Wanted advice on 8 year old deck. Every year I nuke the deck with this bleach/cleaner from Olympia. It does a great job on the mildew & dirt. Then, I hit it with a good coat of Behr's NWF clear, from HOME DEPOT.
I was thinking about sanding the deck this year, because I've been noticing the wood starting to split, and more frequent splintering.
First question: How offen, or should I even by sanding my pressure treated deck?
Second question: Should I be using a floor sander, like the ones they use for inside the house?
Finally, What grits of sand paper should I use for this job?
