The lava wall is not that hard just time consuming. I've tried both spray foam and block foam on other projects. For this the block foam (popcorn style) is easiest. I started by building my shelves in this case I used 2x6 in various lengths just make sure you use a heavy mount bracket. Then I glued using pl200 or similiar glue attach 1/2" foam block to the wall covering every where I wanted the lava look. This is your base. At this point using various thickness of foam start glueing to the front of the shelfs this is why you use 2x6 it gives you a good glueing surface. After covering the shelves I start filling in the depth I want accross the entire wall. keep in mind that you are going to scrub away alot of foam when shapping the wall. Use a wire brush to scrub the foam conturing it. I used different types of wire wheel in various sizes but mostly used them by hand. No power drill as it is way to easy to remove more then you want and harder to shape. After you like the shape run your electrical. I used 24 feet of l.e.d lighting along the sheves. If you leave channels in the block foam this is easy. Then paint in a semi gloss latex paint so you don't melt the foam. You could spray can if you wish but spray will melt the foam as they are all solvent based. But you may like that look who knows. Brush the paint in to all the crack and crevises be prepaired to chew through alot of brushs. Let dry and enjoy. Simplified a little but thats the general idea.

P.s. this system was shown to me by a budy. Who started the shapping and was a wealth of ideas for the project.
