- Adhesion issues: Ceramic tile adhesive may not bond well to the vinyl surface, leading to loose tiles over time.
- Subfloor stability: The vinyl may not provide a stable enough base for the ceramic tiles, potentially causing cracking or unevenness.
- Height concerns: Adding ceramic tile over existing vinyl will raise your floor height, which could cause issues with doors, baseboards, and transitions to other rooms.
- Moisture concerns: Moisture can get trapped between the layers, leading to mold or adhesive failure.
- Warranty: Many tile manufacturers void warranties if their products are installed over vinyl.
If you're set on installing ceramic tile, here are some safer approaches:
- Remove the vinyl: The best practice is to remove the vinyl flooring and install the ceramic directly on the concrete slab.
- Use an uncoupling membrane: If removal isn't feasible, consider using an uncoupling membrane (like Schluter-DITRA) over the vinyl before installing the tile. This can help with adhesion and reduce the risk of cracking.
- Consult a professional: A flooring expert can assess your specific situation and recommend the best course of action.
- Check local building codes: Some areas may have specific requirements for flooring installations.
