Hi. Can anyone help? I have been a complete numpty this weekend and plasterboarded a ceiling with the wrong side facing down for skimmimg!!!! It's Gypsum plasterboard and it plainly says on the side that I have showing "plaster other side only".
The last time I plasterboarded was years ago and I'm sure the plasterers always asked for grey side to skim on???
Could I pva it (or something) and then get it skimmed?
Any help would be much appreciated.
