Edco grinders are designed to repair damaged slabs, remove deteriorated coatings and prepare surfaces for overlays. Various accessories enable operators to use the grinders to eliminate high spots, paint build-ups, rain or trowel marks, manufacturing residue buildups, or to return concrete to a smooth, clean, level surface. The grinders are available in 11-, 22- and 36-inch working widths with power options that include gasoline, propane or electric.
