The Crommelin Stain Repel is a clear, waterborne surface treatment that protects dense stone and concrete surfaces from staining agents and chemicals. Unlike simple sealers, it combines penetrating and film‑forming action to lock out oil, water and grime while still letting the substrate breathe. Furthermore, it contains an antimicrobial additive that helps prevent mould and algal growth, so treated areas stay cleaner and more durable over time.

Because it works on both natural and polished surfaces, Stain Repel gives you versatile protection across indoor and outdoor applications without changing the natural look of the substrate. Whether you’re sealing stone in a high‑traffic area or protecting concrete in a living space, it delivers reliable water, oil, and stain resistance where it matters most.
