Fibre-cement cladding – impact damage

Cause

Stones, balls, human impact, vehicles

Repair

  • for small holes up to approximately 30 mm diameter, fill with exterior grade flexible (polyester) filler; wet sand; prime; paint with a minimum two coats of semi-gloss or high gloss acrylic paint
  • for larger holes, trim the hole to a regular shape, removing all damaged fibre-cement; cut two strips of fibre-cement; glue across the top and bottom of the hole at the back of the cladding using exterior grade construction adhesive (for a small hole, one piece fixed across the centre will be enough); cut a third piece to fit neatly inside the hole; glue in place against the backing fibre-cement pieces; fill around the patch with exterior grade flexible (polyester) filler; wet sand; prime; paint with a minimum two coats of semi-gloss or high gloss acrylic paint
