Extended Information:
Seals porous and moderately chalky surfaces to provide a
smooth finish that is easily sanded to enhance coverage
and provide consistent sheen to topcoat finishes. Zinsser
Odorless tolerates pH up to 12.5 which makes it ideal for
sealing porous, freshly cured plaster, cement, concrete
and masonry surfaces.

Zinsser Odorless effectively blocks stains from water,
nicotine, smoke, fire damage, graffiti, crayon, and pencil
marks with a bright white, non-yellowing, flat finish. Two
coats applied to ceilings may be left unpainted as a flat
ceiling paint.

350-400 sq.ft./gal. (8.6-9.8 m2/l)
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

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.

Airless spraying - use a .017" tip at 2500 to 3000 P.S.I.
