How to patch a hole in drywall 2 best methods reviewed
Repairing a hole in a drywall or plasterboard is a common task faced by home owners. In this video tutorial I show my 2 best methods on how to patch a hole in drywall. The first method covers how to patch small drywall holes and the second method is how I would repair larger holes in dry wall. Both methods involve removing any damaged drywall so that the repair takes place on sound or healthy drywall. Drywall in Australia is commonly referred by a popular brand name’ Gyprock”. After the initial repair it will be necessary to cover the repair with a suitable top coat filler of ‘mud’. When dry sanding and painting finishes the job. If done carefully the patch should be undetectable.
Up to 6-8mm just use filler
Holes above 15 mm to about 60mm
Drill out damaged drywall with a hole saw.
With same hole saw cut out a core of drywall from a piece of scrap.
Stick masking tape to the outer surface of the core with tails of masking tape at leas 10cm long.
Coat the cut edge of the core liberally with PVA wood glue
Position drywall core in the prepared cavity in the drywall and secure with masking tape.
Remove tape after 24 hours and fill
Sand and paint when filler is dry.
Alternatively do as above but instead of cutting the core out of the scrap only cut through the inner paper and gypsum with the hole saw and preserve the outer paper.
Now score lines in the inner paper with a box cutter from the central core to each corner of the block.
Now fracture drywall along the scored lines and peel the inner layer of paper and gypsum off the outer paper.
Trim paper flanges with a pair of scissors if necessary and liberally coat the fitting surfaces with PVA wood glue.
Position core in prepared cavity in the wall and secure paper flanges to the drywall with masking tape.
After 24 hours remove tape, fill and then sand and paint when the filler is dry.
From a scrap of drywall cut out a square or rectangle large enough to cover the hole in the drywall and extend into healthy drywall.
Position the piece over the hole and mark its orientation on the piece and the wall.
Draw the outline of the block on the wall and cut along that line and remove damaged drywall. Trim the block to fit snugly into the prepared cavity in the wall.
Cut a piece of scrap timber in a rectangle slightly smaller in dimension than the cavity and about 60mm longer in the other dimension.
Drill a stout fastener into the centre of the wooden block and using the fastener as a handle position the block inside the cavity and secure with drywall screws.
Reposition the drywall block and screw to wooden block.
Trim any frayed edges.
Fill, sand paint
Larger holes may require more than 1 timber block to support the drywall insert.
