What You'll Learn
Use hot water, all-purpose cleaner, and a sponge
To clean plastic chairs before painting them, you can use hot water, an all-purpose cleaner, and a sponge. This method is ideal for giving your plastic chairs a thorough cleaning and preparing them for a fresh coat of paint. Here's a detailed guide to help you through the process:
Prepare the Cleaning Solution:
Start by gathering your supplies. For this method, you'll need hot water, an all-purpose cleaner, a sponge, and a bucket. Fill the bucket with hot water, and add a suitable amount of the all-purpose cleaner. The amount of cleaner you use may vary depending on the specific product, so it's always a good idea to check the instructions on the bottle. Stir the mixture well to ensure the soap or cleaner is adequately dissolved in the water.
Cleaning the Chairs:
Once you have your cleaning solution ready, it's time to start scrubbing. Dip your sponge into the bucket and squeeze out any excess liquid. Gently scrub the plastic chairs with the sponge, paying extra attention to any stained or dirty areas. If you're dealing with stubborn stains, you can also sprinkle a small amount of dry baking soda onto the sponge to create a gentle abrasive that will help lift the stains. Remember to always wash the chairs from the top down to catch any drips of dirty water.
Rinsing and Drying:
After you've scrubbed the chairs, it's important to rinse away any remaining soap or cleaning solution. You can use a garden hose to thoroughly rinse the chairs, ensuring that all soap residue is removed. Once they're rinsed, you can either dry the chairs with a microfiber towel or simply let them air dry in the sun. It's crucial to ensure that the chairs are completely dry before you start the painting process.
Additional Tips:
If your plastic chairs have been outside for an extended period or have stubborn mould or mildew stains, consider using a cleaner with ammonia for more effective stain removal. Additionally, always choose a well-ventilated workspace, preferably outdoors, when preparing to paint your plastic chairs. Cover the floor or ground with drop cloths or newspapers to catch any paint drips and protect the surrounding area.

Clean with vinegar
Vinegar is a cheap and simple way to clean plastic patio chairs before painting them. It is an effective cleaner for outdoor furniture and can be used to clean surfaces like plastic, metal, or wood.
To clean plastic chairs with vinegar, create a mixture of vinegar and water. The exact ratio of vinegar to water may vary depending on the type of dirt or stains you are trying to remove. For example, a solution of 25% water and 75% distilled white vinegar is recommended for removing mildew from white plastic chairs. On the other hand, a solution of equal parts vinegar and water can be used to wipe down metal surfaces before painting.
Mix your desired ratio of vinegar and water in a spray bottle and shake well to combine. If your plastic chairs are placed outside, spread a plastic tarp in a sunny spot and move the chairs onto it. Spray the vinegar solution onto the chairs from all angles, ensuring that all surfaces are thoroughly coated.
Let the vinegar solution sit on the chairs for a while to allow it to penetrate and loosen any dirt, stains, or mildew. The duration may vary depending on the type of dirt and the concentration of your vinegar solution. For mild cleaning, a few minutes might be sufficient, while tougher jobs may require up to 15 minutes or even longer.
After the waiting period, proceed to scrub the chairs with a sponge or a soft-bristled nylon brush. For stained areas, sprinkle a bit of dry baking soda on the sponge or brush to act as a gentle abrasive and help lift the stains. Finally, rinse the chairs thoroughly with a garden hose and allow them to air dry completely before proceeding with the painting process.

