We just had the first phase of pebbltec ocean blue pool plaster completed today and an area of gunite efflorescence (was a line of white dripping down from this area) appears to be showing through as a patch of darkness. Will the acid wash/brushing resolve this issue, or should I ask to have it refinished? Thanks in advance.
Here you can see what it looked like before the pebble:
