Concrete Polish: 32,000 sqft. 800 grit gloss finish, with custom gray dye. At our clients request, our expertise was called upon for 18,000 square feet of dyed concrete polishing at the Nordstrom’s Rack in Seattle. Our professionals applied custom colored concrete dye for accents to go along with the industrial look of the concrete and carpet tiles. The final polish at a 400 grit polish was sealed and protected with a Prosoco Polish Guard system.
