Drywall installers hang gypsum board (drywall/plasterboard) on wall and ceiling framing. Tapers finish drywall joints with compound and tape to create smooth surfaces. These are often separate specialties though many workers do both. Installers work with standard drywall, fire-rated boards, moisture-resistant boards, and acoustical products. Tapers use joint compound, sanding, and finishing tools to create seamless surfaces. Typical hourly rates range from $25-$60. Union drywall workers typically belong to the International Brotherhood of Painters and Allied Trades (IUPAT). Specializations include curved walls, metal stud framing, acoustic finishes, and plaster work. Modern materials include quick-setting compounds, dust-control systems, and specialty fire-rated products.
