When the exterior finish is specified as rib, rake, sandblast, water-washed, acid-etched, imprint, exposed aggregate, as examples, the interior building finish is the steel form side of the panel. However, when the steel form smooth surface is turned to the exterior, the interior finish can be a broom texture or troweled finish. In either case the steel form surface is high-density concrete and may contain small pit holes, which may require patching by others prior to finishing.
