Choosing the right paint

Type of Paint

It is crucial to select a paint specifically designed for use on plastic surfaces. This ensures that the paint will adhere properly to the plastic material of the chairs. Look for spray paints that are formulated to bond with plastic, such as Rust-Oleum 2X Ultra Cover, which is suitable for plastic, wood, and metal surfaces.

Primer

Priming the chairs before painting is an important step to ensure better paint adhesion and a more durable finish. You can choose to apply a separate primer formulated for plastic surfaces or opt for a paint-and-primer-in-one product, such as Rust-Oleum Painter's Touch 2X Ultra Cover, to streamline the process.

Finish

The desired finish of your chairs will influence your paint choice. Satin finishes are often recommended for plastic chairs as they provide a more durable and aesthetically pleasing result compared to gloss finishes. A satin finish will give your chairs a subtle shine without being too glossy or reflective.

Colour

When choosing a colour, consider the environment in which the chairs will be placed and your personal preference. Bright and vibrant colours can add a punchy accent to your outdoor space, while more subdued colours can create a calm and relaxing atmosphere. If you're looking for colour inspiration, Rust-Oleum offers a range of colours like Seaside, Lagoon, Key Lime, and Brilliant Blue.

Number of Coats

Consider the coverage and number of coats required by the paint. Some paints may require multiple thin coats, while others may provide full coverage in just one or two coats. Additionally, take into account the drying time between coats as specified by the manufacturer to ensure a smooth and even finish.

By considering these factors, you can make an informed decision when choosing the right paint for spray painting white plastic chairs, ensuring a successful and satisfying DIY project.

Preparing the chair

Preparing your white plastic chairs for spray painting is a crucial step in achieving a smooth and lasting finish. Here is a step-by-step guide to help you get started:

Cleaning and Drying:

Start by thoroughly cleaning your chairs. Use hot water, an all-purpose cleaner, and a sponge to remove any dirt, dust, or grime. If your chairs have been outdoors for an extended period or have stubborn stains, consider using a cleaner with ammonia. Spray them down from all angles with a garden hose to ensure no residue is left behind. You can also use a wire brush or a metal brush to remove any flaky or loose paint. Once they are clean, dry each chair with a towel and let them air dry completely. This step is essential, as dirt and water are the "enemies of spray paint," and can affect the adhesion of the paint.

Workspace Preparation:

Choose a suitable workspace that has plenty of ventilation. Outdoors is ideal, but if you must work indoors, ensure the area is well-ventilated. Cover the floor or ground with drop cloths or newspapers to protect the surrounding area from paint.

Sanding:

Lightly sand the chairs with fine-grit sandpaper or a sanding sponge. This process creates a rough surface, which helps the paint adhere better. It also removes any existing paint or primer and can smooth out any imperfections. After sanding, wipe down the chairs again to remove any dust or debris created during the sanding process.

Covering Non-Plastic Surfaces:

If your chairs have any non-plastic components, such as metal legs, cover them with painter's tape to protect them from paint. This will help you achieve a neat and precise finish.

Primer Application:

Although not mandatory, using a primer specifically formulated for plastic, such as True Value EasyCare® Premium Décor Spray Enamel, can improve paint adhesion and allow you to use any type of spray paint. Shake the can thoroughly, then spray the entire chair, maintaining a distance of about 12 to 18 inches from the surface. Be sure to wear safety glasses and a dust mask during this step. Allow the primer to dry completely according to the manufacturer's instructions before moving on to painting.

Practice and Testing:

Before you begin painting, it is a good idea to practice your spraying technique. You can try spraying on the bottom side of the chair or any leftover cardboard or newspaper to get a feel for the rhythm and motion of spraying. This will help you achieve better results when you start painting the visible surfaces.

Painting technique

First, ensure you are working in a well-ventilated area, preferably outside, and cover the floor with drop cloths or newspapers. Protect any non-plastic surfaces, such as metal legs, with painter's tape.

Before painting, clean the chairs thoroughly with hot water, an all-purpose cleaner, and a sponge. For stubborn stains or mould, use a cleaner with ammonia. Rinse with a garden hose and dry with a towel, then let the chairs air-dry completely.

Some chairs may require light sanding to scuff the surface and help the paint adhere better. Use fine-grit sandpaper or a sanding sponge to lightly sand the entire surface to be painted. Wash the chairs again to remove any dust, then let them dry completely.

When you're ready to paint, shake the can thoroughly. Hold the can about 10-18 inches from the surface of the chair and keep the can moving while you spray, using a sweeping motion. Apply a thin coat of paint, and don't worry about full coverage during this first coat. You can practice on the bottom side of the chair to get a feel for the rhythm. Let the first coat dry for about 30 minutes to an hour, or as recommended by the manufacturer, then apply a second coat.

