Appreciation and gratitude for nature 's hard work in providing us with the luxury of wooden products, will naturally motivate one to preserve and maintain the qualities thereof. Due to the nature and characteristics of wooden products, any outdoor structure must be treated to prevent wood decay.
The principle causes of wood decay are:
- fungi
- woodborers
- termites
- weathering caused by ultraviolet radiation and moisture
All Top Decks' wooden products are treated with one or more of the following products and must be maintained by treating the wood product when necessary:
COPPER CHROME ARSENIC (CCA)
COPPER CHROME ARSENIC (CCA) compounds are heavy duty wood preservatives covering a wide biological spectrum without being subject to significant leaching. Copper is a fungicide and arsenic is an insecticide plus a back-up fungicide. Chrome acts as a fixing agent, reacting in the presence of wood cellulose to render the copper and arsenic chemicals insoluble.
CCA is applied by vacuum pressure impregnation and solution concentration can be varied according to the desired retention.
CCA treated timber is odourless and can be readily painted or stained once dry. It has a characteristic light green coloration. Where a "salts" type CCA formulation has been used, white powder occasionally forms on the surface of the wood for some weeks or months following the treatment. The powder is sodium sulphate which is quite harmless, rather being like table salt and can be hosed, scrubbed or wiped off. White powder does not form in cases where an "oxide" type CCA formulation has been used. Hot dipped galvanised or stainless steel fasteners are recommended for CCA treated timber.

We use numerous types of treatment which varies in terms of timber specie, traffic, UV exposure and location.
