Color Steel Plate Protective Film Installation Guide
To avoid wrinkling of the protective film during installation, follow these guidelines covering preparation, installation process, and environmental factors.
1. Surface Preparation
Proper surface cleaning is essential for smooth film application.
- Use dust-free cloth and special cleaner
- Thoroughly remove dust, oil, and water stains
- Check and polish welds and protrusions at corners
- Ensure surface is completely flat
2. Film Pre-Treatment
Proper film handling prevents stress-related wrinkles.
- Lay film flat for ≥30 minutes to release internal stress
- Leave 2-3cm margin around edges
- For long boards, apply film in sections
- Cut to size before application
3. Precise Application
The three-point positioning method ensures even application.
- Use "three-point positioning" method
- First fix top midpoint and left/right edges
- Slowly peel backing paper from center outward
- Use rubber scraper at uniform speed
4. Environmental Control
Optimal conditions prevent application issues.
- Avoid when humidity >85% or wind >3 level
- Maintain temperature at 15-25℃
- Use heater for low-temperature preheating
- Indoor application preferred
5. Tool Usage
Proper tools prevent damage during application.
- Wrap scraper with soft cloth
- For small wrinkles: gently push with fingers + scraper
- Cut excess corners at 45° angle with plastic cutter
- Use only plastic or rubber tools
6. Final Inspection
Timely adjustments ensure perfect results.
- Let stand for 1 hour after application
- Focus inspection on wrinkle-prone areas
- Lift and re-paste immediately if needed
- No adjustments after 24 hours
Following these six steps systematically will help achieve wrinkle-free protective film application on color steel plates.
