and Mildew Killer. Remove interior mildew stains by
washing the surface with a solution of one cup household
bleach in a gallon of water. Rinse well. Always wear
protective clothing and goggles to prevent eye and skin
contact with bleach. Do not add ammonia or other
cleaning products to the bleach solution. If concerned
about mold and mildew behind walls, underneath flooring,
in ventilation systems or other unseen areas, contact a
professional who specializes in mold and mildew
remediation. For commercial buildings and schools, follow
appropriate guidelines for mold removal.
WOOD
Bare wood that has been exposed for more than 4 weeks
should be lightly sanded with 80-100 grit sandpaper to
remove loose or weathered wood fibers. For new Cedar
and Redwood applications, allow B-I-N Shellac-Base
Primer to dry 24 hours before painting or topcoating. Sand
interior bare wood surfaces using medium to fine grit
sandpaper.
LIMITATIONS
B-I-N Shellac-Base Primer is not recommended for whole
surface exterior application or for application to floors,
decks, or any surface subject to immersion or prolonged
contact with water.
.PRODUCT APPLICATION (cont.) .
APPLICATION
Apply only when air, material, and surface temperatures
are between 0 and 90ºF (-18 and 32ºC) and the relative
humidity is below 70%. Do not apply B-I-N if surface
temperature is within 15°F of the dew point. Substrate
moisture should not exceed 12%. Do not thin. Thoroughly
mix to ensure any settled pigment is re-dispersed 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
finishes. For best results, prime entire surface before
painting. Keep container closed when not in use.
Apply with a natural or synthetic (nylon, polyester or
blend) bristle brush, roller, or airless sprayer. Follow
manufacturer's instructions when using spray equipment.
For airless spraying use a 0.011"-0.013” tip at 800 to 1200
psi. If a conventional sprayer is used, spray at 45-55 psi.
Wear NIOSH approved respirator and provide adequate
ventilation.
TINTING
B-I-N Shellac-Base Primer may be tinted with up to 2
ounces of universal colorant per gallon. Tinting the primer
toward the color of the topcoat helps hide in one coat.
Note: The addition of universal colorant may prolong the
dry time of this product.
DRY TIME
Dries to the touch in 20 minutes, can be recoated in 45
minutes. The primer film develops full adhesion and
hardness after it cures in 1 to 3 days. Lower temperatures,
higher humidity, and the addition of tint will prolong dry
and cure time. Allow more time at cooler temperatures.
CLEAN-UP
Clean up spills and paint drips with denatured alcohol or
ammoniated detergent. If spills or drips have dried, use
denatured alcohol or ammoniated detergent to soften and
remove primer. Wash application tools in a solution of 1
part ammonia and 3 parts water immediately after use. If
product has dried on application tools, soak tools
overnight in a solution of equal parts ammonia and water.
Scrub clean with a stiff brush. Follow equipment
manufacturer’s directions to clean spray equipment.
Dispose of unused or unwanted product in accordance
with local laws regulating water-based coatings.
