Butyl Rubber Waterproof Tape 4” X 50’ (White/Gray) - Weatherproof RV, Roof Window Sealant, Flashing, Seam, Surface Crack, Pipe Rupture, Boat Sealing Review

Wax paper base made the product 10 times easier to work with than other products, it was easy to lay out and apply compared to other products I have used before Application was a breeze . will be my choice for other projects

I bought this tape to make the seams on my RV roof durable but it is very similar to other brands but paper backing is an advantage for me

I have a 25 year old EPDM roof. Some seams came undone. So I bought it based on all the rave reviews. What a great choice! It is very easy to work with him. I had 1.25 inches of rain yesterday and that stopped the leak I was having. I just ordered a second roll to have on hand. Excellent stuff.

This is my first time using this material. It seems to work. I used it as recommended by Grand Design to install a Winegard Cellular/Wi-Fi antenna on the roof of our caravan. This is the first layer between the antenna legs and the roof. Mounting screws are driven through the tape and a self-leveling sealant is then applied over the entire surface. When it works as designed, there are no leaks!

I needed to install a huge patch on the roof of my van that used a lot more tape than I thought it would. It was easy to unroll from the roll; enough paper backing to hold on to while the tape is peeled off. When I didn't get it exactly where I wanted it the first time, I didn't get a second chance without a lump or stretch marks. A windy day made the task difficult. I used caulk to overlap all edges because I didn't trust places where it wouldn't lay flat. This is a good band and I will use it

So I ordered the 'simple' Cofair product first. why anyone would use that instead I have no idea! I thought simple meant white. no, splinters and red! I returned 3 of the 4 rolls I bought because I used some of them. The material is difficult to cut, as it adheres very poorly to scissors, leaving a sticky mass. It is also unsuitable for the weather - it is intended to be passed under something. This rubber band is amazing in comparison. Cuts like clockwork and leaves no marks on the scissors…
