Pool service?
Yeah, tried that. This stuff is HARD. I burned through a whole block of pumice in three feet of tile and I've tried several chemicals also. I'm spent on this project. I need help.
Only way to get that off is to have someone come in and blast it off. Had it done on the pool in Fountain Hills, cost about $300
