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.


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.


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.
