We used Flintstone to seal our concrete paver driveway, and the job they did was totally unsatisfactory. They failed to follow the manufacturer's instructions when applying sealant, applied the sealant before the driveway was completely dry, missed adding sand in areas, and sealed over oil spots. The result is poor appearance and stability of the concrete pavers. We had to advance them the money to buy materials as they had no credit with the supplier, and paid them when the job was finished at their instance with the understanding they would come back and fix the problems. Boy, were we wrong. It has been six months since they left, and aside from a brief visit (mainly to be shown where they missed adding sand), all we have received from them is excuses.
