Sloping ceiling.

[enduro]

Got a job to start next week for a builder, and the client has a shower in here loft conversion that has a sloping ceiling and she wants it tiled...But the tiles she wants are 600x600 15mm thick granite :yikes: The ceiling has backer board on it ready to tile. There needs to be 4 tiles on the ceiling, and I'm not too happy putting these buggers on a ceiling in a shower her kids are going to use. I have told her im concerned about this. What would ou do?

Thats not a great situation to be in.you'll need the highest grab ability of adhesive known! The boards will have to be well screwed to the rafters or whatever.the weight issue doesnt help either.pity some sort of discreet clips maybe couldn't be used.

As long as you solid fix, then no probs..there needs to be no flex in the timbers...it is just the sloped bit isn't it..?.

Think of it this way... How many big windows heads/ cubby holes and niches have you tiled and the tiles are still there...the correct fixing/prep and it is fine in a small area like that.

Our US friends do this type of fixing day in day out.

600x600x15mm GRAVITY..mmmmm i would dodge this or mechanically fix, but to mechanically fix you need to know what is behind the substrate in order to fix correctly....just an opinion!

Heres a thread from a while ago and some good points on tiling ceiling.

Hi mate. i have tiled a couple of ceilings now but only small ones in the top off shower areas and mainly in stone mosaics, the biggest bit of advice would be to strengthen the beems as much as posible.
Any Qs on how i do it pm me.

What about steam rooms and similar, they are tiled on the ceilings, get a good quality adhesive for the tiles in question and ensure 100% coverage, you should not have any problems. You could use supports if you want to but thats a personal choice, I have done so many that I know the tiles will hold if the surfaces are prepped accordingly.

iv'e mosaiced plenty of steamroom/prep rooms ,but mosaic is usually light in waight

am i the only one that 600x600x15mm is too much...each tile will be 15-20kg each as it granite!!!

if i am wrong then great!!!!!

 

[sranners]

I recon it will hold, im not shour if adhesive companies do but is it not about time they started to state what they will hold on a ceiling, ceilings in the states and canada are done all the time,
prep prep prep.

Dave you are right regarding mosaics etc but if the specified tile is an oversized tile then you have to work with that spec, Modern day adhesives will hold the tiles in question, it does not matter how big the tile is, it could be 500x500 or 1500 x 1500, its all relative with regards to adhesive and size, some need support before drying and some do not. Prepared surface's are the key ingredient's

As you might have read in the thread that Whitebeam posted, we set tile on a lot of ceilings here. The key elements to this are the framing specs for the rafters, how the cement board is installed, and how to use setting material properly.

The fact that the tile is over a half inch thick and 4 sq ft per tile really isn't the issue. Think of it this way...we would all feel OK installing this if this material were cut down to 6" squares, right? Taking the tile size up to 2' X 2' only means that you need to keep good coverage going on a larger scale. The epoxy that I mentioned in that other thread is good for slabs up to 2" thick. The stone will fall apart before that epoxy will lose its bond.
