it's not been sealed, afaik - there are just some imperfections in the stone where the water has puddled. the rest have dried out because it's still pretty warm
This puddling will inevitably happen with natural stone, which is why I always lay it with a fall of about 2 degrees to minimise the puddles. I would bet against that having been done on yours.
