Tiling onto new build chipboard subfloors.

[Rich Midge]

Hi all, just wondered what methods people prefer? We are due to start a new build house next week with approximately 150 metres 60 x 60 porcelain to lay. The chipboard subfloor is well screwed down though I don't know yet if if extra noggins were put in. There isn't enough room to overlay with 15mm ply so we're looking at some kind of anti fracture membrane or tiling direct to wood. We're currently having issues with Norcros permalayer and have lost confidence with it in this kind of situation. I like Durabase, but the client doesn't want expansion strips. Any other suggestions would be greatly appreciated!

As above

 

[Rich Midge]

Will hardie guarantee this method? No More Ply maybe as another possibility?

 

[cam_low]

As above above.

6mm insulation boards if he floor is deflection free for me.

 

[Mr Tiler]

Really? where ?

 

[Mr Tiler]

I have seen a couple of posts over the last few months and many people were nocking it. so I came to the conclusion to never use it to cover my back. obviously I was wrong lol... I remember specifically a post from I think bri saying it has a thin laminate layer so isn't trust-able

I have been using it the best part of 10 years without any issue !

I think I said I didn't like it because it was shiney, just a personal preference thing really. I just prefer hardie.

 

[White Room]

Half the time it's whats available in your area....

 

[John Benton]

I have choice of both, used to use NMP but changed to Hardie. I found that NMP was more brittle and could snap when screws are close to edge, also screws didn't always countersink in and stood proud, whereas Hardie the screws go in reasonably easy.

 

[widler]

I have a info leaflet on it, it says its ideal fo wet rooms as its fully waterproof as long as you silicone each joint(with there glue as thats 100% waterproof)

 

[Mr Tiler]

sorry that was inexperience talking lol yeh ok well I may have to work with this stuff and get my own feel for it soon cheers

There you go Ash - have a read of this

Cement Boards, Tile Backer Boards | No More Ply

 

[Rich Midge]

Really appreciate all the replies thanks! I just need a product which guarantees a perfectly stable, crack free floor 10 yrs from now. I have no problem guarantying the quality of my work, just want the same back up from the products I use. We had a problem about 8 yrs or so back with NMP. The tile and adhesive had completely de bonded, coming clean off the boards. This was a commercial kitchen with a central drain. The client prepped the floor himself, I'm convinced he used a cheap layer forming primer which caused the problem. However, it did knock my confidence in it. So I'm thinking now Marmox boards maybe or Hardie. Have to admit, I've not used Hardie much.

 

[Kevboy]

Hardi is the dogs b.... IMO

 

[Rich Midge]

Decision has been taken out of my hands. Porcelanosa are sending someone out to spec the job, so they'll be guarantying the floor. Anyone any opinions on Porcelanosa own brand adhesive and grouts?

 

[martin1c]

Porcelanosa sell Butech adhesives which is made under licence by Mapei so it's good. The grouts are ok but they do tend to go off quicker than Mapei grouts for some reason.

One Flex is a good quality adhesive.
Don't like their grout though, ok on a floor but a bugger to work with on walls.
