The moisture content must not exceed 15% at time of installation. Note: Generation 2 H3.2 products are made from kiln dried timber. Timber will absorb moisture in a damp environment and release it in a dry environment. If Generation 2 H3.2 products do absorb moisture prior to installation, dimensional swelling may occur, this will disappear when the timber returns to its original moisture content. -
Page 8: Life Serviceability
The life service is subject to correct installation, paint coating of the product, maintenance and care. When KLC Generation 2 weatherboards are installed according to the instructions contained in this manual and by a Licenced Building Practitioner (LBP) or suitably qualified person, the service life can be expected to be considerably longer. -

If the moisture content is above 15% then the product should not be installed until it returns to 15% or less. -
Page 11: Nail Selection
Guidelines for Installation 3.3 Nail Selection KLC Generation 2 H3.2 weatherboards are treated using the revolutionary water based micronised copper timber treatment technology called “MicroPro”. • In most applications both stainless steel and hot dip galvanised steel fixings and fasteners are safe to use with MicroPro treated exterior products. -
Page 12: Installation
Each weatherboard is single nailed so that the weatherboards can expand, contract and move independently of each other. KLC does not recommend the use of any sealant/glue being used by the painters under the lap of each board, this inhibits the natural and ongoing movement of the weatherboard. -
