The electrically conductive grounding tape is essential when using shielding paints to protect against radiation, like a Faraday cage. Because this grounding tape is stuck onto the metal surface to contact it, the used tape is electrically conductive.
With metal-bearing shielding paints, electric fields are grabbed and grounded by this grounding tape. Without a functioning grounding, the shielding against electric fields will not work. Do not mistake that for protective effect against WLAN, mobile radio and other radio waves. High-frequency electromagnetic fields (radio radiation) are reflected and cannot be grounded.
Grounding shielding paint is mandatory!
The theme here is protection against a life-threatening electric shock. In the case of an electrically conductive shielding paint, there is a danger should it lead to a direct contact between the metal paint and the household power supply (220 volts, 16 amps), for example by drilling a hole in the wall that damages the power supply.
BE CAREFUL of thoughtlessly buying self-adhesive grounding tapes!
Alarmingly, self-adhesive grounding tapes that use a standard industrial tape are available on the market, and they are NOT ELECTRICALLY CONDUCTIVE! An insulating layer is inserted as a separator between the metal paint and grounding tape; as a result, the necessary grounding does not happen – DANGER! The adhesive for our self-adhesive grounding tape was designed specifically to meet our technical requirements.

Implementing a grounding with the grounding tape
In accordance with the valid EU requirements, all electrically conductive surfaces must be grounded by a qualified electrician. This is also a decisive risk topic for insurances.
Ideally, the grounding tape is grounded twice in each room, one grounding is necessary on the socket earth or the grounded radiator (heater), for example.
Applying the self-adhesive grounding tape
Ideally, the grounding tape is stuck on to the T98 shielding paint after painting the first coat on the wall and letting it dry. For the second tape, the grounding tape is also covered by the shielding paint and, as soon as it is dry, it is connected to the earth (socket or heater-radiator).
It is also possible to stick the grounding tape on only after the second coat. In this case, the entire grounding tape is subsequently painted over in order to ensure the full contact to the painted wall surface.
