more up-to-date. We can completely change the look of any room, from the color to the texture. Best of all, it's so quick, you'll hardly know we were there! Tip: Knowing what you're up against
In most cases, walls are either drywall (gypsum sandwiched between layers of paper) or plaster smoothed over lath (either strips of wood or metal mesh). You can usually tell what you have by the feel (plaster is harder, colder, and smoother than drywall) or by tapping on it (drywall sounds hollow, and plaster doesn't). When in doubt, remove an outlet cover to see the exposed edges.
Drywall is more vulnerable to water damage; you must avoid overwetting it. And use care when you're scraping because drywall gouges more easily than plaster.
