Its sun-ray stabilized silicone formula prevents discoloration and spoiling, while providing waterproof, flexible adhesion to a wide range of roofing materials including EPDM, TPO, PVC, metal, wood, and concrete. Packaged in convenient 10.3 oz tubes, it delivers a smooth, professional finish that ensures long-lasting protection and a bright white aesthetic. ## Description Dicor’s Self-Leveling Lap Sealant creates a watertight seal along a roof's edges, air vents, vent pipes, and screw heads. This lap sealant is a versatile sealant formulated for EPDM roofing but also compatible with most other roofing material, including Dicor DiFlex II, Tufflex PVC, and BriTEK TPO roofing. It offers excellent adhesion to aluminum, mortar, wood, vinyl, galvanized metal and concrete. Continuously seals and remains flexible. Color matched, our lap sealants are sun-ray stabilized to avoid discoloration and spoiling and will not stain or discolor any material to which it is applied. HAPS-free. Review: Buy lots! Works great and you’re going to want 2 tubes - Great product and smooths out nice and flat. When they say self levelling they mean it. Don’t try to use on anything vertical. Used with dicor roof repair tape and then redid as many things on the roof that I could with what I had left, wish I had bought a other tube. I’ve heard mixed thoughts on removing old sealant before applying new vs just cover the old stuff. Well my old stuff was in good shape except the expected weather checking and cracks so I just went over the old stuff to maintain water integrity. It went over the old just fine and adhered well so far as I can tell. It smoothed the sealant our like new and removed the water traps. If I had a leak I would probably remove the old sealant and start from new but for touch ups, like I said, buy lots! Review: The Only Lap Sealant I Use! - I have tried a couple of other brands of lap sealant, and the results were simply not good. I recently installed an additional solar panel on my RV. I used a cheaper brand to save a few dollars, huge mistake! So, I decided to order Dicor and used it to finish the project and cover the other brand. The Dicor flows smoothly, it adheres great and the leveling is superb. It makes the project looks so much more professional, and I trust that it will do its job to seal and protect from leaks, etc. No more trying other brands, Dicor is the only lap sealant I will use in the future. ## Features - RV ROOFING USE: Lap sealant is sun-ray stabilized to avoid spoiling and discoloration; Plus, it will not stain or discolor any roofing material to which it is applied - COLOR: Dove bright white hue for stylish and beautiful RV roof - EASY TO USE: Self-leveling for smooth application to RV roofing on horizontal surfaces - SIZE: 10.3 fl. oz. tubes; Pack of 25 - COMPATIBILITY: Works with EPDM, TPO and PVC membranes, it adheres firmly to aluminum, mortar, wood, vinyl, galvanized metal, fiberglass, and concrete ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002UC6T74 | | Best Sellers Rank | #58,443 in Automotive ( See Top 100 in Automotive ) #20 in RV Cleaning, Storage & Maintenance | | Brand | Dicor | | Brand Name | Dicor | | Color | Dove (Bright White) | | Compatible Material | Metal | | Customer Reviews | 4.7 out of 5 stars 734 Reviews | | Global Trade Identification Number | 00677917000296 | | Included Components | Automotive Replacement Parts | | Item Dimensions | 5.1 x 1.5 x 27.9 centimeters | | Item Form | Liquid | | Item Type Name | Rv Maintenance & Repair ( 501Lsd-1 Dicor Self Leveling Lap Sealant - Dove (Brite White)) | | Item Weight | 0.6 Pounds | | Item dimensions L x W x H | 5.1 x 1.5 x 27.9 centimeters | | Item weight | 0.6 Pounds | | Manufacturer | Dicor | | Material | Silicone | | Material Type | Silicone | | Model | 501LSD-1 | | Number of Items | 1 | | Part Interchange Info | 501LSD-1 | | Part Number | 501LSD-1 | | Style | Self-Leveling | | Style Name | Self-Leveling | | Surface Recommendation | Roof | | UPC | 677917000296 677917000364 | | Unit Count | 10.3 Milliliters | | Water Resistance Level | Waterproof | | Water resistance level | Waterproof | ## Product Details - **Brand:** Dicor - **Item dimensions L x W x H:** 5.1 x 1.5 x 27.9 centimeters - **Item weight:** 272 g - **Material:** Silicone - **Style:** Self-Leveling ## Images ![501LSD-1 HAPS-Free Self-Leveling Lap Sealant for horizontal surfaces - 10.3 Oz, Dove (Bright White), Secure, Ideal for RV Roofing, Maintenance, Repair, Appliance Application - Image 1](https://m.media-amazon.com/images/I/71F36C45CVL.jpg) ## Questions & Answers **Q: Can this be used to seal a seam on rubber roofing?** A: Yes you can, Its self leveling so that helps a lot **Q: Can this be used on rubber RV roofs?** A: Yes. I used it last year for a vent replacement and no problems. **Q: What is the difference between white and dove bright white?** A: The Kelvin number indicates the whiteness with 5700 being the most brilliant and 2700 being a warm white. So the range in between indicates the brightness. Check the Kelvin # on the description. **Q: Is there a recommended caulk gun to use with this?** A: No. Any calk gun for that size tube will work. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Buy lots!

It's a great product, but it must be done yearly especially if you store your camper outside. I used it to seal a few cracks, didn't work that great but it was worth a try and it holds up quite well otherwise. ## Frequently Bought Together - Dicor 501LSD-1 HAPS-Free Self-Leveling Lap Sealant for horizontal surfaces - 10.3 Oz, Dove (Bright White), Secure, Ideal for RV Roofing, Maintenance, Repair, Appliance Application - Dicor BT-1834-1 Butyl Seal Tape - 1/8" x 3/4" x 30' Repair Tape for RV, Trailer, Motorhome, Window, and Vent Sealing --- ## 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.ro/products/353356675-501lsd-1-haps-free-self-leveling-lap-sealant-for-horizontal](https://www.desertcart.ro/products/353356675-501lsd-1-haps-free-self-leveling-lap-sealant-for-horizontal) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-08-09*
