EMF Blocking Paint (YShield)
HSF45 is a water-based graphite and carbon conductive paint. It comes in one color: black.
I really like Yshield paint because it’s simple to use, has great customer reviews, works as intended, and provides very high levels of radiation protection and RF shielding.
Depending on the size of your home or area you want to paint, this can get expensive quickly as a 5-litre pail costs over $200.00. The more coats you apply, the better attenuation you achieve.
The manufacturer claims to achieve up to a 59 dB reduction in radio frequency with three coats of paint. If you need a primer on what db means, see this article, however essentially it’s a measurement of a material or product’s shielding effectiveness. Roughly, a 59 db loss means the paint is blocking 99.9999% of the radio frequencies.
One coat of paint will produce a 39b loss (99.99%) and two coats will achieve a 49db loss (99.999%).
