How to Install a Back Blocker With a Drywall Screw Gun How to Install a Back Blocker With a Drywall Screw Gun
A drywall gun, the screw type model, is essential during drywall installation. The tool's design makes the installation process a lot easier and faster than when using a cordless drill. This tool can be used to secure the drywall to a back blocker. A back blocker is a piece of wood secured at the back of two pieces of drywall so that the joint created by the two panels do not become obvious after installation.
Step 1- Prepare for Drywall Installation
Measure the entire surface area of the wall to be fitted with drywall. Purchase sufficient drywall panels to cover the entire area. Determine where the back blockers are going be positioned. Do this by dry fitting the panels onto the wall. Every butt joint not centered on a stud should be secured to a blocker. Plan the installation properly to come up with a professional finish.
Step 2 – Secure the Panels
Position the first panel onto the wall. Be sure that the panel is flush with the wall corners. Using a drywall screw gun, secure the panel to the stud and space them 6 inches from each other. On the other edge of the panel, position the back blocker at the back. If the blocker has metal legs, rotate them to fit inside the stud bay. Center the blocker at the edge of the panel.
Step 3 – Screw the Blocker to the Drywall
The screws should be spaced 6 inches apart from each other and as close as possible to the edge of the panel. To ensure the screws are evenly spaced, mark the positions correctly with a pencil and a tape measure.
To use the screw gun, load a drywall screw into the drill. Adjust the collar near the end of the drill either to the right or to the left depending on the depth of the screw required. You do not want the screw to go deep into the drywall. The screw should only leave a dimple. Therefore, do some testing on a piece of drywall first to get the hang of it before proceeding with the actual drywall installation.
When driving the screws, be careful not to hit the metal legs on the back blocker. Use a pencil to mark the location of the metal legs to avoid errors.
Step 4 – Secure the Joint and Adjacent Panel
Slide the succeeding panel and butt it lightly against the first one to cover the blocker. While holding it firmly in place, drive screws into the joint and into the center of the blocker. Afterwards, drive screws neat the edge of the adjacent panel and into the blocker. All screws should be spaced 6 inches away from each other.
This whole process is not done to bend the panels, but to anchor them to the rest of the wall. Continue with the installation in the same manner and cover the joints with mud following proper drywall installation procedures.
