Bathroom underfloor heating -advice

[puntoadzs]

Hello guys, I am after a bit of advice /guidance. I am replacing my bathroom floor with electric under floor heating and a tiled finish. The current floor is floors boards, thin ply and vinyl. The vinyl will be coming up and I have bought insulations boards to be fixed prior to the ufh going down. My questions is in regards to the tile adhesive - is it best to use a flexible adhesive for both fixing the insulations boards and laying the tiles. Ie... Can it be the same adhesive for both and what are the recommended products for this type of work?


Thanks in advance for any advice

Hi, remove the ply as well ..

10mm min insulation boards and yes flexible adhesive for both ... the substrate needs to be virtually bounce free .. then when you have the ufh installed and checked then encapsulate in fibre enhanced SLC..

Weber products are good and what i use at present.

Thanks for the quick response David.

You mention removing the Ply as well... The current floor construction is T&G floorboards with a layer of ply. If i remove the ply can i lay the insulation boards with adhesive straight onto to the floorboards?
