare with your hands for ease of application. The width makes it easy to apply. I couldn't ask for better tape.

This 4" wide vapor barrier tape exceeded my expectations. It sticks extremely well, creating a strong, reliable seal—exactly what you need for moisture control. One of the best features is that while it's tough and holds firm, you can still tear it by hand without needing scissors, which makes installation quick and hassle-free. It also blends in nicely with standard vapor barrier sheeting, giving the whole project a clean, professional look. Highly recommended for anyone working on crawl spaces, basements, or any other vapor barrier setup!

Im involved in a crawI space encapsulation and have reordered this vapor barrier tape. Its tough stuff.You need scissors or a razor knife to cut it, you can't tear this tape.Good and sticky, I've even used it on the concrete block.The 4 inch was probably wider than I need but the cost was the same as others 3 inch tape of the same length.

I used several rolls of this Crawlspace DIY seam tape in my crawl space encapsulation project. This stuff worked extremely well and has a strong affinity to the poly vapor barrier I used. The tape went down well and adhered very well. I used a solid 10 mil vapor barrier so the surface was very smooth making it easier to apply the tape. As with any tape a dust free substrate is desired for the best adhesion. I also smoothed over with a cloth to improve contact with the barrier. This Crawlspace DIY tape is highly recommended. BTW keep some on hand for repairs.

I purchased 3 rolls of the 4" seam tape initially to cover my 2,500 sq foot crawls space seams. The tape is extremely tacky and very forgiving. It will cover over light debris such as dust and dirt but no tape can cover excessive amounts. The 4" seal tape is a great width to use during the sealing of overlaps and seams to guarantee maximum sealing of the joints. The Crawl Space Tap is very durable and fairly easy to work with. The high level of tackiness provides great comfort that an effective seal has occurred. The product worked so well that I just ordered 2 additional rolls to ensure that I have enough to complete my encapsulation product.

It was very sticky and worked great

This is my second purchase. The first roll I purchased was used to put down thick plastic over the first story of our 2 story garage build to protect the second story subflooring during the winter work hiatus. It was very durable and worked great to keep the seams sealed up even with standing water. We are now using the rolls from our second purchase to seal the house wrap and around window installations. The wide tape is much easier to work with than the narrow "Ty***" brand name tape, has great adhesion and is at a better price point. I would definitely purchase yet again.

I used this to adhere to a skirting to my rv for the winter. It worked great, I was able to pull it off to reposition it when installing and it has stayed stuck on very well. You do need to keep the tape from being too cold while installing. I installed on a very cold day and the adhesive wanted to stay on the back of the roll as I unrolled it! I just kept it inside my coat or warmed it with my hands to resolve this issue. I finished installing on a warmer day and didn’t have this issue at all!
