How to Hang Hardibacker

Hardibacker is a proprietary brand of cement board manufactured and sold by James Hardie Building Products, Inc. It is similar in appearance to drywall, but contains a water-resistant center core, making it ideal for use in bathrooms and other high-moisture locations. It also provides a sturdy base for tile installations, and is applied on walls, counters and floors before tiling the areas. Even novices can install Hardibacker, since the process requires no special tools.

Instructions

    • 1

      Measure the height of the wall on which you are hanging the Hardibacker board using a tape measure. Lay a sheet of the board on a table and measure the height to determine if it requires cutting.

    • 2

      Place a straightedge perpendicular to the board across the location where you need to cut it. Hold the straightedge down firmly and draw the blade of a carbide-tipped scoring knife along the straightedge. Set the straightedge aside and grasp the side of the board, pulling it up sharply to snap off the unneeded portion.

    • 3

      Locate all of the studs in the wall using a stud finder tool. Mark the location of each stud on the ceiling or the floor with a pencil.

    • 4

      Place the Hardibacker board up to the left edge of the wall and insert 1 5/8 corrosion-resistant roofing nails every 8 inches into the studs with a hammer.

    • 5

      Continue cutting and hanging additional boards in the same manner, pushing the edges as close as possible.

    • 6

      Spread a layer of thinset mortar into all the steams between the boards using a trowel.

    • 7

      Press 2-inch mesh tape over all seams so it sits firmly in the thinset. Cut the mesh tape off flush with the ceiling and floor using a utility knife. Apply more thinset on top of the mesh tape until you can no longer see it.

    • 8

      Wait 24 hours to allow the thinset to dry completely and then proceed with installing the tile on the wall.
