## Overview

Dicor 501LSD-1 is a HAPS-free, self-leveling lap sealant designed for horizontal RV roofing surfaces. Its sun-ray stabilized, bright white silicone formula offers superior adhesion to a wide range of materials including EPDM, TPO, PVC, metal, wood, and concrete. This 10.3 oz tube sealant provides a watertight, flexible, and durable finish that resists discoloration and weather damage, making it a top choice for professional-grade RV maintenance and repair.

## 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!

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.
