Marble tiles on sloped ceiling - TilersForums.com

[Adam Heron]

Hi guys!

I am doing my first ever bathroom project and am after some advice from you true professionals.

I intend to tile half of a sloped ceiling with 610x305 marble tiles. There will also be some tiling onto brick walls. I'm not sweating about the walls so much, just the ceiling! I have spoken to tile giant, topps tiles etc with very limited response, hence why I'm now here.

"No one has asked me that in 20 years mate, I'll have to speak to the manufacturer!"

Have seen some previous advice of hardiebacker screwed to the joists, tiles adhered individually and supported for 24 hours. Would greatly appreciate any thoughts and input on this guys. I'm obviously looking at spending some serious money on this marble, doing it correctly and hopefully looking like I've had one of you guys do the job for me!!

Yes... I'm ambitious!

In terms of best tile adhesives, top quality mould resistant grout etc, what are your views and opinions on this? I'm certainly not a tiler, but and engineer with an eye for detail. Want everything to be done to the best possible standards. I'm not just prepared to walk out of a store with materials that I have been told are the best and suitable for the job. Need advice from professionals who actually do it for a living!

Greatly appreciate any help and input on this guys...

Cement board will be best to use but you will need a very strong adhesive and they will have to be solid bed fixed using an S2 type adhesive or even a 2 part one. (like Granirapid for instance)

If you are cutting these with a wet cutter, then you must ensure the back of the tile is completely dry before fixing to the adhesive.

Hardie backer on the ceiling would be perfect, an s2 like Tilemaster ultimate would be my choice. As long you you solid bed then with the correct methods you won’t need any props, and they are never gonna fall off!

Thanks Tom. Could you elaborate on the solid bed method you would employ? Particular trowel etc? Any advantages of 2 part over s2? Cheers.

Thanks Localtiler

Solid bed method, tips etc would be appreciated. What thickness or trowel? Is backbuttering required? Cheers

Ha! That did make me chuckle!

I may be an engineer, but I'm no tiler John! If I'm heading for a 6d grilling I'm all braced!

Here are some tech sheets for you read adam.
Ak25 is an S2
Mega-rapid is a two part adhesive, maybe this will help you understand the difference.
With the mega rapid, the fact that it is water free, will help prevent moisture issues with the marble.

Nice one 3fall

The megarapid looks like a good material for the job. Any additional advice or pointers when working with this adhesive? Cheers

No, only that it has a genuine pot life of 3 hrs. However, if you expect this might take a while, reduce the amount mixed at once, and make sure you weigh quantities correctly, as per ratio.
I’m sure I don’t need to remind you of that tho.
Otherwise you’ll be throwing away more than you use.
It’s also important to allow the adhesive to slake before re-mixing and using.
