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. An overview of key performance data is provided in the table below.

Projects AllShield CreteShield
Protecting what matters. Insurability starts with evidence. Our projects with AllShield CreteShield show how passive fire protection, low added roof load and documented system performance can be integrated into real commercial roof-PV projects
Frequently asked questions (FAQ)
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 and BarrierSheets are A1 certified.
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.
Can AllShield BarrierSheet and AllShield Blue be used with PV systems?
Yes. AllShield BarrierSheet is our standard solution for PV roof assemblies and is FM 4478 Approved for applicable roof assemblies. AllShield Blue is FM 4484 Approved and remains available as a specialty solution for selected existing roof applications.
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?
AllShield BarrierSheet is not a waterproofing layer and must always be covered by a waterproof roof membrane. AllShield Blue forms a seamless protective coating but is not intended to replace the primary roof waterproofing system or to repair an existing leaking roof.
Can AllShield BarrierSheet and AllShield Blue be used for roof refurbishment?
Yes. AllShield BarrierSheet is our standard solution for roof refurbishment and PV retrofits and is installed beneath a new waterproofing membrane. AllShield Blue can be applied directly to suitable existing waterproofing membranes in selected projects where retaining the existing membrane provides a clear practical advantage.
What about insurers?
AllShield Blue is FM 4482 and FM 4484 Approved. AllShield BarrierSheet is FM 4470 and FM 4478 Approved. Acceptance by an insurer always depends on the complete roof and PV assembly and the project-specific risk assessment.
