Patio Black Spot Remover is currently the only product developed specifically to remove those hideous black spots and restore the natural stonework. Patio Black Spot Remover for Natural Stone will remove black spots from Indian Sandstone, York Stone, Limestone (including Bath and Portland), Purbeck and other natural stones. Coverage rate is based on a patio that is 3 years old. The older the stone, the more treatments required. Carry out a trial slab to determine the coverage on your stonework.

To maintain your garden stonework and stop the return of the black spots, buy and apply our Patio Black Spot Preventer annually. This will kill any black spot spores before they have the chance to germinate and turn into spots and will also remove green algae without the need to power wash!
