Bit of advice for new arrival....

**BogBeast** · 12-09-2011

Hello all.

I have a couple of bathrooms and a floor behind me and so far I seem to be doing alright (better half is impressed)

I am about to start the 3rd bathroom and this looks like it going to be more of a challenge.

I have bought a batch of rather nice marble tiles off of the dreaded eBay and I would like to put them on all the walls, floor to ceiling.

They are 300x300x15 and weigh approx 3.5kg per tile. I have never tiled with this thickness and I wanted to make sure I have done my prep properly..

2 of the walls are block, one new - never had anything on it. The other has had the plaster removed and is a bit bumpy.

The other 2 walls are stud from which I have stripped the crappy old plasterboard...

For the stud - would 12.5mm Aquapanel be suitable? or are there better boards to use (considering the weight) - Wickes is local to me....

For the block walls - I was going to skim the bumpy wall with a strong cement render to give a good surface and then tile straight onto the wall. Or would it be better to board the block wall too?

I was planning on tanking the wet corner with MAPELASTIC AQUADEFENSE and leaning towards a 3mm bed of PCI Nanolight (should I be able to find it locally).

Any advice gratefully received ....

Many thanks for the replies,

Their datasheet states that the boards will hold 62kg/m. Is that the 6mm as well ? (I am restricted on depth on one wall and would like to put the 6mm boards up)

For the block wall, would you use their plugs or would their washers, a screw and plug do?

I am going for a thin solid bed trowel, probably on all the walls. Would that be overkill?

Many thanks again...
