Understanding Shower Tile Backer Board Install

Understanding Shower Tile Backer Board Installation

When it comes to remodeling a shower, one of the most important steps is installing a backer board. A backer board provides a stable and waterproof surface for your tiles, and it helps to prevent moisture from seeping into the walls and causing damage. There are a few different types of backer boards available, but the most common is cement board. Cement board is made from a mixture of Portland cement, sand, and water, and it is strong and durable. It is also waterproof and fire-resistant, making it an ideal choice for shower applications. ## Tools and Materials Before you begin installing your backer board, you will need to gather the following tools and materials: *

Backer board:

Choose a backer board that is specifically designed for shower applications. *

Thin-set mortar:

This is a type of adhesive that is used to attach the backer board to the wall. *

Screws:

Use screws that are specifically designed for cement board. *

Drill:

Use a drill with a carbide-tipped bit. *

Level:

Use a level to make sure the backer board is installed level. *

Utility knife:

Use a utility knife to score and cut the backer board. *

Tape measure:

Use a tape measure to measure the area where you will be installing the backer board. *

Safety glasses:

Wear safety glasses to protect your eyes from flying debris. *

Respirator:

Wear a respirator to protect your lungs from dust. ## Installation Instructions 1.

Prepare the Wall:

Before you install the backer board, you need to make sure the wall is clean and free of any debris. You should also make sure the wall is level. If the wall is not level, you will need to shim it out before you install the backer board. 2.

Measure and Cut the Backer Board:

Measure the area where you will be installing the backer board and cut the backer board to size. You should use a utility knife to score the backer board and then snap it along the score line. 3.

Apply Thin-Set Mortar:

Apply a thin layer of thin-set mortar to the back of the backer board. You should use a notched trowel to apply the thin-set mortar. 4.

Install the Backer Board:

Press the backer board into place on the wall. You should start at the bottom of the wall and work your way up. Make sure the backer board is level as you install it. 5.

Secure the Backer Board:

Once the backer board is in place, you need to secure it to the wall with screws. Use screws that are specifically designed for cement board. You should space the screws about 6 inches apart. 6.

Let the Thin-Set Mortar Dry:

Allow the thin-set mortar to dry completely before you proceed. This will usually take about 24 hours. 7.

Install the Tile:

Once the thin-set mortar is dry, you can install the tile. You should use a thin-set mortar to attach the tile to the backer board. ## Additional Tips * When installing the backer board, make sure to leave a gap of about 1/8 inch between the backer board and the floor. This will allow for expansion and contraction of the backer board. * If you are installing the backer board in a shower stall, you should install a waterproof membrane over the backer board. This will help to prevent moisture from seeping into the walls and causing damage. * Always wear safety glasses and a respirator when working with backer board. The dust from the backer board can be harmful to your lungs.
