## Overview

Dicor 501LSW-25 is a premium, HAPS-free self-leveling lap sealant designed for horizontal RV roofing surfaces. This 25-pack of 10.3 oz tubes offers sun-ray stabilized, white-colored sealant that prevents discoloration and adheres to EPDM, TPO, PVC membranes, and various other materials. Ideal for maintenance, repair, and appliance applications, it provides a watertight, flexible seal that withstands road vibrations and weather exposure.

## 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 stop discoloration and decline and will not stain or discolor any material to which it is applied. HAPS-free.

Review: Resealed the roof on a 38 foot motor home. This stuff applied easily and spread out just enough to cover the area needed. More flexible than what the factory put on which should keep the screw heads from working through due to road vibration and body flex. Good price per tube by buying a full case.
Review: Dicor is the go-to for roof RV sealing. I own an RV repair company and we buy this case often! Always dependable. Tubes work great and don’t leak when applying. It levels out just right and for the price you just can’t beat this! Highly recommend!
