Spraying Styrofoam

Did you know you can use some spray paints directly onto Styrofoam?

Many spray paints will eat into Styrofoam soon after painting. This is due to the kind of solvents in the paint.

Sugar Artists’ Acrylic and uses an alcohol based solvent made from sugar cane. It does not attack the foam.

MTN Water Based also contains alcohol as a drying agent, and does not contain solvents that eat foam.

After testing we can recommend that you can safely use MTN Water Based and Sugar Artists’ Acrylic paints directly onto foam with no primer.

Most of the other paints we carry, including our main ranges Ironlak, MTN Hardcore and MTN 94 will all attack the foam, unless an appropriate primer is used. MTN 94 Foam Primer is available which is used as a undercoat to protect the foam, in which case any paint can then be used on top of the primer.
