Types of Removers

Paint strippers and removers eliminate all types of paint and finishes to reveal an object’s original surface. Removers are available in consistencies ranging from thin liquids to thick semi-pastes. Semi-paste removers cling to surfaces, making them ideal for vertical or overhead applications.

Biochemical and non-toxic strippers are not as harsh. They can take as long as four to 24 hours to fully penetrate the surface, depending on the size of the project, and can strip as many as seven layers of paint.

Solvent

• These removers work well on metal and masonry and can take off epoxy and polyurethane.
  They are among the best paint strippers for wood.
• The active ingredients in solvent removers are typically toxic chemicals, which means increased health risks when you use them. These removers generally have strong fumes because they contain volatile organic compounds (VOCs).
• They can make you feel dizzy or give you a headache. These removers can also cause cancer, as well as lasting damage to your liver and kidneys.

Caustic

• The active ingredient in these water-based strippers is lye. It reacts with the paint to form a soap, which can then be more easily worked loose from the surface of the item.
• Use these removers on concrete floors, brick fireplaces and other masonry that has been painted with oil-based paint.
• Caustic removers can sometimes work to take paint off items made of metal or wood. However, they can leave stains on wood and break down metals such as aluminum.
• These removers can injure your lungs or skin.

Biochemical and non-toxic strippers are not as harsh. They can take as long as four to 24 hours to fully penetrate the surface, depending on the size of the project, and can strip as many as seven layers of paint.

Biochemical

• Made with solvents that come from plants, these removers are safer substitute for solvent and caustic products.
• When used on masonry, metal and wood, these kinds of removers can take off water-based and oil-based paint.
  They can be considered one of the best paint strippers for wood.
• They will not work for epoxy or polyurethane.
• Still, they can harm your skin and respiratory system, as well as your reproductive system

Non-Toxic

• These removers work best for getting oil- or water-based paint off metal and masonry. They can also be used on some types of wood.
• Don’t expect them to perform well on epoxy or polyurethane.
• While non-toxic removers are among the safest products, you will still need to use protective equipment to keep them from irritating your lungs and skin.

Tip: Once you've successfully stripped paint or finish, wait until the stripped paint or epoxy dries before disposing of it.

Types of Solvents

Solvents are used to dissolve or thin paint. They're also used paint preparation or cleanup. After a remover has been used, solvents are often needed to clean and prep the surface to receive a new finish.

Here are some of the most common types of solvents:

• Mineral spirits: This petroleum product is a budget-friendly and less toxic substitute for turpentine. You can use mineral spirits to remove paint, clean paint brushes and thin varnish and oil-based paints. Its liquid and vapor are flammable.
• Turpentine: Derived from tree resin, this organic solvent is often used by artists to thin and remove paint. It can be used to remove oil-based paint, acrylics, varnishes, tar and tree sap. It can be used as a thinner for oil-based paint, but shouldn’t be used to thin water-based paint, latex paint, lacquer or shellac. Its liquid and vapors are flammable. Breathing in turpentine can hurt the respiratory and central nervous system.
• Denatured alcohol: This solvent is made of drinking alcohol (ethanol) that has been altered with other chemicals. It works well for thinning shellac, lacquer, resin and ink. Denatured alcohol is also good for cleaning paint brushes and removing glue. Consuming denatured alcohol can be fatal.
• Linseed oil: Also known as flaxseed oil, this oil can improve the flow of oil-based paints. It can also be used to clean paint brushes and as a finish for wood furniture. With rags that have been used with linseed oil, there is a risk of spontaneous combustion. To prevent fire, when temperatures are above 40 degrees F dry any rags outside for at least 24 hours.
• Acetone: Often the main component in nail polish remover, acetone can be used to thin paint and lacquer and to remove adhesive, epoxy and ink. Acetone can also be used as a paint stripper and to clean up after projects. In both liquid and gas forms, acetone is highly flammable. It can also cause eye and lung irritation, dizziness and drowsiness.
• Methyl Ethyl Keytone (MEK): Also known as butanone, MEK is often used to wipe down surfaces before new paint or stain is added. It can be used to remove paint, adhesive, epoxy, grease and dirt.
• Xylene: This solvent can be used to thin oil-based paint, enamel, varnish and adhesive. Its liquid and vapor are flammable.
• Lacquer thinner: This solvent can be used to clean brushes, paint sprayers and other equipment after working with lacquer. In liquid and vapor forms, it is highly flammable.

