Dupont Flashing Tape - 4-inch x 75-feet Roll - 1 Roll (D15147389) - Enhanced SEO Review

As a person who uses a lot of tools and home improvement products, I was excited to try this flashing tape. However, as a result of my tests, I determined that it has a very poor adhesive quality. I had to go over the same place several times for it to stick, and even then, it was still coming off days later. The only good thing I could say about it is that the roll pack is compact and easy to carry around. Overall, I wouldn't recommend it as it was a complete waste of money.

Happy with the purchase and the quality of this flashing strap. I've used other brands in the past that had sticking issues. People then suggest using 3M spray adhesive to improve adhesion. I don't need multiple steps to apply flashing tape. I'm happy with how it works and I have no doubt that it will hold up and do its intended job. Would definitely buy again for future installs.

This is from a professional contractor who uses waterproof tape all the time. It's a pretty good band. Better than most, but nowhere near as good as a rolled zipper. I used this in a quick rebuild with homemade Tyvek sheeting so I decided to try it on the full system it was designed for. It took about 5 weeks to install while waiting for siding and some gaps formed between the butyl and tyvek. Like I said, decent, but I'm sticking with the full liquid zip system used for my larger work.
