You’ve sanded your project to a smooth finish, applied a primer (if needed), and now it’s time to paint. But how long do you need to wait between coats? In this helpful guide, we’ll give you all the information you need to know about how long to wait between coats of spray paint, so your project turns out looking its best.

How long should you wait between coats of spray paint?

It is best to wait at least 15 minutes between coats of spray paint. If the paint is applied too thickly, it can take longer to dry.

The importance of waiting between coats

One of the most common mistakes people make when painting is not waiting long enough between coats. If you don’t wait long enough, the paint will not have time to properly dry and set, and it will damage the surface you’re painting. The best way to avoid this is to read the instructions on your paint can, which will usually tell you how long to wait between coats. In general, you should wait at least two hours between coats of paint, but preferably longer if possible.

How to ensure even coverage when painting

It’s important to get even coverage when you’re painting, otherwise you’ll end up with streaks or brush marks. One way to ensure even coverage is to wait the recommended time between coats of paint. Most paint cans will have a suggested time listed on them, and it’s usually somewhere between 30 minutes and 2 hours. If you can wait longer, that’s even better.

Another way to get even coverage is to use a paint sprayer. Paint sprayers are especially helpful for large projects or for painting difficult-to-reach areas. They can also help you avoid brush marks and streaks. When using a paint sprayer, it’s important to follow the manufacturer’s instructions carefully. You’ll also need to thin the paint before adding it to the sprayer, and you may need to apply multiple coats in order to get even coverage.

The best way to avoid paint drips

To avoid paint drips, allow the paint to dry for about an hour in between coats. When you are finished painting, clean the areas where you painted with soap and water.
