Have posted for replacement porcelain floor tiles that have been discontinued without success, so wondering if it's possible to invisibly repair them? Floor was laid when house was built in 2007 on concrete rafts(?) but cracks didn't appear until around 3 years ago, which is puzzling - there aren't any cracks in external walls/doorways/skirting. Cracked tiles extend from one side of kitchen to the other and I'm hoping, probably in vain, to avoid having to have the whole floor taken up and replaced, excess of 60 mts.
Any suggestions please?
