When looking to update the look of a room or even an entire home, one of the most significant decisions is what type of flooring to choose. While hardwood floors are beautiful and long-lasting, they may no longer fit the design aesthetic or practical needs of a homeowner. In such cases, many homeowners wonder if it is possible to install tile over hardwood floors. The answer, however, is not a straightforward one.
Before making a final decision about whether to install tile over hardwood floors, homeowners must weigh the pros and cons of such a choice. Here is a detailed overview of the process and considerations involved.
Preparing the Hardwood Floor
The first step in installing tile over hardwood is to prepare the hardwood floor. The floor must be in excellent condition, free of any damage, and level. The hardwood needs to be clean, free of dust and debris, and any wax or sealers need to be removed. Sand the floor with a heavy grit sandpaper, which will help the mortar adhere to the hardwood.
Considerations for Installing Tile Over Hardwood
The primary consideration for installing tile over hardwood is the potential for movement. Hardwood floors can expand and contract with changes in temperature and moisture levels in the surrounding air. This movement could cause the tile above it to crack, shift, or even pop off the surface.
To prevent such issues, it is essential to use an appropriate underlayment between the hardwood and the tile. A cementitious backer board or an uncoupling membrane can be used as an underlayment. The underlayment will absorb any movements of the hardwood floor without transferring it to the tile. This way, any shifting of the hardwood will be buffered by the underlayment rather than affecting the tile above it.
Another significant consideration is the height of the floor. If a homeowner chooses to install tile over hardwood, the additional thickness of the tile and underlayment will make the floor higher than it was previously. This change in height can cause difficulties when transitioning between rooms or when opening doors. Homeowners should consider whether the height difference will be too noticeable and whether they can adjust the floor height of adjoining rooms, to maintain a consistent flooring level throughout.
Choosing the Right Tile
Choosing the right tile is essential for a successful installation over hardwood floors. The tile should have a low coefficient of expansion or contraction. The tile’s coefficient of expansion reflects its ability to absorb moisture and respond to changes in temperature. By selecting tile with a low coefficient of expansion, the risk of the tile cracking will be minimized. It’s also best to choose a thicker and more robust tile that will offer more durability and stand up to daily wear and tear.
Grout and Sealer
It’s crucial to use an unsanded grout when installing tile over hardwood floors. Unsanded grout is perfect for filling gaps between tiles, and it will not scratch delicate surfaces like hardwood. Sanded grout could damage the finish on the hardwood and cause scratches over time.
After installing the tile, it’s time to seal it to prevent moisture from penetrating the grout joints. Sealing also helps keep the tile clean by preventing dirt and spills from penetrating into the porous surface of the tile. A high-quality sealer will provide a layer of protection for the surface, protecting it from damage and prolonging its life.
The Bottom Line
Installing tile over hardwood floors can be a viable option, but it requires careful planning and execution. Homeowners need to understand that movement is the biggest challenge when installing tile over hardwood floors. Thus, it is crucial to prepare the hardwood surface appropriately and use an appropriate underlayment to minimize any movement’s effect. Choosing the right tile, grout, and sealer is also essential for a successful installation over hardwood floors.
Now that you have a thorough understanding of the process involved in installing tile over hardwood floors, you can make an informed decision about whether it is the right option for your home. With the right preparation, materials, and execution, you can create a beautiful and durable tiled surface that will stand the test of time.
