High-Performance EMF Shielding Paint for Exterior Walls (Powder)
Shield Exterior Performance is a highly effective EMF shielding paint for exterior applications.
Its innovative graphene technology provides exceptionally strong protection against high-frequency and low-frequency electromagnetic fields.
This shielding coating reliably protects buildings from mobile phone radiation, 5G, Wi-Fi, LTE, DECT and other wireless sources.
With proper grounding, low-frequency electric fields from household electricity can also be almost completely reduced or diverted.
The paint is supplied as a highly concentrated powder and is mixed with water just before application.
This ensures frost-safe shipping, long shelf life of several years and excellent coverage.
Advantages of Shield Exterior Performance
✔ Highly effective protection against electromagnetic radiation, mobile networks, Wi-Fi, LTE and 5G
✔ Shielding performance up to 65 dB
✔ Frequency shielding from 500 MHz to 40 GHz
✔ Innovative graphene technology (without graphene oxides)
✔ Long shelf life thanks to powder formulation
✔ Frost-safe shipping during winter
✔ Short drying time for fast application
✔ Wipe-resistant and durable after drying
✔ Can be painted over with exterior facade paint after a short time
✔ Suitable for private homes, office buildings, commercial properties and architectural projects
Powerful Shielding up to 40 GHz – Optimized for 5G
The key strength of this shielding paint is its excellent performance at very high frequencies, such as those used in modern mobile communication technologies.
The shielding effectiveness has been confirmed by an independent expert report.
Measurements were carried out by Professor Pauli (University of the Bundeswehr Munich).
The stated shielding attenuation values apply to frequencies between 500 MHz and 40 GHz.
This fully covers both 5G frequency ranges:
• FR1: 600 MHz – 6 GHz
• FR2: 24 GHz – 40 GHz
High-Performance Shielding Coating for Architecture and Facades
Shield Exterior Performance was developed for modern architecture, where electromagnetic radiation is increasingly becoming a design consideration.
The innovative graphene technology enables very high shielding performance combined with easy application.
This makes the coating ideal for:
• Residential homes
• Apartment buildings
• Office buildings
• Hotels
• Architectural projects
• Buildings located near mobile phone base stations
• Healthcare facilities
• Sensitive sleeping and resting areas
The shielding layer remains invisible beneath the facade paint and does not alter the building’s design or architecture.
This allows buildings to remain aesthetically pleasing while being protected from electromagnetic radiation (EMF).
Why Graphene Shielding Paint?
Graphene is one of the most electrically conductive materials in the world.
Combined with graphite, it creates a shielding coating that is particularly effective against:
• Mobile phone radiation
• Wi-Fi signals
• LTE
• 5G
• High-frequency wireless communication systems
This technology enables very high shielding attenuation even at frequencies up to 40 GHz.
Shielding Performance
The shielding performance has been confirmed by an independent expert report.
Measurement range: 500 MHz – 40 GHz
With a layer thickness of approx. 100 g/m²
| Coats | Shielding attenuation |
|---|---|
| 1 coat | 36 dB |
| 2 coats | 58 dB |
| 3 coats | 65 dB |
With a layer thickness of approx. 150 g/m²
| Coats | Shielding attenuation |
|---|---|
| 1 coat | 49 dB |
| 2 coats | 65 dB |
For reliable shielding performance we recommend at least two coats.
Easy Application
Application is simple and suitable for both DIY users and professional installers.
- Use the entire contents of the bag
- Mix the powder with 2.75 – 3.0 liters of water
- Stir for 10 minutes using a mixing tool or drill mixer
- Apply the paint like standard wall paint
Important:
Before each application, stir again for approx. 5 minutes, as conductive particles may settle in the bucket.
Once mixed, the paint should be used within approximately 6 weeks.
Suitable Substrates
Excellent adhesion on many surfaces:
▪ Previously painted facades
▪ Plaster
▪ Concrete
▪ Drywall
▪ Polystyrene
▪ Untreated wood
Top Coating for Exterior Use
The shielding paint is not designed for permanent direct weather exposure and must always be covered with an exterior facade paint.
Not recommended:
• Clay paints
• Pure mineral paints
• Pure silicate paints
For the following paints we recommend a prior adhesion test:
• Silicate emulsion paints
• Lime paints
• Casein paints

FAQ
Does the paint really shield against 5G?
Yes. Shielding performance has been measured up to 40 GHz, covering both 5G FR1 and FR2 frequency ranges.
Does the shielding paint need grounding?
Proper grounding is required to shield low-frequency electric fields.
Can the shielding paint be painted over?
Yes. For exterior use the coating must always be covered with facade paint to ensure long-term weather protection
