The dry tape banjo gets its name from having the roll of drywall tape separated from the wet drywall compound – keeping the roll dry, and only applies mud to the tape lead. This Goldblatt style banjo is the most popular design among drywall contractors.
Why do you tape drywall?
Drywall tape and coats of drywall compound are applied to reinforce joints and conceal screws and nails. When taping and mudding are done correctly, the wall is flat and smooth and the seams underneath are hard to see.
