Ever since I was little my mother has been plotting a makeover for the giant floor to ceiling brick fireplace in their living room. She doesn't want to paint it or cover it up. So when I came across this interesting staining technique it seemed like a great alternative. I know many deal with the same issue and this might be a great alternative for you as well!
She uses the brush to paint the tops of the bricks so as to not stain the mortar between them. The result toned done a crazy brick wall into something much more sophisticated. It could be a great way to "grey down" some bricks for a more modern look, turn them a little more traditional red or even go with a whole new color all together.
