Stucco – random hairline cracking

Cause

Shrinkage as a result of incorrect plaster mix and/or inadequate curing

Repair

  • monitor cracking  for one month:
    • if no further cracking occurs, paint with a high-build acrylic coating
    • if cracking is still occurring or cracks are getting wider, obtain specialist advice
  • if moisture entry is suspected, check for increased moisture levels in the walls; assess the extent of any damage found
  • where it is suspected that the building may be leaking and there is a risk of damage behind the cladding, engage an experienced building surveyor to report on the building

Cause

Excessive trowelling during application

Repair

  • monitor cracking  for one month:
    • if no further cracking occurs, paint with a high-build acrylic coating
    • if cracking is still occurring or cracks are getting wider, obtain specialist advice
  • if moisture entry is suspected, check for increased moisture levels in the walls; assess the extent of any damage found
  • where it is suspected that the building may be leaking and there is a risk of damage behind the cladding, engage an experienced building surveyor to report on the building

Cause

No movement control joints installed

Repair

  • monitor cracking for one month:
    • if no further cracking occurs, paint with a high-build acrylic coating
    • if cracking is still occurring or cracks are getting wider, obtain specialist advice
  • if moisture entry is suspected, check for increased moisture levels in the walls; assess the extent of any damage found
  • where it is suspected that the building may be leaking and there is a risk of damage behind the cladding, engage an experienced building surveyor to report on the building

Cause

Building movement or settlement

Repair

  • where it is suspected that the building may be leaking and there is a risk of damage behind the cladding, engage an experienced building surveyor to report on the building

Cause

Building subjected to vibration movement such as earthquake, high wind

Repair
