How to Get Paint Off Wood

People remove paint for various reasons, from refinishing a piece of painted furniture, repainting your home's exterior, or painting your surfaces, walls, or paint splatters in your hardwood floors. In addition, learning how to remove paint can be great for correcting a poorly done paint job. So, are you wondering how to get paint off wood? Read on.

When it comes to removing paint, it's necessary to consider the materials and tools best for the job then weigh your options. Finally, determine which tools and materials will make the process easy and safe for you. We have written a step-by-step guide to remove old paint, paint spills, or chipped paint from wood surfaces and hardwood floors.

What are the Main Ways to Remove Paint from Wood?

There are three common ways to remove paint from wood, including chemical stripping paint, sanding, or heating. Each of these methods has a handful of different products to choose from.

a). Heaters

Heat guns remove paint from wood by using high temperatures to soften paint layers or varnish to allow the gunk to be easily removed using a plastic scraper. This heat gun paint remover method minimizes dust and can lift years of paint, and it is easy to learn how to use.

It works well for large surfaces, but it comes with risks, and you may need a little practice before you start using it. In addition, you should always wear long sleeves, use heat-resistant gloves, and have a fire extinguisher around for safety.

However, you should be careful since they can damage wood or cause it to catch fire, produce many fumes, and risk charred wood.

b). Chemical Strippers

Chemical paint strippers are gels, liquids, or pastes that dissolve paint with no paint chips or dust. They are suitable for awkward shapes, getting fine details, and removing paint in places you might miss using a heat gun. However, the chemical strippers can be smelly, slow, and messy.

c). Sanders

Sanders will grind paint on wood floors with clapboard sanders and power sanding disks. They are suitable for large yet flat exterior surfaces and are discouraged for use indoors unless they are hooked to a vacuum to capture dust when dealing with lead paint.

This sanding method of removing paint from wood is easy to learn and needs minimal tools. You should always wear a protective mask that filters dust particles when removing paint from wood to avoid getting the dust all over your house.

However, never use the sanders method to remove lead-based paint from wood because it might disperse fine particles in the air, and they may cause damage to your lungs, causing other serious health conditions.

What are the Steps to Get Paint Off Wood

Stripping paint can be a laborious and messy affair, and sometimes it can be better and more convenient to replace the wood. In addition, there are various ways to get the job done, from heat applications to natural approaches such as non-toxic paint strippers or sanding.

Before you strip paint, read and follow this step-by-step guide to remove paint using a chemical stripper to ensure you are doing it properly.

What You Will Need

  • A brush to apply the paint stripper
  • Microfiber cloths
  • Chemical paint stripper or natural
  • Heat-resistant gloves
  • Handheld sanding tool
  • Sandpaper
  • Handheld paint strippers or scrapers
  • A mask to protect yourself from vapors and dust particles

1. Check if the Wood is Worth Exposing

When planning to strip paint off cabinets, flooring, or furniture, ensure the wood below can be worked on after the paint is gone. This is necessary, especially if you finish the wood with a clear coat or a stain.

Find a small area of your wood where you can scrape to check the bottom layer and check if the wood was vanished originally and if it will look when good when it's exposed. If the bottom layer is painted, then it's a sign that the wood is unworthy of staining.

Rot is the most widespread problem you will detect, and dry rot spreads quickly and can ruin your wood. Check for any dry rot by checking for spore dust on the wood, a damp scent or the appearance of bodies of the fungus. On the other hand, wet rot occurs where there is moisture, which can be seen by warping or shrinkage signs.

For minor problems, remove the cause of moisture before you strip, replace the small holes, and allow the filler to dry, then sand it.

2. Check if the Paint Contains Lead

If the object or area had been painted before the 1970s, it could have lead paint on the surfaces. The lead dust can be toxic, especially children, once you start messing with it. Lead poisoning causes various symptoms, including developmental delays in toddlers and seizures.

Before you start to strip paint, test your surface first. DIY kits will give instructions on slicing through your paint and getting a small sample. Then, choose a sulfide-based or a rhodizonate-based kit depending on the paint color. If the paint turns out positive for lead, check the Environmental Protection Agency's website for tips on lead safety and how to remove it.

3. Determine if you Need Professional Help

DIY projects are always fun, but to remove paint, you may sometimes need the help of a professional with experience and specialized tools. Commercial paint removers usually remove paint from wood faster while still observing safety. Getting professional help might be especially necessary when dealing with lead-based paint.

When getting professional help, you can either decide to handle it in two ways:

a). Send to the Expert

This method involved sending out your affected area or surface to remove paint, like furniture, windows, or doors. This is a great way since experts can soak the entire pieces in liquid paint removers to achieve more thorough and faster results.

b). Hire In

Alternatively, you can hire in. This works well when you have a whole house that needs the removal of all the paint quickly, or you have lead paint. For certified experts to remove lead-based paint, visit the EPA's website.

4. Remove any Protruding Nails, Screws

Remove all your hardware screws, nails, brackets and doorknobs from your wood. Cover all the non-removable parts made of other materials such as wood using protective tape. Assess the condition of the wood and think how much of the previous coating will need removal.

Some jobs may not require chemical paint strippers, and you might prefer sanding. However, for minor jobs, such as getting past the peeling paint or making the surface smoother, you can skip the stripper step and choose sand.

5. Purchase the Necessary Paint Removal Tools and Protective Equipment

Having the proper tools and materials is necessary for a successful task. You will first need to decide the brand of chemical paint stripper you will use. Next, you should get accessories such as paintbrushes to apply the paint stripper, a cloth or a cleansing pad for cleanup and scrapers or sandpaper to remove the paint.

