Spray Paint Application Tips
Preparation
Clean surface thoroughly with degreaser. Sand glossy surfaces lightly. Use painter’s tape for clean edges. Always work in well-ventilated area.
Application
Shake can for 2-3 minutes. Hold 8-12 inches from surface. Use smooth, sweeping motions. Apply thin coats – 2-3 thin coats are better than 1 thick coat.
Drying & Curing
Allow 15-30 minutes between coats. Let final coat dry 24 hours before handling. Full cure takes 3-7 days. Avoid humidity and extreme temperatures.
Safety
Wear respirator mask, safety goggles, and gloves. Work in ventilated area or outdoors. Keep away from heat sources and open flames.
