• Create the holes necessary to secure the mounting plate (Fig. C).
• In addition to the screwed connection, the mounting plate and roof gland must be bonded to the roof with
adhesive and sealed. This is done using the Sikafl ex
®
291 adhesive sealant supplied, which is ideally
suited for this purpose due to its broad range of adhesion.
Before starting to use Sikafl ex
®
291 adhesive sealant, be sure to read the Sikafl ex
®
Products safety
data sheet and technical data sheet in this installation manual!
The prerequisite for good adhesive properties is a clean, dry and grease-free substrate. You should therefore
clean the roof surface with a suitable cleaning agent within a circumference of 17 cm around the drilled hole
and allow the surface to dry thoroughly.
If the surface is painted, ensure that the paint fi nish is suffi ciently well bonded to the substrate.
If the coat of paint is already loose or peeling, it must be removed down to a stable layer in the area to which
the adhesive will bond. If you have any doubts concerning the adhesive characteristics, consult a paint and
lacquer specialist, or the manufacturer of your vehicle.
Under certain circumstances, it may be necessary for you to improve the adhesive characteristics of the roof
surface by pre-treatment with a cleaning agent available from specialist dealers (e.g. Sika
®
Cleaner) or a
primer (e.g. Sika
®
Primer).
The procedure for gluing the mounting plate is as follows:
