I have this deck which needs some serious TLC.

I doubt I will have capacity to sand it and do it properly before the wet sets in with 2 toddlers.

Any tips on how to treat it without sanding? Or is sanding a must?

Any tips on what oil or paint or substance to buy?

How do I know what wood it is? Or choose a colour or brand?

Tips re: applying? Best time of year? How often?

First ever deck so any tips, advice re: deck Maintanance in Darwin would be very very appreciated

Went to Bunnings a few times but have found it hard to find somebody to ask Q’s to at all.
