Thanks for the sympathetic responses, it is a nightmare. The old grout is being removed, but it is slow progress. To date only the kitchen and dining room have been done and no new grout has been put in yet. The hardener in the grout makes removal very difficult. Even diamond bits don’t hold up to it. A few tiles have been chipped in the process. At this rate it will not be finished this week and more snow is predicted for next week.
In the meantime I have been quilting on the landscape and knitting, exiled to the studio.
