A sheet of 3mm thick silver mirror acrylic
perspex size is 500mm x 1000mm x 3mm thick. **Note the mirrors in the photo are
larger than these ones the image is for illustration purpose only**. Ideal as a
replacement for regular glass mirror as this material is 10 times stronger than
glass and if broken does not leave loads of dangerous pieces. Being acrylic
this is also a lot lighter than glass and because of the clarity of the acrylic
sheet many even think that the reflection is better and clearer than glass
mirror. These sheets are supplied with a durable grey backing and can be
mounted to walls or ceiling by either drilling holes applying VHB tape. Please
note that if the wall or ceiling that these are being applied to is not totally
flat it may be best to fit these boards to a flat sheet of MDF or similar as
the sheets are flexible. Mirrored acrylic is a reflective film applied to a
substrate. When the substrate is affixed to another surface, both of these
materials will in time conform to the irregularities of the supporting surface.
A non-smooth, non-planar surface will cause localised bending of the mirrored
sheet and distortion in the reflected image. For best results, mirrored sheets
should be mounted to a smooth, rigid, sturdy flat backing such as 5/8" or
3/4" plywood. The surface should be coated with a high-quality paint or
sealant to cover pockets and seal out moisture. The entire surface should then
be covered with a mastic or another type of pressure sensitive adhesive.
Solvent cementing of a mirror sheet with a hard-coated surface is not readily
accomplishable due to the chemical resistance of the coating. Another option is
to drill oversized holes in the mirrored acrylic and hold it to the wall using
screw fasteners. Do not over tighten the screw fasteners. Over tightening
will cause dimpling and distortion. Visual distortion is a function of viewing
distance and material thickness. A thicker piece of material will be less
flexible and therefore maintain better optical integrity. Correct installation
and sufficient material thickness can reduce visual distortion but may not
completely eliminate it. Ceiling and overhead installations are not recommended
unless the mirrored acrylic is mounted in edge-engaging frames such as t-bar
suspended ceiling frames or mechanical mounting. Some adhesives may contain
solvents such as toluene, ketones and hexane that can attack the back coat. Adhesives
with solvents of 5% or more are not recommended. Since numerous adhesives,
cements and mastics are available, they should be tested on expendable pieces
prior to the application. All tests should be applied at least 72 hours in
advance to determine compatibility to the back coat, the reflective coating and
the acrylic itself. Any adhesive used must be applied totally even as any
un-even adhesive on the back with result in an un-even reflection. Please note
that when these sheets are delivered they will have a protective film covering
the face so the mirror will appear hazy but once the film has been removed the
true quality will be revealed.
