Can You Put Tile On Backer Board?

Yes, you can put tile directly on backer board. Backer board is a commonly used underlayment for tile installations, particularly in wet areas like bathrooms and kitchens. It provides a stable and water-resistant base for the tile to adhere to.

Types of Backer Board

There are several types of backer board available:

Cement backer board: The most common type, made from cement, sand, and fiberglass
Fiberglass backer board: Made from fiberglass mesh, coated with a resin
Gypsum backer board: Made from gypsum, water-resistant but not waterproof

Choosing Backer Board

When choosing backer board, consider the following factors:

Thickness: Available in thicknesses of 1/4", 1/2", and 5/8". 1/2" is the most common for tile installations.
Type: Cement and fiberglass backer boards are suitable for wet areas, while gypsum backer board is only suitable for dry areas.
Joint spacing: Leave 1/8" to 1/4" between backer board panels for expansion.

Installing Backer Board

Before installing backer board, ensure the subfloor is level and dry.

Mark and cut: Measure and cut the backer board to fit the space using a utility knife or circular saw.
Install: Spread thinset mortar onto the subfloor, then set the backer board in place. Tap it down with a rubber mallet to ensure a secure fit.
Screw or nail: Secure the backer board using screws or nails spaced 6-8" apart.
Tape and thinset: Apply fiberglass mesh tape to the joints between the backer board panels and cover it with a thin layer of thinset mortar.
Let dry: Allow the thinset to dry completely before tiling.

Tiling On Backer Board

Once the backer board is installed and dry, you can proceed with tiling.

Spread thinset: Apply thinset mortar onto the backer board using a notched trowel.
Set tiles: Place the tiles into the thinset, gently pressing them down to ensure adhesion.
Space tiles: Use tile spacers to maintain consistent spacing between the tiles.
Grout: Once the tiles are set, apply grout to the joints and smooth it out using a grout float.
Clean: Remove excess grout and let it dry completely before cleaning the tiles with a damp sponge.

Conclusion

Installing tile on backer board is a straightforward process that can be completed by DIYers with basic tools and skills. By following the proper steps outlined above, you can achieve a professional-looking tile installation that will last for years to come.
