Regardless of what project you are doing with paint, from a school project, or you may be a professional artist, you will always be concerned that the paint will accidentally splatter or spill, particularly if your workspace has a wooden surface, such as a desk, floor, a table, or any other wooden furniture. Acrylic paint dries especially quickly, and if you fail to remove the paint while it is still wet, you may find it hard to remove. There are, thankfully, many different techniques for getting acrylic paint off of wood, but they will all mean you will be doing some hard work. So, let’s look at how to remove acrylic paint from wood.

 

 

What Is Acrylic Paint?

Why is it concerning when you spill acrylic paint on wood? When the acrylic paint has dried, it forms a solid hard surface, that is very durable, making it challenging to remove the paint. Water-based acrylic paint for woodwork consists of three components, which are binder, pigment, and vehicle.

Artists Acrylic Paint Consistency

 

Pigment

The pigment of acrylic paint for woodwork consists of granular solids that result in the color of your paint. these are broken up or crushed up, and form tiny particle sizes which do not dissolve but remain in the paint suspended. These granular particles or pigment particles can e natural, inorganic, synthetic, or organic, and are in no way similar to the surface to that they have been applied to.

Pigments to Make Acrylic Paint

 

Binder

The binder ingredient or material assists in holding the pigment to the surface once the paint has completely dried. Acrylic paint uses an acrylic polymer as a binder that creates a layer or film over the surface of the paint, once the water has completely evaporated.

 

Vehicle

The vehicle is what transports the pigment and the binder. Acrylic paint’s vehicle is water, which forms a polymer emulsion when combined with the binder. Once the paint has dried (as a result of the watering evaporating, or being absorbed), the results will be a durable, clear polymer film. It is this film that allows the color to remain on the surface of your artwork or workpiece.

Acrylic Paints on Wood

There is more to acrylic paint for woodwork than just these three components. As the pigment sits on top of the water, some acrylic dispersant is incorporated to ensure the paint has a consistent mixture. The paint is made more effective through other additives being included.

ADDITIVESROLE
BuffersThese additives are there to assist in keeping the pH level more stable, ensuring that the paint is more durable.
InitiatorsThese form a polymer film throughout the drying process, by activating the polymerization process.
Defoamers and SurfactantsThese have been added to assist with the drying process.
PreservativesThese additives assist in any microorganisms from growing on the paint.
Stabilizers and ThickenersTo assist in thickening the paint to the required thickness, whilst also creating some texture in your art piece.

 

 

Required Elements for Removing Acrylic Paint From Wood

When the water has been absorbed or has evaporated, and the acrylic paint has completely dried, the acrylic paint film will form thanks to the polymer molecules, which are no longer water-soluble. This is why it is necessary to remove the acrylic paint before it has dried, otherwise, you will be forced to use a substance that is capable of dissolving the acrylic resin.

How to clean Dry Acrylic Paint from Wood

Sometimes it is not possible to remove the paint spill before it has dried, as you may not be aware of the spill until it has already dried. Once dried, you will not be able to remove acrylic paint using only water. Luckily it is not too hard to remove acrylic paint from a wooden surface as the majority of products are fairly affordable and readily available. You will not have to use any form of power tool that could potentially damage the wooden surface.

Wet a clean cloth with some water, and then rub at the paint stain with the cloth. Whilst rubbing, ensure you are using adequate pressure. When you see that the cloth has become saturated, swap the cloth out for a clean cloth. Wet the fresh cloth, using some hot water, and apply some bar or liquid soap. The best soap is glycerin soap, but any type of soap will work as long as it can produce some decent lather. Carefully use the cloth to scrub any remaining acrylic paint from the wooden surface.

Gloves and Cloth to Clean Acrylic Paint

You should be rubbing with the grain of the wood, maintaining a straight line while you work. If required you can add some additional soap and use a new clean cloth. You want to ensure that you have removed all the paint, including any which has gotten into the wood’s grain. Next, you will need to take a clean cloth and wipe down the whole wooden surface so that all traces of the paint and soap have been removed. When you have finished scrubbing down the wooden surface, allow it time to dry.

How to Remove Dried Acrylic Paint From Wood

The acrylic paint will have dried after roughly 20 minutes, which means it will be significantly more challenging to remove the spill. You can attempt the water and soap method, and if you are lucky, you may have gotten to the spill in time, and it will work. However, if the paint has dried there are other methods to turn to, to deal with the problem of how to remove dried acrylic paint from wood.

Choose Your Solvent

Paint solvents are an efficient method to remove acrylic paint from a wooden surface and can be done quickly. You can choose to use chemicals such as ammonia, methylene chloride, paint stripper, or thinners. The most commonly chosen product is methylene chloride. This is a more environmentally friendly solvent than the other options, but is still a very toxic and dangerous chemical and should be used with care. You will need to ensure that all safety equipment and safety precautions should be used when using any form of solvent.

