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.
