EDCO Grinders come with a multi-accessory disc that can be loaded with EDCO’s long-lasting Dyma-Serts, Strip-Serts, grinding stones assembly to remove rough finishes, flatten uneven areas or clean concrete slabs of sealers, paints or mastics. Grinders can also be used effectively to level uneven joints or high spots of 1/16 to 1/8 inch. EDCO Grinders provide contractors a smoother finish than scarifiers or scabblers. Three Stones are required to operate this machine. The portable single-disc grinder is ideal for grinding smaller areas. The portable Single-Disc Grinder will grind approx. 200-250 sq ft/hr with EDCO Dyma-Serts.
