The wall finishes you loved five years ago seem a little stale now. Even though the walls have held up and don't need repainting, the look seems dated. Either that or your do-it-yourself gene wants to express itself again with something completely different. Go ahead. Splash some paint on those walls. Better yet, try a new finish to add warmth, depth, and sophistication to any room.
Decorative techniques
No matter what the technique, if you don't love the finished product, simply paint over it and start again. Before utilizing a specialty paint technique on the walls in a home you plan to sell, chat with your local real estate professional to see if it's the right choice for your home.
