Finished Basement Concrete Floor After Cleaning In Prep For Acid-Staining

This is the middle, "recreation" room of a 2,300 square foot residential finished basement.  The cleaned concrete floor (above left) was acid-stained after scoring an 18" wall border around the perimeter of the room, the main stairway, and the 2 adjacent hallways, and offset rectangular tiles in the middle of the room (above right).

We had to aggressively sand the floor beforehand to remove extensive paint spattering, which had given the concrete a "white" appearance (photos above left and below left).  This sanding, instead of the traditional "detergent scrubbing", helped create a fantastic mottling effect from the stain that enhanced the slate-like appearance of the rectangular tiles.

The colors used for the tiles and border were "Weathered Bronze" and "Padre Brown", from Scofield.
