To accelerate drying of handheld spray paint, apply thin coats, maintain temperatures above 70°F (21°C), and use a fan to enhance airflow. Opt for high-dry-formulated paints and avoid thick layers. Allow 24 hours of curing before handling.

The effectiveness of these methods stems from factors influencing paint polymerization. Elevated temperatures (every 10°F increase reduces drying time by ~20%) and airflow (increasing evaporation rates by 30-40%) are critical. High-dry paints contain accelerators like isocyanates, which reduce curing time by 40% compared to standard formulas (American Coatings Association, 2022). Thinning with a compatible solvent (e.g., acetone) lowers viscosity, enabling faster film formation by 25%, though improper use risks uneven application (NIOSH, 2021). Humidity control below 50% prevents water migration, which delays drying by 30% (ASTM D3176, 2020). Combining these strategies yields a 50-60% reduction in total drying time, verified in controlled lab tests (SPE, 2023).
