In Part 1, we explained how to determine the location for a non load-bearing wall to divide a room. We also showed you how to install blocking and assemble the new wall. Now, it is time to secure the assembled wall to the ceiling and floor and create a rough opening for a door, if desired. This part of the project is not difficult but a helper should be used because the assembled wall is heavy.
You will need:
• Framing square
• Combination square
• 16d nails or 2 ½-inch wood screws
• Masonry nails or concrete anchors (if floor is concrete)
• Hand saw or jigsaw
• Circular saw
• Reciprocating saw (optional)
• Tape measure
Step 1: Have someone help you stand the new wall in place. With the framing square, square it to any walls it abuts. Plumb the wall with the level.
Step 2: Secure the wall to the floor. It the floor is concrete, use either masonry nails or concrete anchors. Otherwise, use 16d nails or 2 ½-inch wood screws.
Step 3: At the points where the top plate intersects a blocking board or stud, shim the top section of the wall. Use 16d nails or 2 ½-inch wood screws to secure the top plate.
Step 4: Before installing any sheathing or wall covering, prepare rough openings for desired doors. If a pre-hung interior door measuring 32 inches will be installed, the rough opening should measure 34 inches wide by 82 inches high. Determine the location of the door on the new wall. Use the tape measure and pencil to mark the center of this area.
Step 5: From the center mark, measure one-half of the width of the rough opening to the left and the other half to the right. For example, you will measure 17 inches to the right and left of the center for a 34-inch rough opening. Mark edges on both the right and left.
Step 6: Measure 3 inches to the right of your right-hand mark and 3 inches to the left of your left-hand mark. These will be the outside edges for the king studs in the framing of the rough opening. Install these studs so the outside face is flush with the 3-inch marks. Plumb the studs with the level.
Step 7: Cut two trimmer/jack studs to a length 1 1/2 inches shorter than the rough opening height. Nail these studs to the interior faces of your king studs.
Step 8: An opening more than 24 inches wide will have one to two wall studs between the new jack studs. Hold the level flush with the top of each jack stud. Draw a line on all studs that fall between these jack studs. Measure 1 ½ inches up from this line. Use the combination square to create a cut line on the wall studs.
Step 9: Cut the wall studs at this cut line with the hand saw or jigsaw.
Step 10: Cut a 2×4 to a length that covers the jack studs and butts up against the interior faces of your king studs. Nail it through these king studs into the 2×4 header ends.
Step 11: With the reciprocating or hand saw, cut the plate on the bottom so it is even with the interior faces of your jack studs.
Step 12: Drill and install plumping pipe and electrical wiring as necessary.
Step 13: Finish the wall with wallboard or paneling. Install the new door and door trim. Paint the area to match the existing walls and trim.
