More Tips:
test a single tile with the sealing process, some of the deep colours ( Burgundy, Navy blue ) bleed into the background colour if sealer is applied too roughly, best advice is to test your tile with the whole process, I've found L
ithofin products to be the best on these naughty tiles. I would suggest a good Daywork rate or £75.00 a metre minimum, as you will be coming and going with washing, sealing, sealing, waxing, grouting, washing etc.etc ( not in that order ! )
don't forget to cobblewax (
lithofin ) them at the end ( which is a process that these tiles will need twice a year, as traffic wax ! )
Lastly: thoroughly clean your wet cutter, use water very sparingly, just enough to cool the blade
Ps: They're a pain, allow enough time, and then add some more for good measure
