hello everyone me needs some advice please,i am tiling a bathroom, floor to ceiling with 600x600 polished porcelain tiles.1 the tiles need cleaning on the reverse side ,they have a protective "oil"on them,what should i use? 2 do i seal them prior to fixing to walls? thanks for any replies i get
the tiles are going onto a newly cement rendered wall i was going to use BAL SBR to seal the walls the wall has dried out for 3 weeks thanks again

i would seal after fixing, just the way i prefer, you say oil or is it transit wax

not sure mate bloody slippery stuff tho

Never found anything as described in 38years - so I'd take them back.
Tiles should be clean and dry before installation.

thanks for replies chaps but if its transit wax what should i clean with cheers

i no i sound like a right newb,but have done lods of ceramic tiling never done porcelain cheers chaps

I've not heard of anything being applied to reverse of the tile before. I'd normally use LTP Grimex to remove transit wax, LTP Solvex may work on the protective oil you mention also. Your best bet would be to contact LTP direct and see what they recommend.

oh the reverse of the tile sorry i missed that,

i once bought a pallet black porcelain tiles from china when we opened them up they were coated with some sort of oil, had to soak them in soapy water when scrub them clean abit of a night mare didnt buy anymore,

cheers for all the replies i`ll crack on with the grimex and let you know how i get on

Hi there, Chinese manufactured tiles have
wax both sides!!! If not removed.. Disaster!
