This job required a lot of edge work. Concrete Floor Systems followed the same grit sequence to polish the slab’s edges. Instead of polishing the edges with the Prep/Master, the crew used a handheld grinder. “We dropped to medium cup to wet grind the edges,” Weaver says. “The concrete was hard and we had to work to get the edges.” This allowed them to make the edges blend before polishing the edges.
The dyed and polished floor was allowed to sit for one week before Concrete Floor Systems came back with a high speed burnisher to burnish and finish the floor.
