wet-guard water-resistant phone nano coating

My annual pilgrimage to the Vancouver International Boat Show took place last Friday. I’m pleased to report that I came home with “hopefully” a water-resistant phone. More on that to follow. I’ve been slow to post lately – sorry for that. A big announcement is coming explaining where my efforts have been focused these last few months.  Please stay tuned.

Best in show

Regional boat shows – like Vancouver – suffer a bit because they closely precede the looming Miami Boat Show. Marine electronics manufacturers are saving up their big announcements for a few more weeks. Shakespeare’s SuperHALO Cellular Booster Kit was awarded Pacific Yachting’s “Best In Show” in the electronics category. The booster kit has been out at least a year in its current form so it’s not particularly new. I have heard that it is a great but pricey product. The judging criteria is unknown to me. I wasn’t asked for my opinion.

wet-guard water-resistant phone nano coating brochureI would give an award to Wet-Guard because their nano-tech protection system for iPhones, Android phones, etc, is impressive. Wet-Guard converts a regular cell phone into a water-resistant phone in six “ish” minutes. They do tablets as well. Sorry Blackberry users, the technology doesn’t work with keyboard based cell phones. If you have an iPhone 7 (IP67), Galaxy S7 (IP68), Galaxy S5 (IP67), Sony Xperia Z5 (IP68), or the Motorola Moto G 3rd Gen (IP67), you won’t benefit much from the rest of this article.


The technology to nano-coat cell phones has been around for a few years. Companies like Impervious and Nanostate sell liquid for DIY application. The problem is that this approach is prone to user application error. Personally I don’t trust myself and my $600 iPhone SE with the application of nano-liquid. There are a few mail-away services that do it professionally but how long do you want to be without your precious phone?

Wet-Guard’s kiosk is designed for local professional application of a nano-coating using a portable thermal vacuum infusion chamber. The coating is one micron thick (one thousandth of a human hair) and doesn’t affect the conductivity of your charging port. Cost is CDN$30 for phones and CDN$50 for tablets. A pretty reasonable price to pay to guard against accidental submersion. Here’s the video I created to show how Wet-Guard makes a phone water-resistant.

I must admit to being apprehensive about handing over my phone to Devin Braden of Wet-Guard. Devin was sure enough of the technology to immerse his own nano-coated phone – while turned on – into a tray full of water which was the final persuasion I needed. The fact that they gave me a free treatment also helped!

A water-resistant phone emerges

What you don’t see in the video is that below the vacuum chamber is an oven which can bake on the nano-coating so you can get your phone wet right away. I’m too chicken to put my phone in an oven. The disadvantage of the oven is that the claimed effectiveness of the coating is then reduced to 12 months rather than 18-24. You supposedly get 18-24 months protection if you let the coating cure for 24 hours before getting the phone wet.

I have no plans to dunk my phone. I’ll feel a bit more secure pulling my phone out in a downpour though. If I do accidentally drop my phone in a puddle or the toilet, I’ll be sure to post a comment on my findings. Wet-Guard says that I’ll have 20 minutes to rescue my phone in up to 1 metre of water. I’ll end with the picture I took at the boat-show of Devin’s phone underwater. I’m too gutless to try it with my own phone…
