Consistency: A smooth, heavy trowel consistency which will readily spread on and adhere to vertical and horizontal surfaces without sagging.

Character of Dried Film: Uniform, excellent adhesion to masonry, steel, cured concrete, shingles, asphalt roofing and a variety of other surfaces.

The dried film retains its flexibility and ductility so that the coating will resist extreme variations in temperature and weather.

Has excellent resistance to flow at high temperatures when used on a vertical surface.

SURFACE PREPARATION:
All surfaces should be dry, clean and free from oil or grease, dust, dirt, loose paint or other foreign matter. Recommended application temperature is 40°F to 120°F. If applying at temperatures lower than 40°F, the substrate must be free of moisture and/or ice crystals.

APPLICATION:
Spread 19 Flashing Cement to an average thickness of 1/8” (approximately 8 gallons per square) and press tightly into joints, seams or cracks. To repair large cracks, breaks and blisters:

1. Spread 19 Flashing Cement over the damaged area.

2. Embed 34 Asphalt Saturated Cotton Fabric, 31 Fiberglass Membrane or 5540 Resat-Mat reinforcement.

3. Apply another coat of 19 Flashing Cement over the entire patch.

COVERAGE RATE:
Apply each application at an average thickness of 1/8” (8 gallons per 100 sq. ft.)
