Wet biscuit

[trevb78]

Hi all,

Another newbie error!

I'm on the way to finishing all the tiling in the bathroom. Some of you may remember - I completed the shower first to keep the bathroom running.

I have just discovered a few tiles that have now got a blue hue - I believe this to be from the biscuit getting wet.

The two tiles on the left hand of the picture, in the lowest course to the shower base, is mounted to a solid wall, covered in Ardex wpc before tiling. The other two tiles, one of which is the lowest course, then one up, are mounted to a Wedi boarded stud wall. It is a corner shower - I don't think there are any leaks in the pipe work.

What are my options?

Could it be a grout issue?

Can I dry it out with a dehumidifier if I remove the grout?

Many thanks!

Trev

different batch of tiles?

What surprises me is if there was a leak or ingress why is a whole tile changed colour not speading onto the surrounding tiles.

I thought that at first, but didn't spot a problem when I first installed. Then I dug out a photo from the time...

 

[White Room]

Where did you buy the tiles from...

 

[trevb78]

CTD tiles. They are Residence Ceramic blanco brillo I think...

I'm thinking the same as you mark. Out of interest what was behind these two tiles?

In the images- the left is the solid wall with Ardex wpc. The right is the wedi board stud wall.

Evening all, quick update...

I went to the tile shop today - they are going to send round a technician I believe....

Any way, been cracking on today...

You lost the flow above the door frame....

 

[trevb78]

It was a decision I didn't make lightly!

 

[trevb78]

Did I make a bad decision?

Did I make a bad decision?

Yep!

 

[trevb78]

What should I have done???

 

[Qwerty]

What should I have done???

Continued the brick-bond layout along the wall above the door and not stop the layout then start again at the door frame as you have

 

[trevb78]

What should I have done???

 

[trevb78]

But I followed the pattern along - just cut down the one above the door to suit? This is so the grout lines are constant...

Not arguing, just not entirely sure!

 

[stusgsx]

Those tiles are a different batch!

 

[trevb78]

I did think that, but I would have noticed on install or soon after! Plus, the pictures tell a lot!

 

[trevb78]

Just fallen in to what you mean above the door - L shape should have been around the door frame! Doh!!

Never a good idea ending with a full tile because ceilings normally run out...

 

[trevb78]

Its not too bad - I had it skimmed recently... I think it looks ok. For my first full room!

Judging from the pics you'd think its got to be down to the tiles, which could be replaced by 2 fresh tiles in an hour, but if you've got a rep coming out then let him decide best course of action and don't let him fob you off.
I'ts never a good idea to have full tiles to floor and ceiling, not unless you know exactly where your high and low points are, can't remember coming across a bathroom when the floor and the ceiling were 100% level, if its your first full bathroom in your house and your happy crack on.

 

[radim]

put level on tiles above door. if level is rocking you made right thing.

 

[trevb78]

The rep is coming round on Wednesday....

As for tiles above door - I might replace them a bit later. How bad will the plasterboard behind be?

Re - tiles changing colour.
With I lighter colour tile you will not notice they are different batches till they are grouted then it stands out like a sore thumb.

When you purchase your tiles were there any loose tiles not in boxs or any broken boxs with tape round them..?

 

[trevb78]

I understand, but the third picture shows after grouting...

Why does it always happen that you don't notice shade problems until you buff up the tiles??
In my younger days I did get get caught out with batch/box problems......I didn't cotton on to customer when she said that the DIY shed that she got the tiles from told her that they had to amalgamate boxes from 3 different shops for her order,hence.....3 different batch colours....DOH!

[Andy Allen]

Thats what were saying you may not notice they are different batches until its been grouted....then it stands out...
Did it myself once tiled whole bathroom looked perfect till I grouted it then you could notice some tiles were darker than others..

 

[trevb78]

Got it - but the third picture is after grouting and no colour issue....!
