Tannin - Slate

Tannin stains, which often come from organic materials like leaves, wood, and plant debris, can be persistent on slate surfaces. Due to slate’s layered structure, these stains require a careful yet effective cleaning approach to prevent damage. PureSeal’s tannin removers are specially formulated to dissolve organic-based stains without risking delamination or altering the stone’s natural texture, ensuring slate’s original appearance is preserved.

These tannin removers penetrate the surface to lift stains completely, making them suitable for both fresh and older discolorations. For best results, carefully follow the product instructions, conduct a test patch to confirm compatibility, and use recommended PPE for safe application.
