Ceramic tiles going blueish

[TPW]

Why would my ceramic tiles have a blueish tinge?
They are a 450x 450 beige tile with a red base fitted in a wet room and they were sealed with lifofin stain stop.
any help would be great.

Why have you sealed a ceramic tile ?

 

[kilty55]

did they turn blueish when you added the sealer

you dont need sealer for cermics

i was told to by the supplier, is this wrong ?

Ceramic tiles aren't really suitable for a wetroom floors and sounds like they may be absorbing water which is making them discolour.....

 

[Gazzer]

Did you use a grey adhesive ? Are you sure its a blue tint and not just the lighting ?

 

[kilty55]

yes if they are ceramics you dont need any sealer

at what turn did they turn in colour

 

[Gazzer]

I would say its water getting through the grout and then soaking the back of the tile. Is it generally in the wet area ?

 

[Gazzer]

I see you have asked the same question before and I feel you will only get the same answers.

The more i have looked in to it the more i find out that ceramics dont need to be sealed, i was told that i should seal them by the tiler to be extra safe! could this be the cause of the discolouration?

No the sealer wont do anything. If the tiles are glazed you should not need a sealer.
The only thing I could suggest and it would help if you answered our questions is...
Does the blueish tint fade if the shower is not used ?
If so then if you could not use the shower until the tiles return to natural colour and then seal the grout joints with a grout sealer. That is my only thought of cure . Really glazed ceramic tiles are not suitable for this kind of installation IMO.

I too would have thought that it's the water under the glaze due to intermittent wetting they'll never really get fully dry. Ceramics are not the best choice for wetrooms and even just shower area's if it's used a lot.

 

[TPW]

do you think it is worth removing the sealant some how and seeing if that works? if so how would i remove it ?

 

[Gazzer]

I wouldnt even think there is any sealer on the tiles. if they are glazed it will have no where to seal anyway.
