How to Put Tile on Deck Versus Decking?

/by

When considering enhancing your outdoor living space, tiling your deck or decking can offer a stylish and durable solution. However, the installation process for tiles differs significantly between traditional wooden decking and a concrete or composite deck. This guide provides a comprehensive overview of how to successfully put tile on both types of surfaces, ensuring a long-lasting and visually appealing result.

Understanding the Differences: Deck vs. Decking

Before delving into the installation process, it’s important to understand the distinctions between a deck and decking:

  • Deck: Generally refers to a platform or surface structure, often made of wood, that is elevated from the ground. Decks are typically found in outdoor spaces such as patios and gardens.
  • Decking: Refers to the material used to construct the deck surface. This can include wood, composite materials, or even concrete.

Preparing to Tile a Wooden Deck

1. Inspect and Prepare the Deck Surface

Before tiling, ensure that the wooden deck is in good condition:

  • Check for Damage: Inspect the deck for any loose or damaged boards. Replace or repair any issues to provide a stable base for the tiles.
  • Clean the Surface: Thoroughly clean the deck to remove dirt, debris, and old sealants. A pressure washer can be effective for this task.

2. Apply a Waterproofing Membrane

Wood is susceptible to moisture, which can damage tiles over time. To protect your investment:

  • Choose a Quality Membrane: Select a waterproofing membrane designed for use over wooden surfaces. This membrane will help prevent moisture from reaching the tiles and causing damage.
  • Installation: Follow the manufacturer’s instructions to apply the membrane, ensuring complete coverage of the wooden deck surface.

3. Install a Cement Backer Board

A cement backer board provides a stable and moisture-resistant surface for tiling:

  • Cut and Fit: Measure and cut the backer board to fit your deck. Secure it to the wooden deck using screws, ensuring that all joints are properly covered with tape and thin-set mortar.
  • Level the Surface: Ensure the backer board is level to avoid uneven tile placement.

4. Lay the Tile

With the surface prepared, you can now lay the tile:

  • Apply Thin-Set Mortar: Use a notched trowel to spread a layer of thin-set mortar over the backer board. Work in small sections to prevent the mortar from drying out.
  • Place the Tiles: Press the tiles into the mortar, ensuring even spacing using tile spacers. Check for levelness and adjust as necessary.
  • Grout and Seal: Once the mortar has cured, apply grout between the tiles. Allow the grout to set, then seal the tiles and grout to protect against moisture.

Preparing to Tile a Concrete or Composite Deck

1. Prepare the Deck Surface

Concrete and composite decks require different preparation compared to wood:

  • Clean the Surface: Remove any dirt, oil, or stains from the concrete or composite surface. A thorough cleaning ensures proper adhesion of the tile.
  • Repair Cracks: Fill any cracks or imperfections in the concrete with a suitable patching compound.

2. Apply a Primer or Bonding Agent

To improve tile adhesion:

  • Choose the Right Primer: For concrete surfaces, use a concrete primer or bonding agent. This helps the thin-set mortar adhere better to the deck.
  • Apply Evenly: Follow the manufacturer’s instructions for application, ensuring complete coverage.

3. Lay the Tile

The process for laying tiles on concrete or composite decking is similar to that for wood:

  • Spread Thin-Set Mortar: Apply thin-set mortar using a notched trowel, working in manageable sections.
  • Place the Tiles: Position the tiles into the mortar, using spacers to maintain uniform gaps. Check for levelness and adjust as needed.
  • Grout and Seal: After the mortar has set, apply grout between the tiles. Once the grout is dry, seal the tiles and grout to enhance durability.

Tips for Successful Tile Installation

  • Temperature and Humidity: Ensure the weather conditions are suitable for tiling. Extreme temperatures or high humidity can affect the curing of mortar and grout.
  • Tile Size and Pattern: Consider the size and pattern of the tiles to match your deck’s design. Larger tiles can reduce grout lines but may be harder to handle.
  • Regular Maintenance: Keep the tiled surface clean and inspect it regularly for any signs of damage or wear.

Conclusion

Tiling a deck or decking can transform your outdoor space, providing both beauty and functionality. By understanding the differences between wooden and concrete/composite surfaces and following the appropriate preparation and installation steps, you can achieve a professional and durable result.
