Storage and Handling

Correct on-site storage of Generation 2 H3.2 products prior to installation is critical.

  • 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.
  • Store in a dry, well ventilated area.
  • Store on a flat surface 150mm above the ground, supported every metre along the length of the product.
  • Protect from the elements including direct sunlight and rain.
  • If stored outside, there must be a moisture barrier (ground sheet) under the stack.
  • 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.
  • Care should be taken when unloading KLC Generation 2 product. The profiles should be unloaded by hand or if unloaded by mechanical means, ensure that there is a minimum of 2 well-spaced load points to avoid excessive bending or sag during unloading.
  • Always carry profiles products on their edge and avoid leaning against any vertical surface to avoid any bending


Apply two coats of Premium Exterior 100% house paint. Top coat colours should have a Light Reflectance Value (LRV) of 45 or higher, as dark colours can encourage resin bleed and distortion leading to cracking and paint failure.
All cut ends, drill holes, rebates and notches must be resealed immediately with a suitably approved product. eg an Alkyd Primer End sealing can also be achieved by the application of 2 coats of brush-applied, quality Alkyd (oil based) primer which are allowed to dry between coats. When products are joined a scarf or splay join is to be used. These must face away from the prevailing weather. Alternatively, a corrosion- resistant soaker must be applied


  1. Wash all exterior surfaces using a low pressure wash system to remove dust, dirt and other contaminants.
    • Do not uses a high pressure washing system eg water blaster
    • If the washing does not remove stubborn areas of mold or dirt use a soft brush or broom and an appropriate cleaning agent to remove these deposits. Check with the paint manufacturer and read the directions on the product to apply the cleaning agent.
  2. Once the building is clean and the surfaces have been inspected for damage, wear and tear and paint coating degrade then repairs and must be undertaken immediately.
    • If the paint surface has been damaged, then:
    • Remove all damaged paint, sand back if required
    • Apply a quality primer on any bare timber
    • Once the primer has dried apply 2 top coats of a quality top coat paint.
  3. It is a general rule that timber weatherboard homes should be repainted every 10 years if the initial coating product used was of good quality, delivering a good quality coating finish. In some cases repainting may be required earlier depending on condition and exposure to harsher elements.

Health and Safety

Do not burn MicroPro® Treated Timber.
Wear a dust mask and goggles when cutting or sanding timber.
