1. - General notes
- Bonding at room and object temperature of 18 to 25 °C.
- Newly painted parts may only be bonded after a drying time of at least 24 hours.
- Optimal attachment of the film to the background surface is achieved after approx. 48 hours. Film must not be exposed to mechanical strain beforehand (car wash, strength test, etc.).
2. - Auxiliary materials and tools
- Spirit, plastic squeegee, needle, cleaning cloth
- Low-surface-tension water
Note:
Mixture ratio: 3 drops low-surface-tension detergent to 1 liter tap water.
3. - Preparations
- If necessary, heat defective/old film with hot air blower and detach
- Remove all remnants of adhesive or clean new part thoroughly
- Clean the areas to be bonded with spirit immediately before bonding to remove silicone and grease residues.
Note:
Observe ventilation time ≥1 minutes.
4.
Bonding
4.1 - Moist bonding
- Thoroughly moisten the background surface to be bonded with low-surface-tension water.
- Pull off the backing film, position the film on the background surface and slide into position.
- Note: In the case of small-size film, the backing film can be pulled off completely and the adhesive side of the film can be moistened with low-surface-tension water.
- Press film down with plastic squeegee in overlapping strokes from inside outwards.
- Remove remaining water with a clean cloth.
- If necessary, carefully and slowly pull off protective film flat.
- Check film for bubbles and folds. If necessary, remove bubbles or folds with plastic squeegee or pierce with a needle and force out air or water.
4.2 - Dry bonding
- Pull off backing film on adhesive side.
- Align film in correct position on car.
- Press film down with plastic squeegee in overlapping strokes (watch out for formation of bubbles and folds).
- If necessary, carefully and slowly pull off protective film flat.
- If necessary, pierce bubbles with a needle and force out air with plastic squeegee.
