Quick question about a Cantina I'm building. I have the basic structure completed, and now I'm ready to start painting, however, the material I used for the walls doesn't give me the correct texture I wanted.

I was thinking about finding some very thin plaster, or the stuff you use to repair dry wall, and going over the whole structure with it, this way too I can cover up any small gaps or uneveness that have occurred.

After that though, what should paint should I use, or is this even a good idea? I'd appreciate any and all feedback or tips anyone can give me.
