Lead Carbonate - Slate

Lead carbonate stains, typically seen as white or grayish deposits near lead fixtures or roofing, can be challenging to remove from slate surfaces. These stains occur as lead weathers and reacts with carbon dioxide, leaving behind residue that can be difficult to lift without impacting the stone’s natural layers. PureSeal’s lead carbonate removers are specially formulated for slate, effectively breaking down these deposits without causing discoloration or surface damage.

Since slate requires a gentle approach, using a product specifically designed to target lead carbonate without harsh acids is essential to preserve its natural appearance. For best results, follow product instructions carefully, conduct a small test patch to confirm compatibility, and use appropriate PPE for safe handling.
