Thank you for the compliment. For the brick I used a product by DuRock called Indiana Limestone. It is a cementiscious product but dries white in color like drywall compound. I used a concrete brick stencil from Butterfield that comes in a large roll and I stapled it to the wall and troweled the limestone on and then pulled the stencil a few minutes later. I watered down latex paint and and put into spray bottles and sprayed two colors on the wall at a time randomly and constantly rotating the colors that I was spraying together. I used 6-8 different colors for the brick. I used a product called versiplast tinted to a grout color and a cake decorating bag & tip for the grout.
