I'm attempting to imitate this concrete wall (at least I think it's real concrete!), using acrylic paint.
For my initial attempt I was thinking of working with two grays (one slightly lighter) - First a layer of the darker color, followed with a watered down (and slightly patchy) later of the same, then a the lighter paint (maybe also watered down) where needed.
What are my chances of getting a similar effect? Do you have any tips or alternative approaches?
EDIT: I'll be painting on an already painted, solid wall (plastered brick).
