David started by applying masking tape in somewhat random vaguely rock-like shapes.
Masked pillars, ready to paint.
The first coat provided some lighter highlights.
Additional layers, using different shades of gray/brown, provide rock-like detail.
David cut several different masks out of corregated cardboard.
In some areas he shot the spray gun through those.
This mask makes rocks with horizontal striations.
David removes the tape, exposing the "mortar lines".
After unmasking, the entire outside is given a protective coat of Thompson's Water Seal.
In our case, in a dimly-lit exterior haunt, this might actually be a feature: you lose a lot of detail in dim light, and exagerating details like the mortar lines helps keep them under operational lighting conditions.
We might do something to the mortar lines ... some other time.
