I'm looking to attach a 2'x8' piece of acrylic mirror to a sheet of ply with just an adhesive and not any mechanical fasteners. What are some good options? I went down to a local hardware store to check out all the 10.1-10.3 oz tubes and none of them mentioned acrylic.

Well it's changed to 2'x4' mirror plexi with mirror clips around it. Thistothat suggests e6000 or epoxy. Anyone have any luck with contact cement? I thought the mirror adhesive is just for mirror and not acrylic.

What about Super 77 spray adhesive and lightly sanding the back of the plexi mirror? Has anyone had success with that?

As Ron says, the adhesive is only sticking to the silvering on the back of he mirror, but if enough of he silvering on the back is "stuck" to the mounting surface it should work fine. Look for a void-filling adhesive (such as some of the construction adhesives), not a contact adhesive like the sprays. No matter how smooth your wood surface is it won't be as smooth as the mirror and there will be little spaces between them here & there. I suggest spreading the adhesive with a notched tile adhesive setting trowel and then pressing the mirror onto the prepared surface.

While making fake stained glass using an acrylic sheet in a wood frame, I found out the hard way that the liquid polyurethane we were coloring to make the stained glass makes an excellent bond between acrylic and wood, but also the wood frame to the plywood underneath...

My frame actually broke before the bond did...

My recommended construction adhesive would be Loctite PL Premium. Wear gloves when applying it, you won’t get the film off your hands for days.

What hasn't been said yet is that you MUST TEST IT FIRST. Lots of stuff out there for bonding plastics, but many of them will dissolve the mirror coating and leave visible bubbles wherever contact happened.

Edit: For what its worth, we use Loctite Power Grab

Mirror Mastic. Works great on acrylic mirror. Some of the other suggestions will destroy the mirror.
I liked Gunther which advertises as safe for acrylic.
Just google it.

This is a bad choice. 77 is a non permanent bond and he is using no fasteners.
