Applying waterproof film is actually not difficult; mastering a few key techniques will get you right! The core is three points: thorough cleaning, patiently removing air bubbles, and keeping the environment dry. Below, I'll break down the specific steps for you; just follow along.
Preparation
Choose the right film and tools: Select a suitable waterproof film based on the area you want to apply it to (e.g., car window, rearview mirror, or glass). Remember to prepare a spray bottle (filled with clean water), a plastic squeegee or credit card, a clean towel, and a sharp film cutter.
Keep the environment dry: It's best to apply it on a sunny day when the temperature isn't too low, as this ensures good adhesive strength. If the weather is cold, you can use a hairdryer on a low heat setting to slightly warm the adhesive surface to soften the adhesive.
Core Application Steps
Thorough cleaning: Wipe the adhesive surface clean with detergent and a damp cloth to remove dust and oil. This is crucial to ensure it doesn't peel off.
Cutting and Positioning: Cut the film slightly larger than the actual size (leaving an extra 1-2 cm). Then peel off the protective film and start applying it from the center, slowly smoothing it out.
Spraying Water and Smoothing: Spray some water on both the film and the glass. Then use a squeegee to scrape from the center outwards, removing water and air bubbles, checking as you go.
Trimming and Drying: After smoothing, use a utility knife to trim off any excess. Then press with a dry towel to absorb moisture and let it air dry naturally or with cool air.
Application Methods for Different Areas
Car Rearview Mirror: Clean the mirror first, spray water, then apply the film. Carefully remove air bubbles with a squeegee, ensuring the edges conform to the curved surface. Trim slightly if necessary.
Car Window or Glass: The steps are similar, but car windows have a larger area, so spray water and smooth the film more carefully to avoid air bubbles and wrinkles.
