How to Repair Drywall: The Complete Homeowner's Guide From Nail Holes to Large Wall Repairs
Drywall damage is one of the most common home repairs homeowners face. Whether it's a small nail hole from hanging pictures, a dent from moving furniture, or a larger hole caused by an accident, learning how to repair drywall can save money and help keep your home looking its best.
The good news is that many drywall repairs don't require expensive tools or years of experience. With a few basic supplies and some patience, most homeowners can tackle simple drywall repair projects themselves.
In this guide, we'll explain everything from filling nail holes to replacing larger sections of damaged drywall, along with when it may be time to call a professional.
Step 1: Identify the Type of Drywall Damage
Before grabbing tools, determine what kind of damage you're dealing with.
Tiny Holes (Less Than ¼ Inch)
Examples: Picture hanging nails, Push pins, Small screws
These are the easiest drywall repairs and typically only require spackle.
Small Holes (¼ Inch to 2 Inches)
Examples: Wall anchor holes, Minor dents, Small impacts
These may require spackle, joint compound, or a small mesh patch.
Medium Holes (2 to 6 Inches)
Examples: Furniture damage, A child accidentally kicking the wall, Door handles hitting drywall
These repairs usually require a mesh patch and joint compound.
Large Holes (6 Inches or Larger)
Examples: Plumbing repairs, Water damage removal, Significant accidents
These repairs often require replacing a section of drywall.
Step 2: Gather Your Tools
You don't need professional equipment to complete most drywall repairs.
Basic Tools
Putty knife
Utility knife
Sanding sponge
Measuring tape
Pencil
Drill or screwdriver
Drywall screws
Helpful Tools
Drywall saw
Stud finder
Mud pan
Drywall taping knife
Household Alternatives
Don't want to buy specialty tools? No mud pan? Use a paper plate. No sanding block? Wrap sandpaper around a scrap piece of wood. No drywall saw? A sharp utility knife will work for many repairs. No paint tray? Use a disposable aluminum baking pan.
Step 3: Gather Your Materials
You'll likely need some combination of these materials.
Spackle - Best for: Nail holes, Tiny dents, Small cosmetic repairs
Joint Compound (Mud) - Best for: Larger repairs, Seams, Mesh patches
Drywall Tape - Used to strengthen seams and prevent cracking.
Self Adhesive Mesh Patches - Great for medium sized holes.
Drywall Pieces - Necessary for larger repairs.
Drywall Primer - Used before painting larger patches.
Can You Use Toothpaste to Repair Drywall? Technically, yes. Should you? No. While toothpaste is a common internet hack, it isn't designed for permanent drywall repair. It will eventually crack, shrink, and fail over time. Instead, purchase a small container of spackle. It's inexpensive and designed specifically for this purpose.
How to Repair Nail Holes
Remove any loose debris.
Apply a small amount of spackle.
Scrape excess material away with a putty knife.
Allow it to dry.
Lightly sand the area smooth.
Touch up the paint.
For tiny repairs, you usually won't need primer.
How to Repair Small Holes
Remove loose drywall paper.
Fill the hole with spackle or joint compound.
Build up thin layers instead of one thick application.
Allow it to dry completely.
Sand smooth.
Paint.
How to Repair Medium Sized Drywall Holes
Place a self-adhesive mesh patch over the hole.
Apply joint compound over the patch.
Feather the edges several inches beyond the repair.
Allow it to dry.
Apply a second coat.
Sand smooth.
Prime.
Paint.
Take your time during this process. Multiple thin coats will always produce a better finish than one thick coat.
How to Repair Large Drywall Damage
Locate the Studs
Use a stud finder to locate nearby framing members.
Cut a Square or Rectangle
Remove damaged drywall by creating a clean square or rectangular opening.
Cut Your Replacement Piece
Use the removed drywall as a template.
Install Backing
If a stud isn't available, install wood backing behind the drywall.
Secure the New Drywall
Use drywall screws to attach the new piece.
Tape the Seams
Apply drywall tape to all joints.
Apply Joint Compound
Use multiple thin coats instead of one thick coat.
Allow each coat to dry before adding another.
Sand Smooth
Use a sanding sponge to feather the edges.
Prime
Large repairs almost always require primer.
Paint
Apply matching paint to blend the repair into the surrounding wall.
When Do You Need Drywall Primer?
Use drywall primer when:
Installing new drywall
Repairing large holes
Covering large amounts of joint compound
Repairing bare drywall paper
You can often skip primer on a single nail hole. Without primer, patched areas may absorb paint differently and remain visible. This is called flashing.
DIY Drywall Repair or Hire a Professional?
A homeowner can usually tackle:
Nail holes
Small dents
Minor patches
Single room touchups
Consider calling a professional if:
Water damage is involved
Mold is present
Ceiling drywall is damaged
The hole is larger than 6 inches
You need texture matching
There are multiple repairs throughout the house
You don't have matching paint
Drywall repairs may seem simple, but blending textures and creating an invisible repair often takes experience.
