Timber Preservation
In-Situ Timber Preservatives
Kardon Marketing Services proudly offers Arch Wood Protection Pty Ltd.’s range of in-situ preservative chemicals, CN (Copper Napthenate) Emulsion and CN Oil.
Constructed by Hollis Marine Services Pty Ltd in March 2004. The deck was coated with CN (Copper Napthenate) Emulsion.
In-situ Timber Preservation
An essential part of maximising the service performance of timber and timber structures is that in-situ preservative treatment be carried out to minimise biological degradation. Pressure treated timber is protected against this form of degrade. However, every time treated timber is cut, exposing internal untreated sections, in-situ application of preservative is essential. We are pleased to offer the following range of products, which we recommend for protection in-situ of timber structures.
CN Emulsion
CN Timber Emulsion is a barrier to fungal spore attack and consequent decay formation. The emulsion is a paste about the same consistency as chassis grease. The product is used on timber end grain, around posts at the ground line (and 300 mm below), at the interfaces of joints before assembly and on the top faces of girders and bearers. It is available only in 20 kg and 200kg pails.
CN Timber Oil
CN Timber Oil is employed on deck surfaces and for painting of fences and any exposed timbers. The product offers increased water repellency, which means that moisture uptake and loss due to weather conditions is reduced, with resultant reduction in swelling and shrinking which mechanically damages wood. Application is by paint brush, roller or squeegee. It has even been “airless” sprayed with appropriate face masks etc. The oil soaking into the wood further takes the preservative (copper naphthenate) deep into the wood to combat decay. It is an oil, and thus time must be allowed for the material to soak into the wood. CN Oilis supplied in 20 litre drums or 200 litre drums. Insecticides, such as “Vacsol T”, may be dispersed in this oil to add insect repellency.
