Hi. I’m going to fit a bifold door like in the picture (although smaller), but not sure the best order of doing things. The frame fits flush with one wall (with an overhang at the top) and will most likely have a return wall on the other side like in the second pic.
From the installation video, it is being installed over finished plasterboard but don’t know if that’s the best way.
Can you advise on what the best order of doing things is from below…
1. Plasterboard
2. Finish plaster
3. Fit door frame
Many thanks in advance!
