Concrete Polish: 32,000 sqft. 1500 grit gloss finish, with custom gray dye. At our clients request, our expertise was called upon for 32,000 square feet of dyed concrete polishing at the Nordstrom’s Rack in Bellevue. Our professionals applied custom colored concrete dye for accents to go along with the industrial look of the concrete. The final polish at a 1500 grit high gloss polish was sealed and protected with a Prosoco Polish Guard system.
