Instead of replacing the damaged concrete patio shown below, we spread a cement overlay on top of the damaged concrete. First, we prepped the damaged patio by removing all loose material that would prevent a solid bond. We then applied a glue and 2 applications of cement. The cement overlay is approximately 1/2 inch per application. After waiting a day, we then saw-cut the diamond shapes into the 1" overlay. Lastly, we cleared the saw cutting dust and applied 2 coats of a high gloss clear concrete sealer. Looks can be deceiving, the work appears like a completely replaced concrete patio but for less then half the cost.
