When trying to mount a television to the wall, oftentimes the studs do not line up or the wall doesn't seem sturdy enough. To surmount these problems, you can use a piece of sturdy plywood to attach to the wall. Once the plywood is secure, a mount is attached to the plywood, and then the television is attached to the mount. This method is inexpensive, durable and requires very little time.
The size of the sheet of plywood you will be using will be determined by how big your television is and the type of wall you will be attaching it to. Balloon walls have no studs, and will require a whole sheet of plywood. Load-bearing walls have studs that are typically spaced 16 inches on centre. For example, a 37-inch television can be placed on a 20-inch by 34-inch sheet of plywood that is attached to three studs. Your plywood should not be less than 34 inches. Thus, it can be attached to at least three studs.
Mark the area of the wall where you would like to hang your television with your pencil. Find the studs with the stud finder and mark the location of the studs.
Position the plywood over the spots that are marked, and remark the spots on the plywood.
Screw through the plywood and into the studs. Use four screws for each stud.
Screw your television mount to the plywood and attach your TV to the mount.
