What You'll Learn
Use a chemical paint remover like Krud Kutter or Citrus Strip
If you want to remove paint from plastic chairs, you can use a chemical paint remover like Krud Kutter or Citrus Strip. Both products are effective at removing paint from a range of surfaces.
Krud Kutter is a popular and powerful cleaner that can be used to remove paint from plastic chairs. It is available at Wal-Mart, Home Depot, and other similar stores. While it is a no-rinse formula, some users have reported that it can leave a residue, so it is recommended to wipe the surface with a damp cloth after using it. Krud Kutter contains alcohol, which can be an issue for water-based paints, so be sure to test it on a small area first.
To use Krud Kutter, follow these steps:
- Apply the product generously to the painted areas of the chair.
- Allow the product to sit for a few minutes to give it time to break down the paint.
- Use a scraper or putty knife to gently remove the softened paint.
- If necessary, reapply the product and repeat the process until all the paint is removed.
- Wipe down the chair with a damp cloth to remove any remaining residue.
Citristrip is another effective chemical paint remover that can be used on plastic chairs. It is a safer alternative to some other paint strippers as it does not contain harsh fumes. It is effective on multiple layers of dried latex and oil-based paints and can be used on a variety of surfaces, including wood, metal, and masonry. Citristrip is available at Home Depot and other home improvement stores.
To use Citristrip, follow these steps:
- Test the product on an inconspicuous area of the chair first to ensure it does not damage the plastic.
- Apply a generous amount of the gel to the painted areas of the chair.
- Allow the product to sit for a few minutes to activate and start breaking down the paint.
- Use a scraper or putty knife to gently remove the softened paint.
- Repeat the process as needed until all the paint is removed.
- Clean the chair with a damp cloth to remove any remaining residue.
Both Krud Kutter and Citristrip are effective options for removing paint from plastic chairs. Be sure to work in a well-ventilated area and wear protective gear, such as gloves and eye protection, when using any chemical paint removers.

Sand the chair to scuff the surface and aid paint adhesion
Sanding is an important step in preparing a plastic chair for painting. It helps create a long-lasting and durable finish. When sanding, you don't need to apply too much pressure. Just sand lightly and quickly to scuff the surface and create a dull finish. This will help the new paint adhere better to the surface.
There are various tools you can use to sand a plastic chair. If you're sanding by hand, a sanding block, sponge, or pad is a good option. Foam sanding sponges are effective and softer on the edges than paper sponges. You can also use sandpaper, such as 220-grit sandpaper, which is a good balance between being too rough and too soft. This grit will not leave deep scratches and is suitable for most furniture painting projects. If you're sanding a large, flat-surfaced piece of furniture, you can also use an electric sander with 220-grit sandpaper. However, be cautious not to sand for too long in one spot, as you don't want to damage the surface.
Before you start sanding, it's important to properly prepare the chair. This includes cleaning the chair to remove any dirt, grease, or oil. Additionally, you may need to remove any hardware, such as hinges, screws, or staples, that could get in the way of the sanding process. Once you've finished sanding, be sure to wipe down the chair to remove any dust or residue.

Wash the chair with hot water, an all-purpose cleaner and a sponge
To remove paint from plastic chairs, you'll need to wash the chair with hot water, an all-purpose cleaner, and a sponge. This process will help to remove any dirt, dust, or debris from the surface of the chair, preparing it for paint removal or a new coat of paint.
- Gather your supplies: hot water, an all-purpose cleaner, and a sponge. You may also want to wear protective gloves to keep your hands dry and safe from any chemicals in the cleaner.
- Mix a solution of hot water and the all-purpose cleaner. Follow the instructions on the cleaner's packaging for the appropriate mixing ratio. Be sure to use hot water, as this will help to loosen any stubborn dirt and paint residue.
- Dip your sponge into the mixed solution and squeeze out any excess. You want the sponge to be damp, not dripping wet.
- Start scrubbing the plastic chair with the sponge. Apply gentle pressure and work your way across the entire surface of the chair. Pay close attention to any crevices or detailed areas that may require more careful scrubbing.
- Rinse the sponge frequently in clean hot water to avoid transferring dirt back onto the chair's surface. Change your cleaning solution if it becomes too dirty or if you notice paint residue building up on the sponge.
- For stubborn stains or paint residue, you can apply an all-purpose cleaner directly to the stain and let it sit for a few minutes before scrubbing again. Alternatively, you can use a cleaner with ammonia, especially if you're dealing with mould or mildew stains.
- Once you've finished scrubbing, give the chair a final rinse with clean hot water to remove any remaining residue from the cleaning process.
- Dry the chair thoroughly with a towel. Make sure to get into any crevices or detailed areas that may retain moisture.
- Finally, let the chair air-dry completely before proceeding with any paint removal techniques or repainting.
By following these steps, you'll effectively remove any dirt, paint residue, or stains from the plastic chair, preparing it for further treatment or a fresh new coat of paint.

