The following photos are from a repair in a retail location. A display was removed and some anchors had damaged the concrete. The repairs varied from feather edge to about an inch. The entire area is to be covered later, therefore color was not critical. The repair material chosen was R3. This material can be applied from feather edge to 3”.  It also reaches 3,000 psi in 3 hours so the repair area had minimal down time.
