DIY Wall Repair Tips

From concealing screw holes to tackling blistered paint, follow these DIY tips to fix your problematic wall surfaces.

CONCEALING HAIRLINE CRACKS & SCREW HOLES

  1. Remove loose plaster and widen cracks, if necessary.
  2. Using a putty knife, apply joint compound to the cracks. Allow to dry overnight.
  3. Use fine-grit sandpaper to evenly sand the area and remove bumps.
  4. If needed, apply second layer, let it dry and re-sand.
  5. Paint as required.

GETTING RID OF CHALKING (mould that appear as powdery white streaks)

  1. Dilute half-cup of bleach in 4.5 litres of water.
  2. With an abrasive scrubber, use the diluted bleach to remove mould growth. Allow wall to dry.
  3. Wipe affected surface with a mixture of vinegar and water (1:4) to re-harden the plaster. Allow wall to dry.
  4. Coat with primer and paint over.

REMOVING BUBBLED & BLISTERED PAINT

  1. Pop paint blisters with a putty knife and peel the loose material away.
  2. Remove residue by wiping with a clean cloth and warm water.
  3. Gently sand edges.
  4. Apply joint compound if needed.
  5. Apply primer and paint.

Remember, prevention is better than cure! When possible, use adhesive hooks and hanging strips instead of drilling holes. Also, don't hesistate to call in a professional if your wall surface is badly damaged or the mould growth is widespread and has turned black!
