MPI #36, #46, #136 Certified. Refer to the MPI website for the most current listing of MPI certified products.
INTERIOR
Apply to new and previously painted drywall, plaster, wood (pine, fir, cedar, redwood, and plywood), metal (aluminum, stainless steel, and galvanized metal), vinyl, PVC, fiberglass, and masonry (stucco, concrete block, concrete, brick). Blocks stains and odors resulting from water & fire damage, seals stains from dark colors, grease, rust, creosote, asphalt, crayon, lipstick, graffiti, markers, knots, sap streaks, tannin bleed, etc.
EXTERIOR
Use B-I-N Shellac-Base Primer to spot prime persistent bleed from knots and sap streaks before full surface priming with a water-based or oil-based primer.
SEALING
B-I-N seals unpainted or porous surfaces so topcoat paints have better coverage. It fills and binds wood fibers to create a smooth, sealed surface with “enamel holdout” so fewer coats of paint are needed. Very porous surfaces may require two coats which may reduce the square foot coverage of the product.
STAIN BLOCKING
B-I-N is an excellent interior stain killing primer. One coat effectively blocks stains, including water, nicotine, ink, crayon, marker, rust, and smoke stains so they will not bleed into the topcoat. Some stains require a second coat. B-I-N is recommended for permanently sealing heavy fire and water stains and odors caused by fires. It also seals in urine and other animal odors and is recommended for sealing nicotine stains and odors from tobacco.

PRODUCT APPLICATION
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 household ammonia and water solution, 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 with the surface. Remove existing stains by washing, sanding, scraping, etc. Countersink exposed nail heads, spot prime and fill all nail holes and gouges with Zinsser MH Ready-Patch® spackling compound or equally suitable material. Lightly sand exposed exterior wood with #80 to #100 grit sandpaper to remove loose or weathered wood fibers.
PLASTER & CONCRETE
New plaster must age 30 days before application of B-I-N Shellac-Base Primer. Concrete, plaster, masonry, and related surfaces must be fully cured before priming.
DAMAGED DRYWALL
Damaged drywall should be repaired prior to priming. Spot prime area of torn drywall facing paper or exposed gypsum core with Zinsser GardZ® Problem Surface Sealer and then skim coat with drywall mud before priming the total area with B-I-N Shellac-Base Primer.
MOLD & MILDEW
Kill exterior mildew with Zinsser JOMAX® House Cleaner 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 top coating. 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.
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.
NOTE: The use of 844 colorants may cause inconsistent mix and are not recommended
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.
CLEANUP
Clean up spills and paint drips with acetone, denatured alcohol, ammoniated detergent or 99% isopropyl alcohol. If spills or drips have dried, use denatured alcohol or ammoniated detergent to soften and remove primer. Dispose of unused or unwanted product in accordance with local laws regulating water-based coatings.
