Once I prepped the roof of my horse trailer, I applied this sealing tape. I recommend watching YouTube videos on how to apply. Once I had the right technique it went on easily and feels as though it would never come off. The patented adhesive is amazing as it adheres immediately. Be aware that it doesn't bond to silicone, as stated in the products instructions. My biggest challenge was to get on top of the roof as I get vertigo with heights. Using a ladder that extended beyond the height of the roof, enabled me to easily step onto the roof. Once I did it the first time it was no problem for me with all the up and downs on the ladder. So proud of myself that I repaired my roof all by myself. I read lots of reviews of other products and I believe that EternaBond RoofSeal is the best one to go with. I don't expect that I will have to reseal again, at least not for a very, very, long time. Review: A Must-Have for RV Roof Maintenance - I bought this EternaBond tape as part of some preventative maintenance on my RV roof, and I'm extremely impressed with how well it works. I'd heard good things about it for years, and now I understand why so many RV owners recommend it. The tape is thick, durable, and easy to work with once the surface is properly cleaned. It conforms well to roof seams and creates a strong bond that gives me confidence it will hold up to sun, rain, and long road trips. The 6-inch width provides excellent coverage, making it easy to seal larger areas and seams. I used a seam roller during installation, and the tape adhered incredibly well. Once it's applied, it feels like a permanent repair rather than a temporary patch. The bright white color also blends nicely with the RV roof and looks clean and professional. Considering the cost of water damage repairs, this tape is inexpensive insurance. Whether you're repairing a leak or simply protecting your roof before problems start, it's a product every RV owner should keep on hand. Highly recommended. ## Features - MULTI-USE: Perfect for use on metal buildings, trailer/RV roofs and sides, drain pans, drain pipes, boats, canoes. bonds to a wide range of surfaces including roof materials such as EPDM, TPO, Hypalon, aluminum, galvanized steel, wood, and fiberglass. - NO ADDITIONAL SEALING REQUIRED: Aluminum backing, combined with a layer of advanced MicroSealant, creates a waterproof, moisture, and air tight barrier with no additional sealing required that remains flexible to -57°C (-70°F) - DURABLE SURFACE: Industry leading one step repair system that creates a protective coating for surfaces that require abrasion and corrosion resistance - EXCELLENT UV RESISTANCE: Tape features a durable and UV-stable backing that withstands deterioration in fluctuating temperatures and direct sun exposure - EASY TO USE: Simple and quick one-step repair, using sticky tape with no trays or messy solvents to clean up after the project completion, and no other adhesive needed ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002RSIK4G | | Adhesive Format | Tape | | Adhesive Location | Integrated into the tape | | Adhesive Material | MicroSealant Adhesive Tape | | Adhesive Side Count | 1 | | Best Sellers Rank | #623 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #39 in Adhesive Tapes | | Brand | EternaBond | | Brand Name | EternaBond | | Color | White | | Compatible Material | Alloy Steel, Aluminum, Metal, Wood | | Customer Reviews | 4.8 out of 5 stars 14,256 Reviews | | Foil Thickness | 0.04 inches | | Global Trade Identification Number | 00700115575805, 00891991000533 | | Included Components | Unit^Instruction Guide | | Item Dimensions L x W x Thickness | 600"L x 4"W x 0.04"Th | | Item Resistance | waterproof | | Item Thickness | 0.04 inches | | Item Type Name | EternaBond RSW-4-50 RoofSeal Sealant Tape, White - 4" x 50' | | Item Weight | 3.5 pounds | | Manufacturer | EternaBond | | Material | MicroSealant Adhesive Tape | | Material Type | MicroSealant Adhesive Tape | | Model | RSW-4-50 | | Number of Items | 1 | | Number of Packs | 1 | | Other Special Features of the Product | Durable | | Part Number | RSW-4-50R | | Recommended Uses For Product | Multipurpose | | Size Name | 4" x 50' | | Special Feature | Durable | | Surface Recommendation | Metal | | Tensile Strength | 50 pounds | | UPC | 700115575805 891991000533 | | Unit Count | 50 Feet | | Water Resistance Level | Waterproof | ## Product Details - **Brand:** EternaBond - **Color:** White - **Material:** MicroSealant Adhesive Tape - **Number of Items:** 1 - **Recommended Uses For Product:** Multipurpose ## Images ![EternaBond RoofSeal White 4" x50' MicroSealant UV Stable RV Roof Seal Repair Tape | 35 mil Total Thickness - EB-RW040-50R - One-Step Durable, Waterproof and Airtight Sealant - Image 1](https://m.media-amazon.com/images/I/81x5QLJK+GL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: Can this product be coated/covered with the Liquid Roof EPDM product?** A: My seams on my Motorhome were sealed with this product 10 yrs ago. My roof was recoated with EPDM rubber roof in a bucket three years ago. No problem thus far. **Q: Has anyone used this on galvanized metal roofing? Lots of seams!! Some have been caulked with silicone..** A: I used this sealant on a galvanized camper roof at the numerous seams that were previously coated with silicone. I made sure that I centered the silicone with the sealant. I was worried but took the chance that there would not be a reaction between the two products. it has been two years now and the roof is still fine **Q: What size is the roll of tape** A: The tape is 4 inches wide by 50 feet long. There are three sizes to choose from, 2" x 50' long, 4" x 50' long or 6 inches wide by 50 feet long. It's designated on the packaging as 2-50, 4-50 and 6-50. Works great. You can put it on and done! When you use lap sealants by Dicor or other makers they take up to a month to fully cure. **Q: Would this be good for a large mobile home roof ?** A: I think it would be good to use on any camper or mobile home roof to help stop a leak, especially at a seam, but it would also be a good idea to seal around the edges of the EternaBond with a bead of DiCor sealant. That's what I did on my aluminum camper roof and it worked like a charm. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Strong patented adhesive that bonds immediately *by A***R on August 7, 2026* EternaBond RoofSeal is what you want to get to reseal seams on your metal top RV or trailer.

