HomeCostGuideHow to Patch a Hole in Drywall
The right patch method depends on hole size. Small holes just need spackle; anything bigger than a couple inches needs a patch backing to hold its shape.

Steps
- 1
Clean up the hole
Remove any loose or crumbling drywall around the edges with a utility knife so you're working with a stable edge.
- 2
Choose your patch method
For holes under an inch, spackle alone is enough. For larger holes, apply a self-adhesive mesh patch or a rigid patch kit over the opening first.
- 3
Apply the first coat
Spread joint compound or spackle over the patch with a putty knife, feathering the edges out beyond the damaged area so it blends into the surrounding wall.
- 4
Let it dry and sand
Allow the compound to dry fully per the product's instructions, then sand smooth with a sanding block, checking for flatness with your hand.
- 5
Apply additional coats as needed
Larger repairs usually need 2–3 thin coats, each sanded smooth, rather than one thick coat that's prone to cracking.
- 6
Prime and paint
Prime the patched area (patched drywall absorbs paint differently than the surrounding wall) before applying matching paint.
Safety notes
- Wear a dust mask when sanding dried compound.
When to call a pro
Holes larger than about a foot across, or damage that reveals water staining or mold behind the drywall, are worth having a professional assess before you patch over a bigger underlying problem.
Frequently asked questions
What's the difference between spackle and joint compound?+
Spackle is thicker and better for small holes since it shrinks less. Joint compound spreads more easily over larger areas and is standard for patches that need a mesh or paper backing.
Why does my patch show through the paint?+
Unprimed patched drywall absorbs paint differently than the surrounding wall, creating a visible flat spot (often called 'flashing'). Priming the patch before painting solves this.
