If you are looking for a durable and long-lasting solution for your outdoor space, then cement board over wood deck might be the best option for you. This innovative solution can help you transform your old, worn-out deck into a beautiful and functional outdoor area that can withstand harsh weather conditions and heavy foot traffic.

What is Cement Board?

Cement board is a type of composite material that is composed of cement, sand, and fiber reinforcements. It is commonly used in construction projects as a backing material for tiles, flooring, and roofing. Cement board is known for its durability, strength, and resistance to water, fire, and insects.

Why Use Cement Board Over Wood Deck?

Traditional wood decks are prone to rotting, warping, and cracking, especially when exposed to moisture and extreme temperatures. They also require regular maintenance, such as staining, sealing, and painting, to keep them looking good. Cement board over wood deck, on the other hand, offers a range of benefits, including:


Cement board is highly resistant to moisture, rot, and insects, which makes it an ideal material for outdoor applications. It can withstand heavy foot traffic, harsh weather conditions, and even fire.

Low Maintenance

Unlike wood decks, cement board over wood deck requires minimal maintenance. It does not need to be stained, sealed, or painted, and can be easily cleaned with soap and water.


Cement board over wood deck has a longer lifespan than traditional wood decks. It can last for decades without showing signs of wear and tear, which can save you money in the long run.

How to Install Cement Board Over Wood Deck?

Installing cement board over wood deck is a relatively simple process that can be done by a DIY enthusiast or a professional contractor. Here are the basic steps:

Step 1: Prepare the Surface

Remove any furniture, plants, or debris from the deck surface. Clean the surface thoroughly with a pressure washer or a scrub brush and a cleaning solution. Allow the surface to dry completely.

Step 2: Install the Cement Board

Cut the cement board to fit the deck surface. Use a circular saw or a jigsaw with a carbide blade to make the cuts. Lay the cement board over the deck surface and secure it with galvanized screws and construction adhesive.

Step 3: Seal the Joints

Cover the joints between the cement board panels with mesh tape and thin-set mortar. Smooth out the surface with a trowel and let it dry for at least 24 hours.

Step 4: Install the Tiles

Once the cement board is dry, you can install your tiles using a thin-set mortar. Follow the manufacturer’s instructions for the tiles and grout.


Cement board over wood deck is an excellent solution for homeowners who want a durable, low-maintenance, and long-lasting outdoor space. With proper installation and maintenance, cement board can transform your old deck into a beautiful and functional area that you can enjoy for years to come.
