Will by bathroom end up in the flat below?

[sutton1977]

Hi, Just extended my bathroom and my 400x600 porcelain tiles arrived today:rolleyes5:

Ive tiled a bathroom before, but never with porcelain. Hope the walls can take it!

It is a Victorian house with thick (20mm) plaster directly onto the brick on one side, and the new stud partition on the other with 12mm new plasterboard, unskimmed.

I've seen on the other forums that I need flexible adhesive but do the walls sound okay?

Thanks

:welcome:sutton1977 - only you can tell how solid the plaster is to the brickwork to assess the strength of the plaster, but for the unskimmed plasterboard you'll have to check the weight of the tiles + adhesives as the guideline is 32kg/sq metre.

Have fun.

you'll have probs with the skimmed areas imo, safe load limits for skimmed plaster are 20kg m2, you also have to factor in adhesive and grout with this weight, typically 4kg m2.

Hello and welcome

welcome

Thanks for the advice. So, should I put up some other sort of board, rather than plaster board? (now it's all been delivered!):mad2:

If I secured marine ply to the studs and noggins, would that be better?

Tiles are 26kg m2!

i would go with cement boards, hardie backer, or similar

 

[doug boardley]

as above^^^ for me

As above, don't use ply on the walls. I would use backer boards mechanically fixed to the wall.

Excellent,

Thanks, off to Wickes now! After 10 years of living with a hideous aquamarine bathroom with blue tiles, I think it's finally going to get done!:hurray:

Hi and welcome

The plaster sounds like lime mortor which would'nt take the wieght of the tiles

Thank you all for the advice, I'll be buying the aqua-board on the weekend and you'll be able to see how it looks on DIY SOS later in the year!:smilewinkgrin:

Welcome along to the forum

Well, after discovering that I have run out of funds until I get paid next week, the project is on hold...:mad2:
A question about weights:
My walls are plasterboard. The tiles are 600 x 300mm porcelain and are 10mm thick. The box is 25kg for 1.08m2.
That makes the tiles 23kg per m2 in my mind. (25/1.08=23). Even if I add 5kg for adhesive, it's still under 32kg, so I can tile straight onto it?
Does that sound right? Can't really afford (or fit in my car) the Hardiboard:yikes: and its only a small wall (1.5m by 2.7m)

Also, whilst I'm asking, what Mapei adhesive should I use for these porcelain tiles, they will be on the wall above and the whole floor?

Thanks!:smilewinkgrin:
