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 ?

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?
