Q: Tim, I have a big decision to make and need your help. I love the look of colored brick for paving, including my driveway, sidewalks and patio. The issue is I’ve started to pay attention to older installations of colored concrete paving brick and many look faded. Why is that happening? Some look horrible, especially at a restaurant I patronize. I don’t want my investment to look faded in a few years. Do I have alternatives, and is there a way to restore the color of faded concrete brick pavers? —Mary Chris F., Tampa, Fla.
