Spray paint is a versatile and inexpensive way to breathe new life into plastic items, from furniture to accessories. However, the wrong type of paint may blister, bubble, or flake, so it's important to choose a paint specifically formulated for plastic, such as Krylon, Valspar, or Rustoleum. To achieve a glossy finish on plastic, the right preparation and technique are key. Firstly, ensure your work area is well-ventilated and protected from overspray, which can cause paint dust that will dull the final sheen. Next, clean the plastic surface and use sandpaper to create a textured base for the paint to adhere to. Apply a suitable primer, then, once dry, spray the plastic with your chosen paint colour, sweeping the can back and forth to achieve an even coat. Finally, for a professional finish, add a layer of clear gloss finishing spray to boost shine and protect against scratches.

What You'll Learn
Choose the right paint
Choosing the right paint is crucial when it comes to spray painting plastic. The wrong type of paint may blister, bubble, flake, or simply fail to adhere properly to the plastic surface. Therefore, it is important to select a paint that is specifically formulated for plastic surfaces or that is suitable for use on plastics.
Several companies offer spray paints suitable for plastic, including Krylon, Valspar, and Rustoleum. For example, Krylon offers a range of finishes, from textured to metallic. If you are using spray paint specifically designed for plastic, you may not need to prime the surface beforehand. However, if you opt for regular spray paint, it is recommended to use a primer to ensure the paint adheres properly and does not peel.
When choosing a primer, opt for a plastic primer specifically designed for use on plastic surfaces, such as Rust-Oleum Specialty Plastic Primer Spray. Follow the directions on the can for the best results. Before applying the primer, lightly sand the plastic surface with fine-grit sandpaper to create a texture that the primer can adhere to. This will help ensure a smooth and even finish.
In addition to choosing the right paint and primer, consider the finish you desire. If you want a glossy finish, look for high-gloss spray paint options. Enamel paints are a good choice for primer when aiming for a glossy finish, as they smooth uneven surfaces and prepare the material for glossy paint adhesion.

Prepare your work area
Before you start spray painting, it is important to set up your workspace. This will ensure that you have a smooth and efficient painting process. Firstly, decide on a location for your project. It is recommended to work outdoors or in a well-ventilated area. If you are working indoors, ensure that the space is adequately ventilated and protected from other areas, as spray paint tends to spread and overspray can produce a fine dust that will dull the sheen of your paint job. Consider working under a patio awning or in a garage with the door open. Additionally, make sure your workspace is separate from surfaces that you do not want to get paint on.
Once you have chosen your location, prepare the surface on which you will be working. It is important to work on an absorbent material that can catch any paint overspray. Cardboard or a drop cloth are good options. For added protection, you can create a single-use spray booth with a cardboard box or lay down some newspaper over your drop cloth. This will help catch any excess paint and make cleanup easier. If you are working outdoors, be mindful of the wind direction to avoid paint drifting onto unwanted surfaces.
Now, it's time to gather your materials. You will need your spray paint, which should be specifically formulated for plastic surfaces. Additionally, you may need a plastic primer if your paint is not designed for plastic. Other useful items include a damp rag or a sanitizing cleaner to wipe down the surface of your plastic item, ensuring it is free of dirt, grime, and mould. If your plastic item has existing paint or coatings, you may also need sandpaper to smooth the surface and create texture for the paint to adhere to. Don't forget to wear a painting mask to protect yourself from paint fumes.
Before you begin painting, take the necessary steps to protect yourself and your surroundings. Ensure that you are wearing appropriate protective gear, such as a painting mask and gloves. If you are working near flammable materials or substances, be extremely cautious and remove them from the vicinity. Spray paint cans can produce flammable vapours, so avoid any sources of heat or ignition during the painting process. It is also important to avoid eating or drinking in the work area to maintain a clean and safe environment.

