Looks like iron oxidation. I would wait a few weeks until it is totally dry. Sometimes it will disappear. If it doesn't, you can use a screen to remove it if the tile is honed

Hello Partners,

 

So we have some sandstone that was laid on a wed. and finished Friday. It was hosed down on a Friday and returning Monday it was really stained. 1 tile has been cleaned with a hydrogen peroxide, but it started to return. The back was also done but not hosed off that this didn’t happen to. They have about another 3000 sf to install and they don’t want to have this happen with all of it.  I will include pictures any info would be great.

 

 

Thank you, we appreciate your business!
