Nathan installed the Z-Bar Knotty Alder Wood Interior Sliding Barn Door Slab with Hardware Kit that can be found at The Home Depot. The kit comes with all the materials required to assemble and hang the door, though Nathan choose to add additional 3/4 inch stock in this application because the wall was not plumb and the door would have hit the baseboard otherwise.

For a finish, Nathan and Stephanie stained the door using a water based stain by Minwax. Both the stain and the rags and brushes needed to apply it can be found at home centers.

Install The Track With A Ledger

Locate the track. Once the jambs are installed plumb and level, use scrap stock for guidance to mark the locations of the head and side casings. In this case, the track must be at least 1⁄4 in. above the top of the head casing.

Mark the holes. A scrap-plywood ledger holds the track while the screw holes are transferred to the wall. The ledger is the width of the head casing plus 1⁄4 in. The end is positioned so that it’s 1⁄2 in. beyond the outside edge of the side casing, which accounts for the wheel stop.

Fasten the track. After drilling the holes with a twist bit, fasten the track to the wall with the supplied hardware. Starting at the center, work toward the ends, where the L-shaped wheel stops are located.

The Final Details

Hang the door. Aided by a helper, put the heavy door on the track. Unlike swinging doors, which are partially supported by their jambs, barn doors rely solely on their hardware and its connection to the framing. It’s important to correct any weak framing before hanging heavy doors like this one.

Mount the guide. Space the bottom guide from the wall so that it aligns with the track above. One of its two mounting screws is accessible with the door fully open, and the other is accessible when the door is fully closed. This ensures that the door can be removed in the future.

Finish up with casing. Barn-style doors are cased like conventional swinging doors. Secure the inside edge of the casing with 18-ga. brads, then fasten the outside edge with

15-ga. finish nails.

How to do it

Part 1

secure header board to wall with screwdriver Step 1 Add Mounting Board Install a mounting board to the top of your doorway to help hold the weight of the barn door. Align the 1×4-inch board about an inch above the door frame, so there will be a 1/4-inch gap between the floor and the door. The mounting board should be the same length as the full sliding door track. Wherever you place it, make sure the door will have room to slide completely open and closed. This means it should extend past the doorway several inches on one side and several feet on the other (a few inches more than the door is wide).  Secure the mounting board to the wall with a power drill and interior screws. Before drilling, use a stud finder to make sure you’re drilling into the wall studs. This will ensure the strongest attachment for your door hardware.

We found this affordable option on Amazon that had everything we needed to hang the sliding barn door.  Before you install the track, you need to measure the door height. Starting at the floor, use a tape measure to record the height of the doorway, then add 1-3/4 inches. (Ours was installed 81-1/4 inches from the floor.) The track should start at least two inches off the leading edge of the doorway. Using a level and a partner, hold the track in place and mark screw holes with a pencil. Drill pilot holes with a 1/4-inch bit.  When installing the track, each screw hole should be aligned with a spacer behind the track. Then the track should be placed, followed by a flat washer and a screw. Repeat on all screw holes.  Editor’s Tip: Installing the track is a project that requires two people. We strongly discourage this project being attempted solo.

Place the first hanger at least two inches from the edge of the door. The top screw should be 1-1/2 inch from the top of the door. Mark the holes with a pencil. The same measurements should be applied to the hanger at the other end of the door.  Drill through your pencil marks with a 3/8-inch drill bit. Be sure to also install anti-jump discs to the top of the door, at least 1 inch from the edge of the door.  Mount hangers to door with nuts and bolts appropriately sized for your door’s thickness. Select where you want the door handle to go and secure with screws.  Editor’s Tip: The standard height of door handles is 36–42 inches from the floor.

Once in place, install floor guides following manufacturer’s instructions. Slide the door side to side to make sure it runs smoothly.  Editor’s Tip: If you’re using a custom door, double-check that the door track is wide enough to account for the sliding panel.