Clean the plastic
To prepare plastic for spray painting, it is important to start with a clean surface. This will ensure that the paint adheres properly and that there is no unwanted debris on the plastic. Here is a step-by-step guide to cleaning plastic before spray painting:
Firstly, if the plastic item is small, fill a sink with warm water and add a teaspoon of liquid dish soap. Wash the item in the sink using a cloth. Alternatively, if the item is larger, fill a bucket with warm soapy water and use a sponge or cloth to clean the item. Ensure that you wipe down the plastic item thoroughly, removing all dirt and grime. If the item is used outdoors, it is recommended to use an all-purpose or sanitizing cleaner to wipe down the surface. This step is especially important if there is mould or mildew present.
Next, if the plastic is older, it may be necessary to remove any loose paint or other coatings previously applied. Use sandpaper to gently smooth the surface and give it a light texture that the primer and paint can adhere to. Rinse the surface with water and wipe it down with a tack cloth, ensuring that it is completely free of debris. Allow the plastic to dry completely before proceeding to the next step.
Additionally, if there are any hardware or attachments on the plastic item, it is advisable to remove them before cleaning. This will ensure that you can clean and paint the individual components more effectively.
By following these steps, you will have a clean and prepared plastic surface ready for spray painting. Remember to always work in a well-ventilated area and protect your surroundings with drop cloths or cardboard to catch any paint overspray.

Sand the plastic
Sanding the plastic surface is a crucial step in achieving a professional-looking paint job. Here's a detailed guide on how to sand plastic before spray painting:
Firstly, it's important to understand why sanding is necessary. Plastic is not a porous material, and unlike brick, stone, or wood, it doesn't easily absorb paint. By sanding the plastic, you create a rougher surface that the paint can adhere to, ensuring that your paint job lasts longer and doesn't chip or peel off.
When sanding, use fine-grit sandpaper or a fine-grit sanding block. Avoid using very coarse sandpaper, as it can damage the plastic. You're aiming to create a matte finish and a slightly textured surface, not to remove all the existing paint or coatings. If there is loose paint or coatings on older plastic items, gently sand the surface to smooth it out, then rinse thoroughly with water and let it dry completely.
For best results, sand the plastic lightly and evenly. The goal is to create a uniform texture across the entire surface. This will ensure that the paint adheres evenly and helps achieve a smooth and consistent finish.
After sanding, it's crucial to remove any plastic dust produced during the process. Use a damp cloth or rag to wipe down the surface. You can also use mineral spirits or isopropyl alcohol for this step, which will ensure that all the dust is removed. Make sure to work in a well-ventilated area when using these spirits, and be cautious as the rags can become flammable.
Once you've finished sanding and cleaning the surface, you can move on to the next step of priming the plastic. A good primer will help the paint adhere even better and create a more durable finish. Remember to always follow the manufacturer's instructions and work in a well-ventilated area when spray painting.

Apply the primer
To make spray paint shine on plastic, you will need to apply a primer. This is an important step to ensure the paint adheres properly to the plastic surface and does not peel, chip, or crack.
Start by selecting a primer that is specifically designed for plastic surfaces. Some popular options include Krylon Fusion for Plastic and Rust-Oleum Specialty Plastic Primer Spray. Check the label on the back of the can for specific instructions, as different primers may have varying application methods.
Before applying the primer, it is crucial to prepare the plastic surface. Use a fine-grit sanding block or 120-grit sandpaper to lightly sand the surface, giving it a dull finish. This process provides texture, creating a better surface for the primer to adhere to. After sanding, use a dry brush, such as a large paintbrush, to dust off any debris. Then, wipe the surface with a damp cloth to ensure it is clean and free of any remaining dust or dirt. Allow the object to dry completely before proceeding.
Once the surface is prepared, you are ready to apply the primer. Shake the can of primer as instructed, and hold it about 12 to 18 inches away from the object. Begin spraying the primer in light, thin coats, sweeping the can back and forth in a vertical or horizontal motion. Avoid pointing the nozzle directly at one spot, as this can result in an uneven application. Instead, keep the can in motion as you spray.
Let the primer dry completely according to the manufacturer's instructions. You may need to apply multiple thin coats, depending on the primer's instructions and the coverage required. Ensure you follow the directions on the can for the best results.
