How to Fix a Large Drywall Hole

Instructions for Repairing a Large drywall Hole

By Mark J. Donovan

In this video I show how to fix a large drywall hole associated with a new gas fireplace and natural stone surround installation project.

I am making the drywall repair so that the drywall hole is not visible from underneath the fireplace mantle.

Insert Sticky Drywall Mesh Tape into Drywall Hole

To start out with this large drywall hole repair fix I am stuffing the hole with some folded up sticky drywall mesh tape. 

The tape acts as a binder, or rebar if you will, for ensuring the joint compound has something to attach to.

If I didn’t use the drywall mesh tape then the joint compound would most likely crack and fall out of the hole over time.

Apply Drywall Joint Compound to Hole

Next, I use a one-inch putty knife to apply drywall joint compound into the hole, making sure to squeeze it in tight and that it fully absorbs into the bed of drywall mesh tape and fills the void.

I then immediately follow up and apply a little more joint compound over the area with a three-inch drywall taping knife.

After applying the drywall joint compound, I let it set up for 24 hours.

Apply Second Coat of Drywall Joint Compound to Hole

The next day I use my 3-inch drywall taping knife again and apply a skim coat of additional joint compound over the drywall hole repair area.

Again, I let the drywall joint compound set-up overnight.

Lightly Sand Drywall Joint Compound

The next day I lightly sand the drywall hole area, using a foam sand block, by first focusing on the outer edges of the drywall hole repair area and then moving in over the center of the repaired drywall.

Prime and Paint Fixed Large Drywall Hole Area

After sanding the drywall joint compound, I applied a primer over the joint compound and repaired drywall hole area. After allowing some time for the primer to dry, I applied a coat of paint over it to complete the process of fixing a large drywall hole.
