Indian sandstone patio beside planted border
A shaded sandstone patio next to a hydrangea border cleaned back to its natural tones in Winchester.
Borders and overhanging planting keep a patio damp, so algae takes hold quickly along the edges. In Winchester the slabs were softwashed with a specialist product, left to dwell, then rinsed gently with the planting protected so the stone colour returned without scarring.
