Application
Polycoat Staingard™ 9072SC can be applied by phenolic resin
core roller, high pressure spray, or through a cup gun under
low pressure. Polycoat-Staingard 9072SC should be applied at
a minimum film thickness of 5 mils. It should be noted that the
heavier the application, the longer the curing process takes.
Apply Polycoat Staingard™ 9072SC evenly over the entire
deck. For best results, use an airless sprayer. A phenolic resin
core roller may be used, but extra care should be taken not
to cause air bubbles.
Curing
At 75°F (24°C) and 50% relative humidity, allow each coat to
cure 2-4 hours.
Allow 6 hours before permitting light pedestrian traffic and at
least 24-48 hours before permitting heavy pedestrian traffic
on to the finished surface.
Uncured Polycoat Staingard™ 9072SC is very sensitive to
heat and moisture. Higher temperatures and/or high humidity
will accelerate the cure time. Use caution in batch sizes and
thickness of application. If more than 12 hours have passed
after applying clear coat of Polyaspartic, then re-prime surface
with Polyprime U and apply Polycoat Staingard™ pigmented
®
coat. If clear coat is required, then clear coat should be applied
only after pigmented coat. If clear coat is applied after primer,
the primer will become yellowish with exposure to light and
surface will not look aesthetically pleasing.
Low temperature and/or low humidity extend the cure time.
Cleanup
Equipment should be cleaned with an environmentally safe
