Adjusting the Color:
Adding small amounts of standard mortar dye achieves custom
coloring. Always transfer material for coloring from the original
container into a clean mixing container when using dye and add the
mortar dye one or two drops at a time. Before adding dye, let product
stand uncovered for about 10 minutes to thicken. After mixing
with a trowel or paddle, drill the product to its needed color.
What are the Coverage Rate(s):
At 1⁄8 inch thickness, 14-18 sq. ft. per gallon. At 1⁄4 inch thickness,
7 - 9 sq. ft. per gallon, depending on texture and porosity of surface
When to Apply:
Surface and air temperature should be a minimum of 45°F and a maximum
of 95°F at the time of application. Do not apply if temperature
is expected to drop below 45°F within a twenty-four hour period.
Do not apply to frozen or frost covered surfaces. Do not apply to
wet or water saturated surfaces and/or when rainfall is expected
within twenty-four hours unless adequate protection with a polyethylene
film, or its equivalent is provided. Do not freeze.
How Long to Wait:
Temperature, humidity, thickness of application and porosity of
the surface to which Chimney RX Trowelable Crown Repair is applied
will affect the curing time of the product. For faster curing in
cool weather, do not mist crown with water before application. In
warmer weather, curing time will be approximately 6 to 8 hours.
In cooler weather, it may take 24 to 72 hours to cure. Protect area
from rain or other moisture source until cured. A plastic covering
may be used for protection if rain fall is expected. If an application
is exposed to a heavy rain before curing, remove any product runoff
with a stiff brush and rinse with water. Thinner films such as 1⁄8
inch will cure faster; thicker applications will cure more slowly
and require longer protection from rain.
