Porcelain floor

[robbieraven]

Guys,

Layer order please. Got 22mm chipboard down on a bathroom floor, Niro Granite Porcelain tiles going down with underfloor heating mat. So my order is looking like this 12mm or 9mm ply screwed at 300mm centres first, then the heating mat, then SLC, then tile?

Anything wrong with that or something I've missed?

Cheers Rob

Exchange the ply for cement boards glued and screwed and you will have a good prepped substrate
