Tiling is a timeless and durable way to enhance your home’s aesthetic, but the process can be daunting—especially if you’re dealing with the hassle of removing old tiles. The idea of skipping this step and tiling directly over existing tiles may sound too good to be true, but it’s not only possible, it can also be practical. Before diving into this shortcut, however, it’s important to understand the key factors that determine whether this approach is right for your space.
In this article, we’ll cover what you need to know before deciding to tile over tile, including when it’s safe, the benefits, and crucial considerations to ensure a successful project.
Is Tiling Over Tile Possible?
In most cases, yes, tiling over tile is feasible. However, the success of the project hinges on two main factors: the condition of the existing tiles and the structural capacity of your home to support the additional weight.
The condition of the existing tiles is perhaps the most important consideration. If the original tiles are loose or improperly adhered to the underlying surface, layering new tiles on top can create significant issues down the line. Loose tiles won’t provide a stable foundation for the new ones, and the risk of both layers coming off increases. To test the adhesion, tap each tile gently with a small piece of wood or a similar object. If the tile sounds hollow, that means it’s not properly bonded, and you should address this issue before proceeding.
For optimal results, you may want to consider using a bond-promoting adhesive. Consulting a tile expert at your local store can help you choose the right products for the job.
Why Should You Tile Over Tile?
While the thought of tiling over old tile may initially seem unconventional, there are several compelling reasons why this method can be the best choice:
Time-Saving: Removing old tile is not only a time-consuming task but also physically demanding. By opting to tile over tile, you eliminate the need to scrape, chip, and haul away the old material, which can significantly speed up your project.
Cost-Effective: Disposing of old tile can be costly, as most landfills charge based on weight. By leaving the original tile in place, you avoid these disposal fees, making the project more budget-friendly.
Eco-Friendly: Tiling over tile can reduce the amount of waste that ends up in the landfill, making it an environmentally conscious choice. You’re reusing the existing materials instead of contributing to the waste stream.
Less Labor-Intensive: The labor involved in removing tile can be grueling and messy. Tiling over the existing layer means you can bypass the physical toll and get straight to the fun part—installation.
Preserving the Substrate: Removing old tile often causes damage to the underlying substrate, which can be costly to repair. Tiling directly over the existing layer avoids this issue, keeping the original surface intact.
Things to Consider Before Tiling Over Tile
Although tiling over tile has its advantages, there are several crucial considerations to keep in mind before starting your project:
- Weight Concerns
The weight of the additional tile can put extra strain on your walls and floors. If the original tile was installed in a bathroom or on a wall, this added weight could become a concern for the structural integrity of your home. Before proceeding, it’s a good idea to consult a licensed contractor or engineer to ensure your home’s framework can support the additional load. - Height and Clearance
Adding a second layer of tile raises the height of the surface, which can interfere with the clearance of doors, appliances, and fixtures. For example, a bathroom door may no longer swing open fully, or a cabinet may no longer fit correctly. Measure your space carefully to ensure that the added height won’t create any accessibility issues or tripping hazards. - Surface Preparation
Proper surface preparation is essential for a successful tile-over-tile project. Once you’ve confirmed that your existing tile is secure and in good condition, the next step is thorough cleaning. Any dirt, grime, or soap scum left on the surface can prevent the adhesive from bonding properly. Use an all-purpose cleaner and ensure that the surface is completely dry before beginning the installation. - Adhesive Selection
Choosing the right adhesive is crucial to ensuring the success of your project. For most tile-over-tile installations, traditional thinset mortar is sufficient. However, in some cases, such as when installing heavy tiles or in wet areas, a stronger adhesive like epoxy mortar may be required. Epoxy sets quickly and can be difficult to work with, so it’s recommended for professional use or for those with advanced tiling experience. Always consult a tile expert to ensure you’re using the right adhesive for your specific tiles.
