Foamworks suggests a qualified tradesmen with experience in lightweight moulding installation to perform and carry out installation.  We strongly advise against first time D.I.Y. persons attempting to install mouldings without professional assistance.
Now that the disclaimer is out of the way, here are some helpful tips for installation of Foamworks lightweight exterior mouldings.
Be sure that mouldings are always stored on a flat dry surface and out of direct sunlight for any extended period of time prior to installation. 
It is important that climate conditions continue to remain dry during installation and temperature stay be between 5 and 35 Celsius.  Be aware that temperatures can affect adhesive and sealant cure times.
Ensure both contacting surfaces are clean, dry and free of any loose particles prior to installation.
Only use adhesives and sealants that are polycarbonate , polystyrene, foam safe.  Foamworks Pty Ltd is not liable for any loss or damage caused by incompatible foam adhesives, sealants, paint, installation techniques or technical advise for any reasons.
Here are some popular adhesives and sealants you may already be familiar with.

Always strike a chalk line where the moulding is to be installed so they can be placed straight as possible.  Nails place along the chalk line can really help in supporting larger mouldings while the adhesive dries.   The nail holes will then get covered with sealant when it is applied around all the moulding edges for weatherproofing.
Special Note: Regarding Expanding Foam Adhesives (PU33, Bossman or Touch 'n Seal):
If you decide to use the illbruck PU033, Bosman or Touch 'n Seal, you need to keep in mind that these adhesive are an expanding foam adhesive, commonly use to fill large gaps between cladding and casement windows.  When used improperly on mouldings have a tendancy to expand creating gaps between your moulding and structure, not good. 
Therefore, so what you have to do is apply the adhesive to the moulding, press in place and move around a bit to eliminate air bubbles and then remove the moulding for just a few minutes (2-3min.) allowing the adhesive to become tacky.  A word of caution, do not become distracted for any reason, as these adhesives are very unforgiving and set quickly, which is part of their appeal as well.  .
If installing moulding across an expansion joint, the moulding likewise needs to have a similar sized gap carried through the moulding and filled with sealant. 
Using a masonry diamond circular saw blade works best for a smooth flat cut, because it has no teeth it will not tear at the EPS foam beads or cause chipping of the hard coating.

If a damond saw blade is not available try and get a finer tooth blade.
When doing mitred corners adding an extra +1.5mm to external corners and conversely subtracting a -1.5mm for internal corners can help for a better fit.   Always check the moulding against the wall before applying any glue.
When joining straight sections of mouldings together, use a mitre joint like the professionals.  They provide a larger glue contact surface area making for an even stronger joint.  With the additional benefit of masking that area so it becomes a less detectable. 
After installation you need to fill any gaps or damaged areas use an exterior patch powdered filler for concrete and masonry. 
There are several on the market made for filling and sealing concrete, masonry etc. that provide excellent adhesion, weather , water and mould resistant.

Davco makes a "Powder Mastic Tile Adhesive" that works well.  JPS Coatings has what they call "Flexi-Patch" that also works for filling any gaps.

All mouldings require a high quality sealant that is flexible, weatherproof, UV resistant,  paintable to be applied around all edges.
H.B. Fuller Ultra Clear Sealant is a highly flexible sealant which guns out white, then dries clear for easy application.

Likewise, it is important that mouldings get at least two coats of a quality weathershield 100% Acrylic Exterior paint.  Such as “Dulux Weathershield 100% Acrylic Exterior Paint” that has UV protection, resists mould, dirt, stains and cleans up easily with water.  A fresh coat of paint every 5-7 years will go a long way in protecting your investment.
