1. Cleaning the Surface Is Essential for Secure Adhesion

Before applying protective film, it's crucial to clean the surface. This is crucial for ensuring a tight bond between the film and the surface. Dust, oil, and other impurities on the surface can create a barrier between the film and the surface, preventing the film from fully adhering and weakening the adhesion.

This can lead to issues like warping and peeling during subsequent use. A clean surface allows the adhesive layer of the protective film to directly contact the surface, strengthening adhesion and extending the lifespan of the film, ensuring it performs its protective function better.

2. Failure to Clean the Surface Can Lead to Multiple Potential Safety Hazards

Skipping the surface clean and applying the protective film directly can lead to numerous safety hazards. First, impurities can cause bubbles to form between the protective film and the panel surface, which not only affects the appearance but also leaves the panel surface exposed to air bubbles, making it susceptible to scratches and corrosion.

• Second, oil stains have a certain viscosity, which can change the adhesive layer's adhesion, potentially causing the protective film to adhere too tightly or too loosely in certain areas. This can leave adhesive residue when removed, contaminating the color-coated steel sheet surface.
• Furthermore, prolonged contact between impurities and the film can cause localized oxidation on the panel surface, shortening its lifespan.

3. Use Correct Methods and Tools for Panel Cleaning

When cleaning color-coated steel sheet, it's crucial to use the appropriate cleaning method to avoid damaging the surface. Use a neutral detergent and gently wipe with a soft cloth or sponge to remove surface oil and dust.

• Avoid scraping tightly adhered impurities with sharp tools to avoid scratching the coating. Instead, soak the surface in the detergent for a while to soften the impurities before wiping.
• Avoid using strong acidic or alkaline cleaning agents during cleaning to prevent corrosion of the panel coating and damage to the appearance and performance of the color-coated steel sheet. Ensure that the panel surface remains in its original condition after cleaning.

4. Dry and Protect the Board After Cleaning

After cleaning the board, further preparation is necessary to ensure a successful application. Thoroughly dry the board with a clean, dry cloth to prevent any residual moisture from affecting the adhesive layer and causing the protective film to adhere poorly.

• If application cannot be performed immediately after cleaning, protect the board from further dust and impurities. A temporary dust sheet can be used, but be careful not to apply the dust sheet too tightly to the board surface to prevent markings.
• Wait until the board is completely dry and free of impurities before applying the protective film. This ensures a smooth application process and optimal adhesion.
