Had pool deck poured 1200 sq ft broom finish. About 80% happy there are some spots that are to rough like the broom was dirty with concrete or something. Anyway its 5 days old and when i sweep or drag foot still getting lot of liitle concrete pebbles fly off and get dust with bromm. Concrete guy says this is normal it will wear down with use, and water. Does this sound normal? sounds like i will be spending first season dealing with concrete pebbles in pool. is this just something that happens with a broom finish due to the ridges?