In addition, always observe safety precautions when dealing with paint strippers and be careful when selecting the right product. Finally, wear all the safety gear necessary, such as a respirator, gloves and glasses.

6. Apply Chemical Paint Stripper

Before you start to apply the chemical paint stripper, protect your floors under the wood, windows, wall edges or doors by taping or covering them. Most chemical strippers need to be on the surface for just a few minutes. Shake, then apply the stripper on the wood for about 20 minutes, or until the paint starts to peel or bubble.

However, when removing paint from a vertical surface like a door, use a chemical paint stripper in gel form or paste consistency. This prevents dripping down the surface onto your floor and causing damage. In addition, when removing layers of paint, the solvent may need to sit on the surface for longer to remove all the paint.

As time passes, intermittently test the paint from wood to see whether it has softened. Also, remove your applied stripper the same day because it can be difficult to remove once it dries.

7. Use your Paint Scraper to Remove the Paint on Wood

The best way to remove chemical paint strippers from wood is to use a bladed or plastic paint stripper, a putty knife and a wire brush for the hard-to-reach spots.

Follow the manufacturer's instructions and only use light pressure with your plastic putty knife to take off as much paint as possible but avoid damaging your wood floors or surfaces. You might have to re-treat some areas with a chemical paint stripper to remove the remaining paint stain.

If you feel more resistance to hardened paint, you might have to give the dried paint some more time under the stripper. Alternatively, if some chemical remains in some spots, dip your steel wool pad in paint thinner or mineral spirits to scrape the remaining stripper.

When satisfied with your wood floor or surface condition, wipe the surface using a damp cloth dipped in paint thinner. If not, repeat the process by reapplying the stripper and following the steps again.

However, never use paint thinner on water-based paint, but you can use it for oil-based paints.

8. Reach the Hard-to-Reach Areas

After you have worked by sections and removed paint from flat parts of the wood, it's time to deal with the recessed or raised areas such as moldings. Spread your chemical paint stripper on the wood floor or surface again and take steel wool or wire brush and try to remove paint from the hard-to-reach areas such as depressions and crests.

For fairly flat or large projects, you can attach a metal brush to a cordless drill which will help speed up your process. Notably, avoid scraping too hard as it can leave some scratches on your wooden surface.

9. Wash & Sand the Wood to a Clean Finish

Finish the process using a scrub brush to scrub all the excess paint and paint stripper, then wipe the surface clean using a cloth. The last step is critical if you are done stripping paint on the thick layers of paint.

The sanding and washing of wood are necessary to ensure the wood is free of loose materials like dirt and debris. Also, sanding gives the wood floor or surface a consistent surface to accept paint or stain. Before you sand, wash the wood with a clean damp rag and then sand down the surface and wipe the wood to remove any debris and particles left from sanding.

What are the Natural Ways of Removing Paint from Wood?

Chemical paint strippers can be harmful to your health and potentially dangerous when applied incorrectly. Although chemical paint strippers are straightforward, you can use more natural methods. They include:

1. Vinegar

Vinegar is a paint remover that does not completely remove the paint, but it can soften paint and make it easier for a paint scraper to remove old paint. Boil vinegar on your microwave or stove, apply it to the entire surface, then use a paint scraper after several minutes. Repeat the process with a fresh coat if there is remaining paint on your wood floors or surfaces.

2. Pressure Washer

This method is suitable for extensive projects such as a fence or a deck. To remove paint from wood on your home's exterior, ensure you prepare the area and protect it against any water leaking in the house. You should have a pressure washer with at least 2500 psi to successfully remove old paint.

3. Soy Gel or Citrus-Based Paint Removers

These paint removers are similar to chemical paint strippers but without chemicals and hence will be favorable for the paint splatter in your hardwood floor. This paint removal method is non-toxic and environmentally friendly but ensure you read the label and follow the instructions carefully.

4. Denatured Alcohol

Denatured alcohol is another paint remover alternative you can try at home, and you can purchase it from your local hardware store. Start by rubbing alcohol on the paint stain using a damp rag and allow it to soak the dried paint for about twenty to thirty minutes.

When the dried paint absorbs enough alcohol, it will easily remove paint from wood. Next, use a scrub brush to scrub the paint in a back and forth motion and wipe off the excess paint on the wood floor. After removing dried paint, leave the surface dry and ready for new paint.

What Tools Melt Away Paint?

1. Heat Guns

Heat is a tested method for softening thick old paint layers on flat surfaces or tight spaces. The trick to using heat guns properly is finding the right temperature.

Too low of a temperature could mean the job will take forever, but too high could create harmful vapors and hence char your wood floors and even cause a fire. Most heat gun models have high and low settings, but fires and burns can be caused even with the lowest setting if you let the gun stay in one place for long.

2. Infrared Devices

These devices use infrared rays to heat and loosen up the bond between the paint and the substrate without causing a lot of noise or generating a lot of dust. In addition, infrared devices are quick, and a 30-second blast can soften decades of old paint off wood floors.

They keep paint at temperatures below 500°F under the point which wood ignites. The heat gets moisture from the wood and improves the ability to hold new paint. However, it is a bulky tool and cannot be used in tight and hard-to-reach spaces.

3. Steam Strippers

Stream strippers remove paint from wood using water vapor, which softens paint without heating it above 212 degrees F, eliminating fire risks. Also, the condensation minimizes fumes and dust, but the process can generate a lot of moisture and saturate the wood floor.

How Should You Remove Oil-Based Paint from Wood?

Caustic strippers work well for removing oil-based paints from masonry, and it also works well on wood. However, the paint strippers can darken some hardwoods, such as maple. Special-oil-based paint strippers are very effective, but most of them contain VOCs and will need a lot of safety precautions to be observed, especially when used indoors.
