Drew1000 Posted May 3, 2020 Share Posted May 3, 2020 looking for some advice on how to finish the plasterboard at the junction between ceiling and sloping wall in attic room. I have put two full sheets of plasterboard on the sloping part of the ceiling. Another sheet has been fixed to the ceiling. The issue is I am only left with about 35mm of a gap at the junction. Do I just cut a thing strip of plasterboard and piece it in and let the tape and finishing take care of it. I have battened it all out so I have a fixing for screwing the small strip to. I am keen to give the tape and finisher a good straight join to work with. I have attached a drawing which hopefully shoes the problem. Link to comment Share on other sites More sharing options...
ProDave Posted May 3, 2020 Share Posted May 3, 2020 I take it you have fitted a 1200mm wide board on it's side and the length of the sloping part is 1235mm hence the gap? If so i would have put the boards vertical and cut to the exact length. 1 Link to comment Share on other sites More sharing options...

I would - don't see a problem with it so long as you have good fixing. Link to comment Share on other sites More sharing options...

But a note to anyone else doing this, put the boards upright and cut to length so no infill bit needed. Link to comment Share on other sites More sharing options...

Not sure I could justify that for something that should never show. Link to comment Share on other sites More sharing options...

No, because almost certainly the slightly less than half a board offcut would be just right to do the vertical bit of wall up to the sloping ceiling. I was surprised just how little waste there was when I boarded my house. My philosophy was every offcut was stood up or laid down so you could clearly see it, and I was constantly looking for places where an offcut would work nicely and get used up. All I ended up with as waste really was little slivers of board where such offcuts were trimmed a little more to make them fit their destination. In many cases if I needed an offcut to finish a run and I didn not have one, I would not cut it from a fresh board, but leave it out, and wait until a suitable piece became available.

Drew1000 Posted May 4, 2020 Author Share Posted May 4, 2020 I take it that would mean having a tapered edge with square edges along the 10 meter length of room. I take it this is not an issue for taping and finishing ? Link to comment Share on other sites More sharing options...
