How to Put Down Concrete Board for Tile

Installing tile is a popular home improvement project that can add beauty and value to your home. One of the most important steps in tiling is properly installing concrete board. Concrete board is a cement-based backer board that provides a stable and moisture-resistant surface for tile installation. In this article, we'll guide you through the essential aspects of putting down concrete board for tile.

Materials You'll Need:

Concrete board
Thin-set mortar
Notched trowel
Screws or nails
Drill or nail gun
Level
Tape measure
Safety glasses and gloves

Step 1: Prepare the Subfloor

Before installing concrete board, make sure the subfloor is flat, level, and free of debris. Level the subfloor using self-leveling compound if necessary.

Step 2: Measure and Cut the Concrete Board

Measure the area where you'll be installing the concrete board. Cut the concrete board to size using a circular saw or tile saw. Ensure each piece of concrete board is cut cleanly and straight.

Step 3: Apply Thin-Set Mortar

Spread a thin layer of thin-set mortar onto the subfloor using a notched trowel. The notch size should be appropriate for the size and type of tile you're installing.

Step 4: Install the Concrete Board

Carefully place the first piece of concrete board onto the thin-set mortar. Use a level to ensure it's level. Screw or nail the concrete board into the subfloor using a drill or nail gun. Keep the screws or nails spaced evenly apart.

Step 5: Continue Installing the Concrete Board

Continue installing the remaining pieces of concrete board by repeating steps 3 and 4. Stagger the joints between the pieces to improve strength. Leave a small gap (approximately 1/8 inch) between each piece for expansion.

Step 6: Fill Gaps and Joints

Once all the concrete board is installed, fill any gaps or joints with thin-set mortar and use a putty knife to smooth it out. Allow the thin-set mortar to cure for 24 hours.

Step 7: Let the Concrete Board Cure

Let the concrete board cure for at least 72 hours before installing the tile. This will give the thin-set mortar enough time to fully harden and the concrete board to acclimate to the environment.

Tips:

Wear safety glasses and gloves when handling concrete board.
Use a chalk line to ensure straight cuts when cutting the concrete board.
Don't overload the notched trowel with thin-set mortar.
Check the manufacturer's instructions for the specific type of concrete board and thin-set mortar you're using.

By following these steps and tips, you can successfully install concrete board for tile. This will provide a stable and moisture-resistant surface for your tile installation, ensuring a beautiful and durable finish.
