This is a fully polished concrete floor we created for this customer. We started by filling the expansion joints with polyurea. We then started grinding the concrete to remove the glue from the carpet tiles. After repairing the concrete we continued to polish the concrete up to a 1500 grit finish. The concrete then had a guard type concrete sealer applied that was burnished to a high gloss finish. They are using the room as a testing lab for their facility.
