EZ Nano Seal LLC and Ninja Power Soft Wash LLC

They were on time and completed the job in two days. However, When the two young men were applying the sand and the sealer, one of them was continually on his cellular telephone while he was working. A supervisor came out the following day and did notice there were a few areas where the fine sand was not applied correctly. There were also streaks which were visible but stated once the sealer cured they would not be visible. It is now four months since the job and the streaks are still visible where the sealer was not applied proportionally and some areas appear to need to be sealed again. I have attached two photos. One shows some of the streaks, the other shows one of the areas where the fine sand was not properly poured to fill the gaps between the travertine.
