Yes, making new concrete look aged. Hear it on the phone tonight , from the story teller I posted about yesterday, Jeff Carroll. He said something like, “Tell your readers to use buttermilk to age concrete, they’ll enjoy learning about it.”
Jeff and I have been friends for 20 years, but buttermilk? He said he once built a concrete and stone fence, but the concrete looked too new. He got buttermilk and put it in an old hand pump sprayer. Not many weeks later the lichen and algae started growing all over the fence and aged the new concrete nicely.
If you’re interested, perhaps wanting to age a new yard statue, birdbath or any decorative concrete item, there are several easy-to-find articles about the process. This one, at eHow, uses buttermilk, yogurt, and moss: http://www.ehow.com/how_6143908_make-concrete-look-aged.html
Even Martha Stewart mentions the technique: http://www.marthastewart.com/268962/hypertufa-pots
