Painting recycled plastic furniture is an easy way to update your outdoor space. It is important to prepare the surface of the furniture before painting. This includes cleaning the furniture with a suitable product, such as an ammonia-based cleaner, and drying it thoroughly. Depending on the condition of the furniture, you may also need to sand the surface lightly to help the paint adhere better. Once the surface is prepared, you can apply a primer designed for use on plastic, followed by a coat of paint. It is recommended to use a combination paint and primer designed for plastic surfaces, or to prime the surface first and then apply a coat of spray paint.

Clean the furniture
To paint recycled plastic furniture, you must first clean the furniture thoroughly. This is an important step to ensure that the paint adheres well to the surface and that your final product looks smooth and professional. Here is a step-by-step guide to cleaning your recycled plastic furniture before painting:
Prepare the Cleaning Solution:
Fill a bucket with hot water and add an ammonia-based cleaner or a mild detergent. Ammonia will help remove any mould or mildew on older furniture. You can also use a paint thinner or a product like WD-40 to wipe down the surface. If your furniture is not too dirty, a simple dish soap will do the trick.
Scrub the Furniture:
Use a sponge, soft brush, or a scrub brush to wash the entire surface of the furniture. Pay special attention to any areas with dirt, debris, or mould. For furniture with layers or weaves, like resin wicker, use a small brush to scrub in between the layers to ensure a thorough cleaning.
Rinse the Furniture:
Use a hose with a pressurised nozzle attachment to spray down the furniture. Spray from multiple angles to ensure that all surfaces are rinsed completely. If you don't have access to a hose, you can use a damp cloth to wipe down the furniture, making sure to remove any soap residue.
Dry the Furniture:
Use a cotton towel to dry off the furniture and then allow it to air dry completely. It is important that the furniture is entirely dry before you start painting. Exposing the furniture to sunlight will also help speed up the drying process.
Sand the Surface (Optional):
If your furniture has been painted before, it is a good idea to lightly sand the surface using fine-grit sandpaper or a sanding sponge. This will help create a smoother surface for the new paint to adhere to. After sanding, wipe down the surface with a tack cloth to remove any dust.
Once you've completed these steps, your recycled plastic furniture will be clean and ready for the next step in the painting process.

Sand the surface
Sanding the surface of your recycled plastic furniture is an important step in the painting process. It helps to create a rougher surface for the primer and paint to adhere to. While plastic can be tricky to sand, as it can sometimes chip or peel, it is still worth doing, especially if the piece has been painted before.
To sand the surface, you will need to use a fine-grit sandpaper or a sanding sponge. Gently brush the entire surface with light pressure, being careful not to create visible scratches. If you notice any scratches appearing, reduce the pressure or use a finer grit. Remember to test your sanding material on a small, inconspicuous spot first. Once you have finished sanding, wipe down the surface with a tack cloth to remove any dust.
If your furniture is made of very smooth plastic, you may want to lightly roughen the surface with fine sandpaper or a sanding pad. This will help the varnish or paint adhere better. However, if your furniture is already smooth and has never been painted before, you may be able to skip the sanding step altogether and move straight on to priming.
It is important to note that you should not try to deeply sand plastic furniture as you would with wooden furniture. The goal is simply to create a slightly rougher surface for the paint to stick to, not to remove any significant amount of material.

