How to remove air bubbles from glass film

When applying a glass film , it's common for bubbles to form. Especially if small gaps or dust get in, it can look like it wasn't applied properly. But don't worry! Air bubbles are surprisingly easy to remove. This guide will explain in an easy-to-understand way what causes bubbles to form and how to remove them. Apply it neatly and enjoy a comfortable experience!

Why do bubbles form?

When applying a glass film, it is inevitable that bubbles will form. The cause of these bubbles is actually surprisingly simple, and there are several reasons for this.

1. Mistakes when pasting

If you don't apply the film straight or if it's even slightly off when you apply it, air will get in the gaps and create bubbles. Bubbles are especially likely to form if you apply the film with even the slightest bit of force or try to apply it in a hurry. It's important to apply it slowly and carefully.

2. Dust and debris

This is the most common cause. If you don't clean your screen before applying it, dust and other small particles of debris can get trapped between the film and the screen. This traps air and causes bubbles, especially if the dust particles are too small to be seen with the naked eye.

3. Effects of temperature and humidity

Temperature and humidity also have a surprising effect. For example, if the room is humid, the glass film will not adhere well to the screen and air bubbles will easily form. Also, if the temperature is extremely high, the film may become too soft and difficult to apply. It is best to work in a cool, dry place as much as possible.

4. Mistakes when reapplying

When you apply a film, you may find that air bubbles form, so you have to reapply it. However, if you remove the film and then reapply it without removing all the air, new bubbles may form. When reapplying the film, it is important to press out any air bubbles firmly.

Preparation for removing bubbles

If you prepare well before applying the glass film, you can prevent air bubbles from forming. Here, we will explain in detail the necessary tools, how to prepare your work area, and how to thoroughly clean the screen. Follow these steps to ensure a smooth application!

Gather the necessary tools

First, prepare the tools you need to remove the air bubbles. The following items will make the job easier:

Squeegee: Used to apply the film smoothly and remove any air bubbles. We recommend a plastic squeegee, as it is less likely to scratch the screen.
Microfiber cloth: A soft cloth for wiping the screen. This is essential for thoroughly removing dust and fingerprints.
Scotch tape: Use this to remove small dust particles and debris. Gently press the tape down to catch the dirt.
Air duster (dust removal spray): This is useful for blowing away dust from small areas of the screen. It also helps prevent static electricity.
Gloves (optional): For a cleaner process, use gloves to keep oils and dust from your hands off the film.

Organize your workspace

Next, prepare your work area. A clean environment will help prevent air bubbles from forming.

Choose a place with little dust

If there is a lot of dust, it will be easier for dust to get in when you apply the sticker. Choose a room that is as clean as possible and a place with little wind and where dust is less likely to fly around.

Ensure adequate lighting

It's easier to align the film in a well-lit area, so it's best to work in a location with natural light or under bright lighting.

Clean your screen

The key to success is to thoroughly clean your screen before applying the film. Follow these steps to thoroughly remove any dirt.

Power it off: To be safe, turn off your smartphone or tablet.
Wipe with a microfiber cloth: Gently wipe the entire screen with a soft cloth to remove fingerprints and oils.
Blow away dust with an air duster: Use an air duster to blow away any dust that has accumulated in the small crevices and corners of the screen, paying particular attention to the edges.
Remove any remaining dust with cellophane tape: Use cellophane tape to remove small particles that cannot be removed with just a cloth. Lightly press the tape and then slowly peel it off to make it easier for the dust to adhere.
Wipe again: Wipe the screen one last time with the cloth to ensure it is completely clean.

Handle the film with care

It is also important to keep the film itself clean when handling it. Please pay attention to the following points.

Carefully remove the protective sheet from the film: Carefully remove the protective sheet on the back of the film to avoid getting it dirty. Peel it off slowly from the edge to ensure a clean removal.

Hold the edge of the film: Hold the edge of the film instead of the center to prevent fingerprints and smudges from getting on it. Keep the area where you hold it as clean as possible.

Avoid touching the film too much: Touching the film directly with your fingers can cause oil and dirt to adhere to it. Try to avoid touching the surface of the film as much as possible.

How do I remove air bubbles from the screen protector?

If you notice any bubbles after applying the glass film, don't panic! Try the following simple steps to remove the bubbles!

Method 1: Use a spatula to push air bubbles outwards

This is the most basic method: use a squeegee to push the air bubbles out towards the edges of the screen.

Start at the center of the film

Once the film is attached, start by squeezing out any air bubbles from the center of the screen. Slide a spatula between the film and the screen, slowly working your way outwards.

The key is to press gently

If you press too hard with the spatula, you may tear the film or scratch the screen. Be sure to press gently and with consistent pressure.

Small bubbles may disappear naturally

If the bubbles are small, they may disappear on their own over time. You can wait a little while and then try using the spatula again.

Method 2: Remove dust with cellophane tape

If the bubbles are caused by dust or debris, removing them with some cellophane tape can be effective.

Lightly press the tape onto the film

Stretch a small piece of cellophane tape and press it gently over the air bubbles, allowing the tape to attract dust and debris.

Slowly peel off the tape

While still pressing the tape down, slowly peel it off, making sure that any dust or debris is still on the tape.

Repeat as needed

Repeat the process of using tape until the bubbles disappear. If there are large bubbles or multiple bubbles, it is a good idea to apply tape to only the bubbles.

Method 3: Reapply the film

If you can't get rid of the bubbles, you can try removing the film and reapplying it. This method takes a little more time, but it's a surefire way to remove the bubbles.

Carefully peel off the film

Peel the film slowly from the edge. Be careful not to pull too hard as this can tear the film or scratch the screen.

Clean the screen and film again

After removing the film, clean the screen again using a microfiber cloth, compressed air, and cellophane tape to remove all dust and debris.

Reapply the film

Once cleaning is complete, reapply the film, slowly working from the center outwards to avoid trapping air bubbles.

Push out air bubbles with a spatula

After reapplying the film, use a spatula to gently push out any air bubbles, working from the center outwards.

Additional Tips

Adjust the temperature
- If the film is cold, it will lose its adhesive strength and air bubbles will form. Warming the film slightly before applying it will improve its adhesive strength and reduce the chance of air bubbles forming. However, be careful not to heat it too much.
Work slowly
- Rushing can easily result in air bubbles, so taking your time and working carefully can help minimize them.
Prevent static electricity
- Static electricity can also cause bubbles, so wearing gloves or using anti-static spray can help.

These methods should be effective in removing air bubbles, and if one method doesn't work, try another.

The method for removing air bubbles from iPhone screen protectors is basically the same as for other smartphones, but there are a few points specific to iPhones that you should pay attention to. First, the areas around the iPhone's camera and sensors are precisely positioned, so it's important to align these parts properly when applying the screen protector. Also, since the latest iPhone models often have curved displays, be sure to pay particular attention to the curved areas when using a spatula to gently push out air bubbles from the center outward.
