Carved Granite From Foam

Acetone will eat away at your styrofoam, and while that’s not exactly what I would call a newsflash here, but Creativeman uses it to great advantage in his instructable on how to use this to create really good looking granite lettering.  This is a great way to create a sandblasted stone sign for use on cemetery columns, or to add depth to your tombstone, and it requires only the most rudimentary of skills.

The process is simple.  Cut your pre-printed letters out with an exacto knife, glue them to your styrofoam, and then spray paint the styrofoam.  It’s literally easier than breathing, but it adds a great level of detail to your lettering or sign.


Items needed to complete this include:

  • Styrofoam
  • Printout of your letters (each letter cut)
  • Elmer’s glue
  • Spray paint containing acetone
