yep 6 sand 1 cement...you may want to go a bit stronger as Whitebeam says...just make sure you do the same ratio for every mix. I believe there is a render available which is fast setting and can be tiled on within 2 hours BAL Adhesives - Products - quickset render not sure of cost...do weber do one of these fast setting renders couldn't see one on there site?

take ure time with the rendering do it in sections and get them level as you go...end of the day does'nt matter if its patchy its all going to be covered with tiles!

Hi guys,

Just to make sure your all upto speed Hardiebacker 500 will take 45kg of tile per m2.

No More Ply is circa 25kgm2. Same as skimmed plasterboard. Backer is likely enough to hold your large tiles but always check 1st.

When fixing backer 250 or 500 to render wall ensure a full coverage on the board with adhesive to fix to the wall and make sure you mechanically fixed as well.

Hope this helps boys,

Andy

I was in the same situation on a job before xmas with 1 tonne of Porcelanosa tiles. We did many tests and in the end opted to go with a good sand/cement render. Yes it took weeks to dry but it was worth it considering the weight!!!

I personally would go down the sand + cement route and have the walls trued up by a good plasterer who is able to apply the render plumb. It will help in the long run when installing the marble.

The sand + cement render will however rubbing the loose sand off lightly 1st then need 2 coats of a polymer stabilizer to bond the render surface together ready for tiling. That will just take a few hours to dry .

IMO I would forget NMP or Backerboard and go the pro plastered render route.

What size are the marble tiles you are thinking of using? What is the total weight of your bathroom wall tiles?

As for a tile adhesive, I used Butec One Flex adhesive.
