We carried out restoration work on two rooms with different floors, one with clay tiles. These are rather rare local clay tiles, no longer made and hence very precious. I scrubbed the tiles, then treated them with a waterproofing solution, awaiting now a final polish and waxing. Lots of elbow grease.
The second room with Venetian mosaic was done professionally in the Spring of 2015. Here are a few image of the artisan’s work, really outstanding job.
