Best Paint for Styrofoam – Buyer’s Guide
How to Paint Styrofoam
Being a remarkably porous material, styrofoam is not as straightforward and easy to paint as other materials. By following these steps, however, you will be able to fully and expertly paint any object made of this plastic.
1. Select the Paint
Before doing anything, you need to select the right kind of paint for your task. Luckily, this guide already provided you with reviews for three of the best paint for styrofoam options on the market. Additionally, you will have to select the right colors for your objectives.
2. Prepare the Paint
After you have selected the right paint, you will have to prepare it. The way to do this depends largely on the type of paint and its presentation. If you are dealing with acrylic paint, you will have to pour a small amount of each paint you will be using in a container. If you want to mix colors to get a particular tone, you will have to do that.
3. Apply the Paint
Finally, the time has come to begin painting your styrofoam object.
First, dip your brush into the paint lightly. Then, apply it to the object carefully. If you are using spray paint, set the object down on a carpet of old newspapers and spray it. Move it a few times to get all the spots covered.
4. Spread and Even Out the Paint
Most likely, after applying your first coat of paint, the layering will be uneven and rough. To fix this, use a brush to spread and even out of the paint. Because it’s such a porous material, styrofoam will often require various strokes to retain the paint.
If regular strokes from side to side do not work, you may have to dab the paint into cracks and white spots in the styrofoam. Before moving onto the next step, make sure that all the surface is completely covered in an even way.
5. Let the Paint Dry
At this point, there is nothing left to do but let the paint dry. Depending on the type of paint, this will take between 10 and 20 minutes. However, to be completely sure, you can check out the manufacturer’s instructions for your paint of choice. To prevent damages to it or the styrofoam, try to let the paint dry naturally instead of using a blow dryer or anything else.
6. Apply Additional Coats of Paint
Once the paint has dried, you will likely have to apply additional coats of paint to get a truly professional, perfect result. To do this, repeat the previous two steps, first applying a coat of paint that covers the entire object and then letting it dry. Once the paint has dried and there are no light or white spots, the styrofoam painting job is ready.
