1. CAUTIONS
-
Apply only in a well-ventilated environment with
adequate respiratory protection as prescribed by OSHA
for all latex paints.
-
Do not ingest; induce vomiting if this happens.
-
Avoid contact with eyes; if this happens flush eyes
freely with water until all traces of paint are removed.
-
Avoid prolonged contact with skin; paint can be removed
with warm water & soap.
2. APPLICATION PREPARATION & RECOMMENDED EQUIPMENT
-
VERY IMPORTANT: This product must be
mixed thoroughly before application. We recommend using
a mixing paddle with power drill for a minimum of three
(3) minutes at highest speed. Concentrate on the bottom
of the bucket periodically moving to the middle and top
areas. Product is properly mixed when: (1) there are no
solids attached to the paddle after mixing at the bottom
and (2) the paint shows a uniform consistency when mixed
at the surface.
-
DO NOT dilute or thin this product with
any other liquid.
-
This product may be applied as any other high quality
latex based paint: brush, roller, airless spray - either
gravity feed or suction, or compressed air sprayers.
-
Surfaces must be clean, dry, and free of any grease,
oils or other contaminants. Previous layers of paint
must be solidly adhered to the surface with no flaking,
chipping, or cracks. Bare steel should be primed with
red oxide primer or its equivalent.
-
Spraying is the recommended method of application. The
minimum recommended spray setup is 2500 psi (172 bar)
with a .015 inch tip (.38 mm). All Alsa Corporation test
applications are performed using a Graco XR5 with a .017
inch tip (.43 mm).
-
Optimal application temperature is 85 degrees F (29 C);
do not attempt application below 55 degrees F (13 C).
3. SPECIFIC APPLICATION INSTRUCTIONS
-
Coverage: All coverage rates (except
steel, below) are expressed on a ‘per coat’ basis. A
single coat is applied at a rate of 130 sq feet (12 sqm)
per gallon. This is equivalent to a wet coat of 12 mil
(.30 mm) that will cure to a dry coat 7 mil thick (.18
mm). While under ideal conditions it is possible to
apply a single coat of up to 20-22 mil (.50-.55 mm) wet,
two thin coats are recommended to prevent the
possibility of cracking while curing.
-
Sheetrock (gypsum), OSB (orientated strand
board), plywood, structural lumber, and SIPs (structural
insulated panels): Requires two coats; the
second can be applied when the first is dry to the
touch. Full curing of both coats takes 72 hours.
-
Polyurethane foam insulation (PUF):
Also requires two coats but special consideration needs
to be given to the condition of the foam’s surface prior
to application. Age, type, and method of application
affects the surface porosity of PUF. Field testing has
shown that unless the foam is newly installed and uncut
it can absorb a significant quantity of paint. In these
cases priming with a quality latex primer/sealer such as
Zinnser’s Bullseye 123 is recommended.
-
Structural steel: A final dry film
coating of 70 mil (1.8 mm) is recommended for adequate
protection. Under proper conditions it is possible to
achieve this with 6 coats of 20 mil (.50 mm) wet. Under
less than ideal conditions, it may be necessary to apply
more than 6 coats at a lesser thickness until a total of
120 mil wet (3mm) is achieved. In all cases the next
coat may be applied when the prior is dry to the touch.
-
Top coating is optional. To add color
or sheen to surfaces Alsa Corporation PFB may be top
coated using virtually any alkyd, or enamel paint as
soon as the intumescent coating is dry to the touch. To
top coat with acrylic or latex spray or roll initial
color coat DO NOT RE ROLL OR TOUCH UP
until initial color coat is dry. Failure to wait for
first color coat application of acrylic/latex to dry may
result in the color coat smearing or rolling off on the
roller. Once first color coat of latex/acrylic is dry
apply second coat. Top coating does not reduce
intumescent capability.
-
Tinting is possible to pastel shades only. Limit tint to
10% of paint volume.
