Technical Specifications

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, 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. 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.
Application requirements – Shake or stir 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.
Application methods – Apply with a natural or synthetic bristle brush, roller, pad or sprayer. Follow manufacturer's
instructions when using spray equipment. Airless spraying - use a .015" to .017" tip at 1500 to 2000 P.S.I..
Application conditions – Apply when air and surface temperatures are between 40
o
F and 80
o
F (4
o
C and 27
o
C) and
humidity is less than 85%.
Note that temperature and humidity directly affect the dry time of the product. Higher temperatures and lower humidity
will accelerate the dry time while lower temperatures and higher humidity will slow down the dry time.
Thinning – COVER STAIN
®
is designed to be used without thinning.
Dry Time – In most cases Coverstain will dry to the touch in 30 minutes and can be recoated after 1 hour. The dry
primer film develops full adhesion after it cures in 7 days. Lower temperatures, higher humidity and the addition of tint
will prolong dry and cure time.
Disposal – Dispose of unused or unwanted product in accordance with local laws regulating solvent-based coatings.
Cleanup – Clean up spills and 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 – rinse tools repeatedly in mineral spirits or paint
thinner until solvent runs clear and tool is thoroughly cleaned
