Acrylic paint is popular because it is so versatile and is a safe option when compared to other paints. But will acrylic paint stick to plastic? This type of paint is not made to stick to plastic and works best on a more porous surface like wood or paper. When applied to plastic, it will not have the staying power, especially if the item is handled often. However, by using compatible base coats, primers, and sealants, you can use acrylic paint for plastic.

Will Acrylic Paint Stick to Plastic?

Plastic is a non-porous and smooth surface, which is why painting plastic with acrylic paint is difficult. There is nothing the paint can grab onto, so you need to prepare the surface for painting. If you do not do any preparation and just start painting, the paint will peel and chip. Another reason paint does not stick to surfaces is if it is contaminated or dirty. So, the first step would be to clean the surface. You can purchase degreaser and cleaners, or simply wash the plastic surface with some warm soapy water and let it dry. There are quite a lot of different plastics out there and acrylic paint might work better on some and not at all on others. For example, the craft acrylic paints will need a primer plastic surface to stick to any plastic. Some other plastics that acrylic paint will not stick to at all include polypropylene, which has the recycling logo of number 5 inside a triangle displayed on the plastic item. Also, polyethylene with the numbers two and four do not provide a good surface for acrylic paints. Acrylic paint will also not adhere to Teflon, nylon, and silicon. In order for the acrylic paint to stick, you will need to prepare the surface by lightly sanding the plastic surfaces, applying a base coat or primer. The base coat must be a paint that is specifically made for plastic surfaces, then you can apply the acrylic paint over that. If using primer, it should also be designed for working on plastics. To provide even more durability, applying a clear sealant will do the job. A sealer might not be necessary; however, it does provide more permanent results. This is especially needed when it comes to painting outdoor plastic items. For convenience and easy use, you can get spray sealers.

Guide to Painting Plastic with Acrylic Paint

The plastic item you have at home, maybe it is a piece of furniture piece or miniature model, and you want to use acrylic paint for plastic. You can easily change how the item looks, even make it appear metallic. However, plastic does require preparation, otherwise, the whole paint job will be for nothing.

Preparing the Plastic Surface

To improve the final finish, it is a good idea to clean and if needed degrease the plastic surface. In most cases, some soap and water should do the job. Allow the item to dry and then you can lightly sand the surface to get rid of any coatings and make it more receptive to the primer. 180 to 220-grit sandpaper can be used for this purpose. Using a damp cloth, wipe any dust away. You can then use some rubbing alcohol to wipe the surface and let the item dry properly.

Applying a Primer

There are spray paints available that are specifically designed for plastics and do not need a primer. However, there might not be a color you want. So, you might want to consider regular acrylic paint for plastic. You will then need to apply one or two coats of primer for plastic. When spraying, make sure to cover or tape areas you do not want to be covered and preferably spray outside where there is plenty of air circulation. Otherwise, when spraying indoors, you must work in a well-ventilated area. You should also use some gloves, protective eyewear, and a mask for protection. Hold the sprayer or can about 12 to 18-inches away and spray in even, parallel movements that overlap. Cover the entire surface and then let it dry for several hours or follow the instructions on the primer container. The primer will provide an effective foundation for the paint. Spraying primer does provide a more even application, however, you can also brush primer on. When using the brush-on primers, you need a little patience as you do not want to leave any brush marks or bubbles. Apply thin coats of primer with a synthetic brush and let each layer dry thoroughly before applying another. Two to three coats might be necessary.

Acrylic Painting on Plastic

When using acrylic painting on plastic, you can follow a similar process when preparing the work environment. The work space should be well-ventilated and use a mask and protective eyewear when spraying. Also, cover and tape off any areas you do not want paint on. Some paints need to be prepared before use, always check the paint product for directions. You will need to shake spray cans before using them so they will apply smoother and more evenly. Hold the spray container perpendicular to the surface and apply more than one thin coat, rather than one thick coat. You might also want to thin acrylic paint to make it creamier in consistency if applying with a brush. This will help to lessen any brush marks and produces a smoother finish. You will need to apply two to three coats of paint and wait for each coat to dry before applying the next layer. Most paints dry in around 15 to 20 minutes and once the final coat has been applied, leave for 24 hours to dry properly. You can peel any tape away once you are finished painting before it dries. You can then also add some details onto the painted surface using stencils or adding your own designs.
