Tiling is a popular home improvement project that can add both value and beauty to any room in your house. But before you embark on this adventure, there’s an important question that needs an answer: Can you tile over tile?
The answer isn't always straightforward — it depends on the type of tile being used, as well as the condition of the underlying floor. In this blog post, we’ll explore all the factors involved in laying tile over tile so that you can determine if it’s something you should attempt or not.
We'll also discuss how to properly prepare surfaces for new tiles so that they last long-term. So let's get started!
Tile Installation Process
The process of laying tile over old tiles is not as straightforward as it may seem. Although it is similar to the same process of installing regular tile. It requires careful consideration and preparation to ensure that the new tiles will be correctly installed and last for a long time.
Before beginning, you must consider the type of tile being used, the condition of the underlying surface, whether there's an uneven surface or cracked tiles, and what steps need to be taken to properly prepare surfaces for new tiles.
Prep Work
Proper preparation of the surface is essential to ensure that new tiles will be correctly installed and last long-term. Assess the condition of both the original tile and the underlying surface before beginning any work.
This includes cleaning your tileand removing any loose or damaged tiles on the floor and making sure there is no hollow sound so that the damaged tile doesn’t interfere with the installation process.
Additionally, make sure that all surfaces are leveled and free from debris before you start to lay tile.
Finally, check for moisture levels beneath your subfloor as high moisture or trapped water can cause problems down the line such as mold growth or water seepage through cracks between tiles.
Step By Step Installation
- After prepping, by cleaning and sanding down the surfaces, use a level and tape measure to ensure that the subfloor is even before beginning tiling over existing tile floors so there are no loose tiles.
- After you secure loose tiles you can apply a thin layer or two layers of tile adhesive or mortar to the back of each tile, then place them on the floor in a pattern. Making sure to firmly press down on the trowel as you go to ensure that the adhesive is solidly bonded with the existing tile surface, through the drying and adhesion process.
- When all of the tile is laid out, use spacers between them to ensure uniformity and even grout lines, so that there are no strangely placed tiles. Pro-tip is drawing straight lines along the previous floor to help keep everything straight.
- Once all of the tiles are in place whether on the floors or walls, press down firmly, it may take some extra effort with a rubber or wood mallet or roller to ensure that they are properly bonded.
- Allow 24 hours for the adhesive/mortar to leave the surface dry completely before grouting.
- Mix grout according to the manufacturer’s instructions and apply it into gaps between tiles using a floating tool.
- Wipe off excess grout from tile surfaces with a damp sponge after 20 minutes.
- Buff the grout joints with a dry cloth and seal the tiles to protect against staining or water damage.
- Allow 48 hours for the grout to cure completely before walking on the new floor.
