Garrison is the next generation of treated finger-jointed pine, precision manufactured from Claymark’s premium radiata pine blocks. A next generation patented treatment, Tru-Core®, is used to preserve and extend the life of the wood.

Garrison is the first choice for any job that requires a superior finish. But it has more than great looks in its favour. It is an environmentally sound product, sustainably grown and precision manufactured in New Zealand to Claymark’s exacting standards.

Garrison® is a cladding product unique to our company. It has been researched and developed by us to provide our customers with the ultimate superior finish.

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.
