Drywall Contractors Key Terms

Understand the terminology associated with drywall contractors

Drywall has come a long way since the days of lath boards and plaster. Today, drywall often comes in the form of paper-wrapped gypsum board. This new and improved form simplifies the installation process. Drywall is typically used to finish off walls and ceilings before painting. Before hiring a drywall contractor, or attempting to do the job yourself, you should become familiar with some basic terminology.

Chalk line

Chalk lines are used to produce a fast and simple straight line for any drywall project. Chalk comes in several colors. Blue is recommended for more general uses while red is most often used for long-lasting jobs that will be exposed to the elements temporarily. White works best on inside walls because it is easy to remove.

Drywall primer

This term refers to a paint material expressly created to fill pores. Primer balances the difference in suction that connects the gypsum board's surface paper. These paints smooth drywall surfaces and prime them for painting.

Greenboard

Greenboard is a water resistant drywall that possesses the same gypsum core as other types of drywall, but it is covered in a thicker, wax coated paper. The wax coating aids in controlling moisture absorption. Greenboard is recommended for humid areas, but not wet areas, since it is not waterproof.

Drywall lift

Drywall lifts are designed to make it easier to install drywall in those hard-to-get-to places, such as a ceiling. This large platform allows drywall contractors to lay the sheet flat and then winch it up to the desired location. The lift secures the drywall until it can be put in place.

Keyhole saw

Drywall contractors use keyhole or compass saws to make a cutout in drywall, such as those for electrical boxes or pipe. These saws have a single handle that can accommodate a variety of small, pointed blades that are fixed or retractable.

Corner bead

Corner beads are used to keep the outer corners of the drywall from becoming damaged and to create a smooth seam. They are hung after the drywall has been installed.
