Can I use Aussie Clear on treated pine?
Yes, but the trend is to use the Aussie Clear Walnut finish because it gives the pine an expensive woody finish. Order a sample can and see for yourself.
How do I prepare my deck/timber for re-application?
Clean the deck with Grey Deck Cleaner and a deck preparation scrubbing brush like the one that comes in the UniPro decking kit. Use of a pressure cleaner is recommended but use the car cleaning nozzle. Pressure cleansers can erode timber with the standard high-pressure jet nozzle. If the deck looks terrific when wet then that's more or less the result you'll get after a couple of coats of oil.

Yes. Any outdoor situation. Also can be used indoors.
Do I have to sand back the timber prior to re-application for best results?
Not if you are re-applying Aussie Clear. Sanding is only recommended if your timber is really bad, or you’re switching from a water based film-forming product like Cabot Aquadeck.
Do you have any wood preservatives for timber that has been submerged in a flood?
Yes, No Rot Gel can be applied to the damp timber, infact the gel works best on a damp timber!
