How to Stud Walls to Garage Floors
- 1). Drill 1/4-inch holes, spaced 8 inches from each vertical member, in the bottom plate 2-by-4 board of the stud wall.
- 2). Raise the wall and maneuver the wall into the intended position with the help of an assistant. Mark the location of each hole on the floor below the wall with a piece of chalk. Lower the wall and place it out of the way.
- 3). Drill 2-inch holes at each chalk mark with an impact drill. Place a masonry anchor into each hole and tap them completely in with a hammer.
- 4). Lift and maneuver the wall into position. Place a lag bolt into the first hole and screw it into the masonry anchor with a socket and wrench.
- 5). Place a shim between the top plate and the ceiling joist on the wall above the first lag bolt. Drive a nail through the top plate and shim and into the joist from the bottom side of the top plate.
- 6). Continue down the length of the wall, insert and tightening lag bolts, then shimming the top, until the wall is completely fastened in place.
