Dicor Self-Leveling Lap Sealant - White

Catalog Item # 32125

Designed for use on horizontal RV roof surfaces, including rubber, TPO, metal, fiberglass, aluminum or wood.

Seals along roof edges, around vent covers, vent pipes, air conditioners and screw heads. Remains flexible. UV-stabilized to prevent deterioration and discoloration. 10.3 oz. tube.

Directions for Use:

Clean surface of all dirt, loose paint, rust, oil and grease. Allow surface to dry before applying sealant. Use standard caulking equipment to apply sealant. In cold weather, warm container at room temperature before use.

Caution:

Keep away from heat, sparks and flame. To avoid breathing vapors, open windows and doors or use other means to insure fresh air entry during application and drying. If you experience eye watering, headaches or dizziness, increase fresh air or wear respiratory protection (NIOSH/MSHA TC23C or equivalent) or leave area. Causes nose, throat, eye and skin irritation.

Spills:

Keep container closed when not in use. In case of spillage, absorb with inert material and dispose of in accordance with applicable regulations.

In Case of Fire:

Use water spray, foam, dry chemical or carbon dioxide. Do not use a solid stream of water because it can scatter and spread the fire. Vapors are heavier than air and may travel along the ground to distant ignition sources and flash back.

First Aid:

If swallowed, do not induce vomiting. Call a physician immediately. If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Glasses or goggles are recommended. In case of eye contact, immediately flush eyes with plenty of water of at least 15 minutes. Chemically resistant gloves recommended. In case of skin contact, thoroughly wash affected area with soap and water.

Health Notice:

Reports have associated repeated and prolonged occupational overexposure to solvents with permanent brain and nervous system damage. Intentional misuse by deliberately concentrating and inhaling the contents may be harmful and fatal.

It is a Dicor product so you should expect it to work right and it does, I have used hundreds of tubes of this product and it al...ways works great. You should be looking at all your sealing spots on your roof at least twice per year to stop the issue of water leaks in your coach also!

I have used this product before and when I needed to install a vent I went back to it. It really works great but you have to put... it on thick. Not to worry, it levels itself to some extent so you don't have to do that. I keep extra tubes just in case I find something that needs resealing.

Dicor Sealant does the job! Easy to apply, and seals cracks and seams around roofing inserts like skylites and vents without erro...r. I had two leads. One in the skylite in the bathroom and one where my TV cable comes in through the roof. Dicor made those leaks history! You won't regret using this product.

Sealant bubbles up

by luke godwin – July 09, 2017

8 out of 16 people found this review helpful.

I used this to seal around two new skylights I installed on my 2014 Prowler RV and the sealant bubbled up along where it connects ...to rubber roof. I did install a bead of the decor non self leveling and set the skylight in the bead of sealant. I then immediately installed the self leveling. The only issues I can think of - maybe too hot - 90 degree day, or some type of reaction to the rubber; There is not really good directions on the sealant to avoid wrong installation so not sure what went wrong but looking for ideas now. Sealant worked fine on the plastic part of the skylight.

Pros: Levels well

See details below. Rubber is bubbling loose from roof.

by Anonymous – May 22, 2015

Applied the sealant yesterday around solar panel brackets, and today I notice the rubber roof material around the brackets is buckling up. The tube directions say there may be surface wrinkle/cosmetic issues. Is this to be expected...? Thanks

Answer the Question

Air bubbles in a rubber roof membrane usually occur after installation of the membrane, but can be caused by weather conditions and humidity, flexing and twisting of the membrane, or even significant difference in temperature between the inside and outside of the unit.

Air bubbles will not effect the performance of your roof and are not to be punctured. The bubbling is likely to go away as the weather changes.

501lsw vs 502lsw sealant

by Mike – January 14, 2013

I have an Open Range 412 residential fifth wheel.The owners manual calls for Dicor 502 lsw. Will the 501lsw you carry do the same job? What is the difference between the two? The unit has a PVC roof does that make a difference?

Answer the Question

Per response from Dicor; "The 501LSW was developed to be used at the consumer level. The 502LSW was developed to be used in a pumping system at the manufacturing level. Very little difference with the exception of case quantity."
