2 oz. (59ml) universal colorant per gallon. Tinting the primer
towards the topcoat improves the hiding power of the

High Hide Cover-Stain seals porous surfaces with a
smooth, easily sanded film so paints have better coverage

nicotine, smoke, graffiti, crayon and rust. Cover-Stain
seals all types of wood, is an excellent tannin blocker and

300-400 sq.ft./gal. (7.4-9.8m2/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 Zinsser Jomax® 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

Cover Stain® Oil-Based Primer is not 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.
High Hide Cover-Stain is designed to be used without thinning.

Apply only when air, material, and surface temperatures
are between 40-90°F (4-32°C) and the relative humidity
is less 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 1800 to 2200 psi.

In most cases Cover-Stain will dry to the touch in 35 minutes and
can be recoated after 2 hours. The dry primer film develops full adhesion
in 4-7 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
