This is the main room of a 900 sq. ft. residential finished basement. The photo at left shows the condition of the concrete at the outset. The photo at right shows the floor after first cleaning, then grinding to shave off fibers used in the concrete mix, ngraving out indelible chemical stains caused by the carpenters and painters, and finally scoring decorative cuts to balance the existing control joints. After the surface prep was done, the floor was stained using Artcrete's "Onyx" acid stain. The first two photos below show the relatively flat finish of the floor after sealing with Decosup's solvent-based acrylic sealer. The last two photos show the added luster and gloss from several coats of Spartan's On 'n On floor finish.
