How to Install Cement Board


Cement board is a sturdy product made from combining wood with cement filler. It provides a strong enough product to pass hurricane codes, according to North Carolina State University. It is often referred to as Hardie board, even when it is not manufactured by the Hardie company. Cement board comes in various thicknesses and widths.

Things You'll Need

  • Cement board
  • Screws or nails
  • Hammer or drill with screwdriver bit
  • Rotary saw
  • Stud finder
  • Sandpaper
  • Paint
  • Line the first piece of cement board up with the outer edge and bottom of the wall. Depending on the size of the board and your strength, you might need a helper to line it up and hold it in place.

  • Nail or screw the cement board to the studs of the wall. Place a nail or screw an inch from the edge of the cement board. Place a nail or screw at the bottom of the cement board, then one in the middle. Repeat for every second stud.

  • Repeat the process until the bottom portion of the wall is covered, cutting the last board to fit, using the rotary saw. Line the second row of cement board on top of the first row. If the cement board is four feet high and the wall is 8 feet high, the second row is the last row, and there is no need to cut to fit for height. You might need the stud finder if you cannot see the studs for the second row, and if needed for subsequent rows. Repeat the process for all four walls.

  • Caulk the seams of the cement board if you are not going to fill the inside with insulation (for a shed, for example). Sand the caulked seams down, so they are smooth.

  • Paint the cement board to help protect it from the elements. While it is a strong product, it is still made from wood and could warp after being exposed to water for a long time.
