Product Description

Plaston HCS Base Coat is a **0% acrylic polymer based cementitious material, reinforced with chopped fibres, and specially designed for application over extruded polystyrene insulation board. This factory blended material ensures uniformity of application and enhances the performance of the Wall System. It cures to a tough, durable, and weather resistant coating. PLASTON HCS Base Coat can be used: As the base coat for Plaston EIFS in which the reinforcing mesh is embedded.
