job coming up in slate 300x300 preferences to sealing either before grouting or after or before and after grouting ?? also is the grey addy still ok to use or white ? will a rapid set flex be ok as long as i keep them clean along the way and grout line free of any residue and adhesive??any infor would be great 🙂 doing a job in travertine 100x300 i sealed these prior to grouting came up nice no issues with a white addy is this the same sort of thing with slate ?
