Zinsser Odorless Oil-Based Stain Blocker

Description

Zinsser Odorless Oil-Base Stain Blocker is a high-solids, low VOC specialty primer for interior use when the stain blocking performance of an oil is required, but odor is a concern. Developed specifically for “people-sensitive” areas in commercial and residential environments, the state-of-the-art sprayable formula has even less odor than most water-base primers.

• Seals stains from water, fire and smoke damage
• Oil-base performance when odor is a concern
• Non-yellowing, dries flat, sands easily
• Use with all topcoats
• 350 VOC

Extended Information

SEALING

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.

STAIN BLOCKING

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.

COVERAGE

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

depending on application method and surface porosity.

SURFACE PREPARATION

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.

WARNING!

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

Lead Information Hotline at 1-800-424-LEAD or log on to

www.epa.gov/lead.

LIMITATIONS

Zinsser Odorless is not recommended for exterior

applications or for use under wallcoverings, floors, decks,

roof surfaces or any surface subject to immersion or

prolonged contact with water. Do not box or intermix

Zinsser Odorless with other oil-base or water-base

products.

APPLICATION

Important!

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.

Wear NIOSH approved respirator and provide adequate

ventilation.

Note: Compatible with water and alkyd-base

topcoats. Topcoats containing lacquer thinner, MEK or

similar strong solvents may soften primer and reduce

gloss.

DRY TIME

Dries to the touch in 30 minutes, can be recoated in

2 hours, and is fully cured in 7 days.

CLEAN-UP

Clean up spills and paint drips with mineral spirits or paint

thinner. Wipe up splatters before they dry. Follow

equipment manufacturer’s directions to clean spray

equipment. Dispose of unused or unwanted

product in accordance with local laws regulating solvent

-based coating.
