My loo has been flooded 3 times in 8 months by my upstairs tenement tenant neighbours. So I have given up sticking the wallpaper back on and have stripped it all off only to find uneven rubbish plaster underneath. I knocked away loose plaster, covered all the walls with pva solution, bought some wickes multi-finish plaster, mixed it as instructed and applied it to the walls over several plastering sessions. However the finish is not good - at best the plaster is flat but a bit gritty to touch and at worst it has little 'puddle' holes/ uneven parts. I was told to let the plaster get almost dry and then go over it again with a wet trowel. Might give up and call in a pro but thought I might just see if anyone can enlighten me on plastering technique and best finish plaster to use??
Thank you kindly for any helpful suggestions,
