Application instructions
- Substrate preparation: The aluminium surface must be clean, dry and free from dust and grease. Profiles must not be damaged (no scratches or corrosion). Clean the substrate with a cleaner such as Bostik Cleaner E and allow to dry thoroughly for at least 10 minutes.
- Handling the container: Keep the container closed until use, as PREP G PLUS reacts with moisture. Shake the can before use. An opened can must not be reused.
- Application: Apply with a clean foam roller. Close the container immediately after pouring the product, as it evaporates rapidly. It is recommended to apply in a single pass.
- Conditions: Apply between +5 °C and +30 °C. Avoid very humid conditions and very cold substrates.
- Before bonding: The primer must be non-tacky before the adhesive is applied. On aluminium, allow at least 30 minutes drying time. The adhesive should be applied within the first 24 hours.
