How to Color Foam Rubber

Whether you are coloring foam rubber to use for decoration or just want to change the color of a toy, you'll need to use the right materials to get the proper look and not accidentally melt your foam rubber model in the process.

Painting foam rubber takes a little more time than painting other types media, but you will love the results that you get from spending the extra bit of time.

  1. Spackle over any dents or gashes in the foam rubber. If you are painting a piece of that has been damaged, then you will need to fill it in thoroughly before you paint. You can use the paintbrush to spackle in the holes; it will need to dry for at least 24 hours.

  2. Sand the spackle surface smooth, using the sandpaper to flatten any rough edges. This will make the spackle and the foam rubber more receptive to the paint. Use only light pressure so that you do not wear away any of the foam.

  3. Spray paint the foam rubber piece, holding it at least six inches away so that the paint's vapors do not wear away the foam rubber. Because of this spraying distance, you may need to apply multiple coats. You should wait about five minutes in between each coat.

  4. Tip

    If you are grinding up foam rubber, then you can mix in water-based paint.


    Using acetone-free spray paints will prevent the foam rubber from disintegrating.
