Ideal supports for DuPont™ Corian® are:
•
Water-resistant
g ypsum
board
•
Moisture-resistant
plywood
•
Moisture-resistant

When covering old tiles, remove all loose and broken tiles. All tiles must be cleaned with
clear
denatured
alcohol
prior
to
fixing

to

surface.
The
installation
must
allow
for
expansion
and
contraction,
and
as
a
result
flexible
adhesives should be used.
There are two types of seams for vertical applications:
1. Caulked “V” seam
The caulked “V” seam uses colourmatched Corian® silicone sealant.
The face edges are chamfered to form
a small “V”.

The design versatility and performance features of DuPont™ Corian® - the availability
of
different
colours
and
aesthetics,
custom
colours,
textures
and
finishes,
the
ability
to
shape and form the material, and its exceptional durability and renewability - have led
a number of architects and designers to use DuPont™ Corian® for exterior applications.
These have included street signage and benches, bus stop canopies and shop facades,
and more recently even façade cladding. To satisfy this growing interest, DuPont has
developed a testing program to evaluate the potential of DuPont™ Corian® for exterior
applications.

In general, DuPont™ Corian® offers good resistance to UV rays, but certain colours
perform better than others in terms of weather resistance and fading. While the physical
properties of DuPont™ Corian® are not adversely affected by outdoor exposure, surface
gloss can be reduced.
Contrast between veining and background colour may be reduced and slight background
colour changes may be observed over time. These changes can be removed by periodic
sanding, but this refurbishing step is not always practical, such as in cases where
DuPont™ Corian® is used for covering large architectural surfaces like building façades.
The table on the right-hand page shows which colours are most suitable for exterior
cladding.
When using DuPont™ Corian® in exterior applications, it is especially important to
mount the material on a substrate or sub-frame using a method that allows for the
thermal contraction/expansion of the material.
