How to fix a hole in plasterboard

Due to the nature of plasterboard, it can become damaged quite easily. Plasterboard is soft and the slightest impact, such as moving furniture around, can mark the surface and even put a hole through it. This can ultimately cause complications, resulting in problems with the framework and stud work.

Fortunately, there are a few tricks you can use to successfully fill a hole of this type. Additionally, if you take your time over the repair and filling stage, then there is no reason why your repair shouldn’t be very hard to spot. And, this technique can also be used to fill holes in hollow doors!

The method is as follows:

Repairing a plasterboard hole

As you will need to do a bit of cutting, first run over the area around the hole with a wire detector to make sure there aren’t any wires, pipes, or other items that you may accidentally cut through.
Then, start squaring the hole up by trimming the edges of the hole to make it square. Ironically, you must make the hole larger before you can go about fixing it!

Depending on the shape of the hole, whether it’s circular or has jagged edges, you may need to use a padsaw, jabsaw, or hobby knife.

1. Cut a repair patch

Now that you have squared up the hole, the next job is to make a patch. You can either use a scrap piece of plasterboard or timber. Hold your chosen patch material up to the base of the hole and mark its width, then, once marked, measure and cut the patch to the correct width and then check that it passes through the hole nicely.
Hold the patch to the side to mark its height but add an inch on top and bottom. This is what you will use to stick the patch to the rear side of your wall. Once marked, cut to the correct size.

2. Push the screw into centre

With the patch ready to go, the final job is to drill a small hole through the centre and push a screw through. The screw will be used to position and hold the patch in place until it dries. Once it’s dried and stuck in the hole, you can push the screw out into the wall void.

3. Add Adhesive

After that, you will need to add some adhesive to the inch overlap that you left on the longest side of the patch and around the sides using any sort of heavy-duty construction adhesive.

4. Insert the patch into the hole

Pick up the patch by holding the screw and tilt it to insert it into the hole. Even it up so that you have a decent amount of overlap at the top and bottom so that the patch will be held firmly in place once the adhesive has set. Use gentle pulling pressure whilst also moving the patch around slightly to ensure good contact between the adhesive and the back of the surface until you are sure the adhesive will hold the piece in place.

Once the adhesive has dried enough to support the patch, you can now push the screw out into the wall void. Leave this for a further 24 hours for the adhesive to completely harden off so then you can start filling.

5. Fill the hole

The final stage to this repair is to fill the hole with a suitable filler, such as Polyfilla. Once mixed, scoop out a lump using a small trowel, and then apply it to the hole. Use the trowel to completely fill the area of the hole by pushing it into the corners.
Add as much filler as you need to until the hole is filled in line with the surface of the wall. Then use the trowel to get the surface as flat as possible.
