PRODUCT APPLICATION
SURFACE PREPARATION
Surfaces must be clean, dry, sound and free of nay contamination, mildew, rust or unsound coatings that may interfere with adhesion. If unsure, wash the surface with a low suds cleaning solution or a TSP substitute. For urine odors, avoid using ammonia. Rinse thoroughly and allow to dry.
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 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. 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 2000 to 2500 psi. Wear NIOSH approved respirator and provide adequate ventilation.
THINNING
Drywall Primer is formulated to be used without thinning. If thinning is necessary, add no more than 10 fluid ounces of clean water per gallon and mix thoroughly.
DRY TIME
Dries to the touch in 30 minutes, can be sanded or recoated in 1 hour. Lower temperatures and higher humidity will prolong dry and cure time. Allow more time at cooler temperatures.
CLEAN-UP
Clean up using warm water and liquid detergent. Wipe up splatters before they dry. If spills or drips have dried, use denatured alcohol or ammoniated detergent to soften and remove primer. Wash application tools in detergent and warm water immediately use. Follow equipment manufacturer’s directions to clean spray equipment. Dispose of unused or unwanted product in accordance with local laws regulating water-based coatings.
