There are varying methods used when repairing holes in plasterboard, depending on the size of hole will determine the method used. Small to medium sized holes not in excess of 12 cm in diameter can be easily fixed using a plasterboard wall patch. This is the simplest method which utilises a thin metal mesh patch with an adhesive backing.
I have used this method many times when fixing holes in plasterboard. It’s simple, fast and inexpensive, the technique I use differs slightly from the manufacturer’s instructions, here’s why.
Patches covering holes in plasterboard sit on the outer surface, they are not flush. The user must use a technique called feathering when filling and sanding in an attempt to blend the patch into the surrounding area.
Unfortunately what tends to happen is, oversanding exposing the patch, or not sanding enough, leaving a visible bump. For this reason I have adapted the process to avoid feathering the filler.

Repairing Damaged Plasterboard
1) Using a pencil mark a square around the hole. Leave a gap of 10mm from your pencil line to the edge of the hole.
2) Take your stanley knife and score the square line cutting through the plastered surface into the plasterboard.
3) Use your stanley knife to remove the thin layer of plaster from the edge of the hole outwards to the square. This will leave the square 2-3mm shy of the surface.
4) Take your Plasterboard Wall Patch and first remove the self adhesive backing with your scissors, then Measure and cut a piece of the metal mesh to the same dimensions as the square.
5) Using your CT1 Adhesive squeeze a bead around the hole and then place the metal patch over the hole. Press firmly until the adhesive squeezes through the mesh. The patch should sit flush with the surrounding surface.
How To Fix A Hole In The Wall Fast
The above method is by far the fastest way of repairing a hole in plasterboard, (10 mins). Waiting for the filler to dry is the most time consuming part of the project. Plasterboard patches are readily available, cheap and easy to use. No waste and No travelling to your local builders merchant for materials.
At times you may find that some plasterboard walls haven’t been skimmed. Instead the joints have been taped, sanded and the walls painted.
This technique is becoming more common in new builds, as its cheap and fast. How then do you fix a hole in plasterboard when the wall hasn’t been skimmed.
Simple, use the exact same method above. Plasterboard sheets are made up of layers and layers of paper glued on top of one another. Instead of cutting through the 2-3 mm of plaster then removing the waste so the patch sits flush with the outer surface.
Use the same technique, only this time cut through the paper layers, remove the excess. Check the patch sits flush, then glue in place. Skim, sand and paint, repairing holes in plasterboard is simple using this modified technique.
