Need Advice - Black marks in Gray Plaster
My pool was plastered gray and we have several "black marks"...more than 50 throughout the pool. I have read that this is common from being poorly mixed. Some friend's of ours have the same gray, used the same builder but ended up with only 7-10 black marks. I can live with it but very dissappointed.
Is this something i should complain to the builder about? I highlighted this to the builder before in an email but he never mentioned anything about it.
Just looking for any feedback and thoughts.
