Has anyone ever used Parex profiles as insulated parapet cappings? If so, how did you fix them down?

Ah, now it's let me in!

This is from the pdf dealing with the decorative profiles...

INSTRUCTIONS
CONDITION AND PREPARATION OF SUBSTRATES
n Substrates must be sound, clean, dry and free from any mould oils.
n General line and level of the wall under a 2m rule: of 2m: < 5 mm.
n Waiting time for covering a new render is 21 days minimum, for concretes 45 days and
24 hours for reinforced base coat in MAITE MONOCOMPOSANT.
n The render surface must provide a sound bonding coat. (if required prepare the surface by
preliminary brushing with a hard nylon or wire brush).
n For concrete prepare the surface with MICRO GOBETIS 2000.
n The surface state of renders must provide a sound bonding coat or float-smoothed
(preliminary brushing with a hard nylon or metal brush), for concretes use the same
preparation as for when applying ceramic tiles.
EQUIPMENT REQUIRED
Trowel, smoothing trowel and notched trowel, handsaw, mitre saw with fine blades, mitre box,
set square (right angle), abrasive float, string line, slow speed electric paddle mixer.
ADHESIVE AND JOINT FILLING (can be coloured)
MAITE MONOCOMPOSANT (48 standard colours): powder mortar to be mixed with water at a
rate of approximately 5.1L per 30 kg bag (mix at slow speed until a smooth homogenous paste is
obtained).
n Rest time: 5 to 10 minutes before use.
n Practical using time: maximum 1 hour depending on atmospheric conditions.
n Consumption: minimum of 4 kg/m2 for adhering.
APPLICATION
APPLYING DECORATIVE FEATURES
n Mark the position of the features on to the façade. If necessary, place a temporary support
along the bottom edge. Large profiles may require additional support by using appropriate
non corrosive fixings.
n Cut features to desired size.
n Apply a regular thickness of MAITE MONOCOMPOSANT adhesive to the substrate, back and
ends of the feature with a notched trowel.
n Apply the feature onto substrate with a light sliding motion, applying enough pressure to allow
good contact between the 2 adhering layers (adhesive must be squashed in a continuous
layer, particularly along the upper section of the adhered side).
n Carefully remove excess adhesive.
n Carefully point the gaps between the features (5 mm approximate width of gaps).
n Remove any temporary supports a minimum of 12 hours after bonding.
FINISHING COAT
n This can be applied after the adhesive has dried, a minimum of 24 hours depending

When I closed down the 'update' page the pdf was sitting under it waiting to be discovered!

Depands on substraits

If brick/block then i would think parex would suggest there MAITE MONOCOMPOSANT adhesive, they suggest it for just about everything else, and its good.

If timber (ply) then check out discussion on GBF "bonding fixing EPS to OSB"
