How Long Does Acrylic Paint Take To Dry?

Acrylic paint is a versatile and popular medium for artists of all levels. But how long does it take for acrylic paint to dry? The answer may surprise you!

Generally, acrylic paint dries fairly quickly, typically taking 20 to 30 minutes to dry completely. There is no single answer to this question, as the drying time for acrylic paint can vary depending on a variety of factors like surface, temperature, thickness, application, humidity, paint type, air circulation, and the specific brand.

Keep reading to find out everything you need to know about the drying time of acrylic paint.

How Long Does Acrylic Paint Take To Dry?

As we mentioned before, the drying time for acrylic paint can vary depending on various factors. However, acrylic paint generally dries fairly quickly, typically within 20 to 30 minutes.

The main factors are the surface you paint on, the thickness of the paint, the brand and type of acrylic paint, and the humidity and temperature in the room. Keep these in mind when you’re painting.

Curing is a different process than drying, and it takes much longer for acrylic paint to cure completely. Curing is the process of the paint hardening and becoming permanent. Depending on the brand, acrylic paint can take anywhere from a few days to a couple of weeks to cure completely.

How Long Does Acrylic Paint Take To become Dry to touch?

The thickness of layers applied is the main factor in how long it will take for acrylic paint to dry to the touch. Generally, if you apply a very thin layer of paint, it will dry faster than if you apply a thick layer. The same goes for how much paint you use – using more paint will make it take longer to dry.

Using a retarder or medium in your paint can also affect how long it takes for the paint to dry. Retarders will make the paint dry slower, while mediums will make it dry faster.

The disadvantage of retarders is that they can make the paint a little transparent. If you’re using a retarder, make sure to test it on a small area before applying it to your entire project.

What’s the Difference Between Dry to the Touch vs. Fully Cured?

How does acrylic paint dry?

The two processes that occur when acrylic paint dries are evaporation and oxidation. Evaporation is the process of the liquid paint drying up and becoming a solid. Oxidation is the process of the paint molecules breaking down and hardening.

Curing is the process of the paint hardening and becoming permanent. Depending on the brand, acrylic paint can take anywhere from a few days to a couple of weeks to cure completely.

Drying is when the paint changes from a liquid to a solid. In general, acrylic paint dries fairly quickly, typically within 20 to 30 minutes. However, it may take longer for the paint to dry completely, depending on a variety of factors.

When the paint is dry to the touch, it means that it’s no longer wet, and you can handle it without getting the paint on your hands. However, the paint is not yet cured and may still be susceptible to smudging or fading.

When the paint is fully cured, it means that it’s hardened and permanent. The paint will be completely dry to the touch and will be resistant to smudging and fading.

Factors That Impact Acrylic Paint Dry Time

Type of Paint

The type of acrylic paint you’re using can also affect how long it takes for the paint to dry. There are two types of acrylic paint – artist quality and student quality. Artist-quality paints are made with higher-quality pigments and solvents than student-quality paints. This means that they have a higher sheen and will dry slower than student-quality paints.

Room Temperature and Humidity

The temperature and humidity in the room can also affect how long it takes for the paint to dry. Higher temperatures and humidity will make the paint dry faster, while lower temperatures and humidity will make it dry slower.

Surface Type

The surface you’re painting on can also affect how long it takes for the paint to dry. Porous surfaces, such as canvas, will absorb the paint more than non-porous surfaces, such as metal or plastic. This means that the paint will dry faster on porous surfaces than on non-porous surfaces.

Paint Thickness

The thickness of the layers of paint you apply will also affect how long it takes for the paint to dry. The thicker the layers of paint, the longer it will take for the paint to dry.

Paint Application

The way you apply the paint can also affect how long it takes for the paint to dry. If you brush on the paint, it will generally dry faster than if you apply it with a sponge. This is because the paint has more contact with the surface when it’s applied with a brush, which allows for faster evaporation.

Retarders

If you add a retarder to the paint, it will make the paint dry slower. Retarders are chemicals that slow down the evaporation of the paint. The disadvantage of retarders is that they can make the paint a little transparent. If you’re using a retarder, make sure to test it on a small area before applying it to your entire project.

Mediums

If you add a medium to the paint, it will make the paint dry faster. Mediums are substances that speed up the oxidation process. The disadvantage of mediums is that they can make the paint less glossy and more translucent. If you’re using a medium, make sure to test it on a small area before applying it to your entire project.

Varnish

If you add a varnish to the paint, it will make the paint dry slower. Varnishes are substances that slow down the oxidation process. The advantage of varnishes is that they can make the paint more glossy and help it to last longer. If you’re using a varnish, make sure to test it on a small area before applying it to your entire project.

Surface Absorbency 

The surface you’re painting on can also affect how long it takes for the paint to dry. Porous surfaces, such as canvas, will absorb the paint more than non-porous surfaces, such as metal or plastic. This means that the paint will dry faster on porous surfaces than on non-porous surfaces.

How Long Does It Take for Acrylic Paint to Dry on Different Surfaces?

Canvas 

Most Paints generally take about 10 to 20 minutes to dry on a canvas surface. But on unprimed canvas, the paint may take a few hours to dry.

Plastic

Most Paints generally take about 15 to 20 minutes to dry on a plastic surface. But on a glossy plastic surface, the paint may take a few hours to dry. Sealing it after painting will help avoid peeling.

Wood

Most Paints generally take about 20 to 30 minutes to dry on a wooden surface. But the paint will cure in between 6 to 12 hours.

Glass

Most Paints generally take about 24 to 72 hours to dry on a glass surface. Use primer post painting to avoid staining.

Metal

Most Paints generally take about 48 hours to dry on a metal surface. Sanding the metal surface will help the paint adhere better.

You’ll want to allow more time for drying if you are applying a thick coat of paint. In general, it’s a good idea to wait at least 10 to 20 minutes between coats, but you may need to wait longer depending on the paint and the conditions. If you are in a hurry, you can speed up the drying process by using a hairdryer or a heat gun.

How Can I Slow Down Acrylic Paint Drying Time?

Acrylic paint is a popular painting medium because it dries quickly and is easy to use. However, sometimes you may need to slow down the drying process so that you have more time to work on your painting. There are several ways to do this:

1. Add a retarder or varnish to your paint. This will add a layer of protection to your painting and will help to slow down the drying time.

2. Paint on a wet surface. When you paint on a wet surface, the paint will take longer to dry because it is mixed with more water.

3. Use a low-temperature setting on your oven. If you need to dry your painting quickly, you can place it in a low-temperature oven. This will help to speed up the drying process without causing any damage to the paint.

4. Use a hairdryer. If you need to dry your painting quickly and you don’t have an oven available, you can use a hairdryer. Point the dryer at the painting from a distance and keep it moving so that the paint doesn’t overheat.

5. Leave your painting in a draft. If you can’t do any of the above, you can also try leaving your painting in a draft. This will help to speed up the drying process.

By using one of these methods, you should be able to slow down the drying time of your acrylic paint and have more time to work on your painting.
