What You'll Learn
Prepare your work area and protect yourself
Before you begin stripping the paint off your chair, it is important to prepare your work area and take the necessary safety precautions to protect yourself. Here are some detailed steps to guide you through the process:
Choose a suitable workspace
Select a workspace that is well-ventilated to minimise the inhalation of toxic fumes. If working indoors, cover air vents to prevent dust and debris from circulating to other areas of your home. It is also important to ensure that your workspace is clean and free from any clutter that could interfere with your work.
Cover and protect surrounding areas
Use plastic sheeting to cover the floor and any nearby furniture or items that you do not want to get paint on. Extend the sheeting at least 6 feet beyond your work area and overlap and tape the edges to secure it in place. Cover the plastic sheeting with a layer of newspaper or contractor's paper to provide extra protection and help absorb spills.
Wear protective gear
It is crucial to wear the appropriate safety gear to protect yourself from the chemicals and debris involved in paint stripping. This includes heavy-duty gloves, a respirator or mask, safety goggles or glasses, and old clothing that you don't mind getting dirty. These measures will help safeguard your skin, eyes, and respiratory system from potential irritation or harm.
Remove or cover nearby items
Any items that are not being stripped of paint, such as knobs, pulls, or hinges, should be removed if possible. If there are items that cannot be removed, such as upholstery, cover them with heavy plastic sheeting and secure them with painter's tape. This will help prevent accidental paint stripping or damage to these areas.
Gather the necessary tools and materials
Before you begin, ensure that you have all the tools and materials you need within easy reach. This includes your chosen paint stripper, scrapers, brushes, sandpaper, and any other specific items recommended by the manufacturer of your chosen paint stripper. Having everything ready beforehand will make the process more efficient and help avoid interruptions during the stripping process.
Read and follow safety instructions
Different paint strippers may have specific safety instructions, so it is important to read and follow the directions provided by the manufacturer. Pay close attention to warnings, precautions, and recommended safety gear to ensure that you are adequately protected during the paint stripping process. Some chemicals can be extremely dangerous, so taking the necessary safety measures is crucial.

Choose a paint stripper
When choosing a paint stripper, it is important to consider the type of surface you are working with, the number of paint layers, and any safety precautions. Here are some options for paint strippers that can effectively remove three layers of paint from a chair:
Citrus-based Strippers
Citrus-based strippers, such as Citristrip, use natural citrus terpenes derived from oranges as their active ingredient. They offer a pleasant scent and are biodegradable, making them environmentally friendly. This type of stripper is effective on vertical surfaces like chair legs and can remove multiple layers of latex or oil-based paints from wood, metal, and masonry. Citristrip can be left on the surface for up to 24 hours, depending on the number of paint layers.
Biochemical and Non-toxic Strippers
Biochemical and non-toxic strippers are made with plant-based solvents and are considered safer alternatives to caustic and solvent-based products. They can take longer to work, typically between 4 and 24 hours, but they are effective on wood, metal, and masonry. These strippers can remove up to seven layers of paint, including water-based and oil-based paints. However, they may not be suitable for removing epoxy or polyurethane coatings.
Max Strip
Max Strip is an all-purpose remover that is effective on various surfaces, including metal. It works quickly, typically within 15 minutes to 3 hours, depending on the number of paint layers. Max Strip does not produce harsh fumes or odors and can be rinsed away with water. It is easy to apply and adheres well to vertical surfaces. However, it may emit a slightly unpleasant odor, although it is not overpowering.
Chemical Strippers
Chemical strippers come in liquid, gel, or paste forms and are effective at dissolving paint. They are ideal for fine details, awkward shapes, and hard-to-reach areas. However, they can be messy, smelly, and slow. When using chemical strippers, always prioritize safety and follow the manufacturer's instructions and warnings. Some chemical strippers contain methylene chloride, which is effective but poses significant health and environmental risks.
Heat Guns
If you prefer a chemical-free option, a heat gun can be used to soften the paint, which can then be scraped off with a putty knife or scraper. Heat guns are effective on flat surfaces or tight spaces, but they produce fumes and carry a risk of charring the wood.

