WHAT IT DOES: Stops roof leaks instantly.
WHAT IS NEEDED TO COMPLETE THE JOB? Trowel, putty knife, gloves and reinforcing fabric.
PREP THE AREA: Surfaces must be clean, free of surface rust and loose material.
HOW TO APPLY: Use trowel to spread across damaged surface of roof. Embed reinforcing fabric after rst layer and apply
second layer on top of fabric.
HOW MUCH DO I NEED? Covers approximately 3 sq. ft. per quart.
DO’s and DON’Ts: Do apply in exterior applications only. Do wear protective clothing. Don’t apply to plastic, EPDM, Hypalon
or similar type of synthetic rubber roof system. If there is a question on compatibility, test a small section rst before applica-
tion to entire surface area.
FOR BEST RESULTS: It is highly recommended to reinforce the repair with a strip of Universal Patching Fabric. Work material
to an even consistency over and into the area to be repaired approximately 1/8” to 1/2” thick, two or three inches beyond the
problem area. Embed fabric into the cement and cover with a second layer of cement. Form a feathered edge with cement
where chimney’s, vent pipes, and other projections meet the roof line. DO NOT EXPOSE DIRECT HEAT/FLAMES OR THIN.
