This is the main room of a 900-square-foot residential finished basement of a remodeled home in the Lincoln Park neighborhood on Chicago's north side. The photo above left shows the condition of the concrete at the outset of the project. Above right shows the floor after detergent cleaning and grinding to shave off fibers used in the concrete mix.
We also made several decorative saw-cuts in the floor to balance the unsightly, existing control joints and then acid-stained the concrete a dark "chestnut" brown, using Artcrete "Onyx", that would match the basement's wood furniture and cabinetry. The photos above show the matte appearance of the floor after applying the solvent-based clear acrylic sealer.
We then applied several coats of a clear acrylic floor finish for added protection and easy maintenance. The last two photos above show the luster, depth and gloss that floor finish brings to acid-stained concrete after it has previously been sealed.