Sand the chair
Sanding a plastic chair is an important step in preparing the surface for a new coat of paint. It ensures that the paint will adhere well and creates a smooth, even finish. Here is a step-by-step guide to sanding a plastic chair:
- Select the Appropriate Sandpaper or Sanding Sponge: Choose a fine-grit sandpaper or a sanding sponge designed for use on plastic surfaces. Fine-grit sandpaper is less abrasive and will create a smoother finish, reducing the risk of visible scratches.
- Test on an Inconspicuous Area: Before starting, test the sandpaper or sanding sponge on a small, hidden area of the chair. This will help you ensure that it doesn't create irreparable scratches. If you're satisfied with the results, proceed to the next step.
- Prepare the Workspace: Sanding can create a lot of dust, so it's important to prepare your workspace. If possible, work outdoors or in a well-ventilated area. Cover any nearby surfaces or items that you want to protect from dust. If working indoors, consider using a vacuum or dust-catching attachment to minimize the spread of dust.
- Protect Yourself: Wear protective gear, including eye protection, a face mask, and gloves. This will safeguard you from the dust and debris generated during the sanding process.
- Start Sanding: Begin sanding the chair using gentle, even strokes. Follow the direction provided by the grain of the plastic, if applicable. Avoid applying too much pressure, as this can create grooves or scratches. Focus on creating a uniform, lightly scuffed surface that will be receptive to primer and paint adhesion.
- Sand Curves and Details: For curved areas or intricate details on the chair, attach sandpaper to a foam backing. This will provide the flexibility needed to sand these shapes effectively.
- Remove Dust: Once you've finished sanding, use a tack cloth or a slightly damp cloth to remove any dust or debris from the chair's surface. Ensure that the chair is completely free of dust before proceeding to the next steps of priming and painting.
Remember, the key to successful sanding is taking your time and working slowly. By following these steps, you will effectively prepare your plastic chair for painting, ensuring a smooth and durable finish.

Prime the chair
Once your plastic chair is thoroughly cleaned and dried, it's time to prime! Priming your chair will allow you to use any kind of spray paint, which is helpful if you want a specific colour that isn't available in plastic-specific paints. Choose an outdoor primer formulated for use on plastic, such as True Value EasyCare® Premium Décor Spray Enamel. Before you begin, shake the can thoroughly.
Now, it's time to start spraying! Hold the can about 12 to 18 inches away from the chair and spray in a sweeping motion. Be sure to wear safety glasses and a dust mask to protect yourself from the paint mist. Cover all the areas of the chair that you plan to paint. If your chair has non-plastic parts, such as metal legs, make sure to cover them with painter's tape before priming.
Let the primer dry completely before moving on to painting. Follow the instructions on the primer packaging for the recommended drying time. A thorough drying will ensure that your paint job adheres well to the chair.
If you're short on time or prefer a simpler approach, consider using a paint and primer in one product, such as True Value X-O Rust Paint & Primer in One. This option eliminates the need for a separate priming step, streamlining the process.

Choose a paint
When it comes to choosing paint for your plastic chairs, there are a few things to consider. Firstly, if your chairs are intended for outdoor use, it is important to select a paint that is specifically designed for outdoor plastic surfaces. This will ensure that the paint can withstand the elements and provide a durable finish. You can find these paints at your local home improvement store or online.
Another factor to consider is the type of paint you want to use. Spray paint is a popular choice for plastic chairs as it is easy to apply and can provide a smooth, even finish. It is also a budget-friendly option, as you can often find spray paints that include both the primer and paint in one can, reducing the number of steps and products needed. When selecting a spray paint, opt for one with a satin finish, as this is recommended for plastic surfaces. You can also choose between a matte or gloss finish for your topcoat, depending on your desired look.
If you prefer to use a brush to apply your paint, you can choose between a synthetic brush or a bristle brush. If you opt for a bristle brush, remember to soak it in water overnight before use. This will help the brush absorb the paint better and provide a smoother finish.
It is also important to consider the colour of your paint. If you are painting multiple chairs, it may be a good idea to test the paint on one chair first to ensure that you are happy with the colour and that the paint adheres well to the surface. This will save you time and money in the long run. You can also ask for a sample portion of your desired colour at your local hardware store, which should be enough to cover one plastic chair.
Lastly, don't forget to purchase a primer if your chosen paint does not include it. A primer will help the paint adhere better to the plastic surface and will allow you to use any colour of paint, even those not specifically designed for plastic. Look for a primer that is designed for outdoor plastic surfaces and apply it using a spray can, following the manufacturer's instructions.
