Hi. I need to do a small amount of repair work to skimmed plasterboard (not skimmed by me!). It seems like the previous skim has not adhered to the plasterboard really at all and comes off in large pieces. Is there anything I should do to help it adhere this time? Or just skim over the board again? The skim is over the grey side of the plasterboard, if that matters. It was done about 5 years ago.
Thanks,
