White Butyl Tape 1/8 inch x 1 inch x 30 feet for RV/Mobile Home (Single Roll)1

I use this butyl tape in many applications, but the best for me is re-bedding boat stanchions or any hardware that penetrates the deck. I never hardens and that is good if the item needs to be removed. Its flexibility allows it to be molded to conform any shape and it provides a great coverage throughout at the item is tightened. The white color is also desirable for white boat decks. It also works great as a sealer for RV window frames. Overall is a great item to carry in your toolbox for emergency repairs also.

Used in place of the Sprinter roof rail gasket. Initially doubted whether it would be airtight and fill the bolt holes in case of rain. And yes, it passed the test. It's a great option for me.

I am in Florida. By the time I got this is was no longer a round roll but almost triangular. And it would not release from the paper on either side. Not unless I wanted to roll it into a ball. So i keep it in the freezer and cut off strips as I need them. I had to reinstall my taillights and the full width was to wide. I could cut the length needed and then cut the strip in half. But it would get to soft to cut quickly. Within minutes in the southern heat it would be to warm to cut and also starts to stick to paper. Soon after that it got to sticky to work with easily. I bought a used 5th wheel and plan on removing all the exterior lights and scrapping off old stuff, mineral spirits helps clean what doesn't scrape off, and redoing them. Frozen tape is easy to cut to fit and doesn't mold and pushed out excess after tightening it down can be smoothed with a finger (dab in spirits if tape is to sticky).

Overall, this product worked well and I am satisfied with it, and would buy it again. Before this, I used butyl tape from Camping World, which was SUPER cheap, but also a PAIN to remove the butyl tape from its backing.This tape was a million kazillion times easier to get the backing off. It was ever so slightly difficult at times to get the tape backing started, but once I got it started, it came off easily.I have used butyl tape before (I don't know the brand, as it came as part of a kit with another product that required it), but it came off so ridiculously easy I was laughing with joy the entire time.This product is a meaningful compromise. If the camping world tape is a 1, and the other unknown but awesome brand I used was a 10, then THIS one is a solid 8 or even 9. And for the price, I would buy this again for sure.

Butyl tape is not easy to use.I think the reader should understand that it sticks to itself real easily. When it does there is nothing you can do. You just have to cut it out and start again.I used it to seal screws that were passing through a waterproof membrane. It seals the screw hole and it seals the penetration to the membrane.I did not remove the non stick side because in this application you don't need to remove the non stick side. But the reader should realize that when you do remove the non stick side you have no second chances. If you mess up you got to replace the whole thing and start over.The tape I bought did the job it was supposed to do and I'm very satisfied with the product.

I used this for multiple repairs on an Airstream RV. There is a bit of a learning curve when using it and it can still be pain to use but I have much more confidence in the end product being water tight than I would do with silicon and other options. Tips: *try to use when its not too hot or out of direct sun. It stretches and gets harder to work with and separate from the paper*Do not attempt to drill though it. It will grab the bit and pull it out of place. *don't leave leftovers on the ground. it gets everywhere and a pain to dig out of your shoes later.

This stuff is great for preventing or eliminating leaks on boats. DON'T USE SILICONE CAULK, USE BUTYL TAPE! Caulk dries up and cracks, butyl tape stays flexible for decades, literally. I found what I believe to be some original 1971 butyl tape inside a window frame on my sailboat that looked as fresh as the brand new stuff I bought. Also, butyl tape cleans up way easier than caulk.I used it on my sailboat to re-bed windows, lifeline stantions, and deck hardware. For windows you want to go all the way around with the butyl tape (plenty of videos online showing how to do it right). For deck fittings and stantions, just clean the parts and the spot on the boat where they go, put the screws/bolts through the hardware, then put a ring of butyl tape around where the screw/bolt comes through the hardware. Next put it in place, and tighten down. If you start by making the top edge of the hole a little bigger, it will decrease the likelihood of cracks in your gel coat if it flexes under stress.Anyway, I used almost the whole roll working on my boat and bought a second one because no boat should be without it and it stays fresh in a ziplock for years (unlike caulk).Remember, say no to caulk...it will leak, then it'll be a nightmare to clean it up when you finally decide to do it right with butyl tape.

I have a polycarbonate panel roof (40' x 26') that leaks like a sieve. The main reason why it leaks is because the home improvement store strategically placed the wrong size screws next to the panels. These screws are too short so they barely bite into the wood purlins, and the EPDM rubber washers are way too small.Another reason why the roof leaks is due to the capillary action of the water being sucked upwards between the horizontal and vertical overlapped portion of the panels.The leaking is so bad that when I see a screw that's not leaking water I go up to investigate.So I'm replacing all 1400 screws, and putting butyl tape on every overlap. I'm only halfway done, but it's working. I think I'll actually need 24 rolls of this stuff, so if you add in the cost to go with beefier screws, I'm looking at an $800 repair job, not counting my labor.Still, this repair will be cheaper than starting over with metal roofing.