Use a paint stripper like Odorless Mineral Spirits to remove wax
If your plastic chair has been painted with wax, a paint stripper like Odorless Mineral Spirits can be used to remove it. Odorless Mineral Spirits is a petroleum-based solvent that is highly refined to remove odor-causing compounds. While it is not completely odorless, it has a much more tolerable smell compared to regular paint thinner. It is also less toxic, making it a popular choice for DIY enthusiasts.
To use Odorless Mineral Spirits effectively, follow these steps:
- Prepare your workspace by ensuring adequate ventilation, preferably working outdoors or in a well-ventilated area. Spread drop cloths or newspapers on the floor to protect the surface from any spills.
- Put on safety gear, including gloves and eye protection, to safeguard yourself from the chemicals.
- Apply the Odorless Mineral Spirits to a clean cloth or sponge. The amount you use will depend on the size of the painted area and the thickness of the wax. As a starting point, you can mix 4 ounces of Odorless Mineral Spirits per gallon, gradually increasing the amount if needed.
- Working in small sections, apply the soaked cloth or sponge to the painted surface of the plastic chair. Let the solvent sit for a few minutes to penetrate the wax.
- Start wiping or gently scrubbing the wax in the direction of the plastic's grain. You can use a soft-bristled brush or a scrubbing pad to assist in breaking down the wax.
- Continue working in small areas until you have removed the wax from the entire chair.
- Once the wax is removed, wipe down the chair with a clean, damp cloth to remove any residual Odorless Mineral Spirits.
- Allow the chair to air dry completely before considering re-painting or re-finishing.
It is important to note that while Odorless Mineral Spirits can effectively remove wax, it may not be strong enough for all types of paint. If the chair has been painted with a thick layer of paint or a particularly durable paint, you may need to consider using a stronger paint stripper designed specifically for paint removal. Always read the instructions on the product label and take the necessary safety precautions when working with chemicals.

Apply a new coat of paint using a spray can
Painting your plastic chairs with a spray can is a simple and inexpensive way to renew and brighten them up. Here is a step-by-step guide to achieving the best results:
Prepare the Workspace:
Choose a well-ventilated workspace, preferably outside, and cover the floor or ground with drop cloths or newspapers. Gather your supplies, including the spray paint, primer, safety gear, and cleaning materials.
Clean the Chairs:
Thoroughly clean the plastic chairs using hot water, an all-purpose cleaner, and a sponge. For stubborn stains or mould, use a cleaner with ammonia. Spray the chairs with a garden hose from all angles to ensure a thorough rinse. Dry each chair with a towel, then let them air dry completely.
Sand the Chairs:
Lightly sand the chairs to create a scuffed surface, which will help the new paint adhere better. Sanding also helps remove any powder or residue on the surface of the chairs. After sanding, wash down the chairs again to remove any dust and let them dry completely.
Prime the Chairs:
Apply a primer specifically designed for plastic surfaces, such as Valspar Outdoor Primer for Plastic. Follow the instructions on the packaging, and let the primer dry completely before moving on to the next step. Priming allows you to use any type of spray paint and colour of your choice.
Paint the Chairs:
Now it's time to apply the new coat of paint using a spray can. Hold the can at least 12 inches away from the surface of the chair and spray in a sweeping motion. Apply thin and light coats of paint, allowing each coat to dry before applying the next. The number of coats will depend on your desired coverage and the furniture's condition. Remember to flip the chairs upside down to paint the bottom first, and you don't need to completely cover the underside.
Let the Paint Dry:
Once you are happy with the paint coverage, let the chairs dry for at least 24 hours before using them. This will ensure that the paint is completely cured and ready for use.
