plasterboard question

[johnryan]

hello all, just a quick question about tiling to plasterboard. it a first floor room with a dorma window so one of the walls to be tiled is at a 45 degree angle between the wall and ceiling. i'm sure you know what i mean, cant think of a better way to explain. anyway, the tiles are 600 x 400 porcelaine which are ok for the vertical walls, but not sure if i need to overboard the sloping roof bit with wedi/marmox etc. any clarification on this would be greatly appreciated. haven't been asked to tile this part of a loft type bathroom before. cheers.

Weigh the tile and add 4kg/m2 for adhesive. 32kg/m2 total for weight limit.

How are you finishing the top of the tiles ?

 

[johnryan]

it's ok, i know the weight limits, and tile and addy comes in at 31 kg so fine for the vertical walls i just need to know if they can go on the underside of the ceiling wall where it's at 45 degrees between the wall and ceiling. not sure about the weight limit when the plasterboard is almost upside down if you know what i mean. just put this picture in and have drawn red lines around the part i mean.

Gotcha, excuse my ignorance!

Whyaye man solid bed you will be fine, how will you be supporting them ? Im in the msrket for some decent tile supports rather than the usual batons.

ok, cheers,was thinking it would be fine it would be fine. just wanted to ask here first, as some may have done this before. wasn't sure if the weight limits were the same in this situation. as for supports, im thinking making up a few dead men that tackers use to hold boards up to the ceiling to prop them up till they set. will use rapid set so wont need to keep them there for long, especially as it's so hot.

Yes it is fella, clocked 25 i think today! I may put a few noggins into to strenghten however if i knew i was tiling that i would prefer to use hbb, beltnbraces etc

ok think i may go with hardi then, shouldn't think it'll need noggins, it's only 400mm wide where it need to be tiled like this. that pic i put up isn't where im tiling just used that as an example of the wall to be tiled. anyway thanks for the help. cheers.
