Pricing is for a single tube.

Inspect your roof yearly and keep it new with Dicor colour matched sealant.
Helps create a watertight seal along a roof’s edges, air vents, vent pipes and screw heads. Dicor Products Lap Sealant is a versatile sealant formulated for EPDM roofing but also compatible with most other roofing material. It offers excellent adhesion to aluminum, mortar, wood, vinyl, galvanized metal and concrete. Continuously seals and remains flexible. Color matched, our lap sealants are UV stabilized to prevent discolouration and deterioration and will not stain or discolor any material to which it is applied.

    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.
