I have a job coming up which I am currently specing out. It is a large (20m2) wetroom that requires UFH. Floors are traditional floorboards which are to be overboarded. Shower former is most likely going to be Marmox showerlay.
Question I have is how is the best way to carry the UFH onto the former. I want to SLC the UFH matting but I am unsure how best to do this? Until now I have always either not fitted UFH in a wetroom, or stopped it prior to the gradient of the former commencing.
Any ideas or photos would be great......cheers
Sorry if similar has been asked before

It might be wise to stop the UFH short of the tray.. the heat will transfer to the tray tiles...

Stick 2x1 to the tray with silicone to prevent slc flowing away and then when set peel the timber away and feather the tray with adhesive..

Just to add that PHG wetrooms have an offer this month..

Cheers Dave. This is exactly what I have always done to date, but client would prefer UFH over the former too

Tell them it is unwise as if a tray failure occurs then they lose the ufh as well.

recomend waterproofing over ufh and as Dave says stop ufh at tray
