Hardwood Deck - how to stop going grey..?

[Trikster]

Put down a nice Balau hardwood deck about 2 years ago, didn't treat it so has gone grey.

Have found a great product to bring back the natural colour (PrepDeck) but am unsure what's best to then treat the deck with to stop, or at least slow down, the greying process... any suggestions??

Plenty of wood oil, a good quality Danish oil applied at regular intervals.

Personally, and this is something a lot of people will say 'No' to, I varnished mine.

No, never varnish, for once you do that you are sealing the timber, which creates much more work in preparing the timber in later years for colouring/staining.
