Tile-over-tile installations are gaining popularity in commercial and residential renovations for their speed and cost savings. But while this method eliminates the need to rip out old flooring, it introduces new challenges for adhesive performance. The success of these projects depends on selecting the right adhesive and application method.
At Buildix ERP, we help contractors and facility managers navigate adhesive selection for tile-over-tile projects, ensuring durable, flawless results.
Why Adhesive Selection Matters in Tile Over Tile
Existing tile substrates are often non-porous, making it harder for standard adhesives to bond effectively. Poor selection can lead to:
✅ Bond failure and tile delamination
✅ Hollow sounds and movement underfoot
✅ Moisture entrapment between layers
