This is the main room of an 1,150 sq. ft. basement floor.   We installed a decorative concrete overlay and then acid stained after removing black cutback tile adhesive by concrete grinding, and performing 225 lineal feet of concrete crack repair.  The homeowner had encountered flooding problems and had to remove the existing carpet and tile.  The acid stain color is a mix of Walnut and Antique Amber from Scofield's Lithochrome Chemstain designed to give the floor the look of wood.  The concrete overlay was decoratively scored (using the "contemporary" pattern here) to convey the impression of inlaid sections.
