MortarThePoint Posted May 8, 2022 Share Posted May 8, 2022 I have two sheets of plasterboard that snapped whilst being carried. They didn't get dropped, but the snap is straight across and the sheet folded to near right angle. I saw in the BG book it says not to use damaged sheets, but how do you feel about this? They are moisture resistant and for bathrooms where they will be over OSB. On one sheet the crack is square to the edge of the sheet so much like how you'd join a sheet. On the other it's at a slight angle so may be no good. If using the one that's square, I could cut it clear and leave a small joint for the plaster skim.

markc Posted May 8, 2022 Share Posted May 8, 2022 Best practice states lots of things you shouldn’t do, but are done regularly. an unsupported crack or fold wouldn’t be good, but over OSB I can’t see any problem unless it’s not getting skimmed. 1 Link to comment Share on other sites More sharing options...
MortarThePoint Posted May 8, 2022 Author Share Posted May 8, 2022 I can understand the concern if the crack isn't supported by material behind, but ultimately if you just treat it like a join surely(?) it can't cause any problems Link to comment Share on other sites More sharing options...
