'No More Ply'

[FreeD]

sand and cement needs 2 weeks to dry. You can then tile straignt onto it...make sure u get a smooth floated finish. Once dry sand and cement will hold all tiles...no need for tanking either.

No reason why u can't do it yourself if worried fix level battens to the wall at about 600 centres...render inbetween battens...once going off remove battens and fill.

PVA walls first couple of coats 50/50. water/PVA then 6:1 sand/cement + plasticiser.

Hi mate, you can put a rapped set render on you can tile 24 hours after its been up. It should not cost you much to get some one in to do it, just make shore their happy with rappid set.

Thanks guys.

I may give the sand and cement rendering a go ! wish me luck.

Am I right in saying it should be 6 parts sand to 1 part cement?

What sort of sand should I use?

Regards

Chris

4-1 would be your best bet, a fine sharp sand, B&Q do a plastering sand at their bigger depots

sorry mate, dont know, what i do know is it will be cheaper to get some one from the start than to repair a mistake, but you sand like your prity handy. its up to you mate, just dont render a wall so bad you cant till it.

all the best.

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.
