Wood painting is a form of art that is getting popular these days. While many artists focusing on a wood painting might be new, there have always been cases of wood painting in general.

As the name suggests, wood painting is a form of painting that uses wood as the painting surface/canvas for the painter. This concept is relatively new, and therefore there are some misconceptions about the matter.

Unlike any other painting, wooden surfaces are much more robust, can get dampen quickly, and specific surface points can break off. There is also the matter of the paint being adequately attached to the surface in the first place.

To solve this issue, the proper way is to seal the paint after finishing your work on the surface. This method has been used by handymen and wood sanders to give timber a subtle glow and glossy finish.

And unless you are using oil paints, sealing your artwork on wood is the best possible option.

Why Do You Need to Seal Acrylic Paint on Wood?

You may ask yourself, if acrylic paint performs so well, why do you need to seal them to keep your painting accurate and stable. Well, the answer is that acrylic paints come off quickly on a wooden surface.

One of the perks of acrylic paints is that they are water-based and can easily be cleaned off from a brush. Well, the reverse is also true. As wooden surfaces don’t absorb the water like paper or canvas, the paint doesn’t properly stick in and can be removed via soap and water.

Not only this, but wooden surfaces can get dampen after excessive exposure to water. And as acrylic paints are water-based, this can hamper the wooden surface, and your artwork won’t last for long before it starts to fall apart.

This is why you need to apply a sealant to seal your acrylic painting if it has been done on a wooden surface or wood.

Sealing Acrylic Paint on Wood – Step-By-Step Guide

Sealing Acrylic Paint on Wood - Step-By-Step Guide

As there aren’t any other alternatives to protect your painted work, painters need to seal off their acrylic painting if they want to preserve it. But you can’t just add sealant and call it a day.

For preparing the wood to apply acrylic paint, you have to follow some essential steps, which we’ll discuss in detail now.

Step 1:Cleaning the Wood

Cleaning the Wood

You can’t start working on an uncleaned surface. So, before you begin to do clean the wood, you will be painting on.

Ensure that the wood isn’t dampened in any way and there aren’t any holes or broken parts in it as you will be moving to sand the wood in the following stages. So this process is essential.

If you are working on a pre-made wooden surface, make sure they are sturdy enough to endure sanding. Also, if you can pick the wood or wooden surface directly from a tree, make sure that the log was cleaned beforehand.

Step 2:Smooth Sanding the Wood

Smooth Sanding the Wood

This is the crucial part of the process, as many will ignore this step. If omitted, the wood you will be working on won’t be smooth enough, resulting in a wooden surface that isn’t properly prepped to handle sealant in the following stages of the process.

So, grab your sandpapers and start sanding. You need to fine sand the wood even if it is pre-sanded.
Because you need to work on a smooth surface if you want to paint using acrylic paint on that wood, the sandpaper grit will highly depend on your wood, but most of the time, a mid-range grit from 140 to 220 is helpful.

While sanding, you must ensure that you are sanding in the same direction as the gain. Gain is the lateral lines that you will find running across the surface in the same order.

Make sure to sand properly. Don’t sand too much so that your wooden surface becomes too fine. And at the same time, don’t sand too little because you will end up with an uneven and rough surface.

You need to have the perfect surface. You will understand that you have reached certain levels by seeing the gains and touching the surface.

Step 3:Cleaning After Sanding

Cleaning After Sanding

This is also an essential part of the process as there will be a lot of dust and dirt for you to clean up before you can go into the next steps. If you go to the next steps without cleaning, then you will endanger your artwork ultimately.

So, start by cleaning the surface with a microfiber cloth. Don’t hesitate to wash the surface with water but ensure not to use more than necessary as it will take excessive time to dry out because there will be excessive moisture if you do that.

Once the surface is dried, wipe it with the microfiber cloth again. Now, you can move on to the further steps.

Step 4:Applying Wood Sealant on the Surface

Applying Wood Sealant on the Surface

Don’t confuse this step with adding sealant after you have done painting on the wooden surface. This sealant is used to prepare and cover the wooden surface for you to paint on it without facing any hindrance.

Adding wood sealant on the sanded surface will ensure that there aren’t any gaps or holes left and the surface is ready to be painted.

Because this part prepares the surface for your artistic work, make sure that the sealant reaches every possible location on the surface. Especially the places where you know you will be using a lot of paint.

Don’t rush in with this section because the more thorough you are, the better the wooden surface will be for you to paint on. Work on small spaces and cover the entire area steadily and slowly.

Once you add the sealant, let the sealant completely dry out. If you think the sealant has been dried out completely, add another sealant layer to the surface.

This second layer is quite crucial as it ensures that the surface is appropriately covered with a sealant. Many try to rush in and find out later that the surface wasn’t properly sealed with the sealant.

After adding the second layer of sealant on the wooden surface, dry out the surface completely. We’d suggest you wait for a day at least to let the surface dry out.

Step 5:Prime the Wooden Surface

Prime the Wooden Surface

This is where many beginners confuse themselves. After using sealant on the wooden surface, you need to prime it once it has dried out completely. Newcomers think they will have to use sealant or prime on the wooden surface to make it acrylic paint ready.

But in truth, you will need to use them both. When you prime the wooden surface, it prepares the wood for acrylic paint. Therefore, this is very important if you want to use acrylic paints on your wooden artwork.

So, make sure to prime the wood. Because the primer will make the surface receive the paint properly. It also helps to adhere to the color better. This is entirely different than the benefits you get from a sealant.

For priming the wood, you have two options available. Those are brush primer and spray primer. If you plan to use spray primer, 2 or 3 layers can be used.

Now, if you plan to use brush primer, one layer of primer is enough, but you can add another to be safe. But don’t add too many, or you will ruin the wooden surface.

Step 6:Applying the Acrylic Paints

Now, this part is all you. We won’t suggest how the artist does his work. But a small tip is that you might need to use more color layers for the paintings to pop up. You will understand this matter once you start to paint with acrylic colors.

Step 7:Drying the Artwork

Drying the Artwork

You don’t directly add the paint sealant once you have done painting on the wooden surface with your acrylic paints.

You need to dry out the painting before you can do that. So, wait until the artwork is completely dry. In general, keeping the painted surface for one day will dry it out completely.

Step 8:Sealing the Acrylic Painted Wood

Now, this is the part that you have been reading this article for. Once the painted wooden surface is dried out completely, you can add the sealant.

Before adding the sealant, pick a dried clean cloth and widen the surface to remove the dust gathered during the drying process.
Once cleaned, you should proceed to add the sealant. Ensure that the sealant you are using is clean; otherwise, the colors won’t be as vibrant as before adding the sealant.

You have a couple of strategies for applying the sealant. You can spray the sealant via a spray can or use a brush to seal the artwork manually. You can also use a roller in this case.

It doesn’t matter which method you choose. Make sure that you cover the wooden surface from start to finish. You can use a sponge to reach harder angles.Keep in mind that once the sealant settles in, that will be permanent. So, there shouldn’t be any dirt on the surface.

Therefore, if you find any dirt on the artwork, carefully remove them with your hand or a pin before the sealant settles in. You can go for a double layer of sealant if you want to. But in most cases, that is not necessary.

And there you have it. This is how you can seal acrylic paint on any wooden surface, and your painting will face no loss in quality whatsoever. For that to be true, you will need to follow the mentioned steps to the point.

Apply The First Line Of Defense

We highly recommend sealing your project with a topcoat for extra protection. primer is also a great way to keep the paint job durable and water-resistant.
