Drywalling is putting in drywall panels on the interior of a home. A drywalling professional sections off dry wall panels according to the required design. He then installs them on the interior wall of residential or commercial buildings.
A professional in drywalling is familiar with the best practices in the industry. These include staggering the butt joints of the drywall, not pairing butt edges with bound edges, keeping the studs at right angles to the drywall panels and hanging the drywall ceiling first.
Important aspects of drywalling
Types of joints and their importance
As a drywaller you’re expected to know your joints. The sheet of drywall has a tapered joint and a butt joint.
The tapered joint slopes slightly at the end. You’ll take less time in finishing two tapered joints that you’ve put together. In order to do finish this you’ll put on a tape joint, a fill coat and a finish coat. Then you’re done.
However when finishing two butt joints put together, the steps are more. This involves applying mud and tape and then mud several times.
Knowledge of screws
Another important thing to master is the knowledge of screws. You must know the length for your particular drywall sheets and also the thread. For your residential panels the rough threaded screw works perfectly.
When you use a fine threaded screw on your panels you’ll find that it becomes loose. The fine threads aren’t built to grip wood tightly. They’re actually designed for metal panels.
To calculate the length of the screw, multiply the thickness of the drywall by 1.5. Then add the thickness to this number. That’s the length of screw that you need to buy.
Correct order of drywalling
This is basically putting the ceiling boards in before the walls. The reason for this is so that you’re able to seal gaps properly. When the ceiling boards are in, you can put in the wall panels right against them leaving no gaps.
Also make sure you know where the ceiling fixtures are before beginning drywalling. Remove anything that is in the way such as light fixtures and smoke alarms.
Put in your drywall opposite to the direction of the strapping. Your strapping should be put in every 16 inches on the ceiling.
Tools used in drywalling
Some of the tools that you’ll use in drywalling include:
- Knife, drywall saw or cutting bit
- Tape measure
- Drill bit
- Drywall tape
Drywalling is can be learned, but just like painting, with training and practice.
