and pastel shades by adding no more than 2 oz. (59 ml)
universal colorant per gallon. Tinting the primer towards the
topcoat improves the hiding power of the topcoat.
400-450 sq.ft./gal. (9.8-11.1m2/l)
Depends on surface porosity and application method.
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 ammoniated 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. Lightly sand exposed exterior
wood with 80 to 100 grit sandpaper to remove loose or
weathered wood fibers and mill glaze. When priming over
stained areas, first attempt to remove as much of the stain
as possible by washing, sanding, scraping, etc. Remove
exterior mold & mildew with ZinsserJomax® Mildew Killer and
House Cleaner. Remove interior mildew with an
interior mildew cleaner. Allow surface to dry completely
before priming. Countersink exposed nail heads, spot
prime and fill all nail holes and gouges with Zinsser Ready
Patch® spackling compound. Wire brush rusty areas. Spot
prime knots and sap streaks with B-I-N® Primer-Sealer
before whole surface priming with Cover Stain Oil-Based
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
Cover Stain®Oil-Based Primers isnot intended for
application to floors, decks, roof surfaces or any surface
subject to immersion or prolonged contact with water. Do
not box or intermix Cover Stain Oil-Based Primer with
other oil-base or water-base products.
Mix thoroughly to ensure any settled pigment is re-dispersed.
DO NOT THIN.
Apply only when air, material, and surface temperatures
are between 40-80°F (4-27°C) and the relative humidity
should not be greater than 85%. Shake or mix thoroughly
before using. 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.
Spot priming is recommended only under high-hiding
topcoat paints. For best results, prime entire surface
before painting. Apply with a high quality natural or
synthetic brush, roller, pad or sprayer. Follow
manufacturer’s instructions when using spray equipment.
For airless spraying, use a 0.015 to 0.017" tip at
1500 to2000 P.S.I.
In most cases Cover-Stain will dry to the touch in 30
minutes and can be recoated after 1 hour. The dry primer
film develops full adhesion in 7 days. Lower temperatures,
higher humidity and the addition of tint will prolong the dry
and cure time.
Clean up spills and paint drips with a rag soaked in
mineral spirits or paint thinner. If spills or drips have dried,
use paint remover. Application tools may be cleaned using
paint thinner. Follow manufacturer’s directions to clean
spray equipment. Dispose of unused or unwanted product
in accordance with local laws regulating solvent-based coatings.
