Hi guys, been to look at a 11m2 kitchen floor yesterday and customer had laid some peel off back and stick down vinyl tiles about 4 months ago. In the sun they move so wants them replaced with slate effect tiles from homebase (already purchased) He lifted one of the tiles and the adhesive is still really sticky, hardie backer is not an option due to height of floor already. Any thoughts?

is even the 6mm board a height issue ? have a look around on here see if there is anything stopping you self levelling perhaps, not something i have come accross

Possibly SBR and then self levelling but not certain as don't know what type of glue goes on the backs of these sort of tiles. Might be worth toalking to the tile manufacturers if you can just to be sure.

best to remove glue grinder or chemical be carful with both
