Sealant for Ceramics

[rich hand]

I have been asked a couple of times recently if there is any sealer suitable for ceramics. The reasons were to fill in the ridges and holes to stop dirt getting trapped and also to give extra sheen to a dull porcelain floor.

I know aqua mix has a high gloss sealer but it seems it is only suitable for rough ceramics, the tiles in question are not rough; also, one of the floors would require a matt sealer not gloss.

Sovereign Chemicals do a very good all purpose Sealer for Stone , Porcelain and Ceramics. However, it is a mat finish only I believe. Its called 'Sovereign Stone Sealer'

lithofin PORCELAIN impregnator, but porcelain is not a ceramic!
common misconception!
