Set in a quiet residential property in Horsham, this 48m² Indian sandstone patio is located in a shaded, north-facing garden. Due to the lack of direct sunlight and constant moisture retention during damp Sussex winters, the natural stone had developed severe biological growth over six seasons. Heavy green algae layers and deeply embedded black spot lichen (Verrucaria nigrescens) had completely obscured the stone’s original natural tones.
The owners believed the sandstone was permanently stained and beyond saving. Indian sandstone is a porous, delicate natural stone, and aggressive high-pressure washing can easily etch the surface, strip away natural mineral layers, and blow out mortar joints. We implemented a gentle, chemical-led soft wash restoration system designed specifically to target stubborn lichen without causing any physical damage to the stone.
Restoring delicate natural Indian sandstone requires a specialized approach to safely eliminate stubborn black spot lichen without eroding the stone’s surface texture or damaging surrounding garden elements.
