I need to make three mirror props for a recital. They would be nominally 6 feet tall and 3 feet wide. And they will be flown in and out.
I searched through previous posts on the subject, found some useful information, and I have come to the conclusion that “standard” reflective silver mylar is the material of choice. (The Rosco heat-shrinkable mylar is too expensive.) I’ve located rolls of 2 mil mylar on the internet. (Again price is an issue, so I don’t think I’ll get thicker material.)
For a frame/support, I plan to use 2-inch rigid pink insulation board (rather than make flats.)
Before I start this, a few questions:
How durable is the 2 mil mylar? I have to make the mirrors at the studio and then transport them to the venue. (It’s been a while since those last posts, so if anyone has any experience it would be approcaited.)
To attach the mylar to the insulation board, I plan to run a bead of glue (Elmers glue) along the edge of the board. (Then, I’ll attach a narrow border – cardboard, ribbon [it’s a detail for now] – to cover the bead.) Will the elmer’s glue bond the mylar to the insulation? Is there a better glue to consider? I also thought about a spray adhesive over the entire board so that the mylar will stay flat. I tested 3M “77” and Duro Spray Adhesive on an old piece of insulation and both attack the board (the Duro more so that the 3M). Are there any other spray adhesives?
