Wall tiles don't have to uphold weight the way floor tiles do, so the tile backerboards you use on walls don't have to be as strong as the tile underpayment you use on floors. However, it still has to be stable in order to foreclose cracking of the tiles, and also has to be moisture-resistant.
Cement board is the best selection for both floors and walls, though all that's commonly needful is 1/4 inch cement board on walls, as opposed to the 1/2 inch to 5/8 inch cement board you would utilize for a floor. Let us step by step discuss each and every policy to install the backer boards:

- With your electronic stud finder, you can certainly find and mark all studs behind the wall. Use your pencil in order to run the line for each stud from top to bottom.
- Spread carpenter's glue on the back of your first sheet of cement board. Press it to the wall beginning in one corner, levelling along the lowermost part of the wall. Sink the galvanized screws at the same position where you marked the studs, sinking one screw about 6 inches with every stud.
- Repeat the process for every other board, stocking them against each other and cutting them as needful to fit. Cut the backer boards by scoring the covering with the help of a razor knife and bending the piece till the time it breaks along the line. Make sure to stagger the courses so that there are no four-way intersecting points between the boards.
- Lay the pieces of mesh drywall tape on the seams and then distribute the thin-set mortar over the tape, smoothing out the mortar with the plane edge of your mortar trowel. Let the mortar dry for at least a day.
- Use a belt sander in order to moderately buff the mortared seams, which is just adequate to get them to be wholly smooth. The board is now ready for tiling.
Most citizen find it a little difficult to install backer boards on wooden sub floor. This is because the strength of wood boards isn't all the time consistent, which can lead to tile breakage. Let us discuss a few tips of installing the backer boards on the wooden floor. Screw old floorboards to join them with 2-inch screws. Place the screws no more than 3 together. Screws have good "hold-down" power in comparison to nails and will sustain in preventing the boards from weakening or cupping.
For this, you should add a layer of 1/2-inch Bc plywood over the old sub floor with the help of building adhesive and driving 1-1/4 inches screws every 6 inches. The plywood adds stiffness and stableness to the floor. With the plywood in place, install the backer board as you commonly would. In order to avoid building up the floor too high, you can use 1/4-inch thick backer board instead of 1/2-inch backer.
