Screening attenuation: All stated attenuation values apply at 1 Ghz. Measurement to ASTM D4935-10 or IEEE Std 299-2006 or IEEEE Std 1128-1998 or ASTM A698/A698M-07. You find the test report above under "Report screening attenuation".
Grounding: Electrically conductive. Can be contacted and grounded to shield electric fields (LF). Please find corresponding components under "Grounding". A recommendation here is difficult because this depends on the application. Please ask us!
Application: Wall exterior, Wall interior, Ceiling, Floor
Field type: HF (High frequency electromagnetic fields), LF (Low frequency alternating electrical fields)
Ecology: High
Color: Black


Shielding plaster delivered as a powder. Dispersion silicate plaster with potassium silicate as binder and under 5 % synthetic content. For the shielding of high-frequency radiation (HF) and low-frequency electric fields (LF).

  • Delivered as a powder to mix yourself
  • Low shipping weight
  • Frost resistant on shipping
  • Shelf life for years
  • Breathable, solvent free, low-emission, low odor
  • Attenuation: 60 dB at 1 mm thickness, 70 dB at 2 mm thickness
  • Coverage: 20 m² at 1 mm thickness. 10 m² at 2 mm thickness
  • Packaging size: 12 kg powder for 20 liters of plaster

Special features

  • This shielding plaster contains no long carbon fibers for shielding, which is why it shields equally well in all polarisation directions.
  • This plaster has a relatively high diminution of 50 % while drying. This is very important for the high attenuation. It should only be used on smooth undergrounds as unevenness can’t be smoothed with this plaster.
  • Carbon pigments are black, in which shielding plaster would you trust? Instead of cheap filler materials, we use costly carbons exclusively, see the right sample in the picture. Thereby we don´t reach only 24 dB attenuation, but sensational 60 dB.

Safety instruction

This product with a pH-value of 12 contains potassium silicate powder. Stirring is only allowed with protective equipment! We urgent recommend our safety-set DRY99, see accessories.


As a thin layer plaster with a thickness from 1 mm to 2 mm preferrably interior. But due to the good moisture resistance even exterior.


Stir the 12 kg powder in a bucket with 12 liters of water. Preparation time appr. 70 minutes.


We recommend a surface preparation with our primer concentrate GK5 or another primer. Excellent adhesion on almost all absorbent undergrounds. Not applicable on gypsum based undergrounds, potassium silcate flake off from gypsum!

Final coating

Sand and smooth elevations and coarse burrs as usual. Normally on the graphite surface only organic dispersion paints or dispersion silicate paints adheres well. For pure mineralic coatings we recommend an aftertreatment with our primer concentrate GK5 or another for the coating suitable primer. Don´t use gypsum based coatings, gypsum peels off from silicate coatings!


Graphite, potassium silicate powder, carbon black, acrylic powder, additives.
