Repair Small Holes
- First we enlarge the hole to make it a rectangular shape, so that it is easy to fit a plaster patch that’s the same shape.
- Then we attach new timber or a furring to the inside of the hole, so that we can then screw the plaster patch securely in place.
- Next we apply paper tape and three layers of plaster. Each layer must dry before next one is applied.
- Finally we sand it back to a smooth finish so that the repair won’t be noticeable after it has been painted.
Repair Large Holes
Fixing a large hole in a plaster wall or ceiling can be very similar to repairing a small hole, the main difference being that we will cut out a rectangle hole that is the width of the gap between the wall studs, so that we can then easily screw the new plaster patch to the wooden studs on either side.
For holes that are even larger, it is sometimes easier to replace the entire sheet of gyprock, rather than trying to patch it. Replacing an entire sheet requires two people to lift it into place. Sometimes it may be necessary to also remove and then re-apply the cornice.
Repair Water Damaged Plaster
Repairing water damaged wall or ceiling can be tricky because we may need to replace more than just the part that is bulging out. Gyprock soaks up water like a sponge and may not be as strong once it dries out. So for water damaged ceilings we need to also replace the area around the bulging part, to prevent it falling on someone in the future.
It may be necessary to use a moisture reader to check whether there’s any moisture left in the plaster surrounding the hole to be replaced. If there is, we need to wait a few days for it to dry completely, to prevent the new plaster reacting with the moist plaster.
Plaster Crack Repairs
- If the house is moving or sinking, the joints are always going to crack.
- Excessive expansion and contraction due to temperature differences.
- Rooms with over 3 or 4 joints needs to be back blocked.
- No support behind the joint.
- Expansion joints must be added if there’s more than a certain length of plaster.
Repair Plaster Cornices
- If the ceiling is not quite level because it is more difficult to cut the new and old cornice at the correct angles so that they match up correctly (especially if the cornice is patterned).
- When attaching cornice to a painted surface it’s best to apply a coat of diluted bondcrete first.
Repair Bulging Plaster Wall
- Plaster is incorrectly screwed to the wall frame.
- Plasterboard sheets are installed too close together.
- The house is settling.
- It has been damaged by water.
- Previous repairs weren’t done correctly.
An expert plasterer will quickly be able to spot the cause of the damage and apply the appropriate type of repair.
What Thickness Plaster / Gyprock
The first step of repairing any damaged plaster is to acertain whether it is 10mm, 13mm or 16mm thick. These days most plaster is 10mm thick (especially ceilings), and 16mm is usually only used when fire resistance or sound-proofing is needed.
