How to apply aluminum roof coatings (airless spray method)
STEP 1: PREPARATION
All surfaces must be clean, have proper drainage and be free
of surface rust, dust and any other foreign matter. For old or
worn surfaces, or surfaces previously coated with aluminum,
apply a prime coat of Gardner or Black Jack fibered asphalt
roof coating. Brush clean all cracks, holes and damaged or
rusted areas with a wire brush. Repair using Universal
Patching Fabric.
DO NOT HEAT OR THIN. DO NOT APPLY IF RAIN IS
EXPECTED WITHIN 36 HOURS.
Mix contents thoroughly. When buying multiple containers,
match the batch codes on the lids to avoid shade variances.
STEP 2: APPLYING ALUMINUM COATING
For exterior use only. Protective clothing and eyewear
should be used during application of this product.
Always apply on a clear, warm sunny day. Apply in
morning hours to allow maximum cure time. Application
should be completed a minimum of 4 hours prior to
sunset. Temperatures must be above 55*F (for 24
hours) and rising, but not above 110°F.
Spray Settings: 1,000-1,500 PSI, .040 to .061 tip size
(depending on spray equipment), 2 gals/minute.
Coverage rates per roofing square:
* Built-up Roofing - 1 1/2 to 2 gallons per square
* Smooth Surfaces or Metal Roofing - 1 to 1 1/2
gallons per square.
Coverage rates may vary depending on texture of
surface.
Notes: Ponding water dulls aluminum and may cause
adhesion failure. Dries to the touch in 4-8 hours and
fully cures in 24-48 hours at 70°F & 50% relative
humidity. Higher humidity, thicker films, poor air flow
and lower temperatures will increase dry times. Night
time moisture or dew during initial curing period will
discolor and dull aluminum finish. This product is not
recommended for use on wood or asphalt shingles.
