Why paint a faux finish? First of all, faux painting can create a beautiful look on any wall. Secondly, is not difficult. And thirdly, faux painting is MUCH less expensive than creating a wall with the actual materials. Sometimes you want more than just a boring solid color on the walls. Faux painting allows you to be creative and give any room a one-of-a-kind design. You can add a dramatic effect or just a subtle one that will give any room the character it needs.
