Help Please ....Unmovable grout residue.

[jadsap]

Have just moved into my new home ,beautiful Italian Platinum pure check metallic 600 x 600 tiles (grout Ardex Flex FS grey) fitted in the bathroom that have now turned from black to a strange dusty grey/white patchwork effect.Have tried EVERYTHING to clean ..Lithofin Cement residue remover,Lithofin Intensive cleaner,Lithofin Wax off...all to NO effect,tiles still have white speckles .At my wits end with this as these are very expensive tiles (6 weeks old !!), does anyone know of anything that may help ?
Cheers.

what biscuit are those tiles...?

 

[Spud]

I have it on good authority you should never use acid wash with metallic tiles even metallic glazed porcelain as the acid discolours them

Gary....looks also like patching through the biscuit from adhesive don't you think..?

Haven't seen those tiles before..just wondered what biscuit they were.

cheers tel..

i have used some wall ones like those but they were white biscuit...


So. paul..these shadings were there before you used any cleaner..? and just appeared after how long..?

They appeared after we had moved in and washed the tiles with the normal Lithofin cleaner.One suggestion was that the grout had not been extensively cleaned from the area and it being flexible had a polymer ingredient,this once locked in with the Lithofin protective impregnator is when it started to show ?

You have lost me here! What is normal Lithofin cleaner exactly? What do you mean by Lithofin Protective Impregnator? It was my belief these tiles do not require sealing!

Lithofin conditioning cleaner for regular cleaning then every 3 months follow up with Lithofin Protective impregnator which I quote "renders polished,matt and structured porcelain tiles stain resistant and greatly facilitates every day cleaning " .....so it says !! :mad2:
