Introduction
The LIQUID GLASS Screen Protector by ProofTech is an advanced, invisible, wipe-on screen protection solution. It bonds to the glass surface of your device, providing enhanced resistance against scratches, moisture, and impacts. This product is designed to improve the durability of your device's screen without altering its appearance or touch responsiveness.
What is LIQUID GLASS? How Does it Work?
LIQUID GLASS is primarily composed of silicon dioxide (SiO2), which consists of microscopic glass particles suspended in a liquid solution. When applied, it fills the imperfections and microscopic pores on the screen's surface, creating an additional, extremely thin layer of glass. This process significantly increases the screen's strength to a 9H hardness level, making it highly scratch and shatter resistant. It is not a tempered glass or film, but a transparent liquid coating.

Application Instructions (Setup)
Follow these steps for optimal application of the LIQUID GLASS Screen Protector:
- Clean the Device: Thoroughly clean all glass surfaces of your device using the cleaning wipe provided in Sachet 1. Ensure the screen is free of dust, smudges, and debris.
- Apply Liquid Glass: Open the vial's cap and drip a few drops onto the center of the device screen. Use the dry wipe supplied to firmly rub the liquid into the glass. Begin with full strokes from top to bottom, then continue with a circular motion to ensure even coverage.
- Allow to Dry: Let the glass surface cure for at least 10 minutes. During this time, a residue may become visible on the surface.
- Buff & Shine: Use the microfiber cloth supplied to buff out any visible residue from the glass surface in a circular motion until the screen is clear and shiny.

Maintenance and Reapplication
While LIQUID GLASS is designed for long-lasting protection, reapplication is recommended for continued optimal performance.
- Reapplication Frequency: The unique formula can last up to two years, but it is recommended to re-apply once per year for sustained protection.
- Additional Layers: Multiple layers can be applied as desired to further enhance protection.
Important Information and Troubleshooting
Please note the following important points regarding your LIQUID GLASS Screen Protector:
- Not a Repair Solution: LIQUID GLASS should not be used to repair broken screens or fix existing scratches or damages. It is a preventative measure.
- Protection, Not Invincibility: While it significantly improves strength and scratch resistance, it will not make your screen completely shatter-proof or scratch-proof. Your screen can still get scratched or broken with LIQUID GLASS applied.
- Fingerprint Readers: LIQUID GLASS is 100% compatible with fingerprint readers and sensors.
- Tempered Glass Compatibility: A tempered glass protector can be applied on top of LIQUID GLASS once the liquid application has dried and been buffed.
- No Device Damage: The product has been rigorously tested and proven not to cause any damage to your device.
