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.

Application:

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.
