Lead Oxide - Render

Lead oxide stains, typically appearing as brown marks, can form on lead flashing and nearby render when sodium hypochlorite reacts with lead components. This reaction leaves unsightly brown discolouration on lead that may transfer to surrounding render surfaces. When these stains occur, an acid-based solution is required to reverse the oxidation and effectively lift the brown staining, restoring the clean appearance of both the lead and adjacent render.

PureSeal’s lead oxide removers are designed to dissolve and remove these oxidation stains safely, restoring lead flashing and surrounding render to their natural look. For best results, apply the remover directly to the stained areas, follow product instructions closely, perform a test patch to confirm compatibility, and use appropriate PPE for safe handling. With PureSeal’s specialised solutions, professionals can effectively tackle lead oxide stains, rejuvenating both render and lead surfaces.
