## Overview

Dicor 501LSW-1 is a 10.3 oz HAPS-free, self-leveling lap sealant designed for horizontal RV roofing surfaces. It offers superior adhesion to EPDM, TPO, PVC membranes and various materials like aluminum and concrete. Sun-ray stabilized to resist UV damage and discoloration, it creates a watertight, flexible seal that maintains a clean white finish, ensuring long-lasting protection and a professional look.

## 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: 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: Dicor self-leveling caulk is fantastic and very easy to use. I own a 40’ diesel pusher, and it cost me around $200 to redo all the caulking. I probably could have done it for less, but I didn’t want to be stingy with the amount I used. I’m glad I didn’t — now I have peace of mind knowing my roof is sealed up and protected for years to come. The self-leveling feature makes the finish look smooth and professional, even if you’re not an expert. If you’ve been neglecting your RV roof, this product is an absolute must. Well worth the investment! A tip for newbies, cut the tip on an angle but close to the tube (the thick part). You will be laying the caulk on thick and don’t need a fine line as you would with a normal caulking job.

## 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

*by Z***P on 12 February 2023*

私は最初のアプリケーションを途中で通過するまでそれに気づきませんでしたが、注ぎ口がチューブに接続する場所は緩んでいます。それは回転するだけでなく、少しぐらつきます。この製品は、適切に保存されている場合、ほぼ無期限の使用期間を持つことになっています。そして、説明書には「チューブを密封する」と書かれています。しかし、注ぎ口の状態を考えると、これは不可能です。これは輸入品なので、非常に高価なものです。払い戻しの請求をしています。
