Alexphd1 Posted March 17, 2018 Share Posted March 17, 2018 Quick question, what comes 1st? Board the wall then fit the staircase, or fit the staircase then board to the top of the riser? Straight stair case with full height wall either side. Oak string & mdf riser/treat. Link to comment Share on other sites More sharing options...
richi Posted March 17, 2018 Share Posted March 17, 2018 Surely you want your plasterwork done first? Or am I misunderstanding the question? Link to comment Share on other sites More sharing options...
Dee J Posted March 17, 2018 Share Posted March 17, 2018 Full height wall both sides of the stairs? Prefabricated staircase or in situ build? Cant see that you'd manage to slot a prefabricated staircase between two plasterboard walls without damage.... Link to comment Share on other sites More sharing options...
Alexphd1 Posted March 17, 2018 Author Share Posted March 17, 2018 Prefab. Would have have to dropped from above which is pretty easy but prob damage plaster board somewhere. Would be nice to get stair in and board/tape later. Link to comment Share on other sites More sharing options...
PeterW Posted March 17, 2018 Share Posted March 17, 2018 32mm strings ..?? fit it first and board after - that’s our plan as the plasterer recons he can get a better finish and we won’t have any gaps as most modern staircases are CNC made so very accurate and walls are not ...

Alexphd1 Posted March 17, 2018 Author Share Posted March 17, 2018 Yes 32mm string. That would make life v easy, which was the original plan. But a friend/joiner mentioned most likely to crack between the string and plaster. Link to comment Share on other sites More sharing options...
RichS Posted March 17, 2018 Share Posted March 17, 2018 Small quadrant or scotia mold between wall and string will cover any cracking. Link to comment Share on other sites More sharing options...
Oz07 Posted March 17, 2018 Share Posted March 17, 2018 (edited) Can never seem to stop this cracking with drylining. I find moulding makes it worse by putting cracking into 2 edges. I think next time if drylining I would screw 12mm ply to wall but wider than string and along same line. Then screw string to this but packed off with 12mm offcuts and more if nessecary. Then drop board behind string when drylining and screw through above the string into ply\osb. I think the inevitable crack would be much smaller this way as timber will shrink across 9" much more than it would over 32mm Edited March 17, 2018 by Oz07 Link to comment Share on other sites More sharing options...
Oz07 Posted March 17, 2018 Share Posted March 17, 2018 If accurate timber frame I'd board and skim beforehand. Especially between 2 walls and straight flight. Link to comment Share on other sites More sharing options...
