Plastic outdoor furniture is a durable option that can withstand the erratic climate of sun, rain, and temperature swings. However, exposure to sunlight can cause fading and degradation over time. To refinish plastic outdoor furniture, there are several methods you can employ to restore its appearance. Firstly, it is crucial to clean the furniture to remove any dirt, grime, mould, or mildew. This can be done with a mild soap solution, or for heavily soiled furniture, baking soda or vinegar can be used. Once the furniture is clean and dry, you can choose to apply a plastic restorer, such as WD-40, or use a fine-grit sandpaper to roughen the surface and allow for better paint adhesion. If painting, it is recommended to use a primer designed for plastic surfaces, followed by a high-quality outdoor spray paint formulated for plastic. Alternatively, you can use a heat gun on a low setting to improve the appearance of the plastic, but this method is more complex and requires caution to avoid damaging the furniture. Regular maintenance, including cleaning and applying a protective coating, will help prolong the life of your refinished plastic outdoor furniture.

Clean the furniture
Before refinishing your plastic outdoor furniture, it is important to clean it thoroughly. This will ensure that any treatments or paints you apply will adhere properly, and help to extend the lifespan of your furniture.
Start by removing any loose debris, such as cobwebs, dirt, or leaves, from the surface of the furniture. You can do this by wiping the furniture down with a damp cloth or using a soft-bristled brush or sponge. If your furniture is particularly dirty, you can sprinkle baking soda directly onto a damp sponge or cloth and scrub the surface. Alternatively, you can use a mild household abrasive or an ammonia-based cleaner to remove any stubborn dirt or grime.
Once the surface is free of debris, you may need to remove any mould, mildew, or stains. You can do this by applying a mixture of equal parts white vinegar and water directly to the affected areas. Allow the solution to sit for a few minutes, then wash it down with a sponge or brush and some warm, soapy water. For more stubborn stains, you can make a paste from baking soda and water and apply it directly to the stain. Leave the paste to sit and fizz, then gently scrub it with a sponge or soft-bristled brush.
If your furniture has become faded or discoloured due to sun exposure, you can use a plastic restorer, such as WD-40, to restore its appearance. Spray the product onto the surface of the furniture and rub it in with a clean, dry cloth. Wipe away any excess product before it dries.
Finally, rinse the furniture thoroughly with a garden hose, making sure to spray every surface from multiple angles to ensure a complete rinse. If you plan to paint the furniture, allow it to air dry completely before proceeding.

Sand the surface
Sanding the surface of plastic outdoor furniture is an important step in refinishing it. It helps to create a rough surface for the paint and primer to adhere to. Here's a step-by-step guide to sanding the surface of your plastic outdoor furniture:
Start by choosing the right sanding material. You can use fine-grit sandpaper or a sanding sponge designed for sanding plastic surfaces. If the furniture has been painted before, it is necessary to sand it lightly to remove any old paint. Test your sanding material on a small, inconspicuous area first to ensure it doesn't scratch the surface. If visible scratches appear, reduce the pressure or use a finer grit.
Remove any cushions or removable parts from the furniture to make the sanding process easier and to ensure you can thoroughly sand the entire piece.
Gently sand the entire surface of the furniture with your chosen sanding material. Use a light touch and work in the direction of the grain if the furniture has a noticeable grain pattern. If the furniture doesn't have a noticeable grain, work in small sections to ensure you don't miss any spots.
Pay extra attention to areas that are particularly worn or damaged. You may need to apply a little more pressure or use a slightly coarser grit in these areas to ensure the surface is evenly sanded.
Once you've finished sanding, wipe down the furniture with a damp cloth to remove any dust or debris created during the sanding process. This will ensure that the surface is clean and ready for the next step in the refinishing process, which is usually applying a primer designed for plastic surfaces.
By following these steps, you'll create a slightly roughened surface that will help the primer and paint adhere properly, resulting in a smooth and durable finish on your refinished plastic outdoor furniture.

Apply primer
Before applying primer, it is important to prepare the plastic outdoor furniture surface. Start by cleaning the furniture using a combination of hot water and an ammonia-based cleaner to remove any dirt and mildew. Once the furniture is clean and rinsed, use fine-grit sandpaper to sand the surface. This step helps to roughen the surface, allowing for better adhesion of the primer and paint. It is recommended to test the sanding material on an inconspicuous spot to ensure it does not scratch the plastic. Cover any surfaces you do not wish to paint with painter's tape.
Now, you are ready to apply the primer. Choose a primer specifically designed for plastic materials that will be stored outdoors. These primers are readily available at your local home improvement store and typically come in spray cans. Before applying, ensure you are in a well-ventilated area or consider wearing a respiratory mask to protect yourself from harmful fumes. Shake the can well and hold it about 12-18 inches (30-45 cm) away from the surface of the furniture. Spray the primer in a steady back-and-forth motion, ensuring you cover the entire surface you intend to paint.
Allow the primer to dry completely before moving on to the next step, which is applying the paint. The primer will help ensure better coverage and adhesion of the paint, giving your refinished plastic outdoor furniture a smooth and professional finish.

Paint the furniture
Painting plastic outdoor furniture is a simple and effective way to restore it and make it look new again. Before painting, ensure that the area is well-ventilated and that any surfaces are covered with newspaper or a tarp to protect them from paint.
First, clean the furniture to remove any dirt, mildew, or mould. You can do this by filling a bucket with hot water and adding an ammonia-based cleaner. Wash the entire surface of the furniture with a sponge and spray it with a hose to ensure a complete rinse. If the furniture is not too dirty, a simple all-purpose cleaner, such as dish soap, will suffice. If the furniture is especially dirty, sprinkle some baking soda directly onto a damp sponge and scrub the surface.
Once the furniture is clean and dry, lightly sand the surface with fine-grit sandpaper. Sanding the furniture will help to roughen the surface, allowing the paint and primer to adhere better. Be sure to test your sanding material in an inconspicuous spot to ensure it does not scratch the surface.
Next, apply a coat of primer designed for outdoor use and plastic surfaces. Primers will ensure better coverage of the new paint. Once the primer is dry, it is time to paint. Choose a high-quality outdoor spray paint that is specifically formulated for plastic and is durable and weather-resistant. A satin finish is recommended for plastic surfaces. Apply multiple thin coats, allowing each coat to dry in between, to prevent drips and ensure even coverage.
After painting, apply a sealant to protect the surface and extend the life of the paint job. To maintain your newly painted furniture, regularly clean it with a mild soap and water solution and avoid harsh chemicals or abrasive cleaners. You can also apply a protective coating, such as a UV-resistant spray, to prevent fading and discolouration.

Apply a sealant
To protect your plastic outdoor furniture from the elements and ensure its longevity, you should apply a sealant after refinishing. This will help to extend the life of the paint job and provide added durability.
Firstly, choose a sealant that is designed for outdoor use and will protect against the sun's UV rays. You can find these at your local home improvement store, usually in spray can form. Before applying the sealant, ensure that your furniture is clean and dry. Use a mild soap and water solution to remove any dirt and debris from the surface, and then allow the furniture to dry completely.
When you are ready to apply the sealant, shake the can well. Hold the can upright, around 12 inches (30 cm) from the surface of the furniture. Apply the sealant in a steady back-and-forth motion, ensuring you cover the entire surface evenly.
It is important to work in a well-ventilated area when applying the sealant, as the fumes can be harmful if inhaled. Consider wearing a respiratory mask to protect yourself.
Allow the sealant to dry completely before using the furniture. Refer to the product instructions for the recommended drying time, as this may vary depending on the brand and type of sealant used.
