Before applying deck oil to new decking the decking must be allowed to weather naturally. For pine and hardwood decking such as kwila the weathering process will take 2 to 3 months. The natural sap in hardwood decking or the h3.2 timber treatment in softwood decking must dissipate to allow the decking oil to soak in, otherwise this acts as a barrier. A simple test to check if the decking is ready to apply deck oil is to sprinkle some droplets of water on to the deck, if the droplets sit on the deck surface for more than a couple minutes the decking is not ready.
All new decking both soft and hardwoods will naturally silver in about two years. If installed correctly decking should last twenty years plus without any treatment. However to keep the 'pre-silvered' colour of hardwood timber decking or change the colour of pine decking we recommend applying a deck oil that has a colour enhancer (stain). Also some hardwood decks can be returned to the natural timber colour by using a specialist decking treatment such as Cabots Deck Clean. Then, if treated every one or two years with deck oil/stain you can keep the decking near to the natural 'un-silvered' colour. All these products are readily available in DIY stores, mix the deck oil well and test an area first.
Some years back we worked on a pine deck in Titirangi West Auckland. The deck was only 10 years old however the decking was installed incorrectly for a damp shaded environment with small gaps between the boards, in this instance hardwood decking should have been installed with large gaps for ventilation. The pine decking had been water blasted so many times that the deck was left with a fur type surface that was permanently slimy and slippery. Repetitive powerful water blasting should be avoided as it breaks down molecular structure of the timber. We installed hardwood decking (more resistant to mould) instead of pine, with larger gaps between the boards (for ventilation) and recommended a yearly oil based treatment to inhibit mould growth. I visited this deck recently whilst we worked on an another project nearby and after 7 years and it sill looks great!
We are often asked how to refurbish mouldy or slippery decks. First rule; take caution using a water blaster. To get technical a powerful water blaster can break down the molecular structure of the timber fibres leaving them damaged and frayed and this then promotes future growth of mould spores. We recommend you take your time water blasting and hold the water blaster nozzle about 500 mm above the deck. Then add treatment, mould removal products are readily available (Bunnings etc), the next day apply two coats of an 'oil based' deck oil or deck oil and stain (to add colour) and re-apply every one to two years, (or before you sell), It should only take 1 to 2 hours to apply deck oil/stain for an average size deck with $80 worth of product. Allow the deck oil/stain 1 to 2 days to fully dry depending on how porous the timber decking is, how thick you apply coats and the weather. Caution: many years ago I applied two very thick coats of Wattyl Blonde (white) deck oil to our deck, the decking timber was only a year old, it took 5 days to fully dry and I had to rope off the deck for during our 'open home'.
