trating oil that reaches deep into the crack and forms a complete seal. With the addition
o
f liquid rubber, this flexible, high performance plastic cement provides a superior water-
tight bond that will stop prob
lem leaks for good.

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 first before application to entire
surface area.
FOR BEST RESULTS: It is highly recommended to reinforce the repair with a str
ip of
reinforcing 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 f

yer of cement. Form a feath-
ered edge with cement where chimne
y's, vent pipes, and other projections meet the
roof line. DO NOT EXPOSE DIRECT HEAT/FLAMES OR THIN. Best used when surface
