Garage wall repair is a common job after a car gets a little too close. The plasterboard wall inside this garage had been damaged by a car, and it needed a proper repair, not just filler.
The garage wall repair job
I patched the damaged area, set it in layers and feathered it out wide so the repair finishes flat and smooth with the rest of the wall.
4 proven steps for a smooth garage wall repair
- Remove loose material. Broken plaster and torn paper are cut back to a sound edge.
- Patch or back the hole. Small damage is patched; larger damage gets backing and a new piece of plasterboard.
- Set in layers. Several thin coats of compound, each left to dry, rather than one thick coat that can crack or shrink.
- Feather it out wide. The final coats are spread well past the damage so there is no hump, then sanded smooth ready for paint.
Check what’s behind the wall
If a car has hit the wall hard, it is worth checking the framing too. Garage walls can also have power points, switches or cabling, and any damaged electrical fittings need a licensed electrician.
Stop it happening again
A wheel stop, a parking mat or a simple marker on the wall can help prevent the next bump.