Apply the stripper
When applying the stripper, it is important to follow the manufacturer's instructions. Different strippers will have different application methods, strengths, and removal processes. For example, some strippers are brushed, rolled, or sprayed on, while others are applied with a chip brush. Some strippers will require a single coat, while others may require multiple coats.
CitriStrip, for instance, is an orange gel that is best used on furniture details and flat surfaces. It is applied with a chip brush, and while it can remove up to seven layers of paint, it may need to be applied multiple times. After applying, you should wait at least 30 minutes, but no more than 24 hours, before scraping off the paint with a plastic scraper. Then, use an abrasive pad and mineral spirits to remove any lingering residue.
Another option is to use a paste-like stripper such as SmartStrip, which can be brushed, rolled, or sprayed on and can remove up to 15 layers of paint. After applying, simply scrape off the paint, scrub off the residue with a wet nylon brush, and rinse with water.
If you are working with curved surfaces, such as chair spindles, you may need to get creative with your tools. Some people have suggested cutting up plastic cups or containers to create curved edges that can reach into the curves of the spindles.
It is also important to take safety precautions when working with chemical strippers. Be sure to use heavy-duty gloves, a mask or respirator, eyewear, and ensure good ventilation. Cover your work area with plastic sheeting to catch any drips or spills, and dispose of the paint scrapings properly.
Remember to be patient and allow the stripper to do its job. Depending on the type of paint, the number of layers, and the temperature of your work area, the stripper may take longer to work. Always refer to the manufacturer's instructions for specific timings.

Scrape off the paint
Scraping off the paint is a crucial step in the paint-stripping process. However, it is essential to exercise caution to avoid damaging the chair's surface. Before scraping, ensure that the paint stripper has sufficiently softened the paint. Depending on the product, this could take anywhere from 20 minutes to 24 hours. You'll know the paint is ready to be scraped when it has a bubbled appearance and a consistency similar to that of peanut butter.
When scraping, use a plastic putty knife or scraper to avoid gouging the wood. Metal scrapers can also be used, but they may require more care to prevent damage to the chair. It is recommended to start with a plastic scraper and then switch to a metal one if necessary, being careful not to apply too much pressure. Always scrape in the direction of the wood grain, and be extra gentle when working on curved or detailed areas of the chair.
If you encounter stubborn areas where the paint is difficult to remove, you can apply more paint stripper and let it sit for a while longer. You may need to repeat this process several times, especially when dealing with multiple layers of paint. After scraping, it is typical to find residual paint or a sticky residue on the chair. This can be addressed by using an abrasive pad, such as Scotch-Brite, and mineral spirits to scrub and wipe down the surface.
In some cases, you may need to scrape away small portions of the wood itself to ensure all the paint is removed, especially if the paint has soaked into the grain. This is more common when dealing with raw wood that has not been previously varnished or painted. After scraping, it is essential to neutralise the stripped surface with a suitable solution, such as MEK, to prepare it for the next steps, such as refinishing or repainting.

Clean up and sand
Clean-up and Sanding
Before you begin the clean-up, ensure you are wearing protective gear, such as heavy-duty gloves, a mask, eyewear, and other safety gear. Once the paint stripper has done its job, use a plastic scraper to gently scrape away the softened paint. You can also use a metal putty knife, but be careful not to gouge the wood. Use a plastic drop sheet or a large garbage bag to catch the scraped-off paint.
After removing the bulk of the paint, it's time to clean up any leftover residue. Use mineral spirits or a compatible solvent to scrub the surface with a toothbrush, Scotch-Brite pad, or a nylon brush. This will ensure that any remaining paint or residue is removed. If you're using a solvent, make sure to choose one that is compatible with the paint stripper you used. The right solvent will dissolve or float away the residue, while the wrong one can turn it into a gummy mess.
Once the surface is clean, it's time to sand it. Sanding will help smooth out any imperfections and create a uniform surface. Use fine-grit sandpaper or a sanding pad to gently sand the surface of the chair. Pay extra attention to any detailed or curved areas, such as spindles, and use smaller tools like a Scotch-Brite pad or a sanding pad to get into tight spaces. If you're working with curved or rounded chair legs, consider using emery cloth in a back-and-forth motion to avoid creating flat patches.
Finally, always work in a well-ventilated area or outdoors when cleaning and sanding to avoid inhaling dust or chemical fumes. Cover nearby items and surfaces to protect them from dust and debris. You can use plastic sheeting or drop cloths to catch the dust and contain the mess. Remember to take your time and be gentle during the clean-up and sanding process to avoid damaging the wood or creating scratches on the surface.
