Attach glass to wood

Am I over rthinking it as usual?

Still going with the bathroom reno (geting there) and up to building the shaving cabinet.

Now the query. Want to attach/glue 4mm mirror to the doors. The plan is they will be 15mm bamboo ply like the rest of the piece. Now everything tells me that I need to do to both sides what I do to one, as with veneering????

2 doors about 350w x 700h.

Some options, some more complicated than others.
1 - use another substrate to attach mirror to and veneer back.
2 - the bamboo ply is a 3 ply material. I could remove the outer veneer and replace with mirror.
3 - just stick it on and hope for best.

Also any recommendations for adhesive?

Thanks for any help.

I will post some pictures of the vanity and cabinet soon.

If you really want to be safe, a piece of moisture resistant MDF or chipboard is probably best to stick the mirror to. The bamboo might be perfectly fine though, I've never used it.

You can get special mirror silicone to attach it, but any neutral cure silicone will do. A bead about 30-40mm in from the edge all around and a squiggle down the middle will be plenty, press it down firmly by hand and let it sit flat to cure for a day or at least overnight.

As Elan has said, natural cure silicone is the go. I form "calamari" rings of silicone on the back of the mirror. This gives the benefit of suction when the mirror is pressed into position.

I also thought of doing a series of vertical lines for the silicone and open at the bottom in case any moisture got in there it would just run down?
rustynail, does that mean you have done something similar to this?

I prefer the rings as the suction created when the glass is pressed into position helps hold while the silicone is curing. This method allows venting behind the mirror and any moisture can run down and out. Inside the rings becomes a sealed vacuum. I use this method for mirrors and splash backs.

Glaziers use the silicone like mentioned and double sided tape to hold it in place, supported by timber blocks until the silicone goes off
I think the other advantage of the double sided tape is it works like a spacer to keep an air gap behind the glass

I think the original question though is should both sides of the panel be treated the same, to prevent warping?

If it was me, I'd be sealing both sides as you will the rest of the piece, before applying the mirror, using neutral cure silicon as suggested. Maybe scratch up where the silicon will be.

Had you thought of using brackets like these ?

I don't think scratching the surface is a good move, it'll just create more potential entry points for water/steam. The silicon will stick just fine on a polished surface.

Interesting side note and possibly too late... Everything I've read about bamboo flooring says that it's not suitable for wet areas and should not be used in bathrooms. I'm assuming bamboo board is essentially the same stuff, so... :shrug:
