Floor Leveling

[SIMOS]

Good evening everyone,
I am due to start my mums kitchen floor next week. It is only 9 square mts, so not a big job, but I have discovered the floor slopes across the full width by 30mm. My mum has already bought the tile, they are 450x450mm ceramics. I am over boarding the floor with no more ply at 6mm. I was wondering what you all this is the bests way of leveling it up. I was thinking of using some Knauf Aquapanel at 12.5mm thick and glueing and screwing one on top of the other to give me 25mm and feathering into the rest of the 6mm NMP. Is it OK to put one on top of the other or would you simply build up with a leveling compond?

Hope this makes sense.

Cheers,
Sim

leveling compound all day long for me. If you start adding layers of this that and the other your only adding materials that might warp in time.

yeh good point, I was just thinking of all the Leveling compound I would get through. I think I will just go for the 6mm No More Ply then leveel up using something like the Granfis thick bed leveing compound!!

Cheers,

Hi Sim, floors don't always have to be level, just flat.

 

[SIMOS]

Are you with the same opinion Whitebeam adding layers of board may lead to problems in the future?

 

[White Room]

Would'nt go with layering with boards

 

[SIMOS]

You're right faithhealer, I have said to my mum it might not be spot on level, but it will be flat when I've finished. The floor was actually 50mm out but the kitchen fitter has set the units higher up at the low end to balance it out a bit.

Bizzare, its a new-ish house as well!!

Levelling compound sounds the order of the day. Probably wont take as long either.

NHBC guidelines used to say that 25mm fall over 5 linear meters can be acceptable on domestic house floors. I guess NHBC never played marbles....

What's the substrate? Just curious...
