Choosing the right paint

Type of Paint

The most suitable types of paint for hard plastic chairs are spray paint and paint specifically formulated for plastics. Spray paint is widely available and comes in a variety of colors and finishes. It is easy to apply and can provide a smooth and even finish. However, it may require multiple coats to achieve full coverage. Paint for plastics, on the other hand, is designed to adhere well to plastic surfaces and can be applied with a brush or roller. It is a good option if you prefer a traditional painting method or if you want to create unique designs or patterns.

Paint Adhesion

To ensure that your paint job lasts, it is crucial to choose a paint that adheres well to plastic. Look for paints that are specifically marketed for use on plastic surfaces or have "adhesion" or "bonding" mentioned on the label. These paints often contain additives that improve their ability to stick to smooth, non-porous surfaces like plastic.

Surface Preparation

Proper surface preparation is key to ensuring good paint adhesion. Before painting, make sure the plastic chair is clean, dry, and free of any dirt, grease, or debris. Lightly sanding the surface with fine-grit sandpaper can also help create a rougher texture, improving paint adhesion. Some paints may also require a primer to be applied before painting to enhance adhesion and durability.

Paint Finish

Consider the desired finish for your chairs when choosing a paint. Paints come in various finishes, including matte, satin, semi-gloss, and high-gloss. A matte finish can give a modern and understated look, while a high-gloss finish can provide a shiny and reflective appearance. Choose a finish that aligns with your aesthetic preferences and the overall style of the space where the chairs will be used.

Color Selection

Select a color that complements your existing decor and the purpose of the chairs. If the chairs are for outdoor use, consider choosing a color that can withstand UV rays without fading. You may also want to opt for a lighter color to reflect sunlight and keep the chairs cooler. For indoor chairs, feel free to experiment with bolder colors or choose a neutral shade that matches any surrounding color scheme.

Preparing the chair

Preparing your hard plastic chair for painting is a crucial step in ensuring a smooth and lasting finish. Here is a step-by-step guide to help you prepare your chair for a vibrant new look:

Cleaning and Drying:

Start by giving your chair a thorough cleaning to remove any dirt, dust, or grime. You can use an all-purpose cleaner or a degreaser, along with a sponge or cloth, to wipe down the chair's surface. If your chair has been outdoors for a long time or has stubborn stains, use a cleaner with ammonia to effectively remove mould or mildew. For new or less dirty plastic chairs, a simple wipe-down with a damp cloth may suffice. Once you've cleaned the chair, ensure it dries completely. You can use a towel to speed up the initial drying process, but be sure to let it air dry thoroughly before proceeding.

Sanding:

Lightly sand the entire surface of the chair to create a slightly rough texture. This step is especially important if your chair has been painted before, as it will help the new paint adhere better. Use fine-grit sandpaper or a sanding sponge, and always test your sanding material on a small, inconspicuous area first to ensure it doesn't leave visible scratches. After sanding, wipe down the chair with a tack cloth to remove any dust or debris.

Workspace Preparation:

Choose a well-ventilated workspace, preferably outdoors, to minimise the inhalation of paint fumes. Cover the floor or ground with drop cloths, old newspapers, or a tarp to protect the surrounding area from paint spray. If your chair has non-plastic components, such as metal legs, cover them with painter's tape to protect them from paint.

Priming:

Although not mandatory, priming the chair will help the paint adhere better and can be especially useful if you want to use a colour not typically available for plastics. Choose a primer designed for plastic materials and apply it with a steady back-and-forth motion, holding the can's nozzle 12-18 inches (30-45 cm) from the surface. Allow the primer to dry completely according to the manufacturer's instructions before proceeding to the painting stage.

Now that your hard plastic chair is thoroughly cleaned, dried, sanded, and primed, it is ready for painting! Remember to follow the manufacturer's instructions for the specific paint you choose and always work in a well-ventilated area.

Using primer

Before applying primer to a hard plastic chair, ensure that the chair is clean and dry. Use hot water, an all-purpose cleaner, and a sponge to thoroughly wash the chair. If the chair has been outside for a long time or has stubborn stains, use a cleaner with ammonia. Spray it down from all angles using a garden hose. Dry the chair with a towel, then let it air dry completely. If the chair has been painted before, lightly sand the surface with fine-grit sandpaper or a sanding sponge to scuff the surface and improve paint adhesion.

