Following on from the best decking cleaner, you’ll need the best decking treatment and oil to back it up! A quality decking treatment will penetrate deep into your wood providing excellent protection against rot and decay and not to mention leave your decking looking super healthy and new. The best decking treatment will be coat-able in a couple of hours and last a good few years before requiring sealing again. It should withstand fair wear and tare. It’s also worth using a high quality wood preservative prior to oiling too.
