Spray Paint Drying times (By Paint Type & Surface)
Factors That Can Affect Spray Paint Drying Time
How To Check If The Paint Is Fully Cured
Remember that curing almost always takes longer than one would expect. Although just 30 minutes to a few hours is how long it takes for most types of paint to dry between coats, fully cured paint can take up to 60 days.
For best results, be sure to read all paint layer instructions carefully and learn how long to let primer dry before acrylic spray paint—generally overnight, or 24 hours.
If you’ve applied both paint and primer properly, curing generally takes about 3 weeks. Fully cured paint will be dry to the touch, can be wiped with a cloth without smearing, and will not smell of paint.
To check, we recommend pressing a fingernail into an inconspicuous corner of the painted surface. If an imprint remains, the paint needs to continue curing.
