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, higherhumidity, and the addition of tint will prolong dry and cure time. Allow more time at cooler temperatures.
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 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.
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.
