I have recently got qoutes for replastering my bathroom cowling after pulling down the polystyrene ceiling tiles.
This has left the plasterboard behind it very uneven due tothe patches of glue, as they had spread it over everything instead of dabbing the corners, and the small patches where the plasterboard has torn.
One plasterer advised they would use bonding to smooth it over, then skim over it.
A second plasterer advised they would use a totally different method as the bonding would not be suitable to use in there due to the moisture in the bathroom and lack of a waterproof layer to protect it from the steam.
Which is correct? Is bonding a suitable material to use in this scenario?
Are you a tradesperson and able to answer this question?
Their are different ways to do the job neither is wrong, I’d however opt to bond it with a tight coat then skim with multi finish, neither job with be protected against the water/stream until it’s been sealed and completed with bathroom paint which repels the water, as stated above if their is a issue install a extractor unit.
Hope this helps
I would be recommending new plasterboards fitted over the existing ceiling. This giving you a brand new ceiling before a skim coat. If there’s an issue with steam build up then I’d certainly consider bathroom paint to finish and also an extractor fan.
No issue with using a tight coat of bonding to smooth out the ceiling surface prior to skimming it. As long as ceiling surface is sound and secure. The sealing of the plaster will be completed once the ceiling is decorated with the appropriate bathroom/kitchen paint suitable for areas where it’s prone to more moisture than usual.
Using bonding as a base on a bathroom ceiling isn't wrong if the moisture extraction is good and the current ceiling provides an adequate key. I haven't seen the state of the current ceiling but just for peace of mind and if the budget allows for it I would look to Rip out and re board or batton and re board.

the second plasterer is correct as bonding holds moisture not suitable for bathrooms or any outside walls.
