There are times with a project this big, that it really starts to feel like it’s sitting on my head and crushing it. This is one of those times.
I had hoped to be a lot farther along on the depot by now, but there’s been too many other things going on and even when I do get to work on it, it just seems to take forever. But anyway, I finally started making some progress on painting the “stone” walls of the depot. I began by giving all the walls a coat of thinned, sandstone-colored house paint:

Next I brushed on a dark concrete color. Before it dried I wiped it off with a paper towel, being careful to leave as much paint as possible in the mortar lines. This has to be done one small area at a time, or else the paint will dry before you can wipe it off:

The walls are supposed to look like a very light sandstone, similar to this:

So I had to go over each stone with another coat of sandstone paint, using a fine brush. I mixed in a small amount of white to lighten it slightly, and varied the mix so that the stones aren’t all exactly the same shade:



Next I applied thin washes of various shades of rust and brown. To finish it off, I lightly dry-brushed the whole face of the wall with a mix of white and sandstone. I still need to go in with an extra fine brush to touch up some of the mortar lines, but I’ll do that later:


That’s one wall done, and only about 37 quintillion more stones to paint. Or so it seems. 
I did get started on the next portion:
