How Long Does Spray Paint Take To Dry? (Surfaces Compared)

Innovative spray paint has made at-home paint jobs more effortless than ever, but DIYers still have to wait for the wet paint to completely dry.

While traditional brushes result in thick coats and uneven paint layers that can take days to dry completely, most spray paint cans disperse aerosol paint in a finer spray with just the touch of a nozzle.

Spraying paint thinner and more evenly with multiple clear coats, dry paint much faster than standard applications, but what’s the fastest way to dry spray paint? Read on to find out!

The 4 Important Stages Of Paint Drying

Surface dry
The first stage of drying, paint surface dryness, occurs once the paint's solvent fully evaporates. This is when the tacky paint eventually dry but still stains a finger if touched. Be sure to avoid smudging the rough surface at sticky spray paint dry time.
Touch dry
Touch dryness is, as the name implies, when the paint types can be gently touched by the painter's hands without smudging or stains. Many long spray paint takes a list “to touch” dry-times in addition to full spray paint cure time within next coat.
Hard dry
Once the freshly painted surface can be directly pressed without warping the paint, the layer has reached hard dryness. Although it may appear fully dry, we recommend waiting until the smooth surface has thoroughly dried before you apply spray paint in more clear coats.
Thorough dry
The final stage of thorough dryness can occur overnight or within 24+ hours, although curing can take 3 - 4 weeks. Once completely cured, both the lower level and surface of the too much paint are entirely dry and have hardened to their final finish.

Spray Paint Drying times (By Paint Type & Surface)

Enamel or latex acrylic spray paints
Latex and enamel paints are often rapid-drying, with some formulas drying to the touch within just minutes. Due to their glossy finish, the solvent within the enamel and latex paint quickly evaporates within just 10-30 minutes. As polymers link with one another to create a hard, durable surface, the latex paint typically thoroughly dries within 10 - 20 hours.
Lacquer paint
Lacquer paint formulas also depend upon solvent evaporation to help the dry, but some faster-drying lacquers use water as a thinner. Such formulas often use a thermoplastic polymer, which allows them to dry to the touch in just 5 minutes within next coat. Thorough dryness often takes 2 - 4 hours.
Polyurethane or Epoxy paints
Unlike solvent-based paints, epoxy or polyurethane paints depend upon chemical reactions as they dry. As acrylic paint brands increasingly tailor chemical formulas to their purposes, some epoxy paints dry within 5 minutes or less and reach a hard finish within just half an hour.
Spray paint on metal
Just 10 - 30 minutes is about how long does shake spray paint take to dry on metal. Its spray paint dry faster. As a non-porous metal surface that dries rapidly in warmer climates, you’ll find an hour or less is how long for Rustoleum spray paint to dry when painting metal.
Spray paint on drywall and wood
About 10 minutes is how long does general spray paint take to dry on wood or drywall between the next coat to apply thin layers unless you choose to lightly sand between the next coat. If so, 30 - 45 minutes is how long to let spray paint dry before sanding the wood lightly with 400 grit sandpaper.
Spray paint on plastic
As a non-porous plastic surfaces, plastic needs to be sanded or coated with a bonding primer to promote adhesion. Once prepped and lightly painted, about 15 minutes to touch and 1 - 2 hours to handle is how long does spray paint take to dry on plastic.
Spray paint on glass
Spray painting indoors like on glass is highly prone to streaks and running drips, so be sure to let it dry between light coats. We recommend waiting 15 - 20 minutes as to how long to let spray paint dry between how many coats, with glass fully drying within 24 - 48 hours.
Spray paint on rubber
As an extremely porous surface, rubber surfaces can soak up paint like a sponge. Usually drying to the touch within 30 minutes or so, we’ve found that 24 hours minimum is how long for spray paint to dry on rubber surfaces.

Factors That Can Affect Spray Paint Drying Time

Temperature
Temperature (like hot or cold weather) can highly affect the spray paint's drying time. Warmer weather lengthens dry time, but (cold weather)colder temperatures can freeze paint solid.
Paint brands will often list their preferred drying temperatures, but we recommend an ideal temperature range of 65° - 85° Fahrenheit.
Surface material
The texture and porousness of your metal surface can increase or decrease the mandatory dry time. More porous materials often take longer to dry, while sleeker surfaces such as metal surface can dry in just 10 minutes.
Thickness of paint
The viscosity of your preferred paint also influences the dry time, as water-based formulas will invariably dry faster than dense oil based paint or textured specialty sprays. Remember applying paint in thin coats, light and fully dried between applications.
Type of spray paint
Just as paint thickness can affect dry-time, the formula’s base and finish can play a big role. Enamel paint, for instance, can take up to 10 hours to dry fully, whereas lacquer spray paint often dries in just 2 - 3 hours.
Humidity
Since spray paint depends upon an uninterrupted aerosol paint spray, changes in the air’s humidity can warp a paint job and increase the dry-time. Try to avoid painting outdoors in humid or pre-storm weather.
Wind speed
Windy days can speed up dry times, but high-speed winds can also distort wet underneath paint into ripples. Even slight pressure or breezes can carry pollen, dust, or other particulates that run the risk of sticky paint, so consider using a paint booth to preserve your finish.

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.

Spray Paint Drying Time FAQs

How long does Rustoleum brand spray paint take to dry?

Although specialty Rustoleum sprays may have different dry-times, 15 minutes to touch and 24 hours for a thorough dry is average.

Is it dangerous to spray paint indoors?

Yes, but particularly without proper ventilation and safety gear. Aerosolized solvents and paint fumes can wreak havoc on painters’ lungs, and consider how long is spray paint toxic for, specifically 2 - 3 days for fumes, or until fully cured.

How long does spray paint stay in the air?

Without proper ventilation or an outdoor workspace, spray paint safe fumes can linger for two to three days. Never loiter in a painted space without a proper respirator mask as the fumes stay in the system for a long time.

Can you use a heat gun to dry spray paint?

Yes! You can use a heat gun to dry paint, but be mindful of chemical or oil based paint that may be flammable. We recommend sticking to a lower temperature, between 86 - 260 degrees Fahrenheit, and carefully drying the surface in slow strokes while holding the spray gun at a safe distance from the surface.

How can I speed up the drying process?

The best way to speed up spray paint drying time is a heat gun. But for how to speed up spray paint drying, you can also use a hairdryer as a low-tech substitute. And if you’re looking for a simple way of how to dry spray paint fast, using essential products such as ventilation fans and a dehumidifier in your workshop is sure to help.

Conclusion

With most paints, primers, and surfaces to choose from, it can be hard to find one standard rule of thumb for how long to let takes spray paint requires to dry.

By researching your choice of paint and surface carefully and following our guidelines, your paint coats are sure to dry in a flash. Spray on!
