ConCor Bakery: Part 2, washing brick
After doing a little research I found a couple of different techniques, the best of which I found on the NMRA website. This technique was to paint the walls a brick color, using an airbrush. Once that had dried I mixed up a batch of watered down white paint. I brushed this over the wall, covering about one third of the wall.
After allowing it to dry for about one minute I used a rag (an old T shirt) and wiped off the majority of the paint. This had the affect of removing the white paint off the bricks, leaving the white in the mortar lines. I was very pleased with the look, especially considering how quick and easy it was. Here is the picture of the results:
As you can see it is very bright, but I intend to airbrush and use chalk to complete the look.
