INSTRUCTIONS FOR USE
- Surfaces must be clean, free of dust and grease.
- In very warm and moist climates, we recommend the use of PRIMER PU 900 for applications on porous surfaces.
- Use caulking gun.
- Repair with BONDFLEX 390FC.
- Finish with soapy water before skin formation.
- Cured material may be painted with most paints. When painted with oxidative drying paints, disturbances in the drying of the paints may occur.
A suitability test is recommended.
Not recommended for glazing applications and PVC.
JOINT SIZE
Minimum thickness: 2mm (bonding) / 5mm (joints)
Maximum thickness: 10mm (bonding) / 30mm (joints)
Minimum depth: 5mm (joints)
Recommendation: joints ≤ 12mm depth = width / joints > 12mm 2 × depth = width
CLEANING
Clean all equipment with white spirit immediately after use.
