Installing Cement Backerboard


You may be tempted to rush ahead and get to the fun part - laying the tiles. But resist the urge. Unless you prepare the surface under the tiles properly, you'll end up having to retile a lot sooner than you want.

Tiles need a smooth, flat, rigid surface to sit on. Plywood is sometimes used, but cement backerboard is generally considered a better choice. Backerboard is essentially a thin layer of concrete with fiberglass mesh on both sides. It was designed specifically as a setting surface for tile.

Backerboard comes in a range of sizes: 3- by 5-foot sheets are most common for floors. Over a 5/8-inch subfloor, use 1/2-inch-thick sheets.

WHAT YOU'LL NEED

SKILL SCALE
Medium

TIME REQUIRED
You can install cement backerboard in a 5x7-foot bathroom in 2 hours.

TOOLS
1/4-inch trowel
Electric drill

MATERIALS
Backerboard
Screws
2" vinyl-coated fiberglass tape
Adhesive
Chalk line

Cement BackerboardSnap a grid of chalk lines on the floor to mark the dimensions of the sheets. Plan so that joints in the backerboard won’t line up with joints in the subfloor. With the smooth side of a ¼-inch notched trowel, spread enough adhesive for one sheet. Ridge the adhesive with the notched side of the trowel.

 

 

Cement BackerboardWhile the adhesive is still wet, place a sheet of backerboard into it. Leave a ¼-inch gap between the backerboard and the wall and a 1/8-inch gap between the backerboard sheets. Position the sheets so that you don’t have four corners meeting.

 

 

 

Cement BackerboardAfter you've positioned each sheet, drive backerboard screws into it every 8 inches. Around the perimeter, position the screws at least 1/2 inch, but no more than 2 inches from the edge.

 

 

 

 

Cement BackerboardWith a margin trowel or the flat side of your notched trowel, fill the joints with adhesive, smoothing it so it extends about 1 1/2 inches on each side of the joint. The extra adhesive makes it easier to bed the tape.

 

 

 

Cement BackerboardCover the adhesive-filled joints with 2-inch vinyl-coated fiberglass tape, pushing it firmly into the adhesive. You can cut the tape to length with the thin side of your trowel. When the tape is embedded, scrape off any excess adhesive from both sides.

 

 

 

Cement BackerboardCover each length of tape with a thin layer of adhesive. Spread the adhesive with the flat side of your trowel and feather the edges. You want the transition from board to board to be as smooth as possible.
