Which way do you lay plasterboard?
Which way up should I install plasterboards? When installing a single layer of Gyproc plasterboard, it’s best to hang boards vertically.

Do walls sit on subfloor?
A subfloor is the solid base underneath the floor covering that you depend on for the stability of both the floor and walls in a room. Though it’s not the main support system—that’s the work of beams, posts, and joists—it does its fair share of the work.
Can you just paint plasterboard?
Painting or wallpapering over a plasterboard wall is pretty straightforward as long as all the joints and fixing holes are filled correctly so they don’t show through your chosen wall covering and that you also seal the surface correctly to ensure a good bond.

I always hang the top first because you can get a nice tight joint with the ceiling, and ensure that the sheet is square to the ceiling without having to scribe it in. Then I hang the lower sheet (or sheet plus some) tight to the upper one. Any gap at the floor will be concealed by the base boards.

Should you leave gap between plasterboard?
Also when there is no gap when boards are too tightly against each other cracking will occur. 3-5mm is good.
Should you stagger drywall joints on walls?
Generally, yes, sheetrock should be staggered. Most drywall contractors recommend staggering sheetrock boards so that the joints in one row do not match up with the joints in the next row, which adds strength to the wall or ceiling and helps minimize cracks.
What side do you plaster on plasterboard?
The dark side goes inside so that you skim the outside, which is the white side. If the wall you are boarding is an outside wall, you still put the dark side inside, that is, against the inside of the outside wall.
