Cement Board

Always use cement board as a sturdy underlayment when considering a tile floor or tub/shower surround in the bathroom.

“What about a tile back splash in the kitchen behind the counter top?”, you may ask.

Whatever you’re possible decor may be (particularly around water), insist that your contractor uses a sturdy cement board backerboard for outstanding protection
from moisture, insects, and other things. Wherever there may be water involved, this is what you want underneath your tile – not drywall.

Reasons To Use Cement Board

Even if you aren’t going to tile the bathroom shower wall, you should still use backer board for several reasons:

tiling bathroom wall

  • It provides a strong support for even the heaviest tile or marble.
  • Is virtually moisture proof and is not affected by water like ordinary “green board” drywall is.
  • Will not rot, warp, or swell.
  • Resistant to fire.
  • Is impervious to insects (specifically termites).

Cement board can also be used in other places that you might not think to install. Areas such as around kitchen and bath sinks, laundry rooms, closets, etc. Any room where moisture can affect things is where you want to use cement board.

It’s just a wise thing to do, and also, depending upon which part of the country (world) you live in, enforceable building code requirements using cement board may already be in place for your municipality. Check with your local plumbing
codes to make sure.

If you are going to install it yourself, you’ll find that they generally come in sheets of (2) sizes:

cement board screws

a.) 3′ x 5′ x 1/4″ ($10per sheet) – This thickness is ideal for use when tiling a floor or counter top.

b.) 3′ x 5′ x 1/2″ ($12 per sheet) – Half inch thickness is ideally suited for use as a backerboard in a
shower or tub surround.

And always use specially designed rust proof cement board screws for securing to sub-floor or framing studs.

Price per box is around $8 plus tax.