Once the chair is clean and dry, it's time to apply the primer. Choose an outdoor primer formulated for use on plastic, such as True Value EasyCare® Premium Décor Spray Enamel, or Rust-Oleum 2X Ultra Cover Primer. Shake the can thoroughly, then spray the entire chair, applying in a sweeping motion about 12 to 18 inches from the surface. Be sure to wear safety glasses and a dust mask to protect yourself from paint mist.

Let the primer dry for the amount of time recommended by the manufacturer. Priming the chair allows you to use any kind of spray paint, which is helpful if you want a specific colour that is not available in paints made for plastic. You can also use a paint and primer in one product, such as True Value X-O Rust Paint & Primer in One or Rust-Oleum 2X Ultra Cover Paint+Prime. These products can be applied directly to the plastic chair, saving you time and effort.

When the primer is dry, you can begin painting the chair. Choose a spray paint that is specifically designed for use on plastic, such as Rust-Oleum Seaside or Rust-Oleum Painter's Touch 2X Ultra Cover Paint. Hold the can at least 12 inches away from the surface and spray in a sweeping motion. Apply thin coats of paint, allowing each coat to dry before applying the next. The number of coats you need will depend on the chair and your personal judgment. Once you're happy with the coverage, let the chair dry for at least 24 hours before use.

Painting technique

Painting hard plastic chairs is a simple and inexpensive DIY project that can transform your outdoor space. Here is a step-by-step guide to achieving the best results:

  • Clean the chairs: Use a sponge or cloth to wash the chairs with hot water and a degreaser or all-purpose cleaner. If the chairs are very dirty or stained, use a cleaner with ammonia. Rinse thoroughly with water and allow them to air-dry completely.
  • Prepare your workspace: Choose a well-ventilated workspace, preferably outdoors. Cover the ground with drop cloths, newspapers, or a tarp to protect the surface from paint.
  • Sand the chairs (optional): If the chairs have been painted before, use fine-grit sandpaper or a sanding sponge to lightly scuff the surface. This will help the new paint adhere better. Wipe away any dust with a tack cloth after sanding.
  • Prime the chairs: Select a primer designed for use on outdoor plastic furniture. Shake the can thoroughly and spray the entire chair, maintaining a distance of 12 to 18 inches from the surface. Allow the primer to dry for the recommended time before proceeding to the next step.
  • Paint the chairs: Choose a spray paint designed for plastic, preferably with a satin finish. Hold the can about 12 inches away from the surface and apply the paint using a sweeping motion. For the best results, apply several light coats of paint, allowing adequate drying time between coats as per the manufacturer's instructions.
  • Flip the chairs: Once the tops of the chairs are dry, flip them over and apply paint to the undersides.
  • Remove painter's tape (if used): After the paint has completely dried, carefully remove any painter's tape used for creating patterns or protecting other surfaces.
  • Allow to cure: While the paint may feel dry to the touch within a few hours, it is recommended to let the chairs cure for several days to a week before using them, especially if they will be subjected to heavy use.

Drying and recoating

When you are happy with the paint coverage, it's a good idea to let the chair cure for several days to several weeks, especially if it is going to be subjected to a lot of use. This will ensure that the paint is fully hardened and will help to prevent chipping or peeling.

If you are using a paintbrush rather than a spray, you will need to allow more time for the paint to dry. The exact drying time will depend on the type of paint and the environment, but it is generally best to wait at least 24 hours before applying a second coat. As with spray paint, it is important to allow the first coat to dry thoroughly before adding another, and you may need to apply several coats to get an even finish.

Once you have finished painting and allowed the final coat to dry, it is time to remove any painter's tape that you used to protect non-plastic surfaces. Be sure to remove the tape slowly and carefully, as removing it too quickly could result in paint being pulled off the chair. If you have painted the chair outdoors, it is a good idea to bring it inside or into a covered area to protect it from the elements during the curing process.
