What is Cement Board?
Cement board is a backer board that is often used in areas that require moisture resistance, especially in bathrooms and kitchens. It is composed of cement and fiberglass mesh, which makes it a sturdy and durable material. Here are some key features of cement board:
- Water-resistant: Prevents moisture damage.
- Fire-resistant: Provides a level of fire protection.
- Durable: Withstands heavy tiles and impacts.
Tools and Materials Needed
Before you start, gather the following tools and materials:
- Cement board sheets
- Cement board screws
- Drill/driver
- Tape measure
- Utility knife
- Square
- Thin-set mortar or adhesive
- Joint tape (fiberglass or mesh)
- Sealer (waterproof membrane)
Preparing the Shower Wall
Preparation is key to a successful installation. Follow these steps to prepare your shower wall:
- Remove any existing wall coverings, such as drywall or tile.
- Check for any plumbing leaks or electrical work that needs to be addressed before installation.
- Ensure that the wall studs are properly spaced (16 inches on center is standard).
- Clean the surface to ensure a good bond with the cement board.
Measuring and Cutting Cement Board
Once the wall is prepared, it’s time to measure and cut the cement board:
- Measure the height and width of the shower wall.
- Mark your measurements on the cement board sheet using a pencil.
- Use a utility knife to score the board and then snap it along the line for a clean cut.
- Make sure to cut holes for plumbing fixtures as needed.
Installing Cement Board
With the cement board cut to size, you can now install it on the wall:
- Apply thin-set mortar or adhesive to the wall studs using a trowel.
- Position the cement board against the wall, ensuring it is level and flush with the studs.
- Secure the board using cement board screws, placing them every 8 inches along the edges and every 12 inches in the field.
- Leave a 1/8-inch gap between the cement board and the floor to allow for expansion.
Installing Cement Board Around Fixtures
When installing cement board around fixtures, follow these tips:
- Cut the board to fit around plumbing fixtures, ensuring a snug fit.
- Use silicone caulk to seal gaps around fixtures to prevent water intrusion.
Sealing and Finishing
After installing the cement board, it’s essential to seal and finish the surface:
- Apply joint tape over the seams of the cement board.
- Cover the tape with thin-set mortar, smoothing it out for a seamless finish.
- Once dry, apply a waterproof membrane for added protection.
Common Mistakes to Avoid
To ensure a successful installation, avoid these common mistakes:
- Neglecting to seal seams properly, which can lead to water damage.
- Using the wrong type of screws; always use cement board screws.
- Failing to leave expansion gaps, which can cause cracking.
