Fixing large (2m) mirror to polished applestone

[Unregistered]

I am reluctant to use screws and caps to fix my mirror (~1m wide x 2m tall) in my bathroom as I think they detract from the 'look'. The mirror will be spaced about 25mm away from floor and ceiling and any adjacent walls, to avoid any expansion/contraction issues.
I've been told special mirror adhesive/sealant will do, but are there any precautions I need to take, or pitfalls to avoid?
I intend to support it on a suitable sized wood batten while the adhesive sets, but I'm not too sure how to avoid the batten becoming 'trapped' when the adhesive has set!
I've already presumed that I'll need to leave the application of a moisture-proof sealant around the edges until after the adhesive has had enough air/time to fully set.
Any help gratefully appreciated.

mirror adhesive for me mate

this one was stuck on with mirror adhesive and supported with plasterboard props, (telescopic) overnight. I put a sponge on the mirror face so as not to scratch it with the props

miror mate?

 

[doug boardley]

to stop it becoming trapped (the batten) place it on some glazing spacers, when the adhesive has set, pull out the glazing spacers and the batten will slide out easily

Thanks Guys; very helpful - the 'big stick-on' is tomorrow!

Same as Doug (above)

I ran a baton across the room to take the actual weight of the mirror.

Then covered the mirror and the plaster wall behind with mirror adhesive.

Squished together then prayed the glue lines would not bleed through when dry.

I believe the adhesive is constructed so that it wont react with the silver backing and show through...
