Joint Compound Composition

In addition to the large drywall panels, a wall system also depends on the joint compound, or mud, that covers the tape sealing the joints between panels. Because this compound dries to a finish that looks very much like gypsum, it's often assumed that joint compound is a liquified gypsum material. It is not. Instead, the composition of drywall mud includes:

• Calcium carbonate: Otherwise known as ground limestone, this is the main mineral in drywall mud. 
• Talcum: Ultra-fine talcum powder is what makes sanding drywall joints such an unpleasant chore. This ultra-fine mineral, familiar in baby powder, is used in a joint compound because its plate-shaped particles lie flat and resist cracking. Talc is the element that helps your mud sand down as smooth as glass. Between 5 percent and 15 percent of joint compound, by volume, is made up of talc.
