How to Fill Large Holes in Plasterboard Walls

Filling large holes in plasterboard walls is an essential skill for any homeowner. Whether you're repairing damage from a doorknob or a burst pipe, it's important to know how to patch the hole properly so that it's strong and invisible.

In this article, we'll walk you through the essential steps of filling large holes in plasterboard walls. We'll cover everything from gathering the right materials to applying the final coat of paint.

Materials You'll Need

Plasterboard repair patch
Joint compound
Joint tape
Putty knife
Sandpaper
Primer
Paint

Step 1: Clean the Hole

The first step is to clean the hole of any debris. Use a vacuum cleaner to remove any loose dust or dirt.

Step 2: Cut the Repair Patch

Next, cut a repair patch that is slightly larger than the hole. The patch should be made of plasterboard or another suitable material.

Step 3: Apply the Joint Tape

Apply a strip of joint tape over the edges of the hole. The joint tape will help to reinforce the patch and prevent it from cracking.

Step 4: Apply the Joint Compound

Spread a thin layer of joint compound over the joint tape and the repair patch. Use a putty knife to smooth out the compound.

Step 5: Let the Joint Compound Dry

Allow the joint compound to dry completely. This may take several hours or even overnight.

Step 6: Sand the Joint Compound

Once the joint compound is dry, sand it smooth. Use a fine-grit sandpaper to avoid damaging the surface of the wall.

Step 7: Prime the Wall

Apply a coat of primer to the repaired area. The primer will help to seal the joint compound and make the paint adhere better.

Step 8: Paint the Wall

Finally, paint the repaired area to match the rest of the wall. Use a brush or roller to apply the paint evenly.

Filling large holes in plasterboard walls is a simple process that can be completed in a few hours. By following these steps, you can repair the hole quickly and easily, and restore the wall to its original condition.
