View Full Version : Brown streaks and brown spots

08-12-2007, 03:53 AM
I have had one customer say there was a couple of brown spots that showed up on the driveway a few days after sealing it, then about a week later it rained quite a bit and he said the spots disappeared. I've had another customer say that the water form the garden hose caused brown streaks in the driveway, we haven't had rain for a while so I don't know if it will clear up or if I have to go put another coat on top of the first. Why would this be happening and what's causing it?

I am using BlackMac from McAsphalt.

I would call Pro-Tech Asphalt, they sell Black mac and have been spraying with it for years. There like an hour or so from you. The # is 1-800-465-0024.
