It's been called many different things—sheetrock, gypsum board, wallboard, and, of course, drywall. However, all these terms refer to the same thing: a panel consisting of a gypsum core surrounded by paper backings. It's become the most popular form of wall surfacing, quickly replacing the plaster found in older homes. Why? Because it's cheaper, lighter, and easier to install. Plus, it's not as hard as plaster, so it won't crack as fast, but it's also stronger: it tends to hold objects (such as picture frames) without special hanging devices. Though it's everywhere you look, this material may still be a mystery to homeowners. Therefore, here are some basics from the very start to its final finish.
