Diagnosis

Cracks in drywall are a frequent household problem, typically stemming from the house settling, minor bumps, or shifts in temperature and moisture. These blemishes can detract from your home's appearance and might grow larger if not dealt with. Fortunately, fixing them is a manageable do-it-yourself task that can greatly enhance your home's look.

Tools Needed

  • Putty knife
  • Sanding sponge (medium and fine grit)
  • Utility knife
  • Drywall joint compound (spackle)
  • Painter's tape
  • Drop cloth
  • Primer
  • Paint

Warnings

  • Always wear safety glasses when sanding to protect your eyes from dust.
  • Ensure good ventilation when working with joint compound and primer.
  • Allow adequate drying time between coats to prevent cracking or peeling.

Step-by-Step Instructions

  1. Cover the area around the crack with a drop cloth to protect surfaces.
  2. Carefully widen the crack into a 'V' shape using a utility knife. This step ensures the patching material adheres more effectively.
  3. Remove any loose particles or dust from within the widened crack.
  4. Using a putty knife, apply a thin, uniform layer of joint compound directly into the 'V' groove, pressing it in securely.
  5. Remove excess compound and smooth the edges outward, blending them into the surrounding wall.
  6. Let the joint compound dry completely, following the product's guidelines (typically a few hours).
  7. Once dry, gently sand the patched section with a medium-grit sanding sponge until it feels smooth and level with the wall.
  8. Wipe away any sanding dust with a slightly damp cloth.
  9. If necessary, apply a second thin layer of joint compound to achieve a perfectly smooth surface, and allow it to dry.
  10. Sand this second layer with a fine-grit sponge and clean the area again.
  11. Apply a layer of primer over the repaired spot.
  12. After the primer dries, paint the area to match the existing wall color.

Troubleshooting

  • If the crack reappears after drying, it might be due to ongoing house movement. Try applying a second or third layer of joint compound, feathering the edges wider each time. For larger cracks, consider using drywall tape before applying the compound.
  • If the patched area is still visible after painting, it may not have been sanded smoothly enough or the primer/paint isn't an exact match. Lightly sand the area again, re-prime, and re-paint, ensuring you feather the paint edges.

Preventive Tips

  • Monitor your home for significant changes in temperature or humidity, which can cause materials to expand and contract.
  • Address any structural issues in your home promptly, as they can lead to more severe drywall damage.
  • Avoid hanging excessively heavy items on drywall without proper anchors.
