Lead Carbonate - Indian/Sandstone

Lead carbonate stains, often visible as white or greyish marks near lead fixtures, gutters, or roof edges, can be particularly challenging to remove from sandstone surfaces due to the stone’s porosity. These stains result from the natural weathering of lead, which reacts with carbon dioxide in the air and leaves behind a stubborn residue on surrounding stone. PureSeal’s lead carbonate removers are specifically formulated for sandstone, dissolving these deposits effectively without risking etching or altering the stone’s natural colour.

Given sandstone’s porous nature, it’s essential to use a product specifically designed to lift lead carbonate stains without relying on harsh acids that could harm the stone. For the best results, closely follow application instructions, test a small area beforehand to confirm compatibility, and use recommended PPE for safe handling. With PureSeal’s lead carbonate removal solutions, professionals can restore sandstone surfaces to their original, clean appearance, maintaining both the stone’s integrity and aesthetic.
