    Default Untreated Spotted Gum Deck

    Hi All,

    I'll be putting down spotted gum decking around a saltwater chlorinated pool, and considering to leave it totally untreated and let it age naturally to a nice silver/grey.

    I got a couple of off cuts from the local timber yard a few months ago, and have left them in the backyard exposed to the elements to see how they fair, and so far so good. In about 3-4 months they've started to grey, no cupping, and obviously roughened up, but no real splinters as such. I washed one length with napisan before laying out to see if that sped up the aging process.

    Whilst they look great now, and it's the look we're going for, i'm wandering how they will hold up over 5-10 years.

    Has anyone done this with spotted gum over the longer term?

    Note, all structural timber under the deck with be TP.

    The much talked about sealer/oil here is cutec - that's used on architectural places on timber cladding, but without a tint to let the timber grey, then occasionally reapply, so you keep the grey look but also protect the timber and stop it from splintering etc

    I have heard of a new Feast Watson product coming out, specifically for letting the deck go grey but keeping it protected, it's a clear coating, not on their website yet.

    If you are going to leave the timber go grey, why go to the trouble and expense of treating it? With a clear, this breaks down so quickly anyway that there is next to no advantage in using it. Spotted gum is a dense timber and will probably outlast us. We treated a pine deck that had had no attention to it for 10 years and whilst it was dry and rough, it wasn't as bad as originally thought. Many of the houses in Europe are left to grey off with no treatment and whilst they do not have the hot Aussie sun, they do have the minus temperatures and snow.

    The aim of clear oils is to protect the timber from water damage, not the sun/UV.

    Below is a Spotted Gum deck we extended some tima ago, the greyed off section was only 15 months old (never coated), IMO I didn't like it, it was quite rough to touch and would require sanding to get anything decent from it again.
