## Overview

This flexible sealant ensures a smooth, durable finish that resists discoloration and maintains a watertight barrier around vents and seams.

## 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: Quality product - Works well. Takes a complete tube to do one vent. Apply up the side of the vent a little so you don’t trap water around the vent flashing.
Review: Roof lap sealant - Works great on my recreational vehicle. Make sure and follow the instructions, because it will take a little bit for the sealant to level out to it's final product.

## Questions & Answers

**Q: if i use part of the tube of dicor, how do i keep the tip  from hardening so i can reuse it**
A: YES the Dicor tip has to be sealed.   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
