How To Install Drywall Under Tongue and Groove?

Before installing drywall, ensure you have the right tools to avoid accidents.

To install drywall on the ceiling, here’s what to do:

  • Use nail protector plates to cover the wire. Determine the locations where your wiring passes through the studs and place nail guard plates there.
  • Measure the drywall and cut it. To the center of the wall studs, measure the wall. 
  • After that, score the drywall’s surface with a utility knife while using your T-square. 
  • Fold the drywall backward after that and continue cutting along the fold. 
  • When hanging drywall around a window or door, make a cutout with a drywall saw after measuring the area.
  • Buff off the drywall. Use a rasp or surform blade to make the edges even when cutting the drywall.
  • Stick the studs with glue. Apply the drywall adhesive directly to the studs. 
  • Secure the drywall with nails. Press the drywall against the studs to hold it, then secure it with nails. Aim to keep the nails away from the sheet’s edge.
  • Level the screw heads with the drywall surface.
  • Run your knife over each screw to check for evenness. Any obstruction indicates that the screw is not level with the wall, and you need to tighten or readjust the screw.
  • Cover the horizontal seams before the vertical seams using mesh drywall tape.

It is possible to install drywall on your own, but if you need more clarification, it is best to employ the help of an expert.
