A Bit Of Advice Needed

Hi, doing a bathroom floor soon with porcelain tiles and under floor heating, about 5 square meters. The house is quite new and has chipboard flooring.
Normaly i would overlay the floor with 12 mm ply, lay the UFH, self leveling compound, and a fleix adhesive. The customer wants to keep the floor level down so, i was going to make sure the chipboard is screwed dowd solid, lay the UFH, use a flexi leveling compound over the mat,as i use Granfix products, then use Granfix ultimate flex and grout. Firstly will this be ok and second if it is what would be the best levelig compound. Cheers Mick.

Mick......i'm not a big lover of tiling direct to chipboard.....

If you make sure it is solid then overlay with 6mm hardi backer then lay ufh and level over with mapei fibre plan.....nice strong floor then and no great height increase...

I've ordered some plastic ply from nicobond today, going to try it on a 4m2 bathroom floor to overlay t&g chipboard next week, after a lenghy discussion with the area rep i've been assured that it's suitable, ill let you know how it goes.

Use a product called No More Ply only 6 mm thick then use single part flex adhesive

No more ply is different mate, no more ply is a tile backer board, where as plastic ply is a plastic sheeting type thing, hard to explain but plastic ply is sold at nichols and smith tilestyle at leeds. There arent any other places in W.Yorks that sell it to my knowledge at the moment, maybe thats not such a good sign

Just glue n screw 6mm ply but prime both sides and edges, easy.

Not Really keen on using 6mm ply but over this small area might be ok hardibacker seems best option. Cheers
