Brick slate in a wet area

[redlee]

I've got a shower to do with one of the walls having this type of brick slate (apologies for the cack picture best i've found so far)

- these tiles can't be grouted so water will get to the back of them, should i seal the whole tile?
Cheers
Lee.

Might sound a stupid question, why can't they be grouted

 

[redlee]

It's not a stupid question because the pic i've linked to is too small to show clearly but each 400x100 tile is made up of about 9 seperate blocks which are all a different thickness and all very rough. They aren't meant to be grouted and i reckon nigh on impossible to clean down.

can't see the picture, but like anything in a wet area, it's the substrate which needs protecting, not sure about the sealing but if as you say they can't be grouted, i imagine this means they just butt up against eachother?.... I would say the area needed to be tanked first then the tiles are just a feature..

Water will creep thru the joints, tanking would be an under statement to cover yourself

 

[redlee]

Sorry fellas should of made myself more clear, the wall has got a wet room membrane on it the question is more regards the sealing, i will obviously seal the face but as water is free to get to the back of the tile should i seal them all around before fixing?

Will try and sort a link out.

But what you find is you can scratch that itch in the middle of your back just by leaning against them!
We did a feature strip x 2 in a walk in shower/wet room earlier this year.
I believe our client bought this slate stack from Porcelanosa at some ridiculous price but it was amazing to look at and must have taken some time to make up.
When you look at the back of the 'tile' strip the pieces are so close together there is no possibility of grouting between the strips.
So you have to make sure that the wall is 'tanked' and the back of the tile is filled with waterpoof adhesive - this way any ingress will not affect the substrate.
On completion and when fully dry - seal the slate with as many coats as will be accepted.

know what you're saying whitebeam, but theoretically, tanking should be able to take the water no matter what the face covering is, water is going to creep thru eventually grouted or not, hence the tanking..

Yep Porcelanosa supplied these as well, so just seal the face and exposed edges no need to worry about the back?
When you say waterproof adhesive would standard 1 part flexi cement based be ok??

I have a photo somewhere of the one we did - it was 2 feature strip about 300/400mm wide - I'll post it later!
I would use a cement based fast set fexible and if you can seal the edges before fixing do - but not the back!
One thing we found as they are 400mm long and interlocking - stagger the joints between the rows of 100mm widths - as that joint will stand out as being a straight line otherwise.

Cheers John, will do, have been on a job with these in a larger format so know what you mean about staggering the joints luckily this is a full wall so will be easier to hide than on a panel.

my missus wanted those (altho I can't see the pic) as a feature wall in our bathroom, I shot her my "don't even think about it " look:20:

So would i at about £100 p/m, they look gash as an idividual tile but on a full wall or a decent strip they do look bobby dazzler, does anyone know if you can get internal/external corners for these?
