Perhaps you created a new craft project using Styrofoam, but it feels incomplete. A dash of color should give some life to your project. But then the question arises, what is the best paint for Styrofoam. In this article, I will answer that very question as well as some others that may come up.
The best paint to use on Styrofoam is acrylic paint. Latex paint is a close second. For painting on Styrofoam, the best paint that I would recommend is Vallejo Medieval Colors Paint Set. It has a variety of lightfast and opaque colors. The consistency of this paint allows for very uniform coats.
But this is only a basic idea of what paint is best. In this article, I will go over each type of paint as well as other paints that you can use for your project. So, I recommend reading the entire article.
What Is The Best Type Of Paint For Styrofoam?
When it comes to painting on Styrofoam, the main issue that arises is its porous structure. As a result, you will need several coats of paint to get the result you are looking for. And spray paints may eat away at it. For this reason, water-based acrylic paint is the best type of paint for Styrofoam, but there are still other options for painting your Styrofoam crafts.
These are latex, tempera, and some specific types of spray paint. Let us look at the advantages of using each of these paints.
Acrylic is a fast-drying paint. It is mainly water-based but becomes water-resistant when dry. As a result, it is ideal for painting on Styrofoam. It is a very porous material for painting. Acrylic paint adheres best to the surface of Styrofoam, and when compared to the other paints on this list, it also lasts the longest.
Latex paint is another type of water-based paint. This type of paint, like acrylic paint, is made up of acrylic resin. This type of paint is more suited to painting larger areas. But it does not last as long as acrylic paint does.
Latex paint is a slow-drying paint, and it covers more surface area. As a result, you will require fewer coats of paint while painting your project. But latex paint is not as flexible as acrylic, which is why it may flake and crack more in fluctuating temperatures when compared with acrylic paint.
Based on whether your project will have to face varying temperatures, such as being kept outside, you can pick latex paint over acrylic due to its saving more time and paint.
Tempera is a fast-drying, permanent paint made up of colored pigments mixed with a water-soluble binder medium. Its paintings are very long-lasting examples of this, existing from the first century AD.
This is water-based paint that adheres well to the surface of the foam. This is a very readily available type of paint, so you can find it in almost every art and crafts store. Projects that may be exposed to water should not use this paint. Another downside to this is the limited color option and that it does not mix well with other paints.
Spray paint is paint that comes in a pressurized container and is released in spray form. It leaves a smooth finish and even coats the painting surface. Most spray paints should not be used to paint Styrofoam as it can eat away at it. But model spray paints can be used for painting Styrofoam as they are specifically designed to be used for it.
Should You Mix Acrylic And Latex Paint To Paint On Styrofoam?
Considering that acrylic and latex paints are the two best options when painting on Styrofoam, you might want to mix them both. You can mix these two colors rather safely without worrying about ruining them since they are both water-based. You mix them to get the perfect texture and or color for your project.
As I mentioned earlier, both these paints are very similar, being water-based. The main difference is their lifespan. Acrylic is more suited to crafts due to this.

How to Paint on Styrofoam?
Now that we have a clear idea about what kind of paint to use and which are some of the best paints you can buy, let us get ready to paint on Styrofoam. Before anything you need to first prepare everything you need. This includes:
- The paint you chose
- A paintbrush
- Plastic plates, cups, or paper
- Newspaper or tarps
- Fine-grit sandpaper
Sealing the Styrofoam
Before applying any paint to your Styrofoam applying a sealant can help in the painting process. Using a sealant can fill in any cracks in the Styrofoam and provide you with a solid base to paint on.
The process of sealing the Styrofoam is easy. A regular craft sealant will work. Just apply it on the surface using a foam brush and wait for it to dry so you can paint. But I recommend following the instructions for the specific sealant you are using.
Priming The Styrofoam
Many artists may choose not to use a primer before painting on Styrofoam, but most professionals would see it as a must. Using a primer before applying any paint to the Styrofoam would ensure a much more rich and professional quality finish. Priming a surface before painting allows for the truest color to come through. Making it an excellent base.
When applying primer make sure to apply only a thin layer of it onto the Styrofoam and once it dries you can sand it to fill in any remaining gaps from the sealant and apply a second layer if need be.
Painting The Styrofoam
Now that you have prepared the Styrofoam, you can start painting. Prepare the kind of paint that you have chosen to use. If you’ve chosen acrylic paint, take one of the plastic plates or cups and pour out the amount of paint that you plan to use on the Styrofoam. You can even mix and match the colors to your liking. Depending on the type of paint, it will have its own methods.
After that, dip your brush into the paint and start applying it to the object slowly and carefully. In the case of spray paint, set the object down on the newspaper or tarp and begin spraying it. Move it around a bit to make sure you have sprayed all the spots enough.
After applying your first coat of paint, you will notice that the layering may be a little uneven and rough. You can use your brush to even out and spread the paint more and try to fix this. Due to the surface of Styrofoam being so porous, you may require multiple strokes to get the desired outcome.
Cover all the surfaces completely and evenly before letting them dry. This ensures a better result. I would recommend letting the paint dry naturally instead of using a dryer to prevent any damage to it.
Once the paint dries, you will most likely need to apply a second coat following the same process, and once it dries without any white or light spots, you are done with the painting process.
How To Paint Different Types Of Styrofoam
Now that you have a basic idea about how to better paint on Styrofoam let us look at the different types of Styrofoam crafts. And the different ways to paint on these Styrofoam crafts.
Painting Styrofoam Balls
You can use Styrofoam balls for varied types of art projects. Making people’s heads, planets, snowmen, and round surfaces may seem challenging when it comes to painting, but there are some easy tricks to it.
Instead of directly using the sealant on it, brush the area with a little glue, then cover it with a piece of fabric. After that, continue the priming and painting process. You can also rub the ball with another Styrofoam ball, like sanding, for a less drastic and lighter result.
When it comes to painting it after priming, there is no easy way to use a roller or a brush. In this situation, spray painting is your best option. In that case, center it on a wooden skewer and hold it at least eight inches from the can before you start spraying it. Make sure to turn the skewer so you get paint onto all the surfaces.
After that, place the skewer on a sturdy surface and leave it to dry, then apply a second coat if needed. I would recommend repeating the process till you are satisfied with the results.
Painting Styrofoam Ceiling Tiles
Another type of Styrofoam project used often is Styrofoam tiles. Painting the tiles after installation often leads to less paint being used. You will tire yourself much faster by painting above your head. Whereas painting it before installation means saving extra paint for the metal strips that will hold it up.
Before you can even prime the Styrofoam, you will need to mark off the edges with painter’s tape. This is to prevent any excess paint or primer from getting onto any of the walls or other surfaces you do not want. After that, you can apply the primer.
For the sake of ceiling tiles, you should use chemical-free and water-based primers as chemical primers will damage the tiles. Once you have the right primer, use a roller brush to cover the large areas. After that, use the hand brush for the more detailed and smaller areas. As before, do this until it is completely covered.
Once the primer is dry, you can begin painting, just as before, being sure to use water-based acrylic paint and apply the paint in the same manner as you did the primer. Then, after it dries, look for any white spots and apply a second layer till you are satisfied with the result. And with that, you are done painting your Styrofoam tiles.
