No, joint compound isn’t for those aching and creaking bones of yours. It’s for the structure of your home’s walls and ceilings—drywall. This white pasty substance comes in a tub and is used to smooth over the screws, hanging tape, holes and other blemishes on the surface of the wall to create an even canvas for wall texture and paint. There are two varieties available: “mix-it-yourself” and “ready-mix,” which is easier to use than the former because it doesn’t dry as quickly.
