Plastering over a previously water damaged wall - need advice

[Adam100883]

Hoping for a little advice if possible.

Our boiler sprung a leak and water trickled down through the floor and damaged our bathroom wall. Thought i had dealt with the damp and waited months before stripping the paint and replastering. However when i did replaster parts look wavy. Uping touching this it felt like wet paper. The plaster has now dried and has cracks in it. Please see image attached. Is this something i can plaster over or do i need to cut this section of dry wall out and replace?

Any help would be seriosly appreciated.

Thanks

Has it been re skimmed? Possibly had the plaster laid on too thick in this area or some bare brick/mortar/backing plaster not been sealed properly before skimming and it's sucked the moisture out and dried that area too fast

It will need knocking off the substrate sealing properly then re plastering

I suspect you still have a leak.

I just plaster over stains and see what comes through. I then stain block and paint..Possibly a leak that's now stopped although it's summer and heating isn't on. Sometimes you only get a leak when heating is on. It's strange though.. Investigate more I would..
