Cementitious Coating

Cementitious Coatings:

Cementitious coatings for steel structures are protective coatings that consist of cement-based materials and additives designed to adhere to steel surfaces. These coatings are used to provide corrosion protection, fire resistance, and improved durability to steel structures in various industries such as construction, infrastructure, and marine applications. They offer several benefits, including:
  1. Corrosion Protection: Cementitious coatings create a barrier between the steel surface and the surrounding environment, helping to prevent the penetration of moisture, oxygen, and other corrosive agents. This is especially important in environments where steel is exposed to harsh weather conditions or chemicals.
  2. Fire Resistance: Cementitious coatings have excellent fire-resistant properties, which can help to protect steel structures in case of fire. The coating acts as an insulating layer, delaying the increase in temperature of the steel and allowing additional time for evacuation and firefighting efforts.
  3. Durability and Longevity: Properly applied cementitious coatings can extend the service life of steel structures by providing a durable protective layer that resists degradation due to environmental factors.

  1. Adhesion: It adhere well to steel surfaces, creating a strong bond that helps to ensure long-term performance.
  2. Ease of Application: It can be applied using various methods, such as spray, brush, or trowel, making them relatively easy to install.
  3. Chemical Resistance: Depending on the formulation, some cementitious coatings can also offer resistance to certain chemicals, which can be advantageous in industrial settings.

When considering cementitious coatings for steel structures, it’s important to take into account factors such as the intended application, environmental conditions, required thickness, and compatibility with existing coatings or substrates. Additionally, proper surface preparation is essential for achieving effective adhesion and performance of the coating.

 

It’s worth noting that there are different types of coatings available, each with its own specific properties and applications. Some common types include:

 

  1. Portland Cement-Based Coatings: These coatings are composed primarily of Portland cement and may contain additives to improve adhesion, flexibility, and other properties.
  2. Magnesium Phosphate Cement-Based Coatings: These coatings use magnesium phosphate cement as a binder, offering rapid curing and good adhesion to steel surfaces.
  3. Calcium Aluminate Cement-Based Coatings: These coatings are based on calcium aluminate cement and are known for their high-temperature resistance and rapid setting.
  4. Sprayed Cementitious Coatings: These coatings are often applied using spray equipment, allowing for efficient coverage and consistent thickness.
 

Always consult with coating manufacturers and industry experts to determine the most suitable cementitious coating system for your specific steel structure and project requirements. Proper surface preparation, application techniques, and maintenance are crucial for ensuring the longevity and effectiveness of the coating.

Cementitious Fireproofing in Dubai and the UAE

Cementitious fireproofing is a cement-based coating sprayed onto structural steel, decks and concrete to protect them in a fire. It forms a durable layer that slows heat reaching the steel, so the structure keeps its strength for the rated period. Evora applies cementitious fire proofing in Dubai, Abu Dhabi and across the UAE.

Where cementitious fireproofing is used

  • Structural steel beams, columns and decks that will be hidden or finished later
  • Plant rooms, car parks, warehouses and industrial buildings
  • Concrete and steel elements that need a durable, thicker protective layer

Cementitious coating or intumescent paint?

Cementitious spray is a thicker, rougher layer, so it is usually chosen where appearance is not the priority. Intumescent paint is thinner and gives a smoother finish for steel that stays visible. The right system depends on the fire rating, the element and the finish. We help you choose.

How we apply it

  1. We review the steel or concrete, the fire rating and the access.
  2. We prepare and protect the surrounding area and the surface.
  3. We spray the cementitious coating to the required thickness.
  4. We inspect the finished work before handover.
