How to Fix a Plasterboard Hole

Updated February 21, 2017

Fixing a hole in your plasterboard wall is a relatively easy job to do. Just about every home will get a hole in the plasterboard from one thing or another. The most common hole in plasterboard is a hole from a door handle. The easiest method to repair a hole 6-inches or smaller would be to use a adhesive mesh and metal drywall patch. Self-adhesive mesh and metal drywall patches are available in 4-inch, 6-inch and 8-inch sizes.

Measure the hole at the widest point to determine the size of the self-adhesive mesh and metal drywall patch needed to cover the hole. Use a patch that is 2 inches bigger than the hole. For example, if the hole is 4 inches at the widest point you would use a 6-inch patch.

Remove any plasterboard sticking out of the hole. Slide the 4-inch putty knife across the hole to remove any debris around the hole.

Peel the backing off the self-adhesive patch. Center the patch over the hole. Press a corner of the patch onto the wall and slowly apply the patch, using your putty knife to smooth the patch over the hole.

Scoop a putty knife full of joint compound onto the trowel. Apply the joint compound on to one edge of the trowel. Press the edge of the trowel against the wall, 2-inches away from the patch and slowly apply a thin coat of the joint compound, with a sliding motion across the hole.

Scrape the edges with the putty knife to smooth the edges. Allow to completely dry, then apply a second coast of joint compound.

Sand the joint compound smooth, using a sanding block when the joint compound is completely dry.

Paint the joint compound with a drywall primer, then paint the patch the same colour as the wall.


To prevent the door knob going through the plasterboard, a door stopper should be installed on the baseboard behind the door.
