What You'll Learn
Fabric paint is not ideal for plastic
If you're considering using fabric paint on plastic, it's important to know that it's not the ideal option. There are several reasons why fabric paint may not produce the desired results on plastic surfaces. Firstly, fabric paint is not specifically formulated for plastic in the same way that multi-surface or plastic-specific paint is. This means it may not adhere to plastic as effectively, and you may encounter issues with the paint peeling or chipping off over time.
Another consideration is the drying time of fabric paint. Fabric paint tends to take a long time to dry completely, regardless of the surface it is applied to. This can make the painting process more cumbersome and time-consuming, especially when multiple coats are often required for adequate coverage. The lengthy drying time also means that it can be challenging to work on projects that require multiple steps or layers of paint.
Additionally, fabric paint may not provide the same level of durability as paints specifically designed for plastic. Plastic items, especially those used outdoors or exposed to weather conditions, require paint that can withstand the elements without peeling, fading, or chipping. Fabric paint may not offer the necessary protection, and the paint may deteriorate over time, compromising the aesthetics and functionality of the item.
While it is possible to use fabric paint on plastic, it is generally not recommended due to the potential challenges and limitations. Instead, opting for paints specifically formulated for plastic surfaces will yield better results and ensure the longevity of your project. These paints are designed to address the unique characteristics of plastic and provide a more durable and aesthetically pleasing finish.

Use acrylic paint instead
If you're looking to paint plastic, fabric paint is not the best option. It can be difficult to get fabric paint to stick to plastic, and it takes a long time to dry. You will likely need to apply several coats, which will extend the project time.
Acrylic paint is a better choice for painting plastic. It sticks well to rigid plastic, and you can use a spray primer first if you're worried about the paint chipping or peeling. You can seal the paint with varnish to protect it, especially if the item will be placed outdoors and exposed to the elements.
Before painting, it's important to prepare the plastic surface. Clean the plastic with warm water and mild dish soap to remove any dirt or residue, then dry it thoroughly. Next, use fine-grit sandpaper (120 to 220 grit) to lightly buff the surface in a circular or straight line motion. This will add texture to the plastic, helping the paint adhere better. If you are using multiple colours, you can use masking tape to create borders and avoid colour overlap. After sanding, wipe the surface with a tack cloth to remove any dust.
There are different types of sealants available, depending on the finish you want to achieve. You can choose from matte, glossy, or regular finishes. Sealants can be applied with a brush or spray can, and it's important to ensure each layer is completely dry before adding another. Oil-based sealants are a good option for items that will be left outdoors, as they are insoluble in water and will protect the paint from fading or washing away.

Prepping the plastic surface is necessary
Painting on plastic can be challenging due to its smooth and temperature-responsive surface, which makes it prone to cracking and flaking over time. To ensure that your paint job looks professional and lasts longer, it is crucial to prep the plastic surface properly. Here are the steps you need to follow:
Firstly, wash your plastic item with warm water and a mild dish soap to remove any dirt, dust, mildew, or algae that may be present on the surface. If you are working with a smooth surface, use a soft cloth, microfiber cloth, or sponge. For textured surfaces, a scrubbing brush or a sponge with some texture, such as a cellulose sponge, is more suitable. Rinse the object thoroughly to remove all soap residue and then let it dry completely.
Next, you need to sand the plastic surface. Use fine-grit sandpaper or a fine-grit sanding block to lightly buff the surface in a circular motion, paying extra attention to any shiny parts. This step is important because it gives the plastic a texture that the paint can adhere to. Make sure to wipe down the surface with a tack cloth after sanding to remove any dust or residue.
Once the plastic surface is clean and sanded, it is time to prime it. Choose a primer specifically designed for use with plastic, such as Krylon Fusion or Rust-Oleum Painter's Touch 2X Ultra Cover. Shake the can vigorously and hold it about 12 inches away from the surface. Apply the primer in light, even coats, using long sweeping dusting strokes. Wait for the recommended time, usually about 25 minutes, before applying the next coat.
After priming, you may need to seal the plastic surface, especially if you are using fabric paint, as it is prone to peeling off plastic. You can use a varnish or a clear coat to seal the surface.
By following these steps, you will ensure that your plastic surface is properly prepped and ready for painting with fabric paint. A well-prepped surface will help the paint adhere better and create a lasting and professional-looking finish.

Seal your project when finished
Sealing your project is crucial to ensuring your design's longevity. Fabric paint can be used on plastic, but it is not the ideal option. The paint is prone to peeling off plastic, so you must properly seal your project when you are finished.
Before you seal your project, it is necessary to prepare and prime your plastic to get good results. Wash your plastic item using warm water and mild dish soap to remove any dirt or residue that could ruin your project. If you are working with a smooth surface, use a soft cloth or sponge. For textured surfaces, use a scrubbing brush. Rinse the object, ensuring you remove all soap, and then dry it. Next, use sandpaper to lightly buff the surface in a circular motion to avoid scratches. Sanding the surface will give the plastic a texture that the paint will stick to. You can then wipe the surface down with a tack cloth and then with rubbing alcohol.
After you have primed your plastic, you can begin painting. Fabric paint takes a long time to dry, and you will likely need to use more than one coat. Once your paint is dry, you can begin sealing. There are several sealants available on the market, so you will need to choose the one that works best for your project. If your painted item will be left outdoors, you should use an oil-based elastomer sealant to prevent the colour from fading or washing away. If you want a clear finish, you should use a sealant made of polyacrylate resin.
If you are sealing fabric paint on fabric, you can seal your project by heat-setting the paint using an iron or clothes dryer, or applying a fabric medium before painting. For added durability, you can use a clear fabric sealant after the paint has dried.

Use multi-surface paint if plastic-specific paint is unavailable
While fabric paint can be used on plastic, it is not the ideal option. Fabric paint takes a long time to dry, is inconvenient to use, and is prone to peeling off plastic. If you cannot find paint that is specifically made for use on plastic, the next best option is to use multi-surface paint.
Multi-surface paint is the second-best option for painting on plastic. When purchasing paint for use on plastic, look for paint that is listed as being multi-surface paint. It is important to properly prepare and prime your plastic surface before painting to ensure that the paint adheres well and lasts long-term. This includes washing the plastic with mild dish soap and warm water, using a soft cloth or sponge for smooth surfaces or a scrubbing brush for textured surfaces, and then drying the surface. You can also use sandpaper to lightly buff the surface in a circular motion to give the plastic a texture that the paint can stick to.
After properly preparing the surface, you can apply the multi-surface paint. Once the paint is dry, it is important to seal it, especially if the painted object will be outdoors and exposed to weather conditions. You can use a clear sealer or varnish to protect the paint and prevent it from peeling or chipping.
Additionally, when working with paint and plastic, it is important to buy the proper supplies and follow the necessary preparation and sealing steps. Painting on plastic can be a great way to give new life to faded or boring items, but it is important to do it correctly to ensure a successful project.
