How many days does it take for paint to dry?

Automotive painting requires at least one day. Painting in a paint booth: If the vehicle is painted in a paint booth, since it has already stayed in the booth for 3-4 hours, it can be washed immediately after being taken out. For vehicles painted at an authorized 4S shop, they can be washed when the staff delivers the vehicle, as the vehicle has completed the standard painting process. Just remind the car wash staff to be careful. Precautions for automotive painting: If spraying a single door panel and the orange peel effect is too pronounced, don't worry—there's a solution. You can add blending solvent to the clear coat. The ratio is 50 parts of mixed clear coat to 100 parts of blending solvent. Then, spray it evenly, being careful not to hold the spray gun too close to avoid runs. Just apply an even coat of gloss.
My car was just repainted a few days ago, and the mechanic told me that it takes at least 24 hours for the paint to dry completely, but full curing can take 3-7 days depending on the situation. For example, with the water-based paint we commonly use, the surface hardens within a few hours after spraying. In hot summer weather, it dries faster and might be safe to drive after two days, while in cold and humid winter conditions, it could take four to five days. The thickness of the paint also matters—thin coats dry faster, while thick coats take more time. Paint applied to plastic parts dries slower than on metal. Professional shops use ovens to speed up the process, usually finishing within 24 hours, but for DIY projects, you need to be patient. Avoid rain or scratches on the first day after painting. I once rushed to wash my car right after painting, and the paint got ruined, forcing me to repaint it and waste money. I recommend leaving the car in the garage for three days after painting before normal use to ensure the paint is solid and won’t fade—don’t take risks to save time.
At our repair shop, we get asked every day how many days it takes to pick up the car after painting. Last week, a lady came in to have her car door painted. We told her it needs at least one night, 24 hours to dry, before she can drive it, but for full curing, it takes two to three days, especially with eco-friendly paint which takes even longer. In winter, with the cold and humid air, it might extend to a week, as we have to wait for the paint to fully dry to avoid chipping from road debris. In hot weather, it's easier—the surface stabilizes in about 20 hours. Before painting, the area must be thoroughly cleaned, and after painting, avoid dust accumulation. Don’t wash the car for a week. Once, a customer drove long-distance just half a day after painting, and the touch-up for the chips cost more—really not worth it. In short, painting isn’t an instant process. Follow the advice to let it sit for 48 hours to avoid trouble.
