Step-by-Step Instructions
1. Find the Spot You’re Fixing
Look for:
- A nail pop — a round bump, crack, or dimple in the wall
- A settling crack — usually a thin line, often near doors, ceilings, or corners
Touch around the spot.
If the wall feels soft or mushy, it may need more than a patch. If it’s firm with just a visible flaw, you’re good to go.
2. Scrape Off Any Loose Stuff
Use a putty knife or utility knife to gently scrape away:
- Paint flakes
- Cracked drywall compound
- Loose drywall paper
For nail pops:
If there’s a screw sticking out, either:
- Tighten it until it’s slightly recessed
- Or remove it and add a new drywall screw 1″ above or below
Tip: Don’t stress about getting it perfect. The next step smooths it all out.
3. Apply Joint Compound (Thin Layer First)
Use a small putty knife and spread a thin layer of joint compound over the spot.
- Cover the area, then feather (spread) the edges out an inch or two
- For cracks, press compound into the line and smooth over
- For nail pops, cover the hole and spread about 4″ around it
Let it dry for 1–2 hours (check your compound label).
It won’t look perfect yet — that’s normal.
4. Lightly Sand the Area Smooth
Use a sanding sponge or sanding block (medium grit) to smooth the surface.
- Use light pressure — don’t dig in
- Run your hand across the area to check for bumps or edges
💡 Pro Tip: Hold a flashlight sideways to spot uneven areas. It’ll highlight any ridges before painting.
5. Add a Second Coat (If It Needs It)
If it looks uneven or sunken:
- Apply a second, slightly wider coat of compound
- Feather the edges again
- Let it dry and sand lightly one more time
Most spots need two coats — that’s totally normal.
6. Prime and Paint to Finish
Before painting:
- Apply a light coat of drywall primer (this seals the compound)
- Let it dry fully
- Then touch up with your wall paint
⚠️ Don’t skip the primer:
If you paint directly over the patch, it might show through as a dull or shiny spot — that’s called flashing.
Cleanup
Wipe the wall with a slightly damp cloth to remove dust before painting
Rinse your putty knife and sanding block with water right after using

Pro Tips
✅ Pro Tips:
- Use setting-type joint compound (like 20-minute mud) for deeper cracks or problem areas — it dries harder and shrinks less.
- Slightly recess the screw head when fixing nail pops, but don’t break the paper — you want the compound to grip, not crack.
- Feather your edges wide when applying compound so the repair blends seamlessly into the surrounding wall.
- Lightly mist with water before sanding to cut down on dust — or use a sanding sponge with a dust catcher.
- Prime patched areas before painting — bare compound can cause uneven color and texture if skipped.
❌ Mistakes to Avoid:
Using spackle on large cracks or pops — spackle isn’t strong enough for deep repairs; use joint compound instead.
Skipping fasteners on both sides of the nail pop — always install at least one screw above and below the pop to lock it in.
Applying compound too thick in one go — it leads to shrinkage cracks or longer dry times.
Sanding too early — make sure the patch is completely dry or you’ll rip the surface and create more work.
Neglecting hairline cracks — they may seem small but can spread or reopen if not properly patched.
Drywall Repair Essentials
Patch drywall cracks and nail pops cleanly and confidently with the right gear:
- 6″ or 8″ Taping Knife – for smooth compound spreading and feathering
- Drywall Joint Compound – all-purpose or setting-type (like 20-minute)
- Sanding Sponge or Pole Sander – to smooth the repair without gouging
- Drywall Screws & Drywall Bit – for re-securing popped nails or loose drywall
- Mesh Drywall Tape – ideal for covering longer cracks without bubbling
- Primer for Patched Walls – prevents flashing and uneven paint
- Dust Mask or Respirator – keep lungs safe while sanding
