How to Tape and Mud Drywall

Drywall taping and mudding, for many DIYers, is the most challenging part of drywall installation. The process isn't exactly art, but it can seem that way since it requires a careful hand. With a little practice, though, successful and professional-looking drywall taping and mudding can be achieved by nearly anyone.

Taping and Mudding Basics

Taping and mudding drywall happen in the middle of the drywall installation process. Taping and mudding—two events that are done at the same time—happen after the drywall has been hung and before sanding.

• Taping: Taping is the process of applying paper or mesh tape over joints between drywall sheets.
• Mudding: Mudding is the process of applying drywall joint compound, called mud, to drywall screw holes and over drywall tape.

Before You Begin

The drywall should already be installed (hung). Screws should be no more than 16 inches apart in the center (field) of drywall panels and no more than 8 inches apart on wall edges.

On ceilings, drywall screws should be a maximum of 12 inches apart on the field and no more than 7 to 8 inches apart on the edges.
