Did You Know?
1. Backerboard, also known as cement backerboard, was first introduced in the 1970s as a replacement for traditional plaster and wood-based wall structures.
2. The primary purpose of installing backerboard is to provide a stable and moisture-resistant surface for tile installation, preventing any potential damage and mold growth.
3. An important tip when installing backerboard is to stagger the seams between boards to minimize any weak points and ensure maximum stability.
4. While many people use screws to secure backerboard to the subfloor or wall, an alternative method is using special adhesive designed specifically for backerboard installation.
5. Backerboard is not only used in tile installations but can also be an excellent choice for other applications, such as exterior siding or as a backing for countertops in wet areas.
Tools Needed For Backer Board Installation
When it comes to installing backer board for tiling, having the right tools is crucial. Here are the essential tools you’ll need for the installation process:
-
1/4 inch trowel: The trowel is used to spread adhesive on the floor surface before placing the backer boards.
-
Electric drill: You’ll need an electric drill to secure the backer boards to the subfloor using backer board screws.
-
Backer board screws: These specially designed screws are used to attach the backer boards to the subfloor securely.
-
Chalk line: A chalk line is essential for marking the dimensions of the backer board sheets on the floor accurately.
-
Fiberglass tape or alkali-resistant tape: This tape is used to reinforce and strengthen the joints between the backer board sheets.
-
Adhesive: A suitable adhesive is necessary to bond the backer board to the floor surface.
Layout Design For Backer Board Installation
Before installing the backer board, it is crucial to plan and design the layout properly. Here are some effective steps you can follow:
-
Use a chalk line to mark the dimensions of the backer board sheets on the floor. This will serve as a guide during the installation process.
-
Make sure the backer board is evenly distributed across the floor. Avoid having four corners meeting at one point, as this can weaken the surface.
-
To enhance substrate toughness, stagger the joints between the backer board sheets. This will prevent a straight joint line that could compromise the overall strength.
-
Mark the dimensions of backer board using a chalk line
- Ensure even distribution of backer board across the floor
- Stagger joints between backer board sheets to enhance toughness
Tip: Proper planning and layout design are essential for a successful backer board installation.
The Importance Of Thin-Set Application
Once the layout design is complete, it’s time to apply the adhesive and backer board. Here’s why the proper thin-set application is crucial:
-
Thin-set is used to eliminate voids beneath the backer board and prevent any potential floor popping out. It fills any gaps or uneven surfaces.
-
Apply the adhesive to the floor using the notched side of the trowel. This creates ridges and ensures proper adhesion of the backer board.
-
Place a sheet of backer board over the adhesive, pressing and leveling it firmly onto the floor. Ensure that there are no gaps or uneven sections.
-
As you install the backer board, make sure to use thin-set in between the board and the floor to create a solid bond and prevent any future movement.
Guidelines For Screwing In Backer Board
Securing the backer board properly is crucial for the overall stability of the tiling project. To ensure proper installation, follow these guidelines:
-
Use backer board screws specifically designed for this purpose and follow the manufacturer’s recommendations for spacing.
-
Install the screws every six to eight inches along the board’s edges and fill in the field area accordingly.
-
Important: Drywall screws should never be used to hold backer board in place as they will not provide the necessary strength and durability.
-
Place the screws at least half an inch away from the edge of the backer board, but no more than 2 1/4 inches along the perimeter.
Filling And Covering Joints With Adhesive And Tape
To ensure a seamless and strong tile installation, properly filling and covering the joints between the backer board sheets is essential. Here’s how to do it:
- Fill the joints with adhesive using the flat side of the trowel. Spread the adhesive evenly and make sure it extends at least two inches on each side of the joint.
- Cover the joints with vinyl-coated fiberglass tape or alkali-resistant tape. This tape provides reinforcement and prevents cracks and movement in the future.
- Press the tape firmly into the adhesive, ensuring it adheres to the board securely.
- Remove any excess tape, trimming it neatly once it is in place.
-
It is recommended to use alkali-resistant tape as standard fiberglass tape may break down over time due to the chemicals present in the thin-sets.

Creating A Strong And Waterproof Tile Base
Cement board is a popular choice for creating a strong and waterproof tile base, particularly around bathtubs. Here’s what you need to know:
-
Cement board is a combination of a thin layer of mortar and a fiberglass mesh cloth. It is unaffected by water and can be used as a substitute for a mortar bed.
-
Before hanging the cement board, ensure that blocking and framing details are in place to provide additional support.
-
Cement boards can be heavy and challenging to cut, but even beginners can complete the installation in a day with the right tools and techniques.
By following these step-by-step guidelines for installing backerboard, you can create a solid foundation for your tile installation project. With a smooth and flat surface provided by the backer board, your tiles will be securely and beautifully installed, ensuring their longevity and aesthetics.
Frequently Asked Questions
Can I just screw down backer board?
It is not recommended to simply screw down the backer board using drywall screws. Drywall screws are not designed to hold backer board in place securely. It is important to cut all the backer board pieces before placing them on the floor. When installing screws along the perimeter, they should be installed at least ½ inch from the edge, but no more than 2 1/4 inches.
How is cement board installed?
Cement board installation begins with preparing the work area to ensure a smooth and stable surface for the boards. Once ready, the boards are cut to the desired size and shape. Thinset mortar is mixed and applied to both the work area and the back of the cement boards. The boards are then carefully laid in place and secured using screws or nails. Seams are taped to reinforce the joints and ensure a seamless surface. More thinset mortar is spread over the boards to create a uniform base for tiling. For added protection against moisture, an optional waterproof membrane can be applied. With the cement board installation complete, you are now ready to proceed with tiling.
