AllShield CreteShield - Durable Mineral Protection for Concrete
Mineral acid- and waterproof coating for protecting and repairing concrete
AllShield CreteShield is a two-component, ceramic mineral coating designed to protect and repair concrete. This fast-curing, mineral-based protective layer is ideal for fire protection, acid resistance, and structural repair of concrete surfaces. Applied as a seamless, reinforced layer, it makes concrete more resistant to acid attack (down to pH 2), reduces porosity, and prevents water ingress.
Applications include:
-
Protection of technical concrete constructions against water infiltration affecting sensitive control systems
-
Reinforcement of municipal concrete pits used for underground waste containers, preventing acid corrosion from household waste
-
General concrete structures exposed to water, acids, or aggressive environments
How CreteShield Works
CreteShield forms a reinforced, non-porous mineral shield on concrete surfaces. When applied with a glass fleece reinforcement, it becomes a flexible yet durable ceramic barrier that is:
Fast-curing and durable – engineered for long-term strength while allowing quick project turnaround
Acid-resistant – withstands aggressive waste acids down to pH 2
Waterproof – prevents water infiltration even under pressure
Seamless and UV-proof – no weak points or degradation under sunlight
Mineral-based and sustainable – PFAS-free, VOC-free, and low CO₂ footprint
Application
CreteShield is applied by certified applicators using airless spray technology. For maximum strength, it is reinforced with EKL™ 800/450 glass fleece. The result is a durable, seamless finish that bonds directly to concrete, without joints or gaps.
Certifications and Compliance
AllShield CreteShield
Testing and certifications are ongoing. CreteShield builds on the same mineral technology platform as AllShield Blue, which are tested and certified under multiple international standards for fire safety and durability.

Product information AllShield CreteShield
Engineered for durability and speed, AllShield CreteShield is designed to protect and repair concrete under the most demanding conditions. This fast-curing, mineral-based coating combines fire resistance, acid protection, and structural reinforcement in one seamless system. Its performance has been validated in real-world applications such as technical infrastructure and municipal waste facilities, where concrete is exposed to water, acids, and mechanical stress.

Projects AllShield CreteShield
Protecting what matters. Fire safety is the goal. Insurability the result. Our projects with AllShield CreteShield show how that promise becomes reality across sectors, applications and environments.
Frequently asked questions (FAQ) AllShield CreteShield
What is AllShield?
AllShield develops mineral-based coatings and barriers for fire safety, acid resistance and structural durability — with no plastics, no PFAS and a low CO₂ footprint.
Are AllShield products really non-combustible?
Yes. AllShield Blue is A1 certified and FM 4482 approved. BarrierSheet uses the same mineral composition and is undergoing FM testing.
Are your products compatible with common materials?
Yes. Proven on over 80% of standard materials including steel, EPS, PIR, PUR, bitumen, PVC, TPO, EPDM (for BarrierSheet), wood and concrete.
What types of buildings use AllShield?
Industrial, commercial and critical infrastructure buildings, especially those with flat roofs, PV systems, chemical zones or aging membranes.
Are your products sustainable?
Yes. AllShield products are VOC-free, REACH-compliant and developed to reduce the environmental impact of the built environment.
Do they work with solar panels?
Yes. Both products were specifically tested under PV systems and block fire spread effectively - horizontally and vertically.
Do they extend the lifespan of roofs?
Yes. AllShield Blue coating offers UV, mechanical and chemical resistance; BarrierSheet protects membranes and insulation as a cover board below a new roofing membrane.
Are they waterproof?
Both products act as a fire barrier and are not waterproof and cannot be used as a waterproof subsistute for a roofing membrane.
Can they be used in retrofitting roofs?
Yes. AllShield Blue is applied directly over existing waterproof membranes. BarrierSheet is installed under new membranes during re-roofing or re-roofing for PV retrofits.
What about insurers?
AllShield Blue is FM4482 approved and NEN 7250:2021 (under review) tested and widely accepted. For BarrierSheet, insurers increasingly recognize it as a fire safety solution, supported by field data and lab testing.
