Sandstone is sedimentary; it cures in layers and splits in layers. The vibration caused by pressure washing causes these layers to delaminate, resulting in destroying the surface and breaking the stone.
Patio Black Spot Remover gently removes patio black spots, completely restores the colour to garden stonework, of any age, and prevents the return of patio black spot. Our products are biodegradable and acid free. Our expertise in stone led us to develop this unique system and it’s why top garden centres throughout the UK have chosen to stock our pioneering brand.
