Cementitious Fire Protection Mortar
Star Fire Shield Cementitious
Spray Fire Protection Mortar for Reinforced Concrete & Critical Infrastructure
Star Fire Shield Cementitious Spray is a one-part, wet-applied fire protection mortar built for reinforced concrete, tunnels, and critical infrastructure. Formulated with lightweight mineral aggregates and heat-resistant phyllosilicate materials, this cementitious spray creates a durable thermal barrier that slows heat transfer during intense hydrocarbon fires. It is designed for contractors, specifiers, and infrastructure owners who need dependable passive fire protection without the bulk of conventional concrete systems. Compared to standard coatings, this cementitious fire spray delivers efficient application, reliable coverage, and long-term structural protection where fire safety cannot be compromised.

The Problem
Why Do You Need Fire Protection for Concrete Structures?
Concrete Structures Lose Strength During Fire
High temperatures can rapidly weaken reinforced concrete, increasing the risk of structural damage, cracking, and premature failure during a fire.
Hydrocarbon Fires Cause Extreme Heat Damage
Industrial facilities, tunnels, and civil infrastructure are exposed to hydrocarbon fires that generate intense heat, exceeding the protection offered by conventional concrete alone.
High Fire Protection Thickness Increases Cost & Weight
Traditional fire protection systems often require thicker applications, adding extra material, weight, installation time, and overall project costs while reducing usable space.
Benefits
Reliable Passive Fire Protection with Star Fire Shield Cementitious
Star Fire Shield Cementitious Spray is a one-part, wet-applied fire protection mortar for reinforced concrete, tunnels, and critical infrastructure. Formulated with lightweight mineral aggregates and heat-resistant materials, it creates a durable thermal barrier that slows heat transfer during hydrocarbon fires. Designed for reliable passive fire protection, it provides efficient application, long-lasting performance, and enhanced structural fire resistance.
Lightweight Protection Without Compromise
Because the cementitious spray uses lightweight mineral aggregates, it delivers strong fire resistance without adding heavy dead load to structural members, helping engineers meet fire ratings while keeping structural design efficient and cost-effective long-term.
Fast, Efficient Wet Spray Application
The wet spray application method allows this cementitious fire spray to be applied quickly over large concrete surfaces, reducing labor time on site and helping contractors meet tight construction and refurbishment schedules on demanding projects.
Reliable Thermal Barrier Performance
The heat-resistant phyllosilicate-based materials form a stable thermal barrier that slows heat transfer into concrete, helping structural elements retain strength longer during intense hydrocarbon fires and reducing the risk of sudden structural failure across critical infrastructure.
Consistent Coverage on Complex Surfaces
Because it is designed for wet spray application, the cementitious spray settles evenly into irregular concrete profiles, corners, and reinforcement details, ensuring consistent thickness and complete fire protection coverage across the entire structure without gaps.
Flexible Fire Rating Compliance
Thickness can be adjusted to match the fire resistance rating specified for a project, allowing this cementitious fireproofing spray to meet varying regulatory and safety requirements across different structural elements and applications in various industries.
Simplified, Efficient Installation Process
As a one-part formulation, the cementitious spray removes the need for complex on-site mixing, cutting down installation errors and speeding up project timelines while maintaining reliable fire protection performance for every application on-site.
Method of Application
Star Fire Shield Cementitious Application Method
Surface Preparation
Prepare a sound, clean concrete substrate with a surface roughness of more than 2 mm. Before application, pre-dampen the concrete to a saturated surface dry (SSD) condition to ensure proper adhesion.
Mixing
Pour the recommended amount of clean water into a mixing container, gradually add Star Fire Shield Cementitious Spray powder while stirring slowly, and mix for at least 3 minutes until a smooth, uniform consistency is achieved. Adjust only within the recommended water limits.
Application
Apply using a suitable wet spray machine or approved spray equipment under appropriate site conditions. Avoid application in direct sunlight, strong winds, or extreme weather, and do not exceed the recommended water dosage to maintain optimum fire protection performance.

FAQs
Frequently Asked Questions
What is Star Fire Shield Cementitious Spray used for?
It is a passive fire protection mortar used to protect reinforced concrete and civil structures from intense hydrocarbon fires by slowing heat transfer to the substrate.
How is the cementitious spray applied?
It is applied using wet spray equipment, which allows fast and even coverage over concrete surfaces, including irregular shapes and reinforcement details.
What thickness of cementitious fire spray do I need?
Thickness depends on the fire resistance rating specified for your project. Higher ratings generally require a thicker applied layer of the cementitious spray.
Is this cementitious spray suitable for tunnels?
Yes, it is specifically formulated for tunnels, civil engineering structures, and other infrastructure exposed to hydrocarbon fire risk.
Does the cementitious fire spray require special mixing equipment?
It is a one-part formulation mixed with water, so it does not require complex multi-component mixing, though mechanical mixing equipment is recommended for consistency.
How does a cementitious fireproofing spray protect concrete during a fire?
It forms a thermal barrier using heat-resistant phyllosilicate-based aggregates, which slows heat transfer and helps concrete retain structural strength for longer during fire exposure.
Can the cementitious spray be used on both new and existing structures?
Yes, it can be applied to new reinforced concrete elements as well as existing structures during retrofit or refurbishment projects, provided surface preparation requirements are met.
What surface preparation is needed before applying this cementitious fire spray?
Surfaces must be clean, sound, and free of dust, oil, loose material, and standing water to ensure proper adhesion of the cementitious spray.
Is Star Fire Shield Cementitious Spray heavier than conventional fireproofing systems?
No, it uses lightweight mineral aggregates, so it adds fire protection without the excessive dead load associated with some conventional concrete-based systems.
Which industries use this cementitious fireproofing spray?
It is widely used in construction, tunneling, oil and gas, petrochemical, power generation, and marine or offshore infrastructure projects requiring passive fire protection.
