YSHIELD’s shielding paint PRO54 is a pure acrylic based on carbon fibres with many advantages. It is ideally suited as a shielding paint for building shielding. 2019 revised again and further optimized for 5G. Now up to 53 dB shielding attenuation at 40 GHz. TÜV SÜD certified!
With this variant of shielding paint against electrosmog a big problem of graphite-based shielding paints is solved – the discolouration effect. Short explanation to the graphite topic: All graphite-based shielding paints are shock-sensitive, i.e. they stain black and thus become visible on the covering wall paint. However, graphite is necessary to create a high shielding performance against RF radiation (high-frequency electromagnetic radiation). This shielding paint PRO54 is therefore a compromise between high shielding performance and practical application.
Due to the base carbon fibres the shielding performance per coat is lower. This is a weakening in direct comparison. For this reason, triple coating is expressly recommended for the PRO54 shielding paint, while double coating is considered the minimum and a must. This means that shielding attenuation values comparable to graphite-containing shielding paints are possible again, i.e. between 40 dB and 50 dB. The slightly higher costs of the triple coating are however, in our opinion, compensated by the many advantages.
Convincing properties of the PRO54 shielding paint
From a technical point of view, the PRO54 shielding paint is one of the most durable and modern shielding paints. With regard to the carbon fibre base, the PRO54 shielding paint is unique in itself. The other unique advantages are:
- No colour fade: no discolouration when painting over with white wall paint, for example.
- Shockproof: Shocks against the wall paint no longer cause black stripes.
- Rough surface: Painting over the shielding paint is almost ideal. The surface of the PRO54 shielding paint film is microporous and rough and offer a nice substrate to top coatings for excellent adhesion.
- Resistance: PRO54 has an extremely high adhesive strength (adhesive force on the substrate) of 4.8 N/mm². That is twice that of regular graphite paints.
Yield of the PRO54 shielding paint
Generally speaking, the yield of a shielding paint is necessary depending on the surface. The more the surface “sucks”, ie. is colored, the more shielding paint is required. We recommend conducting small tests to see how quickly the paint “enters”. We highly recommend using our primer because that will prevent an excessively-high usage of PRO54 shielding paint. The “average” yield is based on a “non-sucking” surface.
- Up to 7.5 m² per liter is enough for INDOOR USE of PRO54
(single layer up to 7.5 m², two layers up to 3.75 m², three layers up to 2 m²)
- Up to 5.0 m² per liter is enough for OUTDOOR USE of PRO54
(single layer up to 5 m², two layers up to 2.5 m², three layers up to 1.25 m²)
You need to mix the PRO54 shielding paint extensively before applying it. The heavier ingredients will have sunk from storage and transport, and this must be corrected. With our stirrer, it is possible to effortlessly and effectively re-mix and re-apply the PRO54 shielding paint. Simply insert it into a standard electric drill and mix for around 5 minutes per container. There should be no more solid remains of the solid ingredients at the bottom of the container – these would make the shielding less effective because they wouldn’t be put on the wall, but they’d remain in the paint bucket.Stirrer for shielding paints GK5 primer
Mandatory grounding of the PRO54 shielding paint
All electrically conductive surfaces must be grounded by a qualified electrician in accordance to the DIN/VDE regulations. This can be done over the electrical system’s grounding support (ground contact in the socket) or on the grounded heating pipe of the wall heaters (radiator). A protective circuit also needs to be installed in the fuse box. It must be noted that the circuit must be turned off before painting – a 230-volt, 16-amp shock can be deadly! The electrified flush-mounted box must be a centimeter away when painting the wall.
Electrical alternating fields can be grounded, contrary to mobile radiations (high-frequency) which are based on reflection and cannot be grounded as a result. A protection against mobile radiation is also based on reflection whereby the electromagnetic radiation is prevented from entering the room.
The PRO54 shielding paint shields against both emissions by grounding and reflecting electromagnetic radiations.Self-adhesive conductive grounding tape for shielding paint Conductive carbon fibers as an invisible alternative to the ground tape
PRO54 shielding paint technical information
- PRO54 shielding paint technical information
Single-layer at 1 GHz shields PRO54 up to 32 dB, two-layer up to 40 dB and three-layer up to 48 dB. At higher frequencies WLAN, LTE, 5G and up to 40 GHz even higher up to 53 dB three-layered. All values provided apply for 1 GHz. Measurement from 40/600 MHz to 40 GHz according to standards ASTM D4935-10 or IEEE Std 299-2006.
- Application (coverage)
Interior (7.5 m² per liter), exterior (5 m² per liter)
Interior and exterior: Excellent adhesion on almost all undergrounds like existing emulsion paints, sheetrock, wallpaper, cement, plaster, masonry, wood, etc.
- Top coating
Preferably covered with plastic bonded, water-based emulsion paints, dispersion silicate paints, facade paints or silicon resin paints. Not applicable are pure mineral paints (clay, loam, chalk, silicate). Please find appropriate product recommendations in the technical data sheet. Due to the high adhesive tensile strenght (to ETAG 004 for EIFS-systems, minimum 0.08 N/mm²), applicable directly under pure organic plaster, no mineral pasters!
Must be grounded! For indoor use, we recommend our self-adhesive grounding tape and GW grounding plate GW (GB) and GP earth plug, and we recommend the AF3 fiber additive and GE grounding plate for outdoor use.
Water, pure acrylics dispersion, carbon fibers, natural graphite, carbon black, additives, preservative (BIT, INN, MIT).

The complete production process with quality assurance, the emission behaviour and the economical use of preservatives are subject to control. The certificate can be found above under “Documentation & Downloads”.
|YSHIELD shielding paints are developed according to strict ecological criteria. For example, the lowest emission carbon black on the market and untreated natural graphite are used.
YSHIELD deliberately avoids the use of graphene, a nanomaterial with a still completely unclear potential for danger.
