I'm fitting out my bathroom and want to replace the wooden panellened ceiling.
Is it ok to put plasterboard up then skim over with some plaster to get a smooth finish to paint on or will this soak up the moisture?
Go to our top coat plastering project and read carefully. Spend a few quid on a piece od plasterboard and a bag of plaster to practice on first. The money this costs will be saved 100 times over if you mess up the ceiling. PLastering is a trade and requires practice, practice and more practice.
