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, wash the surface with a low suds cleaning solution like ammonia or a TSP substitute. Rinse thoroughly and allow to dry. On exterior surfaces, remove unsound coatings, and sand paint edges and exposed wood smooth. Kill and remove any mildew. Countersink exposed nail heads, spot prime and fill with spackling compound. Wire brush rusty areas. Clean new galvanized metal with mineral spirits. Spot prime knots and significant water stains with Zinsser B-I-N Primer-Sealer. Use Zinsser Cover Stain to block exterior tannin bleed. Allow new masonry to cure for 30 days prior to application.
APPLICATION
Apply only when air, material, and surface temperatures are between 50-90ºF (10-32ºC) and the relative humidity is below 85%. Thoroughly mix to ensure any settled pigment is redispersed before using. Apply with a synthetic brush, roller, pad or sprayer. Follow manufacturer's instructions when using spray equipment. For airless spraying use a 0.017" tip at 2000 to 2500 psi. Wear NIOSH approved respirator and provide adequate ventilation.
THINNING
If thinning is necessary, add no more than 10 fluid ounces of clean water per gallon. Note that thinning the primer may affect its stain-blocking properties.
TINTING
PRIMECOAT2 can be tinted with up to 2 ounces of universal colorant per gallon. Tinting the primer helps improve topcoat hide.
COVERAGE
PRIMECOAT2 will cover approximately 300-400 square feet (27-37 m2 ) per gallon depending upon method of application and surface porosity. DRY TIME Dry times are based on 70°F and 50% relative humidity. Dries to the touch in 30 minutes and can be top coated in 1 hour. Unfinished wood sands to a powder in 1 hour. Full hardness develops in 7-10 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 application tools with warm water and liquid detergent. Follow equipment manufacturer’s directions to clean spray equipment. Dispose of unused or unwanted product in accordance with local laws regulating water-based coatings.
LIMITATIONS
PRIMECOAT2 is not recommended for applications to floors or decks or any surface subject to immersion or prolonged contact with water.
