'No More Ply' - TilersForums.com

Hi All,

Just about to start tiling my bathroom with marble tiles. The room needs to be tanked as it going to be a wetroom.

The room has a stud wall which is back to the frame and a solid wall which has been taken back to the brick.

I need to prepare the walls so that they can hold the weight of the marble tiles. I have already purchased a roll of Dura WP membrane to tank the walls once ready.

Having consulted a local tiling shop they have advised that 6mm 'No More Ply' can be applied to both walls and then tanked.

Does anyone have experience with this type of backer board?

Is 6mm strong enough to hold marble tiles?

Is there a particular kind of adhesive I should use?

Would I need to use additional fixings for the solid wall, or will the adhesive be enough?

Any advice on what I should do is appreciated.

Thanks

Chris

I'd personally use Hardie 500 for the wall as it's 12.5mm thick.
6mm for floors is fine so long as the substrate is rock solid.

Go for Hardie 500 for the walls (12.5mm thick)
NMP at 6mm will be fine so long as the substrate is rock solid

as the guys have said, 6mm ok on floor but would normally use 12 mm Hardibacker on walls. Use white flexible adhesive for tiles. Gray may discolour the tiles

Thanks Guys,

One last question: is adhesive alone strong enough to bond the board to a brick wall so that it can hold marble tiles, or do I need to screw it in place?

If I need to screw it in place are standard screws and plugs sufficient and how much spacing is required?

Thanks

Chris

Adhesive should be enough but I usually screw as well (I use drywall screws into studs or plugs if into blockwork.
NMP has it's own screws and polyurathane glue

whats generally better to tile to, plywood or plasterboard? If you had a choice what would you prefer working with

Why not plaster board the one wall and rough the other with sand and cement why you going the expensive route ??

Im not shore but if the tile is as heavy as he is making out he might be above the recomended wight for plaster board?????

also could he not have the brick renderd?

Thanks for your anwsers guys, they're very much appreciated.

I didn't want to use plasterboard on the stud walls as I don't think they hold the weight of the marble tiles together with the membrane and all the tile adhesive.

On the solid wall I would consider rendering it with a sand and cement mix but I've tried anything like this before and don't feel confident that I'll get a straight enough finish. Would it be cheaper to get someone into do this for me? How long would I have to leave it to dry for?

As a result I thought I'd be able to fix a tile backer board without to much trouble and should get a reasonable finish. I know this is probably not the most cost effective way to do the job, but with such limited skills I think its my only option.

Regards

Chris
