Does new stain require stripping?

I have a half new, half old deck that needs to be stained to look like one. The new decking was put on last summer so it is weathered and ready to be stained. The old decking has been stained for at least 10 years, sometimes with water based, sometimes with old, sometimes with a hybrid. It always seems to accept the stain without having been stripped or sanded. It is currently weathered and dry and seems ready to be stained.

I plan to use AC semi-transparent stain in either Rustic Brown or Black Walnut and will be sampling them today. I would prefer not to use semi-solid. If this stain matches the woods up enough for my liking, do I have to strip the old decking or can I just clean, brighten and stain?

You have to strip the old deck.

Okay. Not trying to be difficult, but why? So that the new stain adheres?

Am I correct with rest of process? Brighten, wash off with hose, sand if needed and stain?

You cannot apply a different brand of stain over this. It will not soak in or adhere correctly.

Use a deck stripper and pressure wash. Sand only if needed. Brighten when done.

My deck is prepped and ready to be stained. I had planned to use Armstrong Clark semi-transparent stain. It says it covers 150-200 sf/gallon. This is significantly less than most stains - does this sound right? Any idea why such small coverage? 

I used the cleaner/brightener yesterday. Is it okay if I can't stain for another week?

That is correct on coverage and all stain brands are close to that coverage amount. Try to stain within two weeks of prep.
