Do you have a crack or hole in your plaster wall that needs repairing? Is it something that you can fix yourself, or do you need to call a professional. By reading through these instructions on how to make a repair, you can decide for yourself if you need to call in some help.

Size Matters

The method of repairing holes in a plaster walls are different depending on the size of the hole or crack to be filled. But the good news is that by using modern fillers and materials, the repair can be fairly easy to achieve. These days most filler compounds are ready mixed and available in various sizes and colours to suit just about any job.

Small Repairs

For a small crack or hole in your wall, your first step is to get rid of any loose plaster using a sharp knife, then prepare the area by vacuuming or wiping with a damp sponge to remove any dust. Take the pre-mixed compound or mix your cement following the manufacturers instructions.

Use a filling knife, and apply to create your first layer, clean around the area with the sponge and leave for four hours to dry. After the first coat is dry, apply a second coat, which should be slightly higer than the wall to allow for any shrinkage.

Once dry, sand flush with the wall using sandpaper and the moist sponge. Always wear safety glasses and long sleeved clothes and gloves while plastering.

Large Holes

To repair larger holes you will have to cut the damaged area around the hole, and then create a backing support because of the larger area to be repaired. Remove All Damaged Plasterboard

Using plasterboard that is the same thickness as the original, cut out a piece that is big enough to cover the damage, and then mark its outlign with a pencil. Punch a hole with a screwdriver in each corner of the area that you marked, then use a keyhole saw to cut a diagonal towards each corner.

Be particularly careful of any wiring or plumbing in the area. Break away the plasterboard and remove.

Install Your New Plasterboard

Using a piece of timber, screw it in place behind the hole countersinking the screws, and this will be the support for your new plasterboard.

Remove any dust, then apply adhesive to the supporting timber. Fit your new plasterboard into the hole, then tape the edges, but be sure not to overlap the tape.

Apply a layer of compound using a filler knife over all of the joints, to cover screw holes and tape. Once dry, sand with a medium grit sandpaper. Then fill again with a second layer, spreading the compound over a wider area to make the patch invisible.

Sand again with fine sandpaper once dry, and then paint. The video below will give you more ideas on what is involved and where to start.