Using Solvents to Strip Acrylic Paint

 

Put on Safety Gear

The fumes are particularly dangerous and toxic, you will need to wear the necessary safety gear to ensure you are adequately protected. It is necessary to wear the relevant protective gear, including gloves, goggles, and a mask (or respirator). It is paramount that you are working in a well-ventilated space.

Apply the Solvent

Use either your paint roller or paintbrush to apply a thin layer of solvent over your paint stain. Ensure that you do not pour the solvent straight onto the wooden surface as this can be extremely dangerous for both you and others. After roughly 20 to 30 minutes the paint will begin to bubble. This illustrates that the solvent is working.

Applying Solvent to Acrylic Paint

 

Remove the Paint

Scrape the softened paint off using either the scraper or your putty knife. Work in the direction of the wood grain and be careful to not push down too hard as this can damage to the wooden surface.

Cleaning Up

Apply some mineral spirits to a dry clean cloth, then wipe down the entire wooden surface using the cloth. You want to ensure you remove both the solvent and the paint residue. Use another clean cloth soaked in water to wipe down the wooden surface again. This will ensure that the solvent is neutralized completely. Then allow sufficient time for the wooden surface to completely dry – this will take roughly one week.

 

Using a Heat Gun

For this particular method, you will need to initially establish if the area where the paint is, is a large enough space to justify the use of a heat gun. This is because a heat gun will only be effective to remove acrylic paint from larger wooden surface areas like furniture or a complete door. The use of a heat gun requires exposing the paint-stained surface to an extremely high temperature of over one thousand degrees Fahrenheit. The exposure to the heat will cause the paint to bubble and peel off in just seconds. In addition to the heat gun, you will require the following materials.

  • Heat gun
  • Clean cloths
  • Heatproof gloves
  • Putty knife or scraper
  • Goggles
  • Respirator or mask

Removal of Acrylic Paint with Heat Gun

 

Take All the Necessary Precautionary Measures

To begin with, you will need to read the instructions that you received with the heat gun and ensure that you follow them carefully. You will need to put on the relevant safety equipment, for example, safety goggles, heatproof gloves, a respirator, or a mask, and of course, the area you will be working in requires adequate ventilation.

Remove Paint in a Ventilated Area

 

Heat the Paint

Use a clean cloth to remove any dirt or debris and plug the heat gun into the power source. Switch it on and set the gun to the desired temperature setting. Firmly hold the heat gun in your hand, and allow a few seconds for the gun to fully warm up. We recommend you try a small section of the wooden surface, to begin with, to determine how it works. Aim the gun towards the paint stain and hold it roughly three to four inches away from the wood’s surface. Move the heat gun in a circular motion, working carefully as you go. Ensure that you do not exceed more than 10 to 20 seconds as any longer the heat could potentially damage the wooden surface.

Using Heat Gun with Scraper

 

Scrape the Paint Off

Hold the gun in one hand and the putty knife or scraper in the other hand. As soon as the paint begins to bubble, use your scraper to flick the paint off the surface. Work on a small patch at a time, and clean the mess from your scraper before you have any type of buildup. Work carefully so as not to damage the wooden surface, and continue the process until all the paint has been removed.

Wipe the Wood Surface Clean

Once the wood has cooled down, you can remove the residue by wiping down the surface using a clean cloth. You can clean down the surface using some rubbing alcohol, or just simply use soap and water.

 

Sanding the Wood

This is a great method to use if you are just learning how to get acrylic paint off wood. However, this tends to be extremely time-consuming and strenuous. This is the preferred method to use for unfinished wood, such as furniture like tables and chairs.

Sand Acrylic Paint off Wood

By sanding down the stained area, you will be able to remove the paint from the wood surface. You can either sand down the surface using sandpaper or a sanding block. Or, if you wish to decrease the amount of time it takes, you can use a power sanding machine. In addition to the sanding paper, you will require the following materials.

  • Sandpaper (80 to 150 grit)
  • Clean cloths
  • Sanding blocks
  • Goggles and gloves
  • Power sander if required
  • Clean hot water
  • Respirator or mask

Sanding Block for Acrylic on Wood

 

Sand the Wood Surface

Begin by removing any stray dirt or debris by wiping the surface down using a clean cloth. Ensure that you are wearing the necessary safety equipment like a mask, goggles, and gloves, and ensure the space you are working in is well ventilated. The sandpaper should be wrapped around a sanding block, once done you can begin sanding. Use a circular motion when sanding, and work in the direction of the grain of the wood. If you do not follow the grain you can leave unsightly scratches on the surface of your wood.

Take Care Not to Scratch Wood

If the paint stain covers a larger area, then we suggest you use a power sanding machine. The sander will require an 80-grit sanding disc. Work carefully when sanding the wooden surface, so you do not damage it in any way.
