Overhang??

[smurf21]

Same as john for me its classed as ceiling.... but if it is to be tiled as dave says backerboard.. or at the very least skim the tile aswell as the ceiling for a better adhesion.

As for the full tile at the ceiling line it depends on the rest of the set out ie bath /shower etc. but when you come to the ceiling/wall intersection just cut to ceiling and use the offcut for first tile up the ceiling slope..

Hi Mozza,

I've done a job exactly how you describe, recently. I will try and find some pics to illustrate (but wont be 'til tomorrow).

But.....
I used plasterboard as the substrate and back skimmed the tiles (they were only 200 x 250).
I was working with white tiles and white grout (so the non matching grout lines were not so obvious).
I had to carry 2 mosaic borders around the room so "opened" up the grout joints to ensure that everything flowed.
I set out the room for best possible cuts and cut tiles along the joint line where the pitch started, this gave me the option to "extend" the tile slightly to keep control of grout lines, without looking wrong.

Don't worry, it's easy to do if you apply common sense and you eye.

Allways backskim the tile on a window head, gravity I believe

Right, I've just found the pics, but they are really bad quality :incazzato:, so hopefully these will give you some idea of what I was on about.

That's exactly what a meant Cpt. Slow, steeper angle but the same situation, thanks for the help and the pics also!

i also need to tile an overhang (approx 45 deg slope) but the tiles are pretty heavy (450 x 450 porcelain floor tiles going on the walls!). there are only about 8 tiles going on the overhang though.

i have advised the client that it isn't an ideal situation and to avoid possible injury/damage, the overhang should either not be tiled (which they are against) or to physically screw in each tile for added security with a central screw and discrete cap.

i also intend on preparing the area with a good quality tiling board.

anything else i should look into? does anyone know of some good looking fixings that i could use?

Mechanical fixing is certainly a good safety option.

What adhesive are you planning on using and what trowel size?

If the walls are good and you are fixing to tile backer boards then I would be tempted to use Ardex x77 adhesive with an 8 or 10mm trowel. Application method would be to trowel the adhesive onto the backer boards and also fully backskim the tile prior to very firmly pressing the tiles into position. X77 has a superb grab and you will find that the tiles will stay where they are supposed to, IMO.

If you are uncomfortable with relying purely on adhesive, then mechanical fixing would be the sensible option.

Good luck.

thanks for the advice Captain. I'll look into the adhesive you have recommended.

regarding trowel size, i'm not a regular tiler (though i would humbly say that my work is generally of a very high standard) and therefore find it easier to lay tile by tile, buttering each tile with the necessary adhesive to ensure a plumb and flat wall.

i have taken on board your suggestion of trowelling wall and tile. do you think that the adhesive alone is enough? i will most certainly be using a backer board and have just weighed one of the tiles that will be going on the wall - just under 5kg each!
