We are trying to match a brick color on our 35 year old house. We purchased some new bricks, but the color is not a good match. We have been told there is a way to stain bricks. In our case, we would just like to make one side of each brick a slightly different color (darker and more peach). Can anyone tell us how to stain these bricks and what to use to stain them? They are still stacked in our driveway. Thank you.
