#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.
