CEMENT BOARD INSTALLATION
TIME REQUIRED
1-2 HRS
We recommend the use of 1/4” thick cement board as your shower backer. This is a common backer for stone and tile. Using this backer will help comply with
almost all city codes. A cement-based product like Wonderboard or Hardibacker may also be used if it meets your local codes. Some codes require a vapor
barrier to be installed as well. We recommend a water/vapor barrier of 6 mil. plastic be installed before installing the cement board. To do this, staple plastic
so that it hangs 1” above the floor. Roofing nails may be used to attach the cement board instead of screws, this prevents the plastic from wrapping around the
screws.
1. IMPORTANT: Use your cement board as an indicator of squareness. The cement board comes in
square sheets. If you see gaps or areas where the cement board is not fitting flush, fix
the problem by removing the cement board and shimming the board until it’s square and
flush. If the seams of the cement board are not flush and square, your wall panels will not
be square and flush.
2. Place the cement board against the studs and rest it on the top of the shower pan, back
flange. Attach the cement board to the studs with screws.
