My bathroom is on the second level so the floor consists of wooden floor joists, a chipboard floor then cement board on top and covered in waterproofing. The old screed looked like sandstone (prob sand/cement) and was REALLY stuck down. Do I need a bonded or unbonded screed? Either way the screed can only be 11-12mm thick. The general consensus I have heard is bonded for concrete ground floor slab and unbonded for upstairs. Does anyone have experience with this? What would the best screed mix be for this purpose? Any needed additives? Re: Shower screed confusion 3Sep 01, 2021 11:29 pm Ok thanks, I thought so as well because it is so thin. The old screed was extremely hard to remove so was probably bonded.
