Hi everyone - HELP
I have laid 17 sq m of Courtyard style floor tiles (ex Wickes) they are 400mm sq and have 4 dummy tiles on them.
The problem is that the family have walked on them before the adhesive had dried properly, therefore they now move if you stand on one edge and crack the grout. I have used ordinary grout, flexible grout and a grout made up using PVA as the mixing agent, none of which have made the slighest difference. (All the joints were scrapped out each time I did this).
I am unable to lift any of them as they have been laid (at the suggestion of Wickes) without any spacers. Does anyone know of any liquid gap filling product that might do the job.
Thanks
