PRE-INSTALLATION
4.1 ON-SITE STORAGE AND HANDLING
Care must be taken to ensure that timber and accessories are kept clean and dry, and are not damaged
whilst in storage awaiting application.
Extra care is to be taken while handling timber to ensure that it is not damaged.
Timber is to be stacked on flat level bearers/dunnage
that is a maximum of 900mm apart and at least
100mm off the ground. Timber should either be stored inside an enclosed building or covered with an
additional waterproof layer and protected from the elements when stored outside
IMPORTANT
Radiata Pine weatherboards should not be installed if their moisture content is above
20%.
4.2 DOCKING OUT DEFECTS
Before coating or installing boards, check for any defects that may require docking out.
IMPORTANT
All docked ends, any exposed or bare timber of painted weatherboards will require end
sealing with a minimum of two coats of primer.
4.3 PRIMING AND SEALING
Apply the first coat of primer to all sides and edges of the weatherboard prior to installation. It is critical that
Radiata Pine is at the correct moisture content prior to priming. Remember that all docked ends will require
priming as noted above. Follow the coating manufacturer’s directions and ensure further coats are applied
as required. All relevant sections of standard AS/NZS 2311 (Guide to the painting of buildings) must be
adhered to.
