Does RF blocking paint effectively improve WiFi performance by reducing interference from neighboring networks?

The experiment with high-concentration graphite RF blocking paint showed mixed but promising results for WiFi performance improvement. On the 2.4 GHz spectrum, the paint demonstrated significant benefits with a 20% improvement in the bathroom and an impressive 27% boost in the living room, with kitchen performance falling between these values. However, the 5 GHz spectrum showed minimal improvement, with only 1-2% enhancement observed during testing. This suggests that RF blocking paint is more effective at filtering interference on lower frequency bands, where congestion from neighboring networks is typically more problematic. While not a universal solution for all WiFi issues, RF blocking paint appears to be a viable unconventional approach for improving 2.4 GHz network performance in high-interference environments like apartments.
