The two main repair methods can be found below: Repairing a Plasterboard Hole Using a Piece of Plasterboard or Timber

In both cases, you'll need to skim over the undercoat plaster or the plasterboard to achieve a smooth finish, smooth enough to paint onto.The final stage to this repair is to fill the hole with a suitable filler such as Polyfilla or the like. Once mixed (or the tub is open if you have a pre-mixed version), scoop out a lump using a small trowel and apply it to the hole, using the trowel to completely fill the area of the hole by pushing into the corners. Due to the nature of plasterboard and in a similar way hollow doors, they can become damaged quite easily. Most modern ceilings are built from sheets of plasterboard nailed to the joists. These joints are taped with scrim - a very open-weave, self-adhesive tape. Wet plaster is then added, or the ceiling is finished with jointing tape and compound - which seals the joints and creates a surface ready for decorating. The floor of the room above a plasterboard ceiling may well be laid with floorboards or chipboard. Suspended ceilings For both options, once the bonding coat has dried it's time to apply the finishing skim. This can be applied over the bonding coat, the existing plaster and the plasterboard.

Yes you can use decorators' caulk to fill small holes such as nail and screw holes, but it's not really suitable for holes any bigger than quarter of an inch. Add a dollop of caulk and smooth out with a putty knife or a wet finger for nail and screw holes. With mine, I troweled off my bonding coat so that it was flush with the surrounding (good) plaster. This was because I was completely skimming over that wall, so the finished level will be a couple of millimeters above the existing good plaster. As well as using plasterboard to fill a small hole to the corner of my window (as seen in the above picture), I also used plasterboard to one side of a window opening, like so:

Now you will need a piece of plasterboard to fill the hole. Ideally this needs to be thinner than the current plasterboard. Measure and cut to fill the hole. Fix in place against the noggins with plasterboard screws or nails. Once the final layer has dried, you can smooth off any seams or imperfections. As before, use the Hoover attachment if you have one on your sander or alternatively, mask up and catch the falling dust with the Hoover nozzle under the sander/sandpaper. Now draw two lines across the gap to create a rectangle around the hole. Cut out the existing plasterboard with a sharp Stanley knife or use a small jab saw. Once the patch is dry and firmly in position, gently remove the screw. Use patching plaster, all purpose filler or multi-finish plaster — mix up enough to cover the patch and gently press into the hole and spread with a putty knife that is larger than the hole to help get a smooth finish.

If there are only a few bits of detached plaster, great, this means you're in the right place, read on. If there are lots of loose bits of plaster and you're unsure whether it's worth patching it up, I would opt for removing the lot from that wall and re-plastering it all, better safe than sorry. To learn how to completely re-plaster a wall, start here. Wait for the bonding coat to set overnight. When you return the next day, use the wide scraper to gently chip off any protruding bits that'll get in the way when skimming.

Repairing a Plasterboard Hole Using a Piece of Plasterboard or Timber

I have seen and heard a lot of people applying a 1 part PVA and 3 part water to the masonry and allowing it to dry before attaching the plasterboard. Whilst this is not mentioned as part of the plasterboard adhesive instructions, it does seem to be an accepted solution.

This method is very similar to fixing holes in plasterboard on walls. If it’s a small screw hole or nail hole just use a putty knife and a suitable filler, and smooth out. Rub down when finished. If you're not confident with plastering large areas, plasterboard will achieve a flat surface with which to skim over. Another complication that springs to light when you have unfortunately made a hole in a plasterboard wall or hollow door is the void behind it due to the construction of the stud work used to hold the plasterboard up or provide the framework for the door meaning that you can’t just use filler as there is nothing to bond it to.Option 2 - Fill most of the hole with plasterboard, then the gaps with an undercoat plaster, then skim over Cut a piece of plasterboard that is slightly narrower than the hole but an inch or so longer top and bottom. Screw in a long screw in the middle of the patch; this will be used to position the patch in place. To repair a hole in a hollow door, wall, or ceiling, firstly trim the edges of the hole and make is square. Ironically, you actually have to make the hole larger before you can go about fixing it! So I'm guessing it's loose, echos slightly when you tap it, with a little bit of movement. Then, when you remove the wall paper you see something like this:
