Clear finish failure on timber

Cause

UV light causing breakdown of the timber surface under the clear finish

Repair

  • sand to remove loose finish; reseal, particularly the ends of timber if possible

Cause

Moisture was absorbed into the timber, typically at the ends of boards or around fixing points

Repair

  • identify and address cause of moisture - leak or condensation; allow timber to dry; sand and reseal. Where it is suspected that the building may be leaking and there is a risk of damage engage an experienced building surveyor to report on the building
