Lets Paint Weathered Walls

The Caterpillar phase of the Punk Moth scenario is rolling on again. All the buildings are now primed and waiting for the painting phase. There's a lot of surface to cover so I need to plan the whole painting process with care...

Before assailing any of my undercoated structures with paint I decided to make a test piece with the colour scheme that I had thought to use in the Punk Moth scenario. My plan is to paint most of the surfaces with dirty and worn white and coat the trims of the walls with beutifully patinated copper. The ground will have the similar tone with the bases of our gangs.

I picked up one of the extra walls and had the test piece undercoated with a nice layer of dark brown paint that I had mixed with various paints. Anxious as I was, I had to speed up the drying process with a hair drier. My wife looked at me with a hint of an amusement in her eye...

When the undercoat was dry, I applied some water here and there with a paintbrush and sprinkled table salt over the wetted areas. When the water had dried off and there was only salt left, I went outside and gave the test piece a nice layer of white paint with an airbrush. Actually my white paint was so low-quality that I had to give it not just one but three thin layers before all the areas were white. This had a dramatic impact on the salt which decided to stick on the surface even though I soaked the testpiece under warm water for over a minute. I had to help it with the paintbrush and finally got the salt off.

Now the wall had a nice weathered surface that needed to be shaded. I gave the surface a thick layer of brown wash and after it had dried, finished the effect with some minor details. Finally I painted the trim with bronze metallics and added some turquoise to make it look like patinated copper.

here's the finished test piece...

Now I just need to repeat the whole process in much larger scale...
