My name is Josh from Action Corrosion. I’m here today to talk about our product Glastion, which is a glass and mirror edge sealer.
In previous videos, we talked about the reasons why we get the seal ring on mirrors. And we went through the testing that we’ve done through Bureau Veritas to show in a chamber test the effectiveness of Glastion.
Bathrooms are a high humidity area and the primary reason why you see desilvering on the edge is because moisture enters that exposed edge and gets under the glass into the backing. The other reason why they desilver is through a chemical.
So, the cleaning chemicals that you use to claim a mirror will also result in blackening on the edge once it gets underneath the glass. Mirrors are manufactured differently to how they used to be manufactured.
There was a layer of copper under the older mirrors and that tend to provide longevity to the mirror. Whereas the modern day mirror doesn’t have that layer and tends to fail. That’s the information that we’ve received from installers and glaziers.
So, what we’ve got here is a real-world test and this is a brand-new mirror that I installed. And within three months, I might add, we didn’t put Glastion on there. We just wanted to see, how widespread the desilvering problem is. So it was not coated. And after three months, you can see here that the bottom edge and the top edge definitely has started to desilver which is amazing after three months.
So now that you’ve seen the problem with this mirror, what we’re going to do is show you how Glastion in liquid form an aerosol form is used to protect the future mirror from desilvering.
So Glastion has been on the market for four years now. And in that time we haven’t had any complaints about failure of the product on mirror or laminated glass. So, what we have here is the replacement mirror for my bathroom, with a mirror fail.
And it’s just a standard mirror, it’s got a bevelled edge on the face. I did mention that you do get the desilvering on the edge, but there are instances where you do get the silvering in the middle of the mirror, and that’s where the aerosol comes into play.
So basically, on the back here, you want to achieve a film build of 25 micron. And on the edge you strive to achieve a build of 50 micron. For mirror manufacturers and commercial applications, you can use a spray gun with a 0.8-millimetre tip, and that will give you a good, fine mist to do the back of the mirror. It’s really important to follow the safety instructions when using the product, we’re in an outdoor area here but we’ll still use a mask.
It’s important that the back of the mirror hasn’t got any grease or oil on it. If it does, it needs to be cleaned off with detergent and left the dry before you apply the product.
So, it’s a clear, hard, fast drying product that you should wait half an hour before the next coat goes on, you can see that I hit that outside edge last, because that’s where you want to get the thick of film build.
And you want to seal that back edge where the mirror meets the backing. So one aerosol can will do 12 square meters for a single coat. So, what we recommend is three coats to achieve 25 micron.
So, in liquid form, this is the smallest can, we’ve got it’s 250 mil and it will do 40 lineal meters of edge. And you’ve got to remember, you’re doing the edge of the mirror, but you’re also coming over the back the back and you want to come over at least 10 mil or one centimetre all the way along.
So, two coats will yield you 40 linear meters. Liquid does come in larger quantities for contractors and for manufacturers of mirror. So we’ve done our three coats of Glastion aerosol form to achieve our 25 micron on the back. And each time we’ve done a sweep of the outside edge, but now what we’re going to do, we’re going to use the liquid just to ensure that we get that 50 micron on that edge that we’re trying to achieve. You generally can’t get that with an aerosol. So, what we’re going to do is the liquid with a small brush,
Just going to follow the edge. What makes this product a stand out is that it has awesome adhesion to glass. And when you’re talking about laminated glass with an interlayer, this is exactly how you would apply it. You apply it with a paint brush or you can get an applicator brush if you want to cleaner finish, but what we’re actually doing, he is waterproofing the edge. So chemicals and moisture cannot get between the glass and the backing. So now the process is finished, we wait two hours after the last coat before we fix it to the wall. So just to recap, to treat the back of the mirror in its entirety, we use the aerosol can with three coats, half an hour between coats to achieve 25 micron.
Each time I’m doing a sweep of that, of that important edge. And then finally, we put one coat of the liquid on that edge to achieve that 50 micron. The other option is if you don’t want to do the whole back of the mirror, or you’ve got laminated glass, you would only make the liquid and you would just run along that, that exposed edge to waterproof the glass and interlayer for more information about Glastion and the other products in our range, please go to www.actioncorrosion.com.au.
