What You'll Learn
Use a primer
Painting plastic is challenging due to its chemical composition and smooth surface, which do not promote good paint adhesion. However, using a primer can help you achieve a flawless paint job on plastic surfaces.
Primers act as a base coat, creating a foundation for the paint to adhere to and allowing the true colour of your topcoat to shine through. To ensure paint adhesion on plastic, you should use a high-adhesion latex stain-blocking primer for interior plastics and a specialised primer formulated for adhesion to plastics for outdoor plastics.
Before priming, it is important to prepare the plastic surface. Clean the plastic surface with detergent and warm water, then let it dry. Next, scuff-sand the surface with 220-grit sandpaper to create a rough texture that will help the primer adhere. Finally, wipe off the sanding dust with a damp cloth and let the surface dry.
Once the surface is prepared, you can apply the primer. For interior plastics, use a high-adhesion latex stain-blocking primer. These primers are designed to provide a strong base for the paint to adhere to and can help cover any stains or imperfections on the plastic surface. For outdoor plastics, use a specialised primer formulated specifically for adhesion to plastics. These primers are designed to withstand the elements and provide a durable finish.
After priming, you can apply your chosen paint. It is recommended to use one coat of primer and two coats of paint to achieve a professional finish. Allow each coat to dry completely before applying the next one.

Choose the right paint
Painting plastic can be challenging due to its chemical composition and smooth surface, which do not promote good paint adhesion. Additionally, plastic's tendency to expand and contract can lead to flaking, even if the paint seems securely adhered. However, with the right preparation and products, you can achieve a durable finish on plastic surfaces.
When choosing paint for plastic drawers, it is essential to select a paint specifically designed for plastic adhesion. Look for paints that mention "bonds to plastic" or "sticks to plastic" on their packaging. Some recommended brands include Rust-Oleum and Krylon, which offer a range of colours and finishes. Their products are known to work well on different types of plastics.
Before painting, ensure your plastic drawers are thoroughly cleaned and dried. Scuff-sanding the surface with fine-grit sandpaper can help create a better adhesion for the paint. Wipe away any sanding dust with a damp cloth and let the surface dry completely.
It is also crucial to consider the environment in which the painted drawers will be placed. For indoor drawers, a top-quality acrylic spray paint or interior latex paint can be used. If using spray paint, apply multiple light coats, allowing each coat to dry completely before applying the next. For outdoor drawers, use a spray paint specifically designed for outdoor plastics.
Additionally, priming the plastic surface before painting can further enhance adhesion and durability. Apply a coat of primer specifically designed for plastic surfaces and let it dry before applying the paint. Following these steps will help ensure a successful painting project for your plastic drawers.

Prepare the surface
Preparing the surface of plastic drawers for painting involves several steps to ensure the paint adheres well and the finish is durable. Here is a guide to help you through the process:
Step 1: Clean the Plastic Drawers
Start by giving the plastic drawers a thorough cleaning. Use a scrub brush and, if necessary, some soapy water to remove any dirt, dust, or flaking paint. If the drawers have mildew or algae, you may need to put in some extra effort and use a 3:1 water-bleach solution, keeping the area wet for about 20 minutes before rinsing and cleaning with detergent and warm water. Ensure you rinse the drawers with cool, clean water to remove any soap residue.
Step 2: Dry the Surface
After cleaning, ensure the surface of the drawers is completely dry. Use a clean, dry cloth to wipe down the drawers and remove any remaining moisture.
Step 3: Sand the Surface
Plastic is known for its smooth surface, which can hinder paint adhesion. To counter this, use fine-grit sandpaper to roughen the surface lightly. This process will give the paint something to stick to and help the finish last longer. Make sure to sand the plastic evenly to achieve a matte finish. Remove any sanding dust with a damp cloth and let the drawers dry again.
Step 4: Apply an Anti-Static Agent (Optional)
Plastic can easily take on a static charge, which attracts dust. To prevent this, you can spray an anti-static agent onto the surface.
Step 5: Apply an Adhesion Promoter
To further enhance paint adhesion, apply an adhesion promoter to the sanded and cleaned surface. This step is crucial for plastic parts made from Thermoplastic Polyolefin, as these plastics are inherently difficult to paint. The adhesion promoter will allow the plastic and the paint to fuse together properly.
Step 6: Prime the Surface
Before painting, it is recommended to prime the surface, especially if the plastic has defects or imperfections. Choose a plastic-specific primer or a high-adhesion latex stain-blocking primer suitable for interior or exterior use, depending on where your drawers will be placed. Apply the primer in light, even coats, following the manufacturer's instructions.
By following these surface preparation steps, you will significantly improve the chances of your wall paint adhering to your plastic drawers and achieving a long-lasting, high-quality finish.

Apply multiple coats
Painting plastic drawers can be a great way to improve their appearance and make them look neat and organized. It is important to prepare the surface properly and use the correct products to ensure the paint adheres well and the finish is durable.
To apply multiple coats of paint to plastic drawers and achieve a durable finish, it is important to follow the correct process. First, ensure the drawers are clean and dry. If there is any mildew, scrub the area with a 3:1 water and bleach solution, keeping it wet for about 20 minutes before rinsing and drying. Then, thoroughly clean the drawers with detergent and warm water, and let them dry completely.
The next step is to sand the drawers. Use 200-grit sandpaper to scuff-sand the surfaces to be painted. This will help the paint adhere better. After sanding, wipe down the drawers with a damp cloth to remove the sanding dust, and let them dry.
Before painting, protect the area around your workspace by covering it with plastic tarps, especially if you are using spray paint. Use blue tape to tape off any areas you do not want to paint, such as the inside front edge of the drawers. Place a piece of cardboard inside each drawer to prevent paint from getting inside, and prop it up with shims or scrap wood so it doesn't stick to the plastic.
When you are ready to paint, shake the can for a full minute. Hold the can about 12-18 inches from the surface and spray in a back-and-forth motion, using wide sweeping strokes. Apply the paint in light coats, ensuring you get full coverage and avoiding drips. Let each coat dry completely before applying the next one. Repeat this process for each additional coat. For perfect spray paint results, test the spray on a piece of paper taped to a wall, and hold the can as perpendicular to the surface as possible.
By following these steps and allowing adequate drying time between coats, you can successfully apply multiple coats of paint to plastic drawers, resulting in a durable and attractive finish.
