Sloping bathroom/ceiling

[rj1884]

Good afternoon all. Went to look at a job today. See pictures. The customer wants to remove existing tiles and replace with new tiles covering the same area as the existing tiles do. He seems to think that the person who tiled the existing area was a DIYer. My first question having not tiled a sloping wall before is is that the norm that the horizontal grout lines don't match up by that much.
The walls are plasterboard which more then likely will have to be repaired once the existing tiles are removed. The customer is looking at using 60x30 tiles on this area which I think maybe to heavy to fix to that particular wall. Can you give me some advise on the way to go about tiling this sloping wall/ceiling in particular the way of getting them to stay on the wall without them moving whilst the adhesive is drying. I normally use ardex adhesives and was thinking of X77.

Many thanks in advance..

Oh ffs ali, i didnt go to school , whata that mean ?
Is it a witty remark or some Einstein relativity theory ?
Come on im off out shortly ,I NEED TO KNOW

Of course the old Pythagorean theorem,here's my thesis on Pythagoras and his theory's from my days with the jolly boys at eton

In mathematics, the Pythagorean theorem—or Pythagoras' theorem—is a relation in Euclidean geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. The theorem can be written as an equation relating the lengths of the sides a, b and c, often called the Pythagorean equation:[1]

where c represents the length of the hypotenuse, and a and b represent the lengths of the other two sides.
The Pythagorean theorem is named after the Greek mathematician Pythagoras (ca. 570 BC—ca. 495 BC), who by tradition is credited with its proof,[2][3] although it is often argued that knowledge of the theorem predates him. There is evidence that Babylonian mathematicians understood the formula, although there is little surviving evidence that they used it in a mathematical framework.[4][5] Also, Mesopotamian, Indian and Chinese mathematicians have all been known for independently discovering the result, some even providing proofs of special cases.
The theorem has numerous proofs, possibly the most of any mathematical theorem. These are very diverse, including both geometric proofs and algebraic proofs, with some dating back thousands of years. The theorem can be generalized in various ways, including higher-dimensional spaces, to spaces that are not Euclidean, to objects that are not right triangles, and indeed, to objects that are not triangles at all, but n-dimensional solids. The Pythagorean theorem has attracted interest outside mathematics as a symbol of mathematical abstruseness, mystique, or intellectual power; popular references in literature, plays, musicals, songs, stamps and cartoons abound.

I work for a Hotel/pub chain all the kitchens, toilets and bathrooms have the ceilings tiled , I must of done well in excess of 500m2 ,my biggest was a kitchen ceiling of 60 m2 I try and go for white 150 x150 or 200 x 200 I would not like to go any bigger.

It's a matter of opinion each to their own unless your setting out is absolutely perfect it would be hard to link that slope up to the walls if it was me I'd consider keeping the slope independent to the walls and make a feature out of it and mosiac it but it's hard to give advise without looking at it but with the right walls tiles mosaics on that slope would look ok I think

It is impossible to do with the same size tile.
If you were fixing a natural product. Say Travertine you could get big tiles to cut down. But you can't do it with your main wall tile.

C2=A2+B2

yes I totally agree you couldn't link that up well I couldn't anyway

As Ali says its impossible to match up those grout lines,
It can't be done unless you cut the tiles.

I've just fitted 660x440 porcs to the underside of a window ingo. I've another one to do tomorrow or Monday, I will take pics & post them on here.
They are heavy tiles, almost 7kg & once set they won't budge.
HOPEFULLY..

The adhesive will hold the tiles no problem. As for making the grout lines join then it can be done depending on what tile you choose. I have done in the past with 60 x 30 ceramics, I think they where called travertine (marble effect from tile giant), so I basically made the tiles larger by joining the with near invisible results. Best solution IMO would be to pick a different contrasting tile for the sloping wall and make a feature of it. I think your biggest concern should be the flatness of the sloping ceiling though and how level it is where it joins the main walls. Can be tricky, you don't want to be packing tiles out at all in this situation so prep will be key.

Theres stone cladding stuck upside down much much bigger than 600x300 on buildings everywhere.

Ive stuck 3 mt Lengths of cornice on skimmed ceilings/walls which take 3 of us to hold up , stuck and still stuck.
If its done right it holds

and if it fails it is on you

 

[widler]

and if it fails it is on you

Ha ha ha yes deano,stating the obvious , but if its done right why should it fail ?
Jesus, how many bloody window heads have we all tiled, or do all you' its gonna kill you' folk just paint them?
Anyhow it,im not bothered , do as you wish thread starter.
Im off,things to do and people to kill with my workmanship ��

You can make the grout joints meet dependant on which way you fix the tiles and whether a tile larger than 60x30 is available.

If you fix landscape so the 30cm (side A) is vertical and the slope of the roof is 45 degrees, then the adjacent length will also be 30cm (side B).

Therefore, you multiply 30 x 30 (side A) answer is 900. The same for side B.

900 + 900 =1800

The square root of 1800 = 42.42

Then the minimum size of tile required would be 60x43. If they do a 60x45 then you will be able to match the joints on the sloping wall. Alternatively, 60x60 would also suffice.

Simples.

It's all down to the prep though. If you don't get that right and fix tiles to the slope then please provide customer a list of helmet sizes available and where to purchase :helmet:

I can tile but maths?? anything more than 2x2 :sofahide:
