EPS / ICF / Polystyrene Block Construction
Description

The StoArmat Miral Plaster System provides protection and finish for EPS/ICF block construction. The EPS/ICF Blocks are base coated and levelled with LevelLite to provide a thick solid plaster base for additional reinforcement: StoArmat plaster plus StoMesh.
