2nd grouting , is this common?
Today my contractor finished the grouting. After they left, I noticed a lot of pinholes, cracks and missing in the grout line. I asked the owner about it and he said the workers usually the 2nd grouting next day to fix those problems. From my understanding, they should do in the first grouting without problem. Do you think they do poor job? Is it ok to fix those problem just over-grouting? I hired the high rated contractor, so I now have mixed feeling. Thank you.
