Can MDF be tiled over?

Hi.

I have 18mm green sheets of 8 x 4 MDF on my floor, can this be tiled over?

Cheers

Not in my world. Recipe for disaster imo

I would overboard it with cement boards first..

 

[peterjohnston]

Thanks, I'd do that but the mdf runs into a wet floor tray which has been taped & tanked. I'm thinking that I may need to overboard with 4mm ply up to the tray?

No ! Overlay with hardie board or no more ply

Thanks, but what's the problem with using 4mm ply on top of the 18mm stuff I already have? No more ply will be too thick I think (8mm or so I believe)

You can get 6mm cement boards...........think you can get 4mm marmox boards too...

Of course you can tile over MDF. I know loads of folks who have tiled their shower walls which were MDF.... Usually at least twice

These are Caber Deck boards you are referring to,
As stated over board with 6mm Hardie backer board as long as the floor is solid & deflection free.
