Level 4 Drywall Taping

Master Tapers (level 4 and level 5) are Master Plasterers

Level 5 tapers are the equivalent of master plasterers as the entire surface requires compound application.

Drywallers who want work at this level will work in such environmnents as hospitals, expensive home construction/renovations and corporate office.
