How to Put Up Cement Board in a Shower

Installing cement board in a shower is a crucial step to ensure a waterproof and durable shower area. Cement board provides a smooth and stable surface for tiling, increasing the longevity and integrity of the shower. Here's a comprehensive guide on how to put up cement board in a shower:

1. Gather the Necessary Materials and Tools:

Before starting the installation process, gather the following materials and tools:

Cement board (backer board) of suitable thickness (typically 1/2 inch)
Cement board screws
A drill with a cement board bit
A saw for cutting cement board
A level
A utility knife
Safety glasses and gloves

2. Prepare the Shower Area:

Remove any existing shower fixtures, tiles, and materials. Ensure that the shower area is clean and dry before starting the installation process.

3. Measure and Cut the Cement Board:

Measure the area where you need to install the cement board. Cut the cement board to the desired size using a saw. Make sure the cuts are precise and straight.

4. Apply Adhesive to the Shower Walls:

Apply a thin layer of adhesive to the shower walls using a trowel. Follow the manufacturer's instructions for the specific adhesive you are using. Ensure that the adhesive is evenly distributed.

5. Install the Cement Board:

Press the cement board onto the adhesive-covered wall, starting from the bottom. Use a level to ensure that the cement board is installed straight and flat.

6. Secure the Cement Board with Screws:

Drive cement board screws through the cement board and into the studs or furring strips in the wall. Space the screws approximately 6-8 inches apart for a secure hold.

7. Stagger the Joints:

When installing multiple sheets of cement board, stagger the joints to prevent a continuous weak point. This will increase the overall strength and stability of the cement board installation.

8. Tape and Waterproof the Joints:

Apply a layer of self-adhesive mesh tape over the joints between the cement board sheets. Press the tape firmly into place to ensure a good bond. Apply a waterproofing membrane or liquid waterproofing compound over the entire cement board surface to create a waterproof barrier.

9. Allow the Adhesive and Waterproofing to Dry:

Allow the adhesive and waterproofing materials to dry completely before proceeding with the next step. The drying time may vary depending on the specific products used, so follow the manufacturer's instructions.

10. Install the Shower Tiles:

Once the cement board is properly installed and waterproofed, you can proceed with the installation of the shower tiles. Follow the manufacturer's instructions for the specific tile adhesive and installation method you are using.

Installing cement board in a shower requires careful planning and precise execution. By following these steps, you can achieve a secure, waterproof, and durable shower installation that will last for years.
