Innovative spray paint has made at-home paint projects more effortless than ever, but DIYers still have to wait for the paint to dry.
Although traditional brushes result in thick, uneven layers of paint that can take days to dry, spray cans disperse aerosolized paint in a fine spray with just the touch of a nozzle.
Spray paint’s thinner, more even coats dry much faster than standard applications, but what’s the fastest way to dry spray paint? Read on to find out!
Factors That Can Affect Paint Drying Time
How Long Does A Spray Paint Dry (By Paint Type & Surface)
How To Check If 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 does it take for spray paint to dry between coats, fully cured paint can take up to 60 days.
For best results, be sure to read all paint instructions carefully and learn how long to let primer dry before spray painting—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.
