how can i fix perspex to plywood?

Need help how can I fit a perspex 5mm panel 1400 x 1100 to ply wood
that has been fitted to a brick wall?
The perspex is clear with a full colour image in reverse backed up in vinyl
can I just screw fix making sure the holes in the persex are quite big?

HELP

I would recommend putting in a panatrim frame,
Perspex is brittle and expands alot

If you are using Cast Acrylic , the acrylic expands in all directions , extruded expands along the direction its extruded - make your holes oversize to accomodate expansion , like a 3mm hole make 5mm and use a washer. you might need more than holes at each corner for that size perhaps 3 holes per side - dont screw the screws real tight , leave enough so that the perpsex "slides" as it expands.

We are unable to use a panatrim frame as it is fitting into a recess, so I think it has to be screwed in, what could I use to cover / disguise the screws?

Panatrim was designed to be used in recesses
Make sure you tell them when ordering that it is to be front-loaded
