EPS Hard Coating and Polystyrene Hard Coating are the same product that create a ultra hard coating, imstant set plastic shell. Some even call Polystrene "Whie Bead Board". The Polystyrene is cut using a Hot Knife either by hand or CNC hot knife machines and cut anything in a shape limited only to your imagination. Being a soft product however is where the SprayEZ EPS or Polystyrene Hard Coating comes to play creating a instant set plastic ultra hard shell.

EPS Hard Coating – A new generation of a plural component, instant set plastic skin for application over polystyrene. Theme Parks often use polyurea as a protective coatinging over foam, EPS and other structures to create ornamental building fascia, themed characters, artificial rocks, pools and environments., Haunted Houses, Sign Makers or where ever an ultra tough waterproof skin is needed.

To date EPS Hard Coating is the only plastic skin hard coat to offer both an E-84 Class 1 rating and act as a microcellular polymer. Instead of slight shrinkage as in the case of most hard coats EPS Hard Coating actually goes through a mini expansion process which helps to reduce to eliminate pinholes in even the lower density Polystyrenes, this also offers you higher dry mills for your money.

Due to the very high physical properties of EPS Hard Coaingt it cures to a very sand able, workable skin.
