Hi folks. I am new to this forum. We moved into a house where the kitchen floor is Welsh slate and we were told it was sealed. It is looking a bit weary. How do I set about refreshing it? (all I've done in the last 2 years is wash it). Do I have to strip off the old sealer? Or can I just put a new sealer on top? Or is there any better alternative. Have read up on various products but am no wiser. Which ones? And which method? Thank you!
