the finish coat. On extremely porous blocks, an additional coat of
block filler should be used. Avoid building a film on the face of the
block with block filler.
DESCRIPTION
#470A Acrylic Masonry Block Filler is a unique high solids latex
coating designed to fill voids, honeycombs and reducing pinholes in
interior or exterior porous masonry surfaces such as concrete,
heavy and lightweight masonry blocks. #470A has excellent alkali
resistance up to a pH of 13. #470A is designed to fill the porous
surface of concrete blocks and maximize the spreading rate of the
finish coating, giving faster production rates. This heavy duty block
filler may be topcoated with latex or alkyd coatings.

WARNING! Removal of old paint by sanding, scraping or other
means may generate dust or fumes that contain lead. Exposure to
lead dust or fumes may cause brain damage or other adverse
health effects, especially in children or pregnant women.
Controlling exposure to lead or other hazardous substances
requires the use of proper protective equipment, such as a properly
fitted respirator (NIOSH approved) and proper containment and
cleanup. For more information, call the National Lead Information
Center at 1-800-424-LEAD (in US) or contact your local health
authority.
GENERAL
The surface to be painted should be dry and free of any dirt, chalk,
loose or peeling paint, grease, mildew, oil, rust, efflorescence, bond
breakers or other surface contaminants. All cracks and mortar
joints should be repaired and repointed prior to application. All
new concrete surfaces must be properly cured before painting. All
new masonry surfaces require at least 7 days to cure and should
not be painted if the pH of the masonry surface is above 13.0.
MILDEW
Wash mildewed surfaces with a solution of 1 part household bleach
to 3 parts water. Scrub mildewed surface if necessary, and rinse

thoroughly. Follow bleach manufacturer’s directions for use and
wear appropriate protective equipment including eyewear, gloves,
and protective clothing. Wash any contacted skin immediately and
thoroughly with copious amounts of water. Never add ammonia or
detergents to a bleach/water solution.
If you have any questions about proper surface preparation check
your surface preparation guide or consult your Farrell-Calhoun
representative.
APPLICATION
PRECAUTIONS
Do not paint if the temperature of the air, surface, or paint is below
above 90°F or below 40°F and/or the temperature will go below
35°F for the next 48 hours. Do not paint late in the day when dew
or condensation is likely to form or when rain is threatening. Do not
use this coating for priming over old coatings or glossy enamels. If a
higher sheen topcoat is desired, we recommend priming with #697
Bonding Primer to completely seal the surface. This product is not
recommended on concrete floors or any other smooth concrete
surface or brick.
EQUIPMENT
Use an Airless spray with a .021 tip and a minimum 1.00 gallons per
minute pump. Use a quality synthetic brush or 1/2" to 3/4" nap
roller cover. This product is best worked into voids by roller or
brush application. When spraying, it is best to roll behind the spray
application while the material is still wet, so that the material can
be thoroughly worked into all the voids. This method of application
is especially recommended for split-faced block.
THINNING
Thinning is not recommended. If thinning is required for spray
applications, thin sparingly with clean tap water. Thinning in excess
of 1/2 pint of tap water to one gallon of paint will reduce hiding
power, void filling properties, and may cause sagging.
CLEAN-UP
Warm, soapy water
