The 4 Stages of Drying the Paint

Surface Dry

During this phase, the solvent of your color begins to evaporate. During this period, the paint will form a fragile layer on its surface. It will most likely come off so quickly or stick to any surface, especially if you try to check it out

Touch Dry

At this period, the surface of the paint may become quite harder than before. It may not attach to your fingers when you touch it. However, it can still come off when you apply a slight pressure on the surface film.

Hard Dry

The layer may start to become dry. Then, it will not come off when you apply little force to it. But, the surface may get your fingerprints if you apply too much pressure on it.

Thorough Dry

In here, the surface finally dries completely. So, it is ready for your next steps.

Factors that Affect the Drying Time of Your Spray Paint

Before we reveal the answer to how long does the paint dries up completely, we have to discuss the different factors that impact the drying time. Here are as follows:

1. Character of the Surface

The surface that you choose to apply the pain will hugely affect the drying time of the paint. Metals ay dry slower or faster than other surfaces. But, it will still depend on the environment. But, the spray paint may dry up faster on metal when there is less humidity.

On the other hand, the paint will dry up more rapidly in brick or concrete surfaces than in metals. But, it will take longer for the paint to dry up on wood. That is because it can quickly get absorbed into the wood surface.

2. Thickness of the Paint Layer

The thickness of the spray paint plays a major role in knowing the drying time. A thicker layer of paint may take a lot of time to dry compared to a thinner coat. The consistency of brushing is more than that of the spray painting.

But, you can control the thickness of the spray paint by combining it with thinner or solvents, depending on its requirements. If you want to apply a double coat, make sure that when you apply the second coat, the first layer is dehydrated.

3. Environmental Conditions

Just like what we have mentioned above, your environment can significantly impact the drying time of the spray paint. Drying will become faster if it is less humid and hot in your working area.

4. Type of Paint You Apply

Also, it is an obvious factor. The drying time may vary from one paint to another.

The Process of Drying Various Spray Paints

Enamel Paint

It mostly happens in latex paints. During the drying process, the paint starts to dry in the first few minutes. That is due to the evaporation of the solvent. The air in the environment causes it to cross link from one polymer to another. Then, it creates a hard surface.

The surface may dry from 10 minutes up to 30 minutes. But, it will dry up completely when it reaches 8 hours and even a day.

Lacquer Paint

It will work through the process of solvent evaporation. You may find this in some types of latex paints which make use of water as the thinner. These are mainly from a thermoplastic polymer. In this case, the surface drying time may take up to 5 minutes. But, it reaches its hard, dry stage from 2 to 3 hours.

Polyester/ Polyurethane/ Epoxy Multi-pack Paint

For this kind of paint, it will dry up with the use of chemical reaction between its two main ingredients. The drying time may become faster and will take around 5 minutes or less. For it to reach hard dry state, it will take 30 minutes or so.

How Long Does Spray Paint Take to Dry on Different Materials?

The nature of your spray paints are all the same, but the contents may differ. The duration of the drying time may vary from one material to another. So, the drying time of wood may vary with glass, metal, plastic, and rubber.

But, remember that low-quality paints may take a longer time to dry compared to high-quality spray paints. Plus, they will come off so quickly. On the other hand, high-quality paints are wash-resist and can give you a beautiful base.

With that aside, the average drying time spray paint for any material will take 30 minutes to an hour. But remember that this can vary based on the materials you are using for your project.

Wrapping Things Up

For all do-it-yourself enthusiast, it is crucial to check whether the spray paint is already dry or not, especially if you are in a hurry. Take note not to use your hands to assess the coating. That way, you may end up blemishing and destroying the surface of your project.

The best way for you to find out if your paint is already dry and is ready for the next steps is to smell it. If you can still smell its sharp odor, then it has not yet set it correctly.
