Copper Oxide - Render

Copper oxide stains, typically seen as blue or green discolouration, form when copper elements like pipes, fixtures, or nearby metalwork react with oxygen and moisture. This reaction can lead to persistent staining on render surfaces, creating unsightly marks that detract from the render’s natural appearance. PureSeal’s copper oxide removers are specially formulated to break down these challenging stains without affecting the render’s texture or colour.

Our removers are designed to dissolve copper oxide buildup effectively, lifting and clearing the stain to restore the render to its clean, original state. For best results, follow product instructions closely, perform a test patch to confirm compatibility, and use appropriate PPE for safe handling.
