Lucas #744 Plastic Cement is a trowel-applied mastic used to install, repair or rebuild roofs at parapet walls, gravel stops, stacks, vents, monitors and similar applications. #744 may be used with fiberglass, polyester fabrics or roll roofing for permanent repairs. If repairing modified bitumen please refer to our #776 Elite Flashing Cement. For repairs to wet or underwater surfaces please refer to our #745 Wet/Dry Plastic Cement or to #776 Elite Flashing Cement.
#744 Plastic Cement is manufactured from Type I asphalt, mineral fillers, petroleum solvents and reinforcing fibers. It applies fast and smooth and breaks cleanly off the trowel without stringing.
The surface to be repaired must be clean, dry and free of debris. Apply #744 Plastic Cement evenly with a pointed roofer's trowel or gloved hand. #744 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.
Shelf Life: 2 years minimum.
