I don’t know if that’s true. There is always a fair bit of conductive stuff in walls (wires, pipes, etc) that these sorts of systems already need to be able to handle in order to be interesting. The paints feel like they could easily be snake oil.
If OP really wants to do something about this, grounded chicken wire mesh should do the job, but that’s a lot more work.
Absolutely, chicken wire in the walls (if property set up) will do a lot. My point was that I have never run into rigorous third party testing around the paint, so the marketing may make it sound far better than it actually is.
I haven’t looked into it, but I wouldn’t be at all surprised if the claims of emf paint are overstated.
Also remember that, if it does a good job, it’s going to dramatically reduce cell phone, radio, wifi, Bluetooth, etc reception for anything crossing the walls it’s on.
Cool. Are you using anything beyond paint (mesh in the walls or something)? Also, what brand of paint?
It definitely seems like something that should be able to work (to some degree), but also something that it would be pretty easy to scam.
