Construction Performance Guidelines
WOOD OR HARDBOARD OR PANEL-TYPE SIDING - FASTENERS ARE EXCESSIVELY COUNTERSUNK INTO FINISHED SURFACE
Siding fasteners shall be installed in accordance with the manufacturer’s specifications, where applicable, and shall not expose hardboard siding fibre.
One-Year - Work and Materials
Siding with nails not meeting the acceptable condition shall be repaired.
Nails that have been excessively countersunk detract from the overall appearance of the finished surface. This condition can lead to premature deterioration of the product by allowing water to accumulate in the holes left by the nailheads.
