Hi guys,
got some stains appeared on some joints (not all) on honed grey slate (600x400).(see attached pic). clean water was used to wash when fixing and bal rapidset flexi was used to fix. the stone is fixed but not sealed or grouted yet. I thought maybe the staining could be removed when washed with grimex prior to sealing and grouting?? (not tried this yet)
any ideas on causes and solutions?
Thanks
