EMF-Turtal EMF Shielding Paint 2.5L - Powder (Indoor)
Product Overview
EMF-Turtal PLV 2.5 (Indoor) is a carbon-based conductive shielding paint supplied in powder form. One bag mixed with 2 L of water yields 2.75–3 L of ready-to-use paint, covering 10–12.5 m² (108–135 sq ft) per coat. The carbon/graphite/graphene formula shields high-frequency RF — Wi-Fi, DECT, GSM, LTE, 5G — across 500 MHz to 40 GHz, including both 5G FR1 (600 MHz – 6 GHz) and FR2 (24–40 GHz) bands. Shielding effectiveness has been independently tested by Prof. Pauli at the University of the German Federal Armed Forces in Munich.
Sold as a frost-resistant powder for indefinite storage life. Low-odour, low-emission and solvent-free — suitable for occupied interior spaces. Excellent adhesion to plaster, plasterboard, concrete, polystyrene, untreated wood, wallpaper and previously painted surfaces.
EMF paints are electrically conductive and must be earthed in accordance with electrical regulations by a qualified electrician. Grounding plates can be purchased here.

Frequently Asked Questions
Application
On which surfaces can EMF-Turtal be applied? Suitable for primed surfaces such as plaster, concrete, stone, plasterboard, gypsum fibre boards, woodchip wallpaper, paper wallpaper, non-woven paints, dispersion and silicate paints. Unsuitable for glue or lime paints, oil paints, plastic, metal or painted wood.
Can EMF-Turtal be painted on wallpaper? Yes — always wallpaper first, then paint. Do not use shielding paint under wallpaper as the adhesive may reduce shielding performance.
Can I coat EMF-Turtal with a wall paint? Yes, with a conventional dispersion paint. Unsuitable finishes are glue paints, lime paints and oil paints.
Do I have to prime the walls first? All untreated and absorbent substrates must be primed. Do not prime dispersion paints — clean them well instead; sand glossy dispersion paints. Untreated paper wallpapers can be coated directly.
How much water do I add? Add one bag to a 10 L bucket with 1.50–1.75 L (0.40–0.46 US gal) water and stir vigorously with a drill and whisk for at least 10 minutes. Leave to stand for 10–20 minutes, stir again for 1–2 minutes, then apply.
Grounding
Can I do the grounding myself? No — earthing must be connected by a qualified electrician. The shielding paint is electrically conductive, so live parts must never contact the paint.
Must each wall be grounded separately? Where possible, ground each wall that contains a socket separately. If only one socket is available, run grounding tape from that point across all walls and then coat with shielding paint.
Shielding
Why does the package quote 29–58 dB? These are mean values for two layers at 200 g/m². Actual attenuation varies by frequency — for example ~65 dB at 40 GHz and ~38 dB at 5.8 GHz.
Does it have to be painted twice? Yes. Two coats are required for the rated shielding performance.

Important Safety Notice
Do not use Wi-Fi or mobile phones inside fully shielded rooms. The shielding paint is reflective — radiation generated within a shielded room can be amplified by internal reflections. Have radiation exposure assessed by qualified personnel before any shielding measure is implemented. For professional RF shielding, windows and doors may also need to be shielded.
Always mix a complete bag of PLV 2.5. Never use only part of a bag — heavier particles settle during transport. Always stir again before each use and before applying the second coat.
