We finally got out driveway finished! Woohoo! soo...I'm looking for
info on coating it. What kinds of coatings are available? I'm mostly
interesting in prolonging the life of the driveway. I've seen concrete
here partially exposed to the rain, and the part exposed to the rain
eventually erodes. I'd like to prevent that if possible.

How long after pouring the concrete do I have to wait before coating
it? I've not found a lot of information on this subject, any good
sites or resources that you would recommend?
