Hi,
I am just about to start fixing 50mm thick kingspan insulated plasterboard to my gable end wall. I have spoken to Kingspan and they have recomended an adhesive.
However I do have one question the internal walls are all painted if I prepare them with PVA I have read that you should score the wall first with a stanley knife to give the adhesive something to grip too. Should I score the wall first then PVA or PVA then score
Thanks
