What is Styrofoam?

Styrofoam is a brand name for a type of extruded polystyrene foam made by Dow Chemical Company. The blue bead foam most often associated with the Styrofoam name is used as building insulation and to make craft supplies like model airplane kits. You can find this type of foam in different densities, indicated by a number following the word “board.” The lower the number, the more dense and rigid the resulting product will be.

What is the best paint for Styrofoam?

There are a few different types of paint that can be used on Styrofoam, but the best one to use is acrylic paint. This type of paint is easy to find at most craft stores, and it will adhere to the surface of the Styrofoam without peeling or flaking off.

Styrofoam is a porous material, so it is important to prime the surface before painting. This will help the paint to adhere better and prevent it from soaking into the Styrofoam. Once the primer is dry, you can start painting your Styrofoam project with acrylic paint.

How to paint Styrofoam

Styrofoam can be painted, but it needs to be prepared first so the paint will stick and not flake off. You will need to sand the surface of the Styrofoam, then apply a primer and let it dry. Once the primer is dry, you can then apply your paint of choice.

Surface preparation

Styrofoam is a very versatile material that can be used for a variety of purposes, from crafts to construction. It is also very easy to work with, and can be cut, shaped, and painted to your liking.

Before you start painting Styrofoam, it is important to prepare the surface properly. Begin by sanding the foam with a fine-grit sandpaper to create a smooth surface. This will help the paint adhere better and create a more professional-looking finish.

Once the surface is sanded, wipe it down with a damp cloth to remove any dust or debris. Allow the foam to dry completely before beginning to paint.

When painting Styrofoam, it is best to use a latex-based paint as it will adhere better than other types of paint and will not chip or peel off easily. You can also use spray paint designed for use on plastic surfaces.

Apply the paint evenly over the surface of the foam, using light coats so that the paint does not drip or run. Allow each coat to dry completely before adding another. Once the final coat is dry, you can then proceed to cut, shape, or otherwise manipulate the foam as desired.

Applying paint

When you are painting Styrofoam, it is important to use a paint that is specifically designed for the material. You should also choose a paint that has a matte finish, as this will help to hide any imperfections in the surface of the foam.

To paint Styrofoam, start by priming the surface with a white primer. Once the primer is dry, apply a thin layer of paint to the foam using a brush or roller. For best results, use several thin coats of paint rather than one thick coat. Finish by sealing the paint with a clear sealant.

Drying and curing

It is important to allow the paint to dry thoroughly between coats. A hairdryer can be used to speed up the process. Once the final coat of paint is dry, the Styrofoam should be cured in an oven at 200 degrees Fahrenheit for 30 minutes. This will ensure that the paint is properly adhered to the surface and will not chip or peel off.

Tips for painting Styrofoam

Have you ever wanted to add some color to a Styrofoam project, but weren’t sure if paint would stick? Luckily, there are a few ways you can go about painting Styrofoam so that the color will adhere properly and your project will look great!

Before you start painting, it’s important to rough up the surface of the Styrofoam so that the paint will have something to grip onto. You can do this by lightly sanding the surface with fine-grit sandpaper or by using a spray primer specifically designed for Styrofoam. Once the surface is roughed up, you’re ready to start painting!

Acrylic paint is a good option for painting Styrofoam because it adheres well and dries quickly. You can also use spray paint, but be sure to use several light coats rather than one heavy coat so that the paint doesn’t end up dripping and ruining your project.

Once you’ve chosen your paint, apply it to the Styrofoam in thin, even layers. Allow each layer of paint to dry completely before adding another. Once you’re finished painting, your Styrofoam project will be bright, colorful, and ready to display!


If your paint is not sticking to the Styrofoam, there are a few things you can do to troubleshoot the issue. First, make sure that you are using an acrylic paint. This type of paint will adhere best to the Styrofoam. Second, lightly sand the surface of the Styrofoam before you begin painting. This will help create a rough surface for the paint to adhere to. Finally, try using a primer before you start painting. This will help the paint to better adhere to the surface of the Styrofoam.
