Item details

12"x 12"x 4" Polystyrene Block

Expanded Polystyrene (EPS) foam or Styrofoam™ is great for making light weight crafts and more. Unlike packing foam, our EPS foam has a density of 1 lb density and can be cut/ sanded to get the shape you want. We work with EPS foam on a regular basis and create sculptures, signage, & architectural installments like crown molding, props, and more. If you have a specific size that you would like cut, let us know the length x height x width and we will be happy give you a quote.

Here are a few Tricks of the Trade:

Tools great for shaping polystyrene foam

80 Grit Sandpaper
Wire Brush
Serrated Knife
Hot Wire
Heat Gun (gives the surface a cool rock texture)
Hot Knife
A few products that work great for coating polystyrene and can be found in most building supply stores are:
Plaster of Paris
Latex Rubber
Drywall Mud
Polyurethane Coating (we will be offering this product soon)
Paper Mache
Elmer's Glue
Mod Podge

If you want a more "rock" like surface, a 50/50 (give or take) blend of a latex primer and plaster joint compound rolled on will get a real hard coating. Refrain from using aerosol or anything that contains high levels of VOC directly on polystyrene. Chemicals can break down/ dissolve polystyrene. Kilz® Max Water-Based Primer contains low VOC and makes a great primer when prepping your polystyrene surface for a coating. It will help strengthen the surface and will allow your hardcoating to adhere better.

We strive to make sure you are 100% satisfied. If for any reason you are unhappy with a transaction or have any questions, please don't hesitate to let us know. We look forward to servicing you!!
