TapeTech Mud Heads apply a consistent base coat of joint compound for the cleanest and most efficient installation of paper-faced corner bead. The Mud Head applies the correct amount of joint compound to maximize adhesion and reduce clean up. Attach the 16TT90 Mud Head to a Corner Applicator (35TT or 50TT) or the 14TT MudRunner® to simplify and accelerate installation of paper-faced corner bead for (internal) drywall corners.
