I posted some time ago about how my PB messed up the acid wash process and scratched all our glass trim tiles, which had to be replaced. Well during the acid wash it seems they messed up something else. As I was watching the two guys working I noticed a water was left pooling in the shallow end, as the deep end was filling. I thought nothing of it. We had to drain the pool to redo the trim tiles, and that's when I saw a huge whitish stain where that water had been. I brought it up to my PB, who said "you won't see it when the pool is full". Well of course, now that the pool is full of water again, I see it (looks like a big "8"). More so when it's getting darker toward the end of the day. Is this something I'm supposed to live with, or completely unacceptable? My PB said it wasn't unusual for this to happen (leave water pool up) when acid washing. I don't know if I can believe him, how could I? I'm not an expert. BUT, this stain definitely bugs me. Even more so knowing they damaged our trim tiles. That's a lot of mistakes for one job.
Attached are some pics.
