Is Bonding Plaster Suitable for a Shower Room on the External Wall?
Anonymous user 28/02/2024 - 3.06 PM
Hi there, I have read on a similar forum that standard practice is NOT to use bonding plaster in rooms where moisture levels are likely to be high/er (such as wet rooms and/or shower rooms); I also read that bonding plaster should not be on ground floor external walls (i.e. on the inside of an external wall). Please can someone confirm if this is the case? I do have more context to add, if necessary, but hopefully that is enough to go on for now. Thanks! Gavin

100% No. You shouldn't even tile on bonding without a skim finish and primer. Your best choice is sand and cement render. Failing that, Line the walls with Hardiebacker board or aqua panel plus a tanking membrane a least 1 metre high with tape jointing the walls with the floor.

You can dryline the shower walls using Aquaboard and wet plaster over that.
Or depending on the substrate, the plasterer will use either Gyproc Hardwall or Gyproc Bonding. Providing the area is fully tiled, any one of these methods will be okay.
