Step-by-Step Guide - How to Fix a Large Hole in Drywall

Step 1: Prepare the Area

Start by cleaning up the area around the hole. Remove all loose dust and debris. A clean surface will ensure that the patch adheres well, increasing the likelihood of a successful repair.

Step 2: Square the Hole

Use your drywall saw to square off the edges of the hole. This means making the hole a clean, rectangular shape. A well-defined hole will help you fit the patch perfectly and will lead to smoother results. Take your time—accurate cuts make a big difference.

Step 3: Cut the Patch

Cut a piece of drywall slightly larger than your squared hole. For instance, if your hole measures 6 inches by 8 inches, cut a patch that measures about 7 inches by 9 inches initially. You can always trim it down if necessary.

Step 4: Add Backing Strips

You will need to secure backing strips for extra support. Cut two strips of wood or metal, slightly longer than the hole's height, around 8 to 10 inches will do. Insert these into the wall cavity and secure them with screws. This provides a solid base for attaching your patch.

Step 5: Secure the Patch

Place your patch into the hole, ensuring it is affixed to the backing strips. Use screws to secure it in place. Make sure the patch is flush with the surrounding wall to create a seamless appearance.

Step 6: Apply Joint Compound

With your putty knife, spread a layer of joint compound over the patch and the seams. This initial layer acts as a base coat. You don't need it to look perfect; its main purpose is to fill gaps.

Step 7: Sand and Repeat

Once the joint compound has dried—usually 24 hours, but check the package instructions—sand it down until smooth. Apply a second layer of joint compound, feathering it out beyond the edges to create a gradual slope. Repeat as necessary until the surface is perfectly smooth, which may take 2 to 3 layers.

Step 8: Final Sand and Prime

After the last layer of joint compound has dried, lightly sand the area. This ensures an even finish. Apply a coat of primer before painting; this step is important, as primer helps the paint adhere better and ensures an even color across the wall.
