APPLICATION (cont.)
A ⅜” nap roller is recommended if rolling. Airless spray is
recommended for optimum results. Good results are generally
obtained @ 2,000-3,000 psi at the spray tip.
NOTE: Should a rain event occur in the first 24 hours of
coating application, the product will temporarily turn bronze. It
will return to silver when the rain event passes.
SPRAY EQUIPMENT RECOMMENDATION
Pumps: Graco
®
King 45:1, Graco Bulldog 30:1 or gas
powered equivalents. Graco GH733, HydraMax 350 or GMax
7900 or other manufacturers’ equivalents.
Hose/Pressure: 50’-300’ length (depending on spray rig
pressure). When using hoses longer than 100’, use the next
larger hose ID every 50’. Every 50’ of hose will reduce the
spray pressure of the rig by 10% at the gun tip. i.e. 300’ hose
- ¾” (50’/100’) to ⅝” (50’/100”) to ½” (50’/100’) to ⅜” (50’).
Gun: Graco Contractor Gun, Graco Contractor FTx gun,
Graco Silver Plus or equivalent. (Tip extrusions or pole guns
can be used).

COVERAGE
Over metal, 2 gal./100 square feet. Over corrugated and
irregular metal surfaces, allow for additional surface area by
multiplying length x width by 1.15 minimum.
Over smooth Built-up/Modified Bitumen Roofing, 2½ gal./100
square feet. The surface dictates the actual coverage. The
mounts shown are intended as minimum application
information.
PRODUCT APPLICATION (cont.)
DRY & RECOAT TIMES
Dry and recoat times are based on 70ºF and 50% relative
humidity. Dry times increase at cooler temperatures. Dries to
the touch in 4 hours, weather resistant in 24 hours and full
cure in 10-12 days. Environmental or site specific conditions
may require variations in cure times.
CLEAN-UP
Wash tools and equipment with mineral spirits. Wipe up
splatters before they dry. Follow equipment manufacturer’s
directions to clean spray equipment. Properly dispose of all
soiled rags and containers.
LIMITATIONS
Do not apply when air and surface temperature is below 40°F
or when rain is imminent. Not recommended for use over tar
surfaces, slate, tile, wood, shingles or where water ponds. Do
not apply over newly installed asphalt built-up roofs without
allowing the roof to weather a minimum of 60-90 days.