Choose a primer
Choosing a primer is an important step in painting recycled plastic furniture. A primer will ensure that your paint adheres well to the plastic surface and will result in a more durable finish.
When choosing a primer, look for a product that is specifically designed for use on plastic materials. These primers are typically available in spray form and can be found at your local home improvement store. For example, you can use a plastic primer spray paint such as Dulux 325g Duramax Plastic Primer Spray Paint. If you want to save time and use a product that combines both primer and paint, you can opt for a product like Rust-Oleum 340g 2X Ultra Cover Paint+Prime Satin Blossom White Spray Paint.
It is also important to consider the type of primer that will work best with your chosen paint. If you are using an oil-based paint, an oil-based primer such as Cover Stain or Kilz is a good option. On the other hand, if you prefer a water-based paint, you can choose a water-based primer like Rustoleum's Professional Water-Based Primer, which is affordable and effective on plastic surfaces.
Additionally, you may want to consider the colour of your paint when choosing a primer. If you plan to paint your recycled plastic furniture in a colour that is not typically available for plastic materials, using a primer will be necessary. In this case, you can select a primer designed for outdoor plastic materials, which will provide a good base for your chosen paint colour.
Before applying the primer, ensure that the plastic surface is clean, dry, and smooth. This will help the primer adhere properly and create a better finish. Once the primer is applied, allow it to dry completely before moving on to the painting step.

Select the right paint
Selecting the right paint is crucial for achieving a smooth and durable finish on your recycled plastic furniture. Here are some factors to consider when choosing the paint:
Type of Paint
Spray paint is the best option for painting plastic furniture. It is easy to use, less time-consuming, and guarantees a smooth finish. Look for spray paint that is specifically designed to coat plastic surfaces. If you plan to use the same colour for multiple small projects, you can opt for a "multi-surface" spray paint. You can also use a combination of paint and primer designed for plastic surfaces, which will save you time and effort.
Primer
Priming is not necessary for all plastic furniture, but it can improve paint adhesion and the final look. If you wish to use a particular colour that is not available for plastic materials, priming is recommended. Choose a primer suitable for plastic materials, preferably an oil-based primer or a water-based primer like Rustoleum's Professional Primer. Apply the primer evenly across the surface and let it dry completely before painting.
Paint Colour and Finish
The colour and finish of the paint depend on your personal preference and the look you want to achieve. Bright and bold colours or pastel shades can give your recycled plastic furniture a vibrant look. If you prefer a more subtle and elegant style, consider grey tones or concrete shades. For a textured finish, Rust-oleum's Hammered Textured series can effectively hide flaws and imperfections.
Environmental Factors
If your recycled plastic furniture will be used outdoors, consider using environmentally friendly outdoor paints designed for weather resistance. Silk matt and glossy finishes are more hard-wearing and provide better protection against the elements. On the other hand, if the furniture will be used indoors, invest in higher-quality paint to ensure a durable finish.
Surface Preparation
Before painting, ensure the plastic surface is clean, dry, and smooth. Use a combination of dish soap, paint thinner, or ammonia-based cleaner to remove any dirt, grease, or mould. Lightly sand the surface with fine-grit sandpaper to create a slightly rough texture, which will help the paint adhere better. Remember to test your sanding technique in an inconspicuous spot to avoid visible scratches.

Allow time to dry
Allowing paint to dry is an important step in the painting process. It ensures that the paint adheres properly to the surface and helps to prevent any smudging or smearing. The amount of drying time needed will vary depending on the type of paint used and the number of coats applied.
When painting recycled plastic furniture, it is essential to follow the manufacturer's instructions for drying times. These instructions will provide specific guidance on how long to wait between coats and before using the furniture. It's worth noting that some paints may require longer drying times, especially if you're working in a humid environment or if the temperature is cooler.
To ensure the best results, it is recommended to allow each coat of paint to dry completely before applying the next one. This may involve waiting several hours or even days, depending on the paint type and environmental conditions. It's better to err on the side of caution and give the paint ample time to dry rather than rushing the process.
While waiting for the paint to dry, it's important to protect the furniture from any potential sources of moisture. Keep the furniture in a dry location, away from direct contact with water or high humidity. Additionally, avoid touching or handling the furniture during the drying process to prevent any accidental smudging.
Once the final coat of paint has been applied, it's crucial to allow sufficient curing time. Curing allows the paint to reach its maximum hardness and durability. This process typically takes longer than the initial drying time and can vary depending on the paint type and environmental conditions.
