Applying Gila window film can enhance privacy, reduce glare, and improve energy efficiency in both residential and automotive environments. Whether tinting windows in a home or on a vehicle, proper preparation and technique are essential for a successful and long-lasting installation. This guide draws from official product manuals, application kits, and manufacturer instructions to provide a step-by-step approach for installing Gila window films. The instructions emphasize the importance of using the correct tools, cleaning the glass thoroughly, and following safety precautions to ensure optimal results.
Preparing for the Installation
Before beginning the installation process, it is crucial to gather the necessary tools and materials. The recommended tools include Gila Film Aid application concentrate or a "no-tears" baby shampoo, bottled water, a spray bottle, a squeegee, a break-away utility knife, a single-edged razor blade, a ruler or tape measure, and a soft, lint-free cloth or paper coffee filters. These items are essential for cleaning the glass, applying the film, and trimming any excess material.
For residential applications, Gila window films are applied to the inside surface of the glass that can be touched within the home. If a removable storm pane is present, it can be removed to apply the film to the outermost window surface before remounting the storm pane. This approach allows for better visibility and ease of installation. It is also recommended to practice on smaller windows before tackling larger ones, such as patio doors, which may require two people for a smoother application.
For automotive use, the installation process is similar but requires additional attention to legal requirements. Users are advised to check their state's laws regarding window tint light transmission and reflectance percentages. Information on these regulations can be found at www.iwfa.com/state-law-charts. It is important to note that dark tinting may reduce visibility during poor lighting conditions, so caution must be exercised during such times.
Cleaning the Window Surfaces
Thoroughly cleaning the window surfaces is a critical step in the installation process. The cleaner the glass, the better the final appearance of the film. For both residential and automotive installations, the same cleaning method applies. Begin by spraying the glass with a generous amount of Gila application solution or "no-tears" baby shampoo. A clean, lint-free cloth or paper coffee filters should be used to scrub the surface, paying special attention to the edges and corners of the window. Any stubborn dirt, tree sap, or dead bugs should be carefully scraped away using a single-edged razor blade. It is important to avoid using household glass cleaners, vinegar, or ammonia-based products immediately before applying the film, as these can leave residues that may interfere with adhesion.
After scrubbing, the window should be rinsed with clear water and dried using a squeegee. The squeegee blade should be held at a 45-degree angle to the window surface and dragged downward to remove excess water. This process should be repeated until the window is completely clean. For automotive applications, the same procedure should be followed for both the interior and exterior surfaces of the window. Special care must be taken when handling sharp objects, as they can damage the glass or cause injury.
Cutting and Preparing the Film
Once the window surfaces are clean and dry, the next step is to measure and cut the Gila film to the appropriate size. For residential applications, measure the width and height of the window, then lay the film on a flat, clean surface. Cut a piece of film that is at least 1 inch larger than the measured dimensions on three sides. The remaining side should be left slightly longer to allow for adjustments during installation. A utility knife and straight edge should be used to make precise cuts.
For automotive installations, the film should also be trimmed to fit the window. The film is typically applied to the outside of the glass with the paper liner facing out, and the final installation is done on the interior. After the film is cut, it should be wetted thoroughly with the Gila application solution on both sides. A helper can assist in flipping the film over to ensure even coverage.
To remove the clear liner from the film, attach two strips of clear tape to one corner of the film. Press the tape firmly on both sides of the film, then quickly pull the pieces of tape apart to separate the liner. A helper can help hold the film flat while the liner is being peeled away. As the liner is removed, the exposed side of the film should be sprayed with the application solution to prevent it from sticking prematurely.
Applying the Film
With the film prepared and the window surfaces clean, the next step is to apply the film to the glass. Begin by aligning the factory edge of the adhesive side of the film with either the top or one side of the window. Carefully smooth the rest of the film onto the glass using your hands to press it flat. This step requires patience and precision to ensure that the film is applied evenly without wrinkles or air bubbles.
After the film is in place, it should be sprayed thoroughly with the Gila application solution. A squeegee should then be used to remove any excess water and to smooth out the film. Start at the top center of the window, holding the squeegee blade vertically, and slowly drag it to the right, working from the center outward. Stop 2 inches before reaching the edge of the window. Repeat this process, working from the center to the left. This technique helps to eliminate air bubbles and ensures a smooth, even finish.
Once the film is squeegeed, any excess material at the three edges of the window should be trimmed away, leaving a 1/16-inch gap between the edge of the film and the window frame. On the fourth side, a 1/16-inch strip should be cut from the factory edge. This gap is necessary because glass expands and contracts with temperature changes, and the film must accommodate this movement without peeling or warping.
After trimming, the film should be squeegeed again to ensure that any remaining air bubbles are removed. A clean, lint-free cloth can be used to absorb any pockets of water that may remain on the surface. Once the film is properly applied and smoothed, it should be left to cure for 7 to 10 days. During this time, the film may appear cloudy or hazy, which is a normal part of the curing process.
Post-Installation Care and Maintenance
After the film has cured, it is important to follow proper care and maintenance procedures to ensure its longevity and performance. For both residential and automotive applications, Gila application solution or a standard glass cleaner and squeegee can be used to clean the windows. A clean, lint-free cloth should be used to wipe down the surface and dry it thoroughly. Ammonia-based cleaners should not be left on the film for more than one to two minutes, as they can cause damage.
If any mistakes are made during the installation process, the user manual should be consulted for guidance on how to correct them. For automotive applications, it is important to avoid rolling down the windows during the first week to 10 days of curing, as this can dislodge the film or cause it to peel. The curing process is faster in dry, sunny weather and slower in wet, cold conditions.
Conclusion
Installing Gila window film requires careful preparation, attention to detail, and adherence to safety guidelines. By following the recommended steps—cleaning the glass, cutting the film to the correct size, and applying it with precision—users can achieve a professional-looking finish that enhances privacy, reduces glare, and improves energy efficiency. Whether applied to residential windows or automotive glass, Gila window film is a durable and effective solution that, when properly installed and maintained, can provide long-lasting benefits.
