Repairing holes in plasterboard

patching hole in plasterboard

A plasterer would typically fix a hole in the wall using the following steps:


  1. Prepare the hole: The plasterer will remove any loose debris and debris around the hole. If the hole is large, they may need to install a backing board to provide a stable surface for the repair.

  2. Mix the plaster: The plasterer will mix the plaster to the right consistency according to the manufacturer’s instructions.

  3. Apply the plaster: The plasterer will apply the plaster to the hole, using a trowel to smooth and shape the plaster. They will work in small sections and ensure that the plaster is pressed firmly against the wall to create a strong bond.

  4. Sand and finish: After the plaster has dried, the plasterer will sand the surface to smooth out any imperfections and to ensure that the repair is flush with the surrounding wall. They will then apply a final coat of plaster and smooth it out with a trowel.

  5. Paint or paper: Once the plaster is dry, you can paint or paper over the repair to match the surrounding wall.


repair crack in plasterAfter plastering, you should typically wait at least 24 hours before painting (or papering) over it. This allows the plaster to fully dry and set, which will ensure that the paint adheres properly and dries evenly. If the plaster is still wet or not fully set, the paint may not adhere properly or may dry unevenly, resulting in an unsightly finish. It’s also important to note that, if the plastering is done in a humid environment, the drying time may be longer. In this case, it’s best to check with a plastering professional or the manufacturer’s recommendations before painting.


It’s important to note that the size of the hole and the type of plaster used will determine the techniques and tools needed for the repair. If the hole is small and in a drywall, a patching compound can be used to repair the hole, if the hole is larger or in a plaster wall, the plasterer may need to use a different technique.


It’s also important to note that if the hole is caused by a structural problem or a plumbing problem, it is necessary to address the problem before fixing the hole, otherwise the problem will persist.

apex plasterers toowoombaWhy you need to make sure it’s done right.

Proper plastering is important because it plays a critical role in the overall structural integrity and appearance of a building. Incorrect plastering can lead to a number of problems, such as:

    1. Moisture damage: Poorly applied plaster can allow moisture to seep into the walls and ceilings, leading to mold and mildew growth, which can be detrimental to the health of occupants and can cause structural damage.
    2. Aesthetics: Improper plastering can result in uneven surfaces, bulges, and other unsightly imperfections, which can detract from the overall appearance of the building and negatively impact property values.
    3. Safety hazards: In case of fire, improperly plastered walls and ceilings can burn quickly and spread fire rapidly, putting the building’s occupants at risk.
    4. Costly repairs: If plastering is not done correctly, it can lead to costly repairs down the line.

How can you tell if your plastering has been done right?

  • Smooth and even surfaces: Properly applied plaster should have a smooth and even surface, free from bulges, ridges, or other imperfections.
  • Straight edges: Corners and edges of walls and ceilings should be straight and clean, with no rough or uneven edges.
  • Proper curing: Plaster should be allowed to cure for the appropriate amount of time before being painted or wallpapered. If the plaster is painted or wallpapered too soon, it can lead to cracking, peeling, and other issues.
  • No cracking: Properly applied plaster should not crack, and if it does, it’s a sign that the plaster was not applied correctly or the surface was not properly prepared.
  • No sagging: The plaster should be applied to a level surface, without any sagging or drooping.
  • No holes or gaps: There should be no holes or gaps in the plaster, as these can allow moisture to penetrate the wall and cause damage.

It’s important to note that if you suspect that your internal plastering has been done incorrectly, it’s best to consult with a professional plastering team to assess the situation and make recommendations for repairs.
