depending on application method and surface porosity.
Surfaces should be clean, dry, sound and free of dust, dirt,
excessive chalky material, grime, grease, oil, wax, mildew,
wallpaper, adhesive or any contamination that may
interfere with adhesion. If unsure of cleanliness, always
wash surface with an appropriate cleaning solution or
solvent (do not use TSP as a cleaner). Remove any
peeling and/or unsound coatings. Sand any remaining
paint film edges smooth. When priming over stained
areas, first attempt to remove as much of the stain as
possible by washing, sanding, scraping, etc.
Allow surface to dry completely before priming. Spot prime knots
and sap streaks with B-I-N® Primer-Sealer before whole
surface priming with Zinsser Odorless Stain Blocker.
If you scrape, sand or remove old paint, you
may release lead dust. LEAD IS TOXIC. EXPOSURE TO
LEAD DUST CAN CAUSE SERIOUS ILLNESS, SUCH AS
BRAIN DAMAGE, ESPECIALLY IN CHILDREN.
PREGNANT WOMEN SHOULD ALSO AVOID
EXPOSURE. Wear a NIOSH-Approved respirator to
control lead exposure. Clean up carefully with a HEPA
vacuum and a wet mop. Before you start, find out how to
protect yourself and your family by contacting the National

Extinguish all flames and pilot lights, and turn
off all stoves, heaters, electric motors and other sources of
ignition during use until project is complete. Apply only
when air, material, and surface temperatures are between
40-90ºF (5-32ºC) and the surface temperature is at least
5ºF (3ºC) above the dew point. The relative humidity
should not be greater than 85%. Thoroughly mix with a
drill motor to ensure any settled pigment is re-dispersed
before using. DO NOT THIN. In most cases only one coat
is necessary to prime most surfaces. If excessive
absorption occurs over very porous substrates a second
coat may be necessary. For best results, prime entire
surface before painting. Apply with a natural or synthetic
bristle brush, roller, or airless sprayer. Follow
manufacturer's instructions when using spray equipment.
