How do I fill small holes or cracks in walls?
Nail holes, screw holes, and hairline cracks are the most common wall imperfections. Fixing them properly before painting gives a smooth, professional finish.
- Use standard spackling compound with putty knife and sandpaper5
Apply pre-mixed spackling compound into nail holes, screw holes, dents, and hairline cracks using a flexible putty knife, then sand smooth once dry. This is the most common and reliable method for small wall repairs in drywall and plaster.

π οΈ Spackling compound (standard or lightweight), flexible putty knife (1.5 or 3 inch), 220-grit sandpaper, sanding block, damp cloth or tack cloth, primer, matching wall paint, paintbrush or small roller
- Use white toothpaste for emergency pinhole repairs2
Squeeze a small amount of white, non-gel toothpaste onto your fingertip. Press it into a tiny nail hole or pinhole and smooth it flat with your finger or a damp cloth. Wipe away excess. The toothpaste dries to a white, semi-hard fill that conceals the hole temporarily.

- Use bar soap or matching crayon for quick cosmetic concealment1
Rub a bar of white soap or a wall-color-matched crayon firmly over a tiny nail hole or pinhole until the material fills the void. Wipe away excess with a dry cloth. The soap or wax fills the hole and blends with the wall color from normal viewing distance.

- Hire a drywall professional for larger damage4
For holes larger than 4-5 inches, extensive cracking, water damage, or textured walls that need matching, a drywall professional will cut out the damaged section, install a new piece, tape and mud the joints, and match the existing texture.

- Use setting-type compound for deep or recurring repairs4
Mix powdered setting-type joint compound (like Durabond or Easy Sand) with water and press it into deep holes, wide cracks, or areas where lightweight spackle has failed repeatedly. It sets by chemical reaction and can be built up in thicker layers than regular spackle.

- Seal hairline cracks with paintable caulk4
Run a thin bead of paintable acrylic latex caulk along hairline cracks where walls meet trim, ceilings, or corners. Smooth the bead with a wet finger and let it dry. Paint over it once cured.

- Patch medium holes with a self-adhesive mesh patch4
For holes 1-4 inches across (like doorknob damage or old anchor holes), stick a self-adhesive fiberglass mesh patch over the hole. Apply joint compound over the mesh with a wide putty knife, feathering the edges outward. Let dry, apply a second coat, sand smooth, prime, and paint.

- Use wood filler for holes and cracks in trim, baseboards, and molding4
For nail holes, cracks, dents, and gaps in wood trim, baseboards, window casings, and crown molding, use a stainable or paintable wood filler rather than wall spackle. Press the filler into the hole or crack with a putty knife or your finger, overfilling slightly. Let it harden fully, then sandβ¦

Apply a pre-mixed lightweight spackling paste (such as DAP DryDex or 3M Patch Plus Primer) directly into nail holes, screw holes, or hairline cracks using a flexible putty knife. Lightweight spackle contains microspheres or air-filled particles that make it less dense than standard spackle, so itβ¦
