Tannin - Render

Tannin stains, often caused by organic materials like leaves, wood, or plant debris, can leave noticeable brown or yellow discolourations on render surfaces. These stains are particularly persistent on porous and textured render, where tannins can seep into the material. PureSeal’s tannin removers are specifically formulated to break down and lift these organic-based stains, restoring the render’s natural appearance without damaging its texture or finish.

For best results, apply the product directly to the affected area, allowing it to penetrate and dissolve the tannins effectively. Always conduct a test patch to confirm compatibility, carefully follow application instructions, and use appropriate PPE for safe handling. With PureSeal’s tannin removers, professionals can efficiently restore render surfaces, removing even stubborn organic stains and enhancing overall appearance.
