Light Organic Solvent Preservatives are used for structures subject to moist environments where timber is likely to experience fungal decay. LOSP treated timber can be painted once the treatment has dried. It is recommended that all treated timber is painted or stained. The treatment is not corrosive to metals. LOSP is suitable for applications such as joinery, where dimensional-stability is important.
Ammoniacal Copper Quaternary is vaunted for its greater safety of storage and application than CCA, yet with similar performance ability. Ammoniacal Copper Quaternary (Type B) wood preservative is formulated with copper oxide and the Quaternary Ammonium compound, didecyldimethyl-ammoniumchloride.

All standard timber components are factory stained with Cutek CD50 oil based stain in New Bronze Tone. Others stain colours are available upon request. Timber components can also be supplied with a water based paint finish. We apply two coats of quality Wattyl paint in our factory prior to despatch. Due to the likelihood of damage during transport and installation, we supply a small quantity of paint for touch up on site.

Powder coated, hot-dip galvanised steel is considered an unsuitable finish for highly corrosive environments. In these environments we strongly recommend the use of timber (either pine or hardwood) and stainless steel hardware. If this is not possible all hot-dip galvanised steel surfaces should at least be finished with a high quality two pack epoxy paint system, and subject to a rigorous maintenance schedule. Failure to do this in highly corrosive marine environments may void the Landmark Products Ltd Structural Integrity Warranty
