Drywall damage is one of the most common — and most fixable — issues homeowners face. Whether it’s a nail hole, a small dent, or a large crack, you don’t need to call in a contractor. With a few basic tools and a bit of time, you can make your walls look brand new again.
This DIY guide will walk you through simple and effective methods to repair holes and cracks in drywall, so you can restore your walls with confidence.
What You’ll Need
Before you get started, gather these materials:
- Spackle or joint compound
- Drywall patch or mesh tape
- Putty knife (2–6 inches wide)
- Sanding block or sandpaper (120–220 grit)
- Primer and matching paint
- Paintbrush or roller
- Utility knife
- Dust mask and drop cloth (optional, but helpful)
Repairing Small Holes (Nail or Screw Holes)
These are the easiest to fix and don’t take much time:
Step-by-Step:
- Clean the Hole
Remove any loose debris with your finger or a utility knife. - Apply Spackle
Using a putty knife, apply a small amount of spackle over the hole, pressing it in and smoothing it flat. - Let It Dry
Allow it to dry completely (usually 30 minutes to 1 hour, or as per product instructions). - Sand Smooth
Gently sand the area until flush with the wall. - Prime and Paint
Prime if needed, then apply matching wall paint.
Pro Tip: For walls that haven’t been painted in a while, feather your paint outward to blend better.
Repairing Medium Holes (1–5 Inches)
For holes from door handles or small accidents:
Step-by-Step:
- Attach a Drywall Patch or Mesh Tape
Use a ready-made patch or fiberglass mesh tape over the hole. - Apply Joint Compound
Smooth over the patch with joint compound, feathering the edges. - Let It Dry & Sand
Dry fully before sanding the surface until smooth and level. - Repeat If Needed
You may need a second layer for seamless results. - Prime and Paint
Apply primer and paint over the patched area.
Pro Tip: Use a wide putty knife for better blending and fewer ridges.
Repairing Large Holes or Cracks (Over 5 Inches)
These require a bit more effort, but you’ve got this:
Step-by-Step:
- Cut a Drywall Patch
Use a utility knife to cut a square around the damaged area. Measure and cut a new piece of drywall to fit. - Secure with Backing or Furring Strips
Insert wood strips behind the wall opening and screw the drywall patch into them. - Tape the Seams
Apply drywall tape around the edges to help the compound adhere smoothly. - Apply Joint Compound in Layers
Apply thin layers of compound, letting each dry before sanding and adding the next. - Sand, Prime, and Paint
Once it’s smooth, finish with primer and paint.
Pro Tip: Skim coat the area with a thin compound layer for a perfectly smooth finish.
Bonus: Fixing Hairline Cracks
Hairline cracks often appear near ceilings or corners due to settling:
- Widen the crack slightly with a utility knife.
- Fill it with lightweight spackle.
- Sand, prime, and paint as usual.
