Three years ago we had tumbled marble tiles laid in the kitchen, hall and downstairs loo. They are sealed with an unpolished protector and the only maintenance they need is a quick brush and the occasional mopping.
However, once a year they need re-sealing and today is the day, as it’s sunny with a light breeze. So the floor is hoovered, mopped and once dry (hopefully soon) I’ll be on my hands and knees with a four inch fluffy roller and a paint tray full of sealer. Then it takes about six hours before I can walk on it, which means it should be done by the time Mrs HH returns from work. I always dread doing it but it’s not actually that onerous.
I much prefer the unpolished marble to shiny ceramics, though of course the latter need virtually no maintenance. I think the effort is worthwhile.
