Stain & Polish Concrete: 30,000 sqft. 800 grit gloss finish with Moss Green Dye. Our expertise was called upon to polish 30,000 square feet of high-end concrete polishing at an Asian Market in Bellevue. Our schedule was accelerated so we brought in one of our 96” wide 3-headed floor polishers to speed the project up. The schedule was accelerated by 3 weeks and the client was able to gain the schedule delays back caused by other trades. The concrete was polish to an 800-grit finish with a Moss Green Dye and the Retroplate system. It was sealed with RetroGuard Sealer for stain protection.