Tip: Wondering about paint thinner vs. acetone? Acetone can be used to take old paint off a surface. However, if you combine acetone with new paint, the paint will no longer be usable.

Paint Stripper Tools and Application

You can use paint brushes, putty knives and paint brushes to apply paint solvent or removers. Once your paint solvent has taken effect, use dull putty knives, synthetic scrub pads and scrapers to take off the paint or finish. Here are some other tools and techniques to use when stripping paint:

• To remove finish from hard-to-reach nooks and crannies, place some wood shavings in your gloved hand. Wrap your hand around table or chair legs and rub them down.
• Rope can be useful for getting into cracks and turnings.
• If the remover creates a waxy buildup, make sure it’s thoroughly removed before refinishing.
• For a chemical-free option, heat guns can be used to remove paint. Once heated, simply use a scraper or putty knife to remove the finish.

Tip: To apply removers, use inexpensive, disposable brushes so you can throw them away after use.

Paint Stripper Safety

Make safety a priority when using all types of solvents and strippers. This is particularly when working with flammable materials or substances that emit toxic fumes. Plus, prolonged exposure to paint strippers has been linked a range of health problems. Read the manufacturer’s warnings and carefully follow the safety precautions on the label. Always use safety gear to protect yourself against the toxic chemicals and fumes.

• Protect your body by wearing pants, a long-sleeve shirt, gloves and an apron.
• Safety glasses or splash-proof goggles will keep your eyes safe while a respirator will help protect your respiratory system.
• Even if you're wearing a respirator, make sure you're working in a well-ventilated area. When you’re stripping paint, work outside whenever possible.
• Wear a face shield when working with caustic removers, such as lye.
• Roll chemical-resistant gloves over your sleeves to prevent drips from running down your arm.
• If you’re uncomfortable with the potential negative health effects that paint strippers can cause, consider hiring someone to do the work.

Safety Tip: If you have any old paint removers that are labeled “non-methylene,” dispose of them properly. Do not use them for your projects. Methylene chloride is a hazardous chemical that has been banned because it is connected to cancer, heart attacks and other serious health issues.

The Dangers of Traditional Paint Strippers

Paint strippers work by penetrating the paint layer and weakening the bond between the paint and the underlying surface, making it easier to scrape or wash away. For many years, the most effective paint strippers contained methylene chloride (also known as dichloromethane or DCM). While fast-acting, these products pose significant health risks due to their harsh fumes and high volatile organic compound (VOC) content. Exposure to methylene chloride can cause dizziness, nausea, and, in severe cases, unconsciousness or even death. These chemicals are also harmful to the environment.

Paint Strippers: The Need for Safer Alternatives

The health and environmental risks associated with traditional paint strippers have led to a growing demand for safer alternatives. These new formulations aim to provide effective paint removal without the dangers posed by methylene chloride and other harsh chemicals. As interest in green building practices has increased, so has the availability and popularity of these safer options.

Types of Safe Paint Strippers

There are several safe paint strippers on the market you can use for your home improvement project. 

Citrus-Based Strippers

Citrus-based paint strippers use natural citrus terpenes, typically derived from oranges, as their active ingredient. These products offer a pleasant citrus scent and are biodegradable, making them an environmentally friendly choice.

One popular citrus-based option is Citristrip. This gel formula works well on vertical surfaces like chair and table legs. It uses N-methylpyrrolidone (NMP) as its active stripping ingredient instead of methylene chloride. Citristrip can be left on surfaces for 30 minutes up to 24 hours to remove layers of latex or oil-based paints from wood, metal, and masonry.

Soy-Based Strippers

Soy-based paint strippers rely on soy esters to break down paint and other finishes. These products are known for their mild odor and eco-friendly properties.

Dibasic Ester Strippers

Dibasic ester strippers use gentler chemicals to remove paint without the harsh effects of traditional formulas. These products are often mild enough to be rinsed down the drain after use.

