The question of whether epoxy can be installed over tile is a topic of debate in the industry, particularly among new installers. While it is technically possible to install epoxy over tile, it is important to consider several factors before proceeding. Firstly, proper preparation is crucial. Grinding the tile surface may cause tile cracks, and addressing the grout joints can be challenging. Shot blasting is often necessary, but it may not be readily available for smaller companies. Additionally, the grout lines are typically slightly lower than the tiles, requiring extra material to ensure they do not telegraph through the epoxy, which can increase costs significantly. Moreover, if there are any loose or unstable tiles, they can shift over time and cause issues with the epoxy application. Moisture can also be a concern. However, the most significant concern is that epoxy manufacturers typically do not provide warranties for installations over tile. This fact alone should give pause to considering epoxy over tile, as it suggests potential complications and limitations.
