Review: Works well on trailer roofs - This is a good product. We have a lot of client's in a vacation park. Their park model trailers take a beating all winter and then get cooked in the sun all summer. This is the best sealant I've found for tpo and rubber roof that trailers have. It is easy to apply and makes a nice solid patch. 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 - Creates a secure, secondary seal along the roof’s edges, air vents, vent pipes and screw heads - Adheres firmly to aluminum, mortar, wood, vinyl, galvanized metal, fiberglass and concrete - Compatible with EPDM and TPO sheeting - Color: White - Item expires 2 years after manufacturer's stamped date - Flash point: 13.0 degrees_celsius ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000BRF7QE | | Best Sellers Rank | #104 in Automotive ( See Top 100 in Automotive ) #1 in RV Sealants | | Brand | Dicor | | Brand Name | Dicor | | Color | White | | Compatible Material | Aluminum, Concrete, Fiberglass, Metal, Vinyl | | Customer Reviews | 4.7 out of 5 stars 18,587 Reviews | | EU Spare Part Availability Duration | 5 Years | | Global Trade Identification Number | 00677917000333 | | Included Components | Tube | | Item Dimensions | 11.25 x 2 x 2 inches | | Item Form | Liquid | | Item Type Name | Dicor 501LSW-1 Lap Sealant - 10.3 oz. | | Item Weight | 12.8 Ounces | | Item dimensions L x W x H | 11.25 x 2 x 2 inches | | Manufacturer | Dicor | | Material | Rubber | | Material Type | Rubber | | Model | 501LSW-1 | | Number of Items | 1 | | Part Number | 501LSW-1 | | Style | Self-Leveling | | Style Name | Self-Leveling | | Surface Recommendation | Roof,Vent | | UPC | 677917000319 700115572927 677917000333 | | Unit Count | 1.0 Count | | Water Resistance Level | Waterproof | ## Product Details - **Brand:** Dicor - **Item Weight:** 12.8 Ounces - **Item dimensions L x W x H:** 11.25 x 2 x 2 inches - **Material:** Rubber - **Style:** Self-Leveling ## Images ![Dicor 501LSW-1 Epdm Self-Leveling Lap Sealant-10.3 Oz.

YOU NEED TO KEEP AIR OUT, what I use is a screw that will fit snug in to the tip hole, then make a aluminum foil cone over that. A small wooden dowel that fits in to the tip hole. Anything that will keep air out **Q: Why does the Amazon photo say it is "self-leveling" but under "Usage" say it is non-leveling? Are products sent labeled the same way?** A: No. There may be an error in the Amazon foto. There are two DIFFERENT Dicor products. Each is labeled self labeling or non leveling on the tube. Self leveling is used for lateral sealing ie. on your roof. Non- leveling is used for verticle sealing ie. where the sides of your RV meet the end cap. I've used it for years and it does a good job. **Q: Will it adhere to the rubber roof material?** A: Yes it will and works perfect for the project. Mine is a rubber roof... **Q: Is the product paintable ?** A: No it is not paintable ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well on trailer roofs *by J***I on April 15, 2026* This is a good product.
