Overview
This video tutorial explains the essential steps for framing basement walls, including materials, measuring, assembly, and common mistakes, to prepare for electrical work and drywall installation.
Preparation and Materials
- Install rigid foam insulation before framing walls.
- Main framing components are the top plate, bottom plate (pressure treated), and wall studs (usually placed 16 inches on center).
- Use pressure treated wood for the bottom plate in contact with concrete; kiln dried lumber can be used for the top plate.
Measuring and Cutting
- Measure wall height from floor slab to joist in several spots; use the shortest measurement.
- Subtract 3 inches from total wall height to determine stud length to account for the plates.
- Mark 16-inch on center intervals on the plates before assembling for efficient stud placement.
Framing Techniques
- Stick framing (cutting and installing studs after raising the wall) is less efficient than assembling the wall flat on the ground.
- Crown all studs facing up before nailing.
- Use 3.5-inch nails and a framing nailer; secure two nails per connection.
- Lift the wall into place, aligning it with a pre-marked chalk line on the slab.
Anchoring and Alignment
- Secure the bottom plate to the concrete using a carbide tip drill bit and Tapcon screws, or a powder actuated tool for speed.
- Use a level to ensure the wall is plumb before anchoring the top plate to the joists.
- Shim as necessary if the wall height was cut to the shortest dimension.
Dealing with Bump-Outs and Corners
- Use furring strips and establish lines for flush drywall installation at bump-outs.
- For inside corners, use California Corners by turning one stud sideways to allow for better insulation and drywall backing.
Doors, Windows, and Closets
- Frame doors and windows after the main wall, adding king studs, jack studs, and support as needed.
- Cut out the bottom plate in door locations after framing.
- Small walls, such as for a sump closet, are framed and positioned individually.
Lessons Learned and Best Practices
- Mark all 16-inch on center placements and frame full walls on the ground before lifting to save time.
- Using long (16-foot) top and bottom plates can further streamline the process.
- Stick framing is more time-consuming and should generally be avoided unless necessary.
Decisions
- Use pressure treated lumber for bottom plates in contact with concrete.
- Frame entire walls on the ground and mark stud placement before lifting.
- Adopt California Corners for interior corners.
