  • Gyprock Easy tape (self-adhesive jointing tape)
  • 100mm broad knife
  • Sanding block
  • Mixing bucket
  • Your instruction book

3 Steps to fixing small holes on plasterboard or masonry walls

Fixing a hole in the wall by yourself is as easy as one, two, three. Follow the steps below and enjoy smooth walls for years to come.

Step 1. Prepare the hole and rapid patch mixture

Prepare the rapid patch mixture in your bucket, bringing it to a creamy consistency (it should be able to hold itself on the broad knife without falling off). If it’s a small hole (think iPhone charger size), apply the mixture directly to the wall with the broad knife. Keep in mind there needs to be something directly behind the area you’re filling – otherwise, it’ll simply fall into the hole (think whether your home is made up of plasterboard directly stuck to brick or timber frame?). Allow this to dry.

Step 2. Apply Gyprock Easy Tape

Once it’s dry, apply a strip of Gyprock Easy tape to cover the hole (this has an adhesive backing).

Step 3. Apply two layers rapid patch and sand to smooth

Apply two coats of rapid patch over the tape, allowing it to dry in between coats. Sand down to a smooth finish and dust the surface before applying the next coat. Once this is complete your wall is ready for painting. Keep in mind this process is dusty and can be quite messy – so be sure to use a drop sheet or some cardboard to protect your finished floor.

Identifying your wall type

Before you begin, you’ll need to understand what kind of wall you’re working with, be it timber-framed, brick, weatherboard, or steel-framed.
Identifying the type of wall is critical because there are different ways to fix different-sized holes and there are also different ways to patch cracks and bumps in walls. As a rule, compounds shouldn’t be applied in thick clumps. What tends to happen when it’s applied like this is that it’ll crack; the moisture in the mixture will dry out meaning your finished product will also crack once everything dries.
Larger holes also need to be built out one step at a time, so you may even need to call on something like cornice cement or stud adhesive for the first couple of coats to avoid the base and top coats cracking. If in doubt, always call in the experts.

5 Tips for fixing large holes in plasterboard walls:

  1. Along with the rapid repair kit pick up a Gyprock Mini-Repair Panel and trim it to size (this should be slightly smaller than the hole itself, which now needs to suit the repair panel size). Trace an outline around the panel onto the existing plasterboard wall and set it aside. The patch and offcuts are for use later.
  2. Cut the damaged area away to the outline you’ve drawn (this is where your Gyprock saw comes in). Note: Slow and steady wins the race here, don’t do more damage to your wall by going crazy on it.
  3. With the panel offcuts noted above, create two backing blocks and fix them to the inside of the hole with a small amount of rapid patch adhesive and leave this to go off (dry). Once you can apply light pressure to the back blocks (four hours), fix the pre-cut patch into the hole with more rapid patch as the adhesive.
  4. As per the steps above, cover the joins with Easy tape (this stops the compound from cracking) and apply two coats of rapid patch, allowing them to dry between coats.
  5. Lightly sand each coat and now you’re ready to paint.
    Note: You’ll need a serrated Gyprock saw for this, approx. $15.
