What You'll Learn
Krylon spray paint can be used on plastic and metal surfaces
Krylon offers a range of spray paint products specifically designed for use on plastic and metal surfaces. For plastic surfaces, Krylon recommends using their Fusion All-In-One spray paint, which provides 5X stronger adhesion and a long-lasting finish without the need for a primer. For metal surfaces, Krylon suggests using their Fusion All-In-One, COLORmaxx, or Rust Tough with Anti-Rust Technology products, which provide stronger protection against rust.
When applying Krylon spray paint, it is important to follow the instructions on the can. Hold the can the recommended distance away from the surface and apply several light coats, waiting 30-60 seconds between each coat. Start and finish each spray pattern off the object and release the spray tip at the end of each pass to ensure even coverage. Use a smooth, even sweeping motion and overlap each spray pattern by about one-third.
It is worth noting that some users have reported issues when using Krylon spray paint on polystyrene surfaces, stating that the paint melted the polystyrene or caused it to wrinkle and vein. However, others have found success by using a primer specifically formulated for polystyrene or model car kits, such as a lacquer primer, before applying the Krylon paint.

Spray paint melts polystyrene foam
Spray paint can melt polystyrene foam, but not all spray paints will do so. The melting occurs when the spray paint affects the physical properties of the polystyrene. The styrene strands in polystyrene react with the acetone in spray paint, causing the foam to dissolve.
Krylon spray paint is available in a variety of formulations, some of which can be used on plastic. For example, Krylon Fusion All-In-One is a no-prep, one-step paint that can be used on plastic and vinyl. However, Krylon spray paints that are not specifically designed for use on plastic may melt or craze the material, giving it a wrinkled appearance.
To prevent spray paint from melting polystyrene foam, a foam-safe sealer can be applied before painting. Two coats of polycrylic, a water-based protective finish, can be used to seal the foam and create a suitable surface for painting. If a foam-safe sealer is not available, spray paints with limited solvents or chemicals are less likely to harm polystyrene foam. Applying very thin coats of solvent-based spray paint may also prevent melting, as the paint will not penetrate deeply into the foam.
It is important to note that some spray paints are more likely to cause melting issues than others. Oil-based, latex, or enamel-based spray paints, for example, can cause melting issues. Enamel-based paints are particularly hazardous to polystyrene foam as they contain chemicals such as dimethyl ketone, propanone (acetone), and methyl ethyl ketone. Therefore, it is crucial to check the ingredients of a spray paint before using it on polystyrene foam to ensure it will not cause damage.

A primer can protect polystyrene from spray paint
Krylon spray paint can be used on plastic surfaces, including polystyrene. However, spray paint can sometimes melt polystyrene, so it is recommended to use a primer first to protect the polystyrene from the paint. A primer will create a barrier between the polystyrene and the paint, preventing the paint from melting the plastic.
There are several primers on the market that are specifically designed for use on polystyrene. These primers are highly adhesive and create a smooth surface on the polystyrene for the paint to adhere to. Examples include the Montana POLYSTYRENE PRIMER, the AeroPrime Polystyrene Primer, and the DUPLI-COLOR STYRO PRIMER.
When using a primer on polystyrene, it is important to follow the manufacturer's instructions. In general, it is recommended to apply at least three thin cross-coats of primer to the polystyrene surface, making sure that there are no gaps or pin holes in the coating. The temperature and humidity should also be within a certain range for optimal results.
By using a primer, you can help protect the polystyrene from the potentially damaging effects of spray paint and ensure a more durable and aesthetic finish. It is always a good idea to test the primer and paint combination on a small, non-visible area of the polystyrene first to ensure compatibility and avoid any unwanted reactions.

While Krylon Fusion All-In-One is a versatile and effective paint and primer, it is always a good idea to test it on a small area first, especially when working with polystyrene. Some users have reported that spray paint, including Krylon, can melt polystyrene or cause crazing, giving it a wrinkled or veiny appearance. However, using a primer specifically formulated for polystyrene or model kits can help create a barrier that protects the plastic.

Krylon spray paint can be used on glass
Krylon spray paint can also be used on plastic, vinyl, and other surfaces. However, when using Krylon spray paint on polystyrene, it is important to note that the paint may react with the plastic and cause melting or a wrinkled appearance. This is due to the chemical composition of the paint and the polystyrene reacting with each other. To prevent this, a primer or buffer should be applied first. A good primer that is not made from the same oil/chemical makeup as the paint can act as a barrier to protect the polystyrene.
Krylon Fusion All-In-One is a paint-and-primer product that can be used on a variety of surfaces, including glass and plastic, without the need for extensive preparation. It provides a durable finish and strong adhesion, protecting surfaces from rust, UV fading, and weather damage.
When using Krylon spray paint, it is important to follow the instructions and recommendations provided by the manufacturer to ensure the best results and to avoid any potential issues. It is also worth noting that Krylon spray paint cans and plastic caps are recyclable, so be sure to check your community guidelines for proper disposal and recycling practices.