How To Choose a Safe Paint Stripper

To pick the best paint stripper for your project, consider factors like surface material and type of paint or finish:

• Dwell time: Consider how long you’re willing to let the stripper work before removal.
• Environmental impact: Look for biodegradable and eco-friendly options if this is a priority for you.
• Indoor or outdoor use: Choose a product suitable for your working environment.
• Surface material: Make sure the stripper is compatible with the surface you’re working on (wood, metal, masonry, etc.).
• Type of paint or finish: Some strippers work better on certain types of paints or finishes.

Carefully read paint stripper product labels to understand the following:

• Active ingredients: Look for safer alternatives to methylene chloride.
• Application instructions: Understand how to apply the product correctly.

Application

Now, it’s time to apply your paint stripper. Follow these steps: 

1. Apply a thick, even layer of stripper using a brush or roller.
2. Allow the stripper to dwell for the recommended time, which may be longer than traditional strippers.
3. Test a small area to see if the paint is ready to be removed.
4. If needed, cover the area with plastic wrap to prevent the stripper from drying out during longer dwell times.

Removal and Clean-Up

Once you’ve applied your paint stripper, take the following steps to remove it and clean up: 

1. Use a plastic scraper to remove loosened paint, working in the direction of the wood grain on wooden surfaces.
2. Clean the surface according to the product instructions, which may involve water or a specific neutralizing solution.
3. Allow the surface to dry completely before refinishing.
4. Dispose of stripped paint and used materials according to local regulations.

Indoor vs. Outdoor Use of Safe Paint Strippers

While safe paint strippers are generally less toxic than traditional formulas, it’s important to factor in indoor versus outdoor use.

Safe Indoor Options

For indoor use, choose products specifically labeled as safe for indoor applications. These typically have lower VOC content and milder odors. Citristrip is typically suitable for indoor use with proper ventilation. Always open windows and use fans to circulate air, even with safer products.

Best Practices for Outdoor Stripping

Here are a few tips if you’re stripping paint outdoors:

• Be aware of wind direction to avoid spreading fumes or debris.
• Choose a day with mild weather conditions.
• Have a plan for proper disposal of stripped paint and used materials.
• Use drop cloths to catch paint chips and prevent soil contamination.
• Work in a well-ventilated area away from plants and animals.

Safety Precautions When Using Paint Strippers

Even when using safer paint strippers, you should follow safety precautions to protect yourself and the environment.

Personal Protective Equipment

Always wear the following:

• Chemical-resistant gloves
• Long-sleeved clothing and closed-toe shoes
• A respirator, if recommended by the product manufacturer
• Safety goggles or glasses

Ventilation Requirements

Proper ventilation is essential when using any paint stripper. Work outdoors when possible, or open all windows and doors when working inside. Use fans to circulate air and remove fumes. Take frequent breaks in fresh air.

Proper Disposal Methods

Dispose of paint strippers and stripped paint responsibly. Check local regulations for proper disposal methods and use a hazardous waste disposal facility if needed. Never pour paint strippers down the drain or into the ground (unless specifically recommended by the product label), and allow paint chips to dry completely before disposal.

Comparing Safe Paint Strippers to Traditional Methods

When considering safe paint strippers versus traditional methods, weigh the following factors.

Effectiveness

Safe paint strippers can be as effective as traditional methods, but they often require longer dwell times. For example, Citristrip may need to be left on for up to 24 hours to remove multiple layers, while methylene chloride strippers typically work faster. However, the trade-off in time is often worth the reduced health and environmental risks.

Time and Effort Required

Safe paint strippers generally require more time and patience. You may need to wait longer for paint to strip, and you could need multiple applications to remove stubborn layers. Gentler formulas may also require more scraping effort.

Cost

Safe paint strippers are typically priced similarly to traditional products. While the initial cost may be comparable, safe strippers may require larger quantities for the same job due to longer dwell times and potential reapplications.

Safe Paint Strippers: Our Conclusion

Safe paint strippers offer a viable alternative to traditional, harsh chemical formulas. While they may require more time and patience, the benefits to personal health and environmental safety make them an excellent choice for most paint-stripping projects.
