Hi there. Has any seen an issue with tiles that de_bonded or became loose? We moved into a new build. Floor base was not powerfloated (which is better for tiling). Tiler used Larsen Primer, & Larsen flexible rapid adhesive to tile ground floor with 75x75 porcelain tiles. 6weeks later we could hear a hollow sound..from every tile. We called the builder and tiler, they removed a tile to see underneath. The adhesive was stuck to the tile, and primer to the adhesive so none to the ground...is this normal? Also there was a strong Solvent smell when we lifted the tile! Has anyone seen this? The tiler seem suprised. Would the Primer used have contributed to the issue...can it be contaminated or "go-off"?? We are now in a situation where the builder and tiler think they are not at fault, either do Larsens. But one thing for certain it is not me! Can anyone help??