The roof was covered with snow but looked good from the inside. The first hint of a problem was the first time I washed the trailer. I noticed soap suds and water streaks running down the inside walls. I grabbed my ladder and the problem was evident immediately. The original silicone seam from the manufacturer had developed stress cracks over the course of 10 years. It was a nice wide silicone seal about an 1 1/2 wide and surprisingly thick. The previous owner had tried to reseal some of these areas with clear silicone and in other areas with what appeared to be some sort of epoxy resin. It may have worked for awhile but the end result was a failure. I would have loved to reapply a silicone bead to the seam but there was no way I could match how it came from the factory. I honestly have no idea how they got the bead of silicone to be so uniform and wide. My initial research led me to a product called dicor lap seal. I cleared one side of trailer of silicone with a razor blade initially and a wire brush attached to my drill to clean the rest. I purchased the dicor lap seal specifically because it was self leveling. I was hoping I could apply a wide bead and it would self level enough to approach the width of the original silicone seal. It was apparent after about an hour after the application that it was no where near the width or thickness of the original seal. The lap seal worked well and it was free from leaks on that side of the trailer but I could tell it wasn't going to last that way for long. I needed something wide to bridge the gap between the upright walls of trailer and the roofline. I did some more research and that's when I found this product. I had enough faith in the product after reading some other reviews here and other sites that I removed all the new dicor lap seal with the same process as the silicone removal. I also removed all the other silicone from the trailer roof. I was a little nervous working with a new product that I had such high expectations from. I started with the back of trailer first because it was the shortest side. I started to enroll the tape in about two foot sections and would remove the plastic backer along with it. I applied the tape evenly, first to the top of the upright wall, and the remaining onto the trailer roof. I would press lightly at first to make sure the tape was where I wanted it. I could remove the tape and reapply with great effort if I had to at this time, which I did do several times throughout the entire project. Once I was satisfied with the placement I rolled the tape with the Eternabond 2 pound roller that I had purchased too. This process was quite simple and the bond afterward was impressive to say the least. I tried to pull a section of the tape off after rolling it just to see how well it adhered. The closest example I can think of that you maybe able to relate to is trying to remove a piece of embedded gum from carpet. This stuff sticks end of story! When I got to the end of the roof I took a scissors and cut the tape off evenly. I overlapped the tape on the ends rather than butt them for what I considered a better waterproof seal. It has rained quite a few times with a few thunderstorms in the mix and thus far no leaks whatsoever. The next test will be to see how it fairs over the winter months. I will try to do an update next spring to see if any leaks occur. There is one thing I would have done differently. I should have purchased the 4" wide tape. It wasn't that much more money and it would have given me an extra two inches of waterproof sealing power. I was concerned the 4" tape would be too hard to work with but I would have been fine. I will be keeping this product on hand. I liked working with it that much and I can use it on a variety of things. ## Frequently Bought Together - ETERNABOND RSW450 - Thetford RV Toilet Seal Lube and Conditioner - Toilet Seal Lubricant - 24 oz 36663 - Valterra T58 Twist-On Waste Valve, Mess-Free Waste Valve for RV's, Campers, Trailers --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/1889802-eternabond-roofseal-white-4-x50-microsealant-uv-stable-rv-roof](https://www.desertcart.tn/products/1889802-eternabond-roofseal-white-4-x50-microsealant-uv-stable-rv-roof) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-09*
