NS21 - Anti slip treatment

What is NS21? The Smarter Anti-Slip Treatment for Safer Floors

The Smarter Way to Make Floors Safe

NS21 is an advanced, professionally applied anti-slip floor treatment developed by Safety Direct Group. Using a patented aqueous-based polymer, NS21 chemically bonds with the surface to create a microscopic honeycomb structure, invisible to the eye but incredibly effective underfoot.

When walked on, this structure forms a gentle suction effect between the floor and footwear, instantly increasing traction, even in wet or greasy conditions.

It’s completely non-toxic, eco-friendly, and leaves no visible change, making it ideal for maintaining high safety standards without compromising appearance.
