Re: Proper way to prepare porch flooring for 2nd coat of Cabot's Australian Timber Oi
Your method doesn't sound too bad, however, I would wash first, then sand, sweep, apply finish, etc.

This will help prevent splotchy areas. Always sand WITH the grain of the wood. A palm sander might be a good investment for this project, you want a vibrating sander, not an oscillating one, as an oscillator will leave behind swirlies.
Washing first will minimize water seepage and speed drying time. If you sand first, you will be exposing raw wood that will soak up moisture, and it will take more than 2 days for it to dry well, unless you are in an extremely warm and dry climate. Wash first, then sand, then simply sweep or vacuum the porch with a shop vac, any remaining sanding dust will simply blend into the deck oil, it won't harm the finish.
Definitely apply two coats, being sure to follow the directions on the label as to application and drying times between coats.
