Shielding Solutions EMF Shielding Paint YSHIELD HSF54 5 Liter

YSHIELD has a great product, its not cheap but is very effective at attenuating RFI. RFI is as issue almost everywhere you live in the city as there are masts and WiFi everywhere you turn. Our home is within 600' of one tower, 2 city blocks of another and three city blocks from a third. This almost seems to be the norm anymore. Then there's our neighbors WiFi which comes in very strong when using my EMFields AM-10. Plan on double priming the yshield before painting as black is a bit of a challange to cover with lighter colors such as white. Two coats does improve attenuation and paying attention to areas that may allow the RFI to leak in is important.

So, I can confirm that this does in fact block EMF. Whether or not you believe all the claims about the dangers of EMF radiation is an entirely different matter. For me, I bought a cheap, but effective, meter to measure the EMF around the walls of our bedrooms. I found that the worst wall was where may daughter's bed sits. While I'm not sure about all of the dangers, I do believe through lots of reading, that it does/can at least negatively affect sleep. This, along with all the other claims of danger, was enough for me to try something. After applying 2 coats of this product to that wall only, it reduced the readings on my meter by about 70% and put us safely under the "danger level." I feel much better now, so it was worth the price in my case. Again, research for yourself, but I can confirm the changes on my meter after application. This stuff works as stated.

Update: customer service has sent a replacement as well as noting in the system that packing material is necessary. Stars updated from 3 to 5 to reflect this.Product itself seems excellent in neighbors application. Massive reduction in measured signal from the nearby tower. Ordered two gallons and it shipped with zero packaging in an oversize box. Box arrived in very poor condition, one side had been taped over a failed initial layer of tape and only one gallon was present. Had to reschedule painters, interrupting a major appointment. Three tries so far at contacting customer support and over an hour waiting for understaffed CS department. Worth ordering in conjunction with an item that is generally packed well (like a cheap piece of glassware or perhaps a pillow) so you actually get what you order. Sorry I cannot yet comment on performance, but delivery issues others may also face seem to be a relevant reason to post a review. Will update with higher stars once I get a chance to do my own living room.

Unfortunately, it didn’t work. I really had high hopes spent 245 dollars on a tiny bucket, plus electrician $60, time off work and more paint which was $100 to cover the dark black plus brushes. So not worth it. Save your time and money. I have a meter and it didn’t make a difference.

It sort of works, but doesn't truly keep 5G out, if that's what you want. Nope. Not a good buy.

I have applied this paint to several rooms. It works! I'll be doing more rooms, especially if 5G comes to my neighborhood. It is alot of work because of all the coats of paint. But well worth it once your done. Make sure you prime your surfaces before putting on the shielding paint.Ends up being 6 coats…--1 coat primer--2 coats shielding paint--1 coat primer--2 coats colorFor the people who say it does not work, that is not true. You really need to put shielding curtains on the windows, as well. Then you will see a dramatic reduction in RFs. You can get shielding fabric that is sheer so you can still see out and get light.And reduce levels other ways, like wire your devices and turn off wifi at night.

I’m an RF engineer that’s worked with lots of very expensive conductive coatings. This paint is super easy to work with. It simply rolls on and cleans up with water. I conducted an RF attenuation test at a local NASA facility that yielded 40 to 50dB attenuation from 1Ghz to 20GHz with only two rolled on coats. It's also compatible with a wide range of cover coats. We'll be using this to enhance the RF shielding effectiveness of our clean rooms by using a gloss white top coat for ease of cleaning. I highly recommend this product.

Good paint, applied smoothly and easily
