Lead Carbonate - Limestone/Travertine

Lead carbonate stains, which often appear as white or grayish deposits near lead fixtures or roofing, can be particularly difficult to remove from porous limestone surfaces. These stains form when lead weathers and reacts with carbon dioxide, leaving unsightly residue that can be challenging to lift without damaging the stone. PureSeal’s lead carbonate removers are specifically formulated for limestone, breaking down these deposits effectively without causing etching or discoloration to the delicate calcite structure.

Due to limestone’s sensitivity, using a product designed to target lead carbonate without harsh acids is essential to preserve the stone’s natural appearance. For best results, follow product instructions closely, perform a test patch to ensure compatibility, and use the necessary PPE to ensure safe handling.
