Foam board is a lightweight material that is easy to work with and cut to size. It is often used for crafts, models, and school projects. You can paint foam board, but it requires a few extra steps to get a smooth, professional looking finish.

What is Foam Board?

Foam board is a stiff, lightweight material that’s easy to work with and perfect for a variety of craft projects. Unlike paper-based boards, foam board doesn’t warp or ripple, so it’s ideal for painting. But because it’s so smooth, you’ll need to use the right type of paint and primer to get good results.

The Different Types of Foam Board

There are three main types of foam board: polystyrene, polyurethane, and extruded polystyrene. Polystyrene foam board is the most common and least expensive. It’s made of expanded polystyrene beads and is available in 3/16-, 1/2-, 5/8-, and 1-inch thicknesses. The surface is very smooth, making it ideal for painting. Polyurethane foam board is more expensive than polystyrene but is also much stronger and more durable. It’s available in 3/8- and 1-inch thicknesses. Extruded polystyrene foam board is the strongest and most expensive type of foam board. It’s made of extruded polystyrene beads and is available in 1/2-inch thicknesses.

Which Type of Foam Board is Best for Painting?

Foam board is a great material for crafts, school projects, and even framing artwork. And, because it’s so lightweight and easy to cut, it’s also a popular choice for temporary signage and exhibits. Whether you’re creating a one-of-a-kind piece or need to produce a large volume of signs, foam board is an excellent solution.

But what if you want to paint your foam board project? Can you paint foam board?

Generally speaking, yes, you can paint foam board. But there are a few things to keep in mind before you start painting, such as the type of foam board and the type of paint. In this article, we’ll explore the best way to go about painting foam board so that your project turns out looking great.

There are two types of foam board: extruded polystyrene (XPS) and expanded polystyrene (EPS). XPS foam board is made of closed-cell beads of polystyrene that are fused together with heat and pressure; EPS is made of open-cell beads that are fused together with chemicals. EPS is less dense than XPS, so it’s often used for projects that require lighter materials.

For painting purposes, we recommend using XPS foam board because it’s less likely to absorb paint and retains its shape better than EPS when cut or sanded.

How to Prepare Foam Board for Painting

Whether you want to spruce up some old foam board insulation or create a sign for your business, painting foam board is a relatively easy task. However, it’s important to take the necessary steps to prepare the surface of the foam board before painting, as this will ensure that your paint adheres properly and doesn’t peel off later.

To prepare foam board for painting, start by sanding it with fine-grit sandpaper to create a smooth surface. Next, wipe the foam board down with a damp cloth to remove any dust from sanding. Then, apply an even layer of primer to the foam board and let it dry completely. Once the primer is dry, you can paint your foam board with any color of paint you like!

How to Paint Foam Board

It is possible to paint foam board, but there are a few things to keep in mind. Foam board is made of a lightweight material and is therefore susceptible to damage. It is also difficult to get paint to adhere evenly to the surface of foam board. For these reasons, it is best to use a primer before painting foam board. You can also use spray paint, which will help to achieve a more even coverage.

Tips for Painting Foam Board

Foam board is a lightweight, durable material that is often used for crafts and modeling. It is easy to cut and shape, and it can be painted to create a variety of effects.

If you want to paint foam board, there are a few things you need to keep in mind. First, you need to use the right type of paint. Acrylic paint works well on foam board, but other types of paint can also be used. Be sure to test the paint on a small area of the foam board before beginning your project.

Second, you need to prepare the surface of the foam board before painting. This will help the paint adhere better and will also prevent it from peeling off later. To prepare the surface, sand it lightly with fine-grit sandpaper. Then wipe away any dust with a damp cloth.

Once you have prepared the surface, you can begin painting. Use long strokes and work in one direction to avoid creating brushstrokes in the finished product. If you want a smooth finish, you can use a spray primer before painting. Allow the paint to dry completely between coats.


It is possible to paint foam board, but it is important to use the right type of paint and to prepare the surface properly. Foam board is a porous material, so it will absorb paint if not properly sealed. You can use either latex or oil-based paint on foam board, but latex paint is easier to work with and dries more quickly. Add a primer to your paint to help it adhere better to the foam board surface.
