So sticky. Only place it once, after that, it’s done.
Holy stickiness. Remember Clark in Christmas Vacation, when the sap stuck to his fingers and the lamp got stuck to him. This is 1000 times worse. Great stuff.

White roof sealant tape
White roof ceiling tape. I used it on many separating siding on my motorhome This tape is very sticky and works really well and looks a lot better than some of the other things offered

Strong. Sticky. Waterproof. Easy to use. Good tape. I like it.
Great repair tape for my camper trailer roof. I had lots of cracks and this tape made the repair job easy. It was good tape for sealing around the skylights and AC unit. The brush on roof coating went right over and made it look great. It's easy to use. Im confident in a dry roof now. 5 thumbs up. See my pictures. I recommend this tape.

Works really well for no traffic applications
The adhesive works well when applied dry, does not do as well if applied to a wet surface. So would say it's highly water resistant but not water proof. Holds up well if applied to a static surface like a wall, or roof. Does not hold up to use in an area with traffic like patching a bathtub floor. It will hold for a while but the adhesive slides and accumulates debris loosing its adhesion moderately quickly even if you're being careful to not step on it much. So if you need a temporary short term fix this will work, but will not hold for a long term. Unsure if it holds up for patching the outside of travel trailers. Have only used for household applications. Does not work as well if stretched, but can be if needed. Not as thick as some other brands but is very good for the price. There is an issue with the adhesive making the edges appear unpleasant after a while as it breaks down. Good size variations.

Solid usability!
Great width - easy to use. I bought it 'in case' the contractor coming to work on the roof didn't have something of equal size and quality. He was more pleased with this tape than what he'd been using in the past! And, I have an extra roll I held back for the future.

Great sealing tape, didn’t last.
The tape worked great, easy to apply but make sure you have a clean surface I used denatured alcohol. Also I used two sizes of rollers one 2” the other 4” to get all the air pockets out. I did check how it held up after a hard rain and was very happy the water was repelled off the tape like it was sprayed with scotch guard! Only problem I had was removing the adhesive covering, it would split at times and stay on the back of the tape at a 45° to a 90° if this happens while your sticking the tape down you have to pull up and remove the tape which is not easy. Forms well when bending to make corners and uneven surfaces. Just to let you know this tape will Not I repeat will not stick to silicone!! So good prep work will save you time and money. All in all a great product I recommend it. I like this tape so much I ordered more for other use’s other then my RV. It’s just a great product! I wish it came in other colors for other applications. “Update this tape only lasted 4 years then it completely fell apart”

I discovered this spring that the roof seams of my RV didn't survive the winter storage all too well, I had several problem areas and one in particular where water was certainly getting through. I researched extensively the options of going with this type of sealing tape vs the lap sealant method. The only real downside of sealing tape in my estimation is that it is essentially permanent, or at least extraordinarily difficult to fully remove. Even that is only a downside if you have to replace the roof membrane or any of the sealed fixtures. In my case, I feel my roof membrane will last at least another 10 years so I decided to seal all the edges of my 36' Class A. I opted not to seal any of the fixtures (vents, skylights etc.) since I may need to replace some of those in the next few years and just touching up the lap sealant in those cases will make that job much easier, but as I replace those items I will certainly tape seal those too. As far as how the product installed, I am impressed so far, I have no experience with the "name brand" product that starts with an E and 3-4x the price to be able to compare the two but this brand appears to be very high quality and I expect it will perform extremely well. I certainly learned some "best practices" along the way I am happy to share: - Do not install this at the peak of a hot and sunny day in direct sunlight, the adhesive becomes too pliable and the backer becomes nearly impossible to remove and the edges will "bleed" and leave a residue on any surface they touch even with the backer still applied. - Temperature is key, a shady spot on a hot day works nicely, keeping the tape pliable enough to mold and stick well but avoiding the problems above. - As others have stated, cut your pieces to length before installing - I found for long runs that placing the pre-cut tape pieces along the edge exactly where you intend to install it (one of my lengths was over 35') and then using pieces of painters tape every 6 feet or so to keep it in place and keep the wind from blowing it off the roof (ask me how I know) - Your "first stick" is critical and must be really well placed to keep a long piece from becoming mis-aligned (there are no do-overs with this stuff so be precise) - After the first stick, peel back really small increments (1-2") at a time, smoothing and rolling as you go and ensuring that your aligment stays correct (this is where the painters tape is a lifesaver). I used a 2.5" rubber roller and a screen door roller and those were helpful. - If you run into mis-aligment problems do not try to remove it, do your best to re-align, install the rest of the piece, and then you can always go back and apply another piece to correct any areas where you got closer to a seam than you wanted, this stuff sticks to everything including itself really well! - Leave the protective side papers on the roll at all times this will keep dust, hair, pollen, bugs, etc. from geting into your edges - It really is quite easy to work with, I'm sure there are lots of ways of getting a good result, but the above steps helped me a ton so good luck!

This product was easy to use and sealed the van rooftop as expected quite effectively. I would recommend this product.

I recently used the WELLUCK RV Sealant Tape to repair a leak in my RV roof, and it worked like a charm! The tape is made of high-quality butyl rubber and polyisobutylene, which makes it incredibly durable and weatherproof. It was easy to apply – just clean the area, cut the tape to size, peel off the backing, and press it down. The tape is UV-resistant and remains flexible even in extreme temperatures, ensuring a long-lasting repair. It effectively sealed the cracks and stopped the leaks without any additional sealing required. Plus, the natural white color blends well with my RV roof and doesn't give a messy look. Overall, this sealant tape has exceeded my expectations in terms of quality and performance. It's a reliable solution for any RV roof repair needs. Highly recommend it!

Colle bien et efficace !

My initial experience with this product is very positive. It seems pretty heavy duty, the adhesive seems strong, and it is easy to work with - just cut the size of the piece, peel off the back, apply and smooth it down. I used it on a sunroom roof patching job, so I'll re- review once it goes through winter, spring and summer!
