Tiling onto floorboards

[Adrian mcc]

hi all just seeking abit of advice on tiling onto floorboards. I’m tiling my dining room with 600x600 polished porcelain with pro warm underfloor heating can someone advise. Is this the right way I was planning on sticking the insulation boards down with a rapid set from tile master straight onto primed floor boards fixing with washes as well then underfloor then self levelling is this correct or do I need to ply on top of the floorboards cheers

So long as the boards are secure and deflection free then yes that is fine. Dont forget to tape join the boards after laying & fixing
