another porcelain tile impregnated with grout dust and what have you problem

[Buffer]

Hello there ~ we had a new bathroom fitted last week ~ and can report another porcelain tile impregnated with grout dust and what have you problem. When searching the net for a solution (as nothing we tried will get rid of the staining) we came across this site ~ and stickers on the boxes of tiles indicating that they should have been sealed before laying and grouting. So, with the advice on this site we’ve just ordered LITHOFIN ABRA-CLEAN, some CEMENT-AWAY and PROTECTIVE IMPREGNATOR.
Could you help out with some advice? The grouting the fitter has used on the floor tiles is crumbly, looks generally rubbish and needs replacing. (The walls aren’t much better but at least the rubbish grout distracts you from the crooked tiles).
We’re going to have a crack at digging out the grout on the floor tiles and replacing it. So, our question is ~ should we clean the tiles, seal them and then try and remove the grout? Or, should we take on replacing the grout first and then clean and seal the tiles and re-grout?
Oh, could you recommend a good charcoal coloured grout too?
Thanks very much.

Hi and welcome....sorry to hear you have had an unsatisfactory job done..

I would remove any cracked/crumbly grout firs before you try to clean them...

Use the cement away first but try it in a not so conspicuos area first before doing the whole floor to see if it helps...then if the this doesn't work then go witht he abra clean and a stiff bristle hand brush and scrub to agitate...thenn clean off with clean water and leave to dry before using the sealer.

Have you tried contacting your tile fixer to sort this out

Thanks very much. The tile fitter issue is to be resolved. One school of thought is we challenge him to comment on his work, see whether he'll acknowledge it's a mess and take it from there. The other school of thought is that it'd be better if we didn't put him in a position where he could bugger anything else up and/or cause more stress ~ and we'll invest the time and care necessary trying to bring it up to an acceptable standard. Ongoing discussion is that.