For the best results, use a spray paint specifically designed to adhere to plastic. You can also use a primer formulated for use on plastic, or choose a paint that includes a primer for better adhesion. A satin finish is ideal for plastic chairs.

Drying and curing

After washing and preparing your plastic chairs, it is important to let them dry thoroughly before moving on to the painting stage. Use a towel to dry each chair, then let them air-dry completely. This step is crucial, as any remaining moisture can affect the adhesion of the paint.

Once the chairs are dry, you can begin the painting process. If you are using a primer, follow the instructions on the packaging for drying times. Typically, primers will need to dry for the recommended amount of time before you can apply the first coat of paint. This can range from 30 minutes to a few hours, depending on the product and environmental conditions.

When applying the paint, hold the can about 10 to 18 inches away from the surface of the chair and use a sweeping motion. Don't worry about full coverage with the first coat. You can let the first coat dry for about 30 minutes before applying a second coat for a more even and consistent finish.

After you have applied the final coat of paint, let the chairs dry for a few hours in a warm, dry place. Avoid touching or sitting on the chairs during this time to prevent any smudges or imperfections. The paint will continue to cure and harden over the next few days, so it is recommended to wait a few days before using the chairs regularly.

The curing process is just as important as the painting process. It allows the paint to fully harden and bond with the plastic surface. This will ensure that your paint job is long-lasting and durable. The curing time can vary depending on the type of paint used and the environmental conditions, such as temperature and humidity. Always refer to the manufacturer's instructions on the paint can for specific curing times and recommendations.

Aftercare

Once you have spray-painted your white plastic chairs, you will want to ensure that your hard work is preserved and that the paint job lasts for a long time. Here are some aftercare tips to help you maintain the quality of your freshly painted chairs:

Allow for Drying Time

After you have finished painting, it is important to let the paint dry completely. Depending on the type of paint used and the number of coats applied, this could take anywhere from 30 minutes to a few hours or even a few days before anyone sits on the chairs. It is recommended to let the chairs dry in a warm, well-ventilated area.

Apply a Protective Top Coat

Consider sealing your chairs with a protective top coat, especially if they will be exposed to outdoor weather conditions. Choose a product specifically formulated for plastic surfaces, such as a coat of sealant or polyurethane, to enhance the durability of the paint and protect it from the elements.

Regular Cleaning and Maintenance

Regularly clean your painted chairs to maintain their appearance and prolong the life of the paint. Use a mild soap or detergent and a soft cloth or sponge to wipe down the surfaces gently. Avoid using abrasive cleaning tools or harsh chemicals that may damage the paint. For more stubborn stains or build-ups, a gentle all-purpose cleaner or a cleaner with ammonia can be used.

Touch-Ups and Repainting

Over time, the paint on your chairs may start to show signs of wear and tear. If you notice any chips, scratches, or fading, you may need to perform touch-ups or repaint the chairs entirely. Before repainting, ensure the chairs are clean and dry, and follow the same preparation steps as before, including light sanding if necessary. You can then apply a fresh coat of paint, following the manufacturer's instructions for the best results.

Storage and Protection

If you plan to store your chairs for an extended period or during harsh weather conditions, consider bringing them indoors or providing some form of protection. Storing the chairs in a dry, covered space can help shield them from excessive sun exposure, rain, or extreme temperatures, all of which can impact the condition of the paint over time.

Frequently asked questions

First, clean your chairs with hot water and an all-purpose cleaner, or a hose and a degreasing product. If the chairs have been outside for a long time, use a cleaner with ammonia. Next, lightly sand the chairs with fine-grit sandpaper or a sanding sponge to scuff up the surface and help the paint stick. Then, wash the chairs again to remove any dust and let them dry completely. Choose a workspace with good ventilation and cover any non-plastic surfaces with painter's tape and the floor with drop cloths or newspapers. When you're ready to paint, hold the can about 10-18 inches from the surface of the chair and keep the can moving while you spray. Apply a few light, even coats of paint, allowing each coat to dry for about 30 minutes.

You should use a spray paint that is specifically formulated to stick to plastic. Some recommended brands include Rust-Oleum, Krylon, and True Value. You can also use a paint and primer in one, such as True Value X-O Rust Paint & Primer in One or Rust-Oleum 2X Ultra Cover.

This will depend on the type of chair you are painting and the amount of coverage you need. Most sources recommend using one can of paint per chair. However, if your chair is particularly large or has a lot of porous sections, you may need more than one can.
