The chemical fastening system is the preferred choice for architects seeking a clean, minimalist aesthetic without visible fasteners. This method allows any façade design to be executed without the limitations of formed trays, as it works directly with the cut composite panel. It is the ideal solution for continuous flat surfaces and a visually homogeneous finish.
To ensure maximum structural safety and durability of the ventilated facade, it is essential to strictly follow the application steps with certified products (Sika range):
Deep cleaning: Clean the bonding area of the panel with Sika Cleaner 205 and allow to dry for a minimum of 10 minutes.
Technical primer: Apply Sikatack Panel Primer in the contact area. Respect a drying time between 15 and 60 minutes before the application of the adhesive.
Profile cleaning: Clean metal battens with Sika Cleaner 205 (omit this step for wooden battens). The standard maximum distance between battens is 60 cm.
Specific primer according to material:
Wood: Sika Primer 1 or Sikatack Panel Primer.
Aluminum: Sika Primer 210 T.
Steel: Sika Primer 204.
For other materials, please consult our technical department.
Double-sided tape: Apply a continuous bead of Sikatack Panel 3 Tape. Keep the protective paper until the last moment to avoid dust contamination.
Adhesive bead: Apply Sikatack Panel adhesive continuously parallel to the double-sided tape.
Panel attachment: Remove the protective paper from the tape, present the panel on the substructure without pressing to allow for position adjustments and, once aligned, press firmly to ensure full contact.
