While it may seem daunting at first, installing a shower tile backer board is a manageable DIY project with the right preparation and techniques. ### Understanding Shower Tile Backer Board Shower tile backer board is a moisture-resistant material used to create a stable and watertight surface for tile installation. It typically comes in two common types: -

Cement Board:

2. Installing the Backer Board:

- Apply thin-set mortar to the shower walls using a notched trowel. - Position the backer board onto the thin-set mortar and gently press it into place. - Use a level to ensure the backer board is installed straight and flush with the shower walls. - Secure the backer board to the shower walls using cement board screws. Space the screws evenly, approximately 8-12 inches apart.

3. Seaming the Backer Board (For Cement Board Only):
