Application Method

Shake or stir 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 paints. For best results prime entire surface before painting. Allow to come to room temperature before use. Use in a well ventilated area avoiding high humidity. Shake can vigorously until ball inside can rattles. Turn can upside down and continue shaking for one minute, shake occasionally during use. Spray 10”-12” from object with short dusting strokes. Over-coatable after 30 minutes. To clean spray for future use, turn can upside down and spray until clear gas is emitted.
