Hi all ,
I have a job to install some acrylic mirror onto existing wall mounted mdf panels replacing glass mirrors (no adhesive on them) in a gym. I am wondering about adhesives and technique to make them as flat and true as possible they are 4' x 6' each vertical x 6pieces edge to edge. 3mm acrylic has a fair flex to it and I want to avoid any distortion. thanks for your thoughts.
 
I don't envy you this job!!

Unless your MDf panels are seriously flat and true, then EVERY bit of that "unflatness" will show. These have a good chance of becoming funhouse mirrors because the 3mm is basically too thin for the size and the need.

These acrylic mirrors needed to be much thicker to work properly.

That is why glass is the better choice here.

Why did you get the job instead of a glass installer business?

Just my 2¢.
 
the previously installed 5mm mirror is broken by gym activities thus the request for acrylic. I have not found thicker acrylic mirror.
 
Your only saving grace here would be if you can glue them down to
the substrate.
Roll glue on both.... the back of the mirror first.. then the mdf.

You can roll white glue, Frank's Fabric adhesive, Miracle Suck,
Lacaux . . . any will do.

roll em and stick up..... anything less..... wave bye bye
 
Distortions in mirrors only really show when they reflect a straight line. Even big pieces of thickish glass will bend to conform to a twisty frame.

Sometimes this has a dubious flattering effect by making the looker appear thinner. :smiley:

...like the funhouse mirrors I mentioned. Right? Right?:icon11:
 
A quick google search turns up a couple of places that carry 1/4" thick acrylic mirror.

Yeah, but a tad more subtle. :p

I've heard of staff in clothes shops jamming a matchstick under a rabbet to impart a bit of a concavity in mirrors. Takes pounds off apparently....
