If
you purchased this product palletized – immediately
check all containers for damage; opened paint cannot be
‘salvaged’ and a carrier claim will need to
be filed for replacement.
HANDLING
INSTRUCTIONS:
- DO NOT allow this product to freeze. If frozen the intumescent
properties of this product may be adversely affected.
- Do not allow storage temperature to exceed 100 degrees
F (38 C).
- If possible, store this product above 65 degrees F (18
C) for 48 hours prior to application – this will
aid you during the application process.
- Do not reuse opened paint after 48 hours; the curing
process has begun and may affect the product’s
performance.
- If you wish to set some paint aside for future touch-up
work fill a small clean container completely with fresh
paint from a 5 gallon bucket after it has been mixed
as described in the ‘Application’ section
below and then seal tightly.
APPLICATION
INSTRUCTIONS:
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.

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).

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.
