Easy to use, works perfectly for house E field
I had a bedroom with lots of wires behind an internal dry plasterboard wall and the floorspace beneath, where the E field across the wall was c. 1500 V/m and the air inside the room at c. 450 V/m. Bio building standards aim for 10V/m or less for sleeping. I used this paint on the wall and the floor, goes on easy with a roller no splashes, and earthed using an iron plate wired to the house earth. Bingo 0V/m on the wall and the airspace. Just one coat kills the E field from the wiring but still let's through the WiFi so I can still use the phone in bed. Primer over the top and painted to room colour. Perfect result. Great product.
