A Step-By-Step Guide To Installing Drywall on Metal Stud Walls
Installing drywall on metal stud walls can be much simpler than other types of wall assembly because of the increased stability the combination of metal and drywall provides. It’s important to take the right measurements, use the correct tools and materials and follow the correct installation process to ensure a successful installation.
Before you start, make sure you take measurements of the area you’re covering and that you purchase enough drywall. A mesh-backed sheet that’s at least 5/8 inch in thickness should be used for drywall installations on metal stud walls. You’ll also need special drywall screws and a drywall saw for any holes or openings which are irregular – like arches.
Once the materials and supplies have been gathered, it’s time to start cutting and installing the drywall. Using a drywall knife or saw, cut the drywall to required size and ensure the pieces fit together correctly. If there are any irregular openings such as arches, use a drywall saw to cut the pieces accurately. Place the sheet against the surface and lightly tap it with a flat wood block to create a dimple on the back. Then, use the knife to cut an accurate hole.
Once all the pieces are cut, it’s time to attach the drywall to the metal studs. Measure the vertical studs to ensure that they are at valid centers (16 or 24 inches) and mark the centerline on each stud with a pencil.
Using a drywall screw dimpler that is loaded with a spring, countersink the screws to the same depth before ratcheting any screw bits. When installing the screws, it’s best to start in the center of each stud and install the screws at an approximate 8-inch center. Try to install the screws closer to any edges that will later be trimmed – these screw heads will be covered by the trim or baseboard once the drywall is installed.
Once all the screws have been installed, it’s time to apply the drywall tape and mud. Make sure to use conventional drywall tape for a strong and lasting bond instead of perforated or fibre tape. Dampen the tape lightly with water and press it over the joints where you have applied the mud. Use a knife to apply enough mud to each joint and use a smooth motion when swiping it, wiping away any bubbles. It’s important to note that the mud (especially pink mud) dries fast and it’s best to allow the joints to dry thoroughly before applying the next coat.
Once the final coat of mud has dried, use a pole sander with drywall sandpaper to smooth the joints and make sure you don’t sand off the top layer of the drywall. Finishing a drywall installation on metal stud walls is much easier if you have the right materials, tools and processes. Following these step-by-step instructions will help you install drywall on metal stud walls and ensure a tidy, professional-looking finish.
