Premium Vapor Barrier Tape

I used this tape to connect/seal the moisture barrier that I laid under my basement floor. The tape was easy to apply and was very sticky and secure. I like that it was very wide, so it was a bit forgiving on being straight. The tape is very durable and is also moisture proof, which is a requirement for a vapor/moisture barrier installation. The tape is easy to cut with a razor blade or pair of scissors.

I have purchased this product on multiple occasions for crawl space encapsulation. This tape is heavy duty - it’s nice and thick, strong, and bonds great to clean and dry surfaces. I would not hesitate to purchase again.

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.

Great tape. Sticky and does the job. Used it to seal the seams of 13mil vapor barrier in the crawl space. No issues whatsoever, just don’t try to tear or rip it. Bring a utility knife and cut it because it does not rip!

This tape performs as it is intended. It is high quality and looks great when installed. The amount of tack makes it a little difficult to unroll but that makes it stick well when applied. Thanks for the prompt delivery as well.

Even though I had a few areas that the heavy duty tape did not bond well, I still would probably repurchase. I used the tape in a crawlspace encapsulation to re-tape some areas that had previously been taped. Tape is thick and hard for an old lady like me to pull from the roll. I had to use scissors to cut tape.Tape is thick & sticky and did bond in some areas but didn't do well around a column sitting on concrete. No moisture was on the concrete when I tried two times to tape column area, however, tape did not adhere. Price of tape for the quality was good in my opinion.

Tape is wide and pretty strong, adheres well to the vapor barrier on my crawlspace. Shipping was faster than expected. Good value for the money. Tape is thick and seems durable.

Between their vapor barriers and the tape etc, Super durable, worked really well for our crawl space encapsulation. Extremely heavy duty and should hold up well in our crawl space. Especially as we do have hvac and water heater in the area which require easy access and this should hold up! While the cost may seem a bit steep for our purposes it was well worth the money and saved us a lot over having paid someone to do it. Roll is pretty heavy so need to team lift and easiest to cut outside the crawl space to make the job easier
