What silicone to seal the edges of a bathroom mirror?

Hello

I have installed this mirror in my bathroom - the instructions recommend "Sealing the edges of the Mirror - Please allow 7 days before sealing the edges for the product to cure. Apply a thin layer of clear silicone caulking to the crease between the mirror frame and the wall...Clear silicone caulking is waterproof, which prevents any water from getting in underneath the mirror."

I'm just wondering what silicone to use, given that I had to use special mirror liquid nails to secure it onto the walls. Will Sellys wet area silicone be ok? Or might it have a negative impact on the mirror?

Here are similar instructions.

Thanks!

Hi @tremas,

Was it the Selleys 310g Liquid Nails Mirror Metal And Glass Adhesive that you used to adhere the mirror? If so, that's a neutral cure silicone and can also be used to seal the mirror around its edge.

You'll need a neutral cure silicone, and Selleys 300g Wet Area Waterproof Silicone Sealant - Clear would also be suitable.

Please let me know if you need further assistance or have questions.

Great, yes that was the one - will use that for sealing too!

Hi @MitchellMc , I purchased some Selleys Wet Area clear silicone from Bunnings as I was hoping to seal my mirror and stop it from deslivering as it says "Selleys Wet Area is a 100% neutral cure" but then I saw your comment. Can you confirm whether it's ok to use to seal my mirror?

Hi @alexreed092,

I didn't actually think the Selleys Wet Area was a neutral cure, but it certainly references that on the packaging. I've updated my previous post to avoid confusion in the future. You're fine to use it for your project.

Thanks @MitchellMc , any tips for how to apply the silicone to a mirror that has already been installed to stop it from blacking? Would sealing the gap between the mirror and cabinet be the best way to go, or applying the silicone to the edges of the mirror?

You just really need to seal the mirror to the backing/cabinet @alexreed092. The idea is that you want to stop moisture from getting to the side of the silvering and the rear of the mirror. No need to seal the entire edge of the mirror, since the silvering is a thin layer on the back. A small cove of silicone from the rear edge to the cabinet would be sufficient. One of these silicone cove tools would be helpful. Here's a useful guide: How to apply silicone sealant.

I've created the image below to illustrate.
