@Dallas Joseph Dallas it takes longer to mix the wash than to apply. The whole 10 foot length took 15 minutes or so to get the color down. The thing here is the various colors are mixed together and then watered down a lot, to make a wash. This is one of the handy characteristics of drywall and casting plaster is it absorbs color nicely without being painted. The following is a forum link where I talk about mixing and applying color. painting comments Removing the last bit of paper from the drywall also roughed up the plaster surface. While a little damp it relatively easy to abrade and gouge the surface. This is where you can spend a lot of time making chips and crack lines. I got a set of cheap dental picks from Menards a while back which I use to dig out the brick lines. I destroyed my clay modeling tool (even cheaper) (spade head) in the process. I can use a hobby knife but have to go at the cut from both sides to get a "V" shaped groove.
The other thing I will do is add streaks of color here and there for variation. Similar to dry brushing but a little wetter to blend.
The column in the background is a plaster cast colored with wash using the same method. The wall next to the column is masonite coated with a thin sanded mortar mix painted on, after dry, I did the same wash method. It really helps to have texture on the surface to bring out contrast and definition.
I suppose the whole wall took a couple of hours total time. I do not want to spend a whole lot of time but I have my "standards" where I want something to look good to my eye.
