A Step-by-Step Guide to Installing Large Format Tiles with Expansion Joints

Large-format tiles have gained immense popularity in the world of interior design and architecture due to their sleek appearance and ability to create a seamless and sophisticated look in any space.

However, their size can pose challenges during installation, especially when it comes to preventing cracking and ensuring long-term durability.

One crucial aspect of installing large format tiles is the incorporation of expansion joints, which help to accommodate the natural movement of the tiles and prevent potential damage.

In this article, we will guide you through the practical process of installing large format tiles with expansion joints to achieve a stunning and long-lasting result.

Gather Materials and Tools

Before commencing the installation process, ensure you have all the necessary materials and tools at hand. The basic items you will need include large format tiles, adhesive suitable for large tiles, tile spacers, a notched trowel, a rubber mallet, a level, a tile cutter or wet saw, expansion joint strips or cork, and grout.

Plan the Layout

Proper planning is essential to achieve a seamless installation. Begin by measuring the area and determining the layout of the tiles. Consider the direction and pattern of the tiles, and identify high-stress areas where expansion joints are particularly crucial, such as doorways, corners, and large open spaces.

Prepare the Surface

Ensure that the surface where the tiles will be installed is clean, dry, and level. Any irregularities can lead to tiles not adhering correctly and cause issues with the expansion joint placement. If the surface requires levelling, use a suitable self-levelling compound and allow it to dry completely before proceeding.

Apply the Adhesive

Use a notched trowel to apply the adhesive on the surface. When installing large format tiles, it is essential to use a mortar specifically designed for these tiles. Work in small sections to prevent the adhesive from drying before you lay the tiles.

Cut Tiles to Fit

Inevitably, you will encounter areas where full tiles won’t fit. Use a tile cutter or wet saw to accurately cut the tiles to the required size and shape. When installing cut tiles near walls or other obstacles, be sure to leave a small gap to accommodate the expansion joint.

Lay the Tiles

Carefully lay the large format tiles on the adhesive, starting from one corner of the room. Use tile spacers to ensure consistent and uniform spacing between the tiles. Check the level frequently to avoid any unevenness. Use a rubber mallet to gently tap the tiles into place, ensuring they are flat and level.

Integrate Expansion Joints

As you progress with the tile installation, it’s crucial to incorporate expansion joints strategically. These joints allow for movement and prevent stress-related cracks. You can use pre-made flexible expansion joint strips or cork strips.

Place the strips between the tiles at predetermined intervals based on the room’s size and layout. Be sure to follow the manufacturer’s recommendations for spacing and placement.

Allow Tiles to Set

After completing the tile installation, allow the adhesive to set as per the manufacturer’s instructions before proceeding to grouting. This step is crucial to ensure that the tiles adhere correctly and achieve maximum strength.

Grouting

Once the adhesive has set, remove the tile spacers and begin the grouting process. Select a grout colour that complements your tiles and follow the manufacturer’s instructions for mixing and application.

Fill the gaps between the tiles with grout using a rubber float, making sure to press it firmly into the spaces. An excellent example of well-graded tile grout that can be employed in the grouting of tiles is Costar Pro Joint Filler 10 & 20.

Clean and Seal

After grouting, wipe off any excess grout with a damp sponge, and allow it to dry according to the manufacturer’s recommendations.

Once the grout is fully cured, apply a suitable sealer to protect the tiles and grout from moisture and stains, enhancing their longevity.

Sometimes, the post-tiling event may play out to leave stains over the finished tile surface which later on become somewhat hard to clean off, thus a suitable tile cleaner can be employed for use in such a situation as the Costar Super Tile cleaner.

Summary

Installing large format tiles with expansion joints is a process that requires careful planning, precision, and attention to detail.

By following the steps outlined in this guide, you can achieve a flawless and durable tile installation that enhances the aesthetics of your space while minimizing the risk of cracking and damage caused by natural movement.

Remember that proper installation and the incorporation of expansion joints are crucial for maximizing the beauty and longevity of large-format tiles.
