Hi, I live a few miles inland from San Francisco, Ca. I have a twenty year old redwood deck that was never stained and have added more than double the size with new Con Heart redwood. the deck is in the shade for part of the day and full sun for part. I haven't noticed any mold but did have a little rot in the ends of some of the old boards. So, I'd like to stain the whole thing but am thinking of using a floor sander to get the old boards smoother and get down to some colored wood. I tried this method on a deck at Tahoe and it worked fabulously. Once I'm into colored old wood, what is your suggestion? I'm thinking I ought to stain the old wood now and wait to do the new wood but, if so, what colors should I use? Any advice would be greatly appreciated, and thank you for taking the time to provide this service!

PS, I'm going to try replying to this post so I can show pics of the situation.
Here's a pic of old next to new.

I would pressure wash and use a deck cleaner to remove the gray wood fibers. Sand after to smooth it down. I would stain all at once so you might want to wait for the new wood to season some before prepping the old: http://www.deckstainhelp.com/staining-a-new-deck/
