Garrison Bevelback Weatherboard

Garrison Bevelback Weatherboards are made from sustainably grown, finger-jointed pine, which is treated to protect against decay, and comes sealed and pre-painted with two coats of acrylic.

Treated with Tru-Core, a diffusion based system which uses waterborne carriers to give 100% penetration of sapwood and heartwood. Tru-Core also uses five different biocides to give widespread protection against fungal decay and termite attack.

Each board comes factory coated with polymer based sealer which resists water uptake and provides a coating of 100% solids for full protection; and finished with two coats of 100% acrylic undercoat giving a consistent 50 microns of dry film build. 

Bevelback weatherboard sizes:

  • 135x18mm
  • 142x18mm

  • 187x18mm

The product range includes weatherboards, eave mouldings, and box corner finishing systems.
