TapeTech Applicator Heads apply a consistent base coat of joint compound for the cleanest and most efficient installation of paper-faced corner bead. The Applicator Head applies the correct amount of joint compound to maximise adhesion and reduce clean up. Attach the 16TT Applicator Head to a Corner Applicator (CA07TT or CA08TT) or the 14TT MudRunner to simplify and accelerate installation of paper-faced corner bead for external (outside) drywall corners.
