JamesP Posted January 21, 2019 Share Posted January 21, 2019 (edited) Advice needed please. Have a 22mm Caberdek on the first floor and plan to have a Wet room bathroom with UFH and a waterproof concrete floor. No UFH under the shower former at the moment. Is it possible to put a 20 -30mm screed on top of Wunda EPS with a Impey waterguard membrane between the two. Any info would be much appreciated.

A screed at that thickness will need to be bonded with a very good primer. If I was doing a Wetroom former ‘hand-crafted’ then I would be using a flexible tile adhesive to bench it all in. ( just so happens that the next en-suite will be receiving a bespoke 900mm x 2700mm Wetroom walk-in shower test made from scratch by yours truly ). Wish me luck. ??
