Natural stone paths need a gentler touch
York stone and sandstone paths, common on Victorian terraces across Islington, Lambeth and Greenwich, are more porous and softer than manufactured concrete flags. A standard turbo nozzle run over natural stone at driveway pressure can pit and etch the surface, leaving pale scarring that stands out worse than the algae it removed.
We use a hand lance and a lower bar pressure on any natural stone path, trading a slightly slower job for a surface that isn't visibly marked afterwards.
