HM#20 The Weeping Challange
You can stain the brick with all kinds of different mortar joints. Here is a project with weeping mortar joints, but Masonry Cosmetics still only stained the brick.
When a Homeowner built an addition on to the side of his house, he quickly noticed the brick did not match the existing masonry. After researching "brick staining companies", he decided to call "Masonry Cosmetics, Inc." By staining some bricks white and staining other bricks gray, they now have a seamlessly blended stained brick home.
