Okay... I had a new concrete driveway poured this past summer. Now it's winter around here and I had a little ice from compacted snow this past week and sprinkled some salt down to keep the mail man from killing himself. Anyway.. my father.. who just had a patio and sidewalk put in over the summer tells me I shouldn't put salt on new concrete for 2 years. (???) He didn't know why.. but he was told this by his concrete guy. What am I risking by putting salt down? Stains? Spaulling? I'm looking for my concrete guy's phone number to call him today but was wondering if anyone has heard this.
