By looking closer, I spotted stained marks and rusted smudges on my ancient furniture. To resolve this problem, I decided to do paint all the washed-out furniture.

On the spur of the moment, I purchased some spray paints and started coloring. But right on my mind, there’s a question buzzing that how long does spray paint take to dry? Will I be done before my guests come in? Finding answers to these questions in my subconscious mind. Meanwhile, I finished my coloring and managed to save my skin somehow.

But later on, I researched and found out every subtle detail about spray paints. And in this article, I will break down all the questions regarding spray paints. Especially about, “How long does spray paint take to dry?”

Know Your Surface Material

First of all, if you want to know how long does spray paint takes to dry, then you have to know about the surface material of the object.

Depending on surface texture, drying takes time. Products that come with smooth texture take minimal time. On the other hand, rough textured materials will be time-consuming to dry.

Apart from smooth and rough textures, there is a number of textured materials available in the market.

Drying in Terms of Different Textures

Here we’ve specified some textures that are being widely used. And according to these certain textures, drying time and other related procedures vary drastically.


Spray Painting on Metal

Talking about textures, metal textures are extremely common. This texture dries much quicker than other textures. But there are other things to keep in mind for metal textures. In case of excessive heat and humidity, the time for drying will be much longer.

So, the environmental fact is an issue here.

To make the process faster, keep the metal clean and tidy. Rub off the metal with sandpaper. The primary coating will not take more than 10-15 minutes due to rubbing.


Spray on Wood

Applying paint on wood textures is a bit slow. Naturally wood is less absorbent to colors, but if you clean the dirt over woods before painting, drying won’t take too long.

Generally, painters use sandpaper before painting. They rub off the textures with sandpaper, then start painting. Sanding helps to absorb the paint more effectively while reducing drying time.

Furthermore, try to apply three coatings at least. As I said earlier, wooden objects are not so sturdy to handle, so multiple coating is necessary to have great service.

Sand between the layers. Maintain 30 minutes break before applying another coat. This 30 minute is the resting period for colors to stay in place.

Finally, you can finish off the procedure by applying a heavy coating of color.


Spray Paint on Plastic

Normally, using spray paint on plastic materials is not recommended. One of the biggest cons of plastic materials is, spray paint colors don’t adhere properly to the object.

But if you want to color an object which is not so movable, then you can use spray paint on it.

Plastics are light weighted, so drying does not take much time. Yet, to make the best benefit out of it, sand it for 2 hours. Then apply the heavy coating for better results.

Phases of Dryness

There are three phases to go through for proper drying. Comprehending these three phases are necessary.

Surface Drying

This means neither absorbing water from nor contributing water to the material. In other words, vaporizing the solvent from paint is actually known as surface drying.

Surface drying might be a bit sticky. Because on the superficial side of the material, a thin layer is formed while painting.

Hard Drying

As it is named hard drying, meaning that your material will not allow any external pressure. Your color is completely dried, and you will only leave your fingerprints if you put extra pressure on it.

So, hard drying is the proper drying section that we can assume.

Touch Drying

Just simply touch your color and observe closely. By touching, external pressure is being put on the color, which ultimately results in sticking onto your fingertips and breaking the color as well.

How Can I Make Spray Paint Drying Faster?

If you are scratching your head thinking about making spray paint dry faster, you are in the right direction. Here are some tips and tricks to do so.

Add an Extra Coating

Understand one thing very clearly, faster drying but less impactful coloring leads you to spend multiple times. So, don’t waste your time for faster drying having no quality color.

Instead of this, quality coloring and faster drying is the most beneficial one to have. Try to double coat the material with colors. Apply a thin coating of paint for quicker drying.

Do not try to recolor over wet coating. Let the first coating dry. Then apply the second coating, and see the result. Applying an extra coating will provide you top-notch coloring with a smooth finish, also it will dry a lot faster. Check this article to know more about the reasons behind it.

Increase the Temperature

A bit old-fashioned but effective technique to use. Try to increase the temperature of the room or just near the object. Increased temperature will allow the color to haste the chemical reactions and make it dry faster than before.

You can also increase the temperature near the object you are working on for more efficient drying.

To help you in this case, a hairdryer could be a friend of yours. But if you are the guy who loves to paint outside, the mighty sun can help you definitely.

Reduce Humidity

This is another technique that many people ignore. If an increase in temperature seems difficult to implement, then a dehumidifier is a great option to reduce humidity.

Keep windows closed if you are painting on a wet day, or try to switch your painting in a less humid room.

In recent days, painters try to paint on a nice and warm day. They consider the facts about humidity and try to dry up the painting faster.

Still, it is recommended to work on a sunny day and an open place so that one can have both of the advantages of sun, as well as lesser humidity.  

Turn on a Fan

Getting the area heated up near the object is important, this will definitely dry up your object faster. But maintaining air around the object is also important.

In this regard, using a fan to circulate air around the object is a great idea. Doing such actually increases the evaporation rate. Large industries or factories use heavy-duty fans to make the drying process quicker.

If you are not working on big scales, use a normal fan. While using a fan, make sure that dust, dirt, and debris don’t come along with air.

Final Words
