Wilsonart Laminate mounting?

[derelicte]

So, I took the plunge and picked up a piece of Wilsonart Designer White for the basement. I got the thicker gauge so that I wouldn't have to worry as much about wrinkles.

My question is with regards to mounting it. I was contemplating just screwing it to the wall (pre-drill holes, use decorative washers, cover them up with black felt).
Most other posts (reading some on avsforum) talk about mounting the laminate to a frame first. While this makes it easier to take on & off the wall, is it necessary? A friend I was bouncing ideas off of asked if my wall was perfectly flat - it may not be "perfect", but I don't imagine it would be enough to notice (the thick gauge laminate should smooth out possible wrinkles and there are no big bulges or anything).

Anyone here done the laminate screen? Any thoughts? Suggestions?

Cheers!
