SURFACE
PREPARATION:
All surface preparation should be carried out in accordance
with good painting practices. Remove all loose, peeling or powdery paint from
the surface. All dirt, grease, oil, wax and other foreign material must be removed
with a suitable cleaner and allowed to thoroughly dry. Repair all cracks, holes
and surface imperfections. All smooth or glossy surfaces should be dulled with
sandpaper. New wood surfaces which will be exposed should be coated with a suitable
primer.
APPLICATION:
SAFECOAT EXTERIOR ® Fire Retardant Coating
can be applied by brush, roller or airless spray. Airless equipment is most
desirable. Use Graco Model 490 or larger or other long-stroke piston type units.
Alternatives include gravity fed "Hero" or other diaphragm units.
Use a 16 to 21 thousand aperture, with a 12" fan for optimum results. Apply
uniformly to entire surface. If thinning is required use paint thinner and do
not exceed 250 mL per gallon. Surface and ambient temperature must be maintained
at greater than 35°F (2°C) during application and must remain so for
at least 48 hours following the application. SAFECOAT
EXTERIOR ® / INTERIOR ® is intended for exterior or interior
use. If a higher sheen is desired for aesthetic reasons or to improve scrubbability,
a finish coat of SAFECOAT 725 ® Sealer/Overcoat
is recommended. Please note that the addition of any other finishing coat will
affect the flame spread rating and smoke developed classification. Before applying
any finishing coat consult the manufacturer or their representative. A wet film
thickness gauge can be used at the start of the application to check that sufficient
SAFECOAT EXTERIOR ® has been applied.
At an application rate of 150 sf/USG the wet film thickness should be 10.7 mils
and will yield a dry film thickness of 5.2 mils. The application of SAFECOAT
EXTERIOR ® should be uniform and leave no exposed uncoated surfaces
or edges. If the lumber is pre-coated it should be checked after installation
to ensure that construction procedures have not created any exposed uncoated
areas.
