EternaBond RoofSeal Black 4" x50' MicroSealant UV Stable RV Roof Seal Repair Tape | 35 mil Total Thickness - EB-RB040-50R - One-Step Durable, Waterproof and Airtight Sealant

This was very easy to use! I can tell it will work perfectly. Stuck to the roof with a secure snugness. I know this will solve our problem! Just don’t let sticky side touch the same sticky side . It will not release. Exceptional product. Watched an rv YouTuber before purchasing and that sealed the deal for me.

Patched a fiberglass roofs. Very easy to work with., adheres great and made the repair look professional.

Many have used this product to repair tears in their RV rubber roofs, Even on metal. As long as you follow instructions this product is outstanding as far as adhesion and protection for water intrusion. I bought several rolls in 2006 after purchasing a new travel trailer. I bought a quart of acetone to clean the surfaces that I applied the tape. I covered all the perimeter of the travel trailers roof.Generally the rubber is attached via the rain gutter. There are screws every few inches holding the rubber down and the gutter on. Im my mind, these are all potential leak points. As the saying goes, it's not if your RV leaks, but when. I experienced this with a prior RV even after diligent cleaning and caulking of seams. I did all edges and seams on the roof. All roof vents and even used a pieces underneath the crank up antenna.The product has held up outstanding for the 15 years it has been in place. No leaks.Here are some tips/ thoughts about the product and process;Do not over apply the acetone, just wipe the area and let dry.Once you pull the backing off the tape, be careful. The product sticks very very well.Use a J roller to roll the tape down after applying.Once down, you will not get it off easily.My method was to clean the inside of the guttter and the edge of the rubber roof, I applied the product inside the back edge of the gutter, to cover the screws, and then fold over onto the roof. roll it down.I did front and rear seams where metal siding meets rubber roof. I cannot see any of this work from the ground.I cannot think of anything one can do any better to protect roof seams, than using this product. I will do any trailer I may own in the future. It is not inexpensive, but it has done an outstanding job and no seams have loosened, torn, or failed. Very happy with this product.

I bought another brand and then I bought this Everbond brand and this brand is definitely worth every penny!! It’s much thicker and the waterproofing membrane is stickier and makes better contact. It is easy to apply. I suggest to use with the Everbond contact spray as well for a secure bond. It does not remove when contact is made which it a plus!! The pure white backside of the tape even looks better on a white RV roof.I had to repair a large area on top of my roof and went through many steps to make sure water did not get in again. When I applied this Everbond tape as the last step, I realized I could of saved some of the waterproofing steps earlier because of the quality of this tape compared to the tape I bought in the hardware store. This tape stuck and worked so great I was able to cover a gaping crack and hole that was 1”x 6” in my skylight until I can get another skylight ordered. This brand butyl tape is a life saver.

You no doubt purchase this to do a repair, or preventive work on your RV.Many go into a couple of things that may help the novice is never used this before.First of the adhesive qualities are extreme. It will stick to itself and just about anything super easy. It is with caution I described the fact that removing the material if placed in the wrong place can be a daunting task. Therefore it is important that you do not remove the plastic backing except when you are ready to apply it to the specific area. Taking more than a couple of feet at a time, can allow it to bind up on itself. The wider it is the more this is prone to happening. I found it applying the tape and then smoothing it off at an angle was the best way to work when going straight ahead it was often easier to leave bubbles. But applying the material in a straight line but smoothing it off at angle seemed to keep it well in place. It is important to use a roller if at all possible. Even though I only used the 3 inch size, it still required using the roller which really smoothed out the areas. it is usually a little bit easier to apply this material when it's a little bit cooler outside the hotter the RV is, the more tacky the clue is. It may be more flexible when it's warmer but it also sticks a lot more than may be desired. I applied this at about 75° and it was perfect.Pros:It sticks really well to any moderately clean area. It is advised you clean it very well but it sticks great.it is something almost anybody can apply to repair a leak.It is reasonably priced for what it does. It is a little bit pricey but it does do well and allows you to prevent something from occurring or repairing a leak that you have.Cons:The tape loses one star, because the very first foot that you use bonds to itself already. There is no backing of plastic to keep it from doing this so you lose an entire foot before you can apply it. This is not extra they apply to it. You actually lose one full foot of the time you remove all the material. And it bonds to itself very quickly so you lose that put and you're not able to use it. The fact that it cost me a good and this stuff is already expensive as it is. Means that I have to deduct a star. It is a little bit complicated to use if you do not take your time. So allow yourself lots of time because it is not super easy to use. But it is easy enough for the novice to do if they take their time.Overall this material is 10 times better, then FLEXTape, that you see on TV. That stuff is job compared to this. It may be cheaper but it is ill advised to use it. It would not stop any leak after using entire role. However this material here wobbly would stop a pipe leak it so good how it works. But we used it to apply just seems for preventive maintenance. I did not cover the screws or trimming but I cover the gaps that the rail goes on. It has bad butyl tape and being our RVs so long I wanted to put this on their being I cannot remove the trimming myself. Overall I would say purchase this but keep in mind that there's one for missing and because it was taped to itself. That may have just been an error at the factory but nonetheless I lost a foot worth of material that I actually did need at the very and I came up about 6 inches short and had to make adjustments to make it work.

I have not used this kast purchase yet. In the past, this product has held up extremely well & consistency been the best roof sealant material i have used compared to other lower priced brands. Check the thickness of the others for comparisons.
