I have miles of decking at two houses. All timber when put in the Australian sun will suffer. When building our beach house we decided to go for Spotted Gum and let it grey. Why fight it? We applied Cutek, and will on a regular basis. At our main house we have lots of Merabu or Quilla. Will not grey the same, and leaches lots of red stain. Cheap, but would not use again. What ever you use, use a good quality oil that seeps deep into the wood not a traditional stain/or top finishing product.

Timber all the way!!! The look and feel of real timber under your feet cannot be matched. Depending on the size of the deck, paying a professional every few years to refinish the deck is not that costly and worth it in my opinion. I recently had to refinish a hardwood deck for a client and it was a huge area. It only cost $1200 for labour and materials and took only one day to do. the benefit of timber is that if you like the idea of changing the colour at some point, you can! This is not possible with composites. Just make sure you do your research as to the best type of timber for your needs.

Timber or composite decking also depends on what area you live in, regards the climate and where your deck will be. Merbau hardwood is an Indonesian timber that fares very well in Western Australia as the climate is hot and dry which tends to suit the Merbau. It can leech tannins, especially if wet, if not oiled straight after installation when these tannins are locked in. We laid a Spotted Gum deck for clients in Perth a year ago that needs constant oiling, every two months, to withstand the severity of the sun. Spotted Gum looks lovely but being in Perth, it is better to be covered. However Merbau hardwood decks are more stable, durable and don't tend to twist or shrink as other timbers such as Jarrah, Batu, Spotted Gum and pine may do. Merbau is a hardwood we recommend to clients in they are unsure what timber to go for. A timber deck fully exposed or beside a swimming pool will need more oil applications than one under a veranda or patio. NexGen composite is a beautiful board manufactured in the USA that comes in various colours and is secret clipped. This is maintenance free other than a wash down with warm soapy water every now and again. Trex is also an American board that is highly recommended. Millboard is a very good choice also and has a more of a natural look. This board is a bit more expensive than NexGen and Trex and looks great. Cons for composite is that it does get hot if exposed to the sun however, timber will get hot too. From experience, its also better to lay your composite decking when the boards are cool, not too hot as they expand and contract length wise. Composite is also scratch resistant but isn't scratch proof. Things to consider before having your deck installed are 1) how much maintenance am I prepared to do to upkeep my deck? 2) Is my deck in a termite or fire prone area? 3) Do I need a council permit? (if it is 500 mm off the ground in which case you'll need balustrading) 4) What look am I going for? (Modern, natural, rustic or contemporary) 5) How much money am I willing to invest? 6) What material do I like better? Whatever material you decide on, enjoy your deck. It will be a good investment for you and your family, and your property.

Sorry if this is in the wrong spot, but I couldn't work out how to post my question. We are building a beach house and my husband wants to use this cladding on the outside, (horizontal), and he wants to use vertical cladding on the inside, BUT the floors are vinyl planks which will run across the house from side to side, and there will be a deck outside which will have planks as well. I am thinking this will all be too many lines. Your image looks great. What have you planned for the interior?
