That does look like a problem with the grout or it could be from underneath. I would scrub with a light acid and see if it comes back.

Was this salty water?

Subject: Absolute black honed water damage

Hi partners,

Looks like efflorescence from water damage. There was carpet over this and a pipe burst. I think it’s absolute black honed threeeights inch tile. My guess is I can grind it off and re-hone it. What do you think?

Thank you,
Chris Santospago
