Product Code: L-777-3

Est Delivery between and

Lucas #777 Rubberized Flashing Cement is a premium grade trowel-applied Flashing Cement used to install, repair or rebuild roof flashings at parapet walls, gravel stops, stacks, vents, monitors and similar applications. #777 may be used with polyester fabric reinforcement for permanent repairs to asphalt and modified bitumen roofs. This product is may be applied to wet and underwater surfaces.

#777 Rubberized Flashing Cement is manufactured from refined asphalt, SBS polymers, petroleum solvents, reinforcing fibers and a special water displacing additive. It applies fast and smooth and breaks cleanly off the trowel without stringing.

Application:

The surface to be repaired must be clean and free of debris. Apply #777 Rubberized Flashing Cement evenly with a pointed roofer's trowel or gloved hand. #777 should be applied 1/8 to 1/4 of an inch thick and may be reinforced with polyester fabric to strengthen the repair. When making a permanent repair to a blister, open up the area and allow it to dry thoroughly. In order to adhere to wet surfaces, apply the product in one direction with sufficient force to displace the water from underneath it.

Shelf Life: 2 years minimum.
