DESCRIPTION AND USES
Zinsser FastPrime is designed for interior applications where a heavy-bodied, fast-drying oil-based primer-sealer is needed. FastPrime dries in 2 hours to a flat finish that sands easily and accepts any latex or oil-based topcoat. FastPrime effectively blocks stains, bright colors, and graffiti on walls, ceilings, doors, trim, windows, and cabinetry.
NEW SURFACES
Bare wood, drywall, concrete and other unpainted surfaces absorb paint unevenly, frequently requiring multiple coats of paint to achieve an even finish. FastPrime Oil-Base seals interior drywall, joint compound, and cured plaster, cement, poured concrete, stucco, concrete/cinder block, wood and other porous surfaces. FastPrime Oil-Base is suitable for priming metal doors, windows, cabinetry and trim, aluminum, wrought iron steel and other metals, rigid paintable plastics, glossy laminates and other interior surfaces. Knots and sap streaks should be sealed with Zinsser B-I-N® Primer-Sealer. If necessary, lightly sand new drywall after priming to remove any raised nap fibers.
PAINTED SURFACES
FastPrime Oil-Base adheres to glossy surfaces without the need for sanding. It is suitable for priming walls painted with builder’s flat paint, spackled areas, and yellowed ceilings. Prime the entire surface to ensure uniform coverage and sheen.
STAIN KILLING
Effectively blocks common interior stains including water, smoke, nicotine, crayon, most types of markers and ink, graffiti and pencil marks, and prevents bleed through.

PRODUCT APPLICATION
SURFACE PREPARATION
Surfaces should be clean, dry, sound and free of any contamination, mildew, rust or unsound coatings that may interfere with adhesion. Remove loosely adhered or unsound coatings. Sand any remaining paint film edges smooth. 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). Rinse the surface thoroughly and allow to dry before application of FastPrime Oil-Base.
LIMITATIONS
FastPrime Oil-Base is not recommended for exterior application or for use on floors or surfaces subject to immersion or prolonged contact with water.
APPLICATION
Apply only when air, material, and surface temperatures are between 40-90ºF (5-32ºC) and the relative humidity is below 85%. Thoroughly mix to ensure any settled pigment is redispersed 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.
Apply with a synthetic (nylon, polyester or blend) bristle brush, roller, or airless sprayer. Follow manufacturer's instructions when using spray equipment. For airless spraying use a 0.015” to 0.017" tip at 1500 to 2000 psi. Wear NIOSH approved respirator and provide adequate ventilation.
TINTING
FastPrime Oil-Base 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. Shake or stir well before using.
DRY TIME
Dries to the touch in 40 minutes and can be sanded or recoated after 2 hours. Lower temperatures, higher humidity, and the addition of tint will prolong dry and cure time. Allow more time at cooler temperatures.
CLEAN-UP
Clean application tools immediately after use with paint thinner (mineral spirits). Wipe up splatters before they dry. Follow equipment manufacturer’s directions to clean spray equipment. Dispose of unused or unwanted product in accordance with local laws regulating solvent-based coatings.
