Concrete Protection Reinvented

Concrete, though robust and durable, is not inherently fire-resistant. Under high temperatures, concrete can spall and lose its structural integrity, leading to potential collapse. To address this, ATOL has been working with many manufacturers for over 25 years on coating systems that upgrade concrete, maintaining the retro look of buildings and saving time on construction programs.

One such high-performance intumescent coating can be applied to concrete surfaces to enhance their fire resistance. When exposed to extreme heat, the coating expands, forming an insulating layer that shields the underlying concrete from the fire’s heat. This process helps maintain the concrete’s structural integrity for longer, providing valuable time for evacuation and firefighting efforts.

Key Benefits of Intumescent Coatings for Concrete Protection

  1. Superior Fire Resistance: These coatings have been meticulously tested to provide up to 120 minutes of fire resistance, protecting concrete structures and providing valuable time to save lives during a fire incident.
  2. Versatile Application: Suitable for a wide range of concrete surfaces, including precast and cast-in-place concrete, intumescent coatings offer a reliable solution for various applications, such as commercial buildings, residential properties, and infrastructure projects.
  3. Aesthetic Flexibility: Unlike many other fire protection products, intumescent coatings maintain the natural look of the concrete surface. They can also be top-coated with paints to match the aesthetic requirements of any project.
  4. Ease of Application: These coatings can be easily applied by brush, roller, or spray, making them practical for new constructions and retrofitting existing structures.
  5. Compliance with Standards: Intumescent coatings comply with numerous international fire resistance standards, ensuring that structures meet regulatory requirements while enhancing safety.


Given the potential risks that fire poses to concrete structures, advanced intumescent coatings represent a significant advancement in fire protection technology. Enhancing the fire resistance of concrete, they offer a practical and effective solution to safeguard properties and lives. With seamless application and aesthetic versatility, these coatings are a critical component in modern construction and retrofitting projects.
