Polymer Malta obtained by mixing sands of different particle size and a special resin without solvents. The blend obtained from the mixture allows the coating of decorative elements made of polystyrene, with excellent results.

The result is the creation of light yet resistant architectural elements, for indoor and outdoor, designed to last over time
