Well Gentlemen the report was thorough and after going through all the checks Bal confirmed there was nothing wrong with the product and the colour of my batch and my sample of dried grout matched the colour for this product and Bal showed via photographs a sample matching mine. As a Iso 900 company the procedure followed was correct. So what was the cause of patchy grout? the answer is I do not know.I can only guess at possibilities but cannot be certain. One thing I do know and would recommend to any person having any visual finish at all is to have samples of the finished product before committing to them.

Certainly even if the grouting was unblemished the limestone colour between manufactures can vary enormously So moving forward does any one know if as the grouting is slightly recessed about 2 mm could I re grout to this depth with a different colour,? removing the grout is out of the question.
Or could I bleach in any way the grout to lighten the colour?

Thank you

The response i thought you would get....

IMO it is probs down to too much water when washing off but as said above this particular grout has had some not so good reports on here..

So.. 2mm is too shallow to get a true grip imo.. your best bet is to recolour it.. Mapei Fuga fresca will do the job..
