You can use spray paint for a variety of different projects, but something that you might be keen to know is how long it will take for the paint to dry.
There is no easy answer to this question, as different types of spray paints will take different amounts of time to dry.
There are also lots of things that can influence the amount of time that it takes for the spray paint to dry like the environments that you are in, the material that you are spraying, and even the brand of paint that you are using.
If you are wondering how long it will take for your spray paint project to dry, we will do our best to tell you.
We are going to look at the different things that can make it take longer to dry, how you can speed up the process, and the different types of paints that you can use.
By the end of this article, you will have a better idea of what to expect when it comes to waiting times.
How Long Does Spray Paint Take to Dry?
Under the best conditions, spray paint shouldn’t take longer than 2 hours to dry to the touch and 24 hours to be completely dry.
The optimal conditions for spray paint to dry are 5-85 degrees F and 70 percent Humidity.
The paint should be applied in light and even coats, and it shouldn’t take more than around half an hour for you to be able to apply additional coats of paint.
You should always avoid using excessive amounts of paint, as this will only lead to even longer drying times and a poor-looking finish.
These times may vary, depending on the type of paint that you are using and the brand that it comes from.
However, you should be able to find instructions for the exact drying times for the product you are using on the can. Always read the instructions to find out more about drying times.
How Materials Can Influence Spray Paint Drying Time
Something that can influence the amount of time that it will take for the paint to dry is the material that you are spraying it on.
Raw wood and cement are two materials that are very porous, which means that they will soak up the paint more quickly, enabling it to dry faster.
Other materials, like plastic and metal are not porous, which means that they will take longer to dry.
Different Stages of Spray Paint Drying
There are different stages of drying when you are using spray paint, and if you are looking to find out how long it will take for your paint to dry, then it can help to understand these stages.
We will explain the different stages of drying spray paint below.
- When the solvent of the paint begins to evaporate, it is known as surface dry. There will be a thin layer of paint on the surface during this stage, and this layer can become sticky, so you should take care not to touch it until it is dry.
- The next stage of drying is dry to the touch, which means that you will be able to touch this top layer of paint. However, if you try to apply even the smallest amount of pressure, the paint will smudge and stick to your finger.
- The third stage of drying is hard dry, and this is when the paint will be dry, but you shouldn’t apply any pressure on it as your fingerprints will be left behind. At this stage, the paint will not be sticky enough to stick to your hand when you touch it.
- The final stage of drying is the thorough dry, and this is when the paint will be completely dry all the way through. You will be able to touch it and put pressure on it without damaging the paint job, and your project will be ready to use.
Types of Spray Paint
There are many different types of spray paints that you can get your hands on, and each of them will work slightly differently when it comes to drying.
If you want to know how long your paint will take to dry, learning about the type of paint will help you to learn more about this.
Enamel paint will actually start to dry within minutes, and this is due to the evaporation rate of the solvent.
Once the paint application is complete, it will take between 10 and 30 minutes for the surface to be dry, and around 8 hours for it to be completely dry.
Lacquer paint will also dry really quickly. It is made using a thermoplastic polymer, and the surface will dry within as little as 3 to 5 minutes, and it will be fully dry within around 3 hours.
Epoxy or Polyurethane Paint
These types of paint are one of the fastest when it comes to drying times, and you will only have to wait for the two chemicals to react.
This is the fastest drying spray paint on the market, and it will be dry to the touch in around 5 minutes. This paint will be completely dry in around an hour.
How to Make Spray Paint Dry Faster
- Only apply a thin layer of paint, as the thinner the layer is, the quicker it will dry. If you need more coverage, wait for the first layer to dry before applying another.
- Make the room warm if you can because higher temperatures will help the paint to dry faster. It might not increase the drying time by long, but it will certainly help.
- Try to decrease the humidity in the area that you are painting as much as you can. A dehumidifier can help with this.
- If it is a warm and dry day, take your spray-painting project outside instead of doing it inside.
- Circulate the air using a fan to increase the rate of evaporation in the paint and help your project dry.
