Review: Great Leak Proof Seal For Your RV - I purchased this 1" Butly Black Tape to create a waterproof seal between the hardware used to mount a Slide Topper to an RV slide. This is some very stick stuff, even in 70 degree weather. It worked great. I applied it to the back of the hardware and carefully stuck it to the mounting spot on the RV. You definately do not need to worry about the part moving while you are screwing it down. A putty knife helped remove the excess that squeezed out on the edges. Followed up with 100% silicone aroung the edges and there you go. I can't imagine any water infiltration would get behind the hardware. I liked that it came packaged in it's own box. I didn't have to mess with crushed or squished tape. The box will definately help store it securely until it's next use. ## Features - APPLICATION: Widely used for window & door waterproof reinforcement, windshield, RV, retrofit, pipe, joint sealing, mobile home, glass, EPDM roof or galvanized metal roofing patching for indoor and outdoor. - WORKING PATTERNS: Suitable to be use on glass, fiberglass, wood, coated or uncoated metals, plastic, rubber at tight corners, unusual curves, uneven and most jagged surfaces; reliably shut off wind, water, dust, oil, grease, vapor, moisture, corrosive chemical and other leakages; paintable feature is making your installation area a seamless, clean, dry and heavy duty water tight workspace. - FEATURES: LLPT Butyl Tape is made of synthetic composited rubber for non-drying, non-hardening and extremely working temperature that provides easy installation, easy forming, quick molding, shock-absorbing, mess free, air tight sealing, waterproof, high viscosity and elasticity. Unlike most butyl seal tape, LLPT Butyl Tape is a premium grade with long life support. - EASY TO USE: : LLPT Sealant Butyl Tape delivers easy molding and instant adhesion to the surface of object; simply clean the surface first for better bonding and release the butyl tape to areas you want to seal with proper press all around the tape; the ideal installation temperature is around 10 Celsius degree, to low will make the tape stiffer which might need a little bit longer time for molding. - WATERPROOFING PERFORMANCE: With LLPT RV rubber butyl tape, you can confidently tackle leaks and protect your vehicle from water damage.

Does it off gas?** A: I used it outside, and did not notice any smell. **Q: good for sealing taillight lens on my camper ?** A: If you're sealing between the lens and the body, yeah, it would work. This is kind of like a tar compound...it is flexible and sticky so kind of think along the lines of pushing some chewing gum in a crack. It's not going to be pretty when the bulb burns out and you have to remove the lens to change it, there's going to be some residue left. but it will seal up the crack for sure. **Q: Is this for RV skylight?** A: It should work great for an RV skylight. I use it to seal windows on boats so you should be fine. **Q: If I apply this in sub-50F degree weather, does adhesion improve when temps go up? I'm using it under a solar panel mounting bracket, with screws.** A: Do you mean below 50F or did you mean minus 50 F? It took me a minute to figure it out. I assume you mean below 50 but not minus 50. Anyway yes to your question if it's below 50 but if it's minus 50 I'm not sure how it would hold up to apply. As in frozen state it might be brittle and getting the film off it might also be difficult. Anyway our temps here in NW MT have surprised us and warmed up above 50 in May nicely and that includes evenings. Often if you are in a warm climate you need to put in the fridge for a day or even freezer for a few hours to help you manage the properties of the butyl caulking. Think of this as a line of caulking in tape form because that's basically what it is. Also some people use two layers and over lap ends when they come together well beyond just a smidge think more like an inch or more overlap. It can spread out a bit. Good luck with your projects and some people like to apply in cooler temps because it can be easier to handle. But way below freezing probably NOT. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Gets the job done. *by K***A on December 25, 2025* Good quality tape used for sealing.

And I've refused to use bad butyl tapes...as they are just not worth the effort to use and often make a big mess. I needed some butyl tape to install a replacement RV roof vent fan and my usual go-to stuff was unavailable, so I decided to give this one a try. I can say this appears to be quality stuff. The roll came shipped in a cardboard box so it wasn't a crushed mess like some others you can order. The initial feel was virtually identical to the stuff I usually use. It is a bit sticky/tacky, but not overly so and pliable, but not overly soft. I squeezed a small piece between my finger and thumb for a minute, then pulled them apart and it did stick and stretched quite nicely...indicating it should provide a good seal at normal temperatures. I ran a couple tests with two small pieces to check how it dealt with temperature changes. One piece was mashed between a folded piece of cling wrap and placed in the freezer (-2F) and another was placed between a folded piece of parchment paper and placed in my toaster oven on warm (160~180F). After 20 minutes in the toaster, I removed the parchment paper and peeled the paper apart. The butyl was just a bit softer than room temperature but it didn't flow/melt and still had good structure. It adhered to the parchment paper and stretched like it should. I (accidentally) left the piece in the freezer for over a day. When I took that one out and tried peeling the cling wrap apart, the butyl again stayed stuck to the film and stretched quite well. This is exactly how a good butyl tape should be...remain pliable and a bit sticky for the whole expected temperature range. The only thing I can't judge right now is if this will remain flexible over time, but it seems like it should. If it does, it will make a very nice and permanent seal. I had no hesitation about using it for my RV fan install project. I will update this review if I find an issue down the road, but I do not expect one at this point. For those that have never used butyl tape, here are a couple hints. Butyl tape is not an adhesive, it is a sealant and requires another means of structural attachment (usually screws). For a good, water-tight seal, apply the tape to the object, then tighten the mechanical fastener (screws) until snug and the butyl is squeezed just a bit. Then let it sit a bit so the butyl flows (ok, not flow but slowly squeezes) and stabilizes. Then go back and tighten a bit more. Repeat this process until the items is secured. You can then use a plastic putty knife to trim away the excess. You can also use a ball of the sealant pressed/tapped against the oozed out sealant to clean up the seams. Just don't pull at it. If you keep the ball of removed sealant clean, you can even reuse it for another project. I recommend warmer temperatures if possible, as it makes this process go more quickly. If done properly, butyl will make a very good, long lasting flexible seal. So, my initial impression is this is a good quality butyl tape and is highly recommended. ## Frequently Bought Together - LLPT Butyl Tape Black 1 Inch x 33Ft Tight Seal for Leak Proof EPDM RV Repair Window Glass Boat Sealing Roof Pipe Patching(BST233) - Dicor 501LSW-1 HAPS-Free Self-Leveling Lap Sealant for horizontal surfaces - 10.3 Oz, White, Secure, Ideal for RV Roofing, Maintenance, Repair, Appliance Application - RecPro 8x1 Pan Head Metal RV Screws | Polar White | Multi-Pack | RV Interior Screws | Factory Finished Looked | (50) --- ## 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.com.cy/products/186460800-llpt-butyl-tape-black-1-inch-x-33ft-2-pack](https://www.desertcart.com.cy/products/186460800-llpt-butyl-tape-black-1-inch-x-33ft-2-pack) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-04-25*
