Lead Oxide - Brickwork

Lead oxide stains, often seen as brown discoloration, can form on lead flashing and transfer to nearby brickwork when sodium hypochlorite reacts with lead components. This reaction leaves unsightly brown marks that can detract from the appearance of both the lead and surrounding brick surfaces. To reverse this oxidation and lift the staining, an acid-based solution is necessary to restore the brickwork to its natural, clean state.

PureSeal’s lead oxide removers are specifically formulated to dissolve and eliminate these tough oxidation stains safely, revitalising both the lead flashing and adjacent brickwork. For optimal results, apply the remover directly to the affected areas, carefully follow the instructions, conduct a test patch to confirm compatibility, and wear suitable PPE to ensure safe application. With PureSeal’s targeted solutions, professionals can effectively remove lead oxide stains and refresh the look of both brick and lead surfaces.
