How to Paint a Block Wall to Look Like a Rock Wall

When you have a block wall in your house that you feel looks unsightly, you can make the wall look more decorative by painting it. Although you could use a flat color to paint over the block wall, this could still leave the wall looking unappealing. One alternative is to paint the wall using a faux finish technique to make it look like a rock wall. Everything you need in order to create a faux rock wall can be found at any arts and crafts store.
