SURFACE PREPARATIONS: All surfaces should be clean, dry and free from oil, grease, dust, dirt, loose
paint or other foreign matter. Excess water should be removed, if possible, before application of 19 Ultra.
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.

(approximately 8 gallons per square) and press tightly into joints, seams or cracks.
To repair large cracks, breaks and blisters:
1. Spread 19 Ultra Rubberized Flashing Cement over the damaged area.
2. Embed 34 Asphalt Saturated Cotton Fabric, 31 Fiberglass Membrane or 5540 Resat-Mat
reinforcement.

roofing, skylight flashings and a variety of other surfaces.
Film Performance Characteristics: The dried film retains its flexibility and ductility so that the
coating will resist extreme variations in temperature and weather.
Sag Resistance: Excellent resistance to flow at high roof temperatures on vertical surfaces.
Homogenized: Thoroughly mixed and consistent throughout.
