START TO FINISH PROCESS: On this project which was completed back in 2001, our Certified Applicator started with a 50+ year old slab in a building that had been constructed as a veterinary clinic, and was now being converted to a wine store. The General Contractor had to perform saw cuts and do pour backs for plumbing and electrical; the floor was stripped of old VAT; and the final project was to be a combination of RetroPlated concrete with acid stained graphics. With RetroPlate, NO TOPICAL SEALERS ARE REQUIRED OVER ACID STAIN. You will note from the photographs, that “ghosting” of the previous tile pattern will be present, even after the diamond grinding. Following the initial grinding, the acid stain pattern was laid out with a specialty tape, thus eliminating the need to provide decorative saw cuts, along with eliminating the need for joint fillers. Bottom Line: The customer received a beautiful, polished concrete floor with great appearance and minimal maintenance requirements!
