How to Repair a Broken Window
Broken window glass could be caused by a hurricane or a child kicking the ball. It can lead to further problems such as drafts or water seepage which can increase your energy bills.
There are many ways to repair the crack depending on the size of the crack. Here are some suggestions to think about:

Tape
A tape that's old-fashioned can be used to temporarily repair cracks in your windows. It's cheap, easy to use and works well. Make sure you cover both sides of the crack so that it is as secure as it can be. This will prevent air from entering which could cause further damage to the glass and shatters within the window. Clear tape is an excellent option as it looks better than duct tap and doesn't leave sticky residue when removed.
You can also purchase special adhesive tape in most hardware stores. It is available in two x 30' lengths and creates an invisible patch that stops the crack or tear from spreading further. It is ideal for boat enclosure windows tent or RV vinyl windows, and even car windows with soft tops. It is easy to use and requires no specialized tools or skills. Just cut the correct size, then remove the release paper, and apply it. It is UV and saltwater resistant and made from an extremely durable material that is able to withstand harsh environments. This will save you lots of money by not needing to buy a complete window replacement.
Super Glue
Super glue can be used to repair chips or cracks in glass. These adhesives bond to hydroxyl ions on the glass's surface, forming an extremely strong hold in just a few seconds. Cyanoacrylate glues can also be used for affixing metal, wood and ceramic to glass since they can withstand moisture and high temperatures. If you have a big project to complete, however you may want to consider using epoxy or silicone glues for a more long-lasting hold and faster drying.
Before applying any glue to a window that has been damaged, it's important to prepare the surface. You'll want to remove any debris that may be present and make sure that both surfaces are clean and dry. It is also an excellent idea to roughen the surface, especially if it is extremely smooth. A slight sanding gives the adhesive a larger surface to adhere to, resulting in a better bond.
When you're ready for the actual repairs, it's crucial to select a good glue that has been specifically designed for glass. This will ensure the glue is safe and won't leave any unattractive marks or fingerprints. If you can, select an adhesive that is clear and will be clear once it has dried. Avoid glues that swell when they're drying, as they can increase the risk of cracked glass.
You'll also have to think about how the glass will be used. Super glue is fine for glass that will be kept inside and won't be under much stress. However, if the glass is going to be part of a windshield it is advisable to use an adhesive that is weatherproof.
Super glues generally take few seconds to bond but they can have different cure times. Some require chemical accelerators to speed up the process, and it is important to follow the directions of the manufacturer carefully. It's a good idea to work in an area that's well ventilated and has windows that are open to allow more air flow. This will help the glue dry more quickly. Additionally you can always utilize a fan to boost the air flow around your work area, allowing it to dry even more quickly.
Glass Repair Film

Anyone can install it, even if they are not a skilled tradesperson. It's easy to do and quick. It is much cheaper than a traditional window glass board and keeps rain out and heat in.

There are several different types of safety film that are available, depending on the type and severity of the damage. Gray safety film is recommended for star breaks, whereas amber safety films are best for bullseye breaks as well as other breaks that have lots of small cracks. The films should be applied to clean glass that is wet and it is recommended to employ a squeegee made of polyethylene with soap solution to apply the film.

Paint
It is essential to paint a window thoroughly. This will make the appearance of the paint nicer and allow it to adhere better. Before you begin, ensure that the window is clean and scraped to remove any bits of paint or wood that are sagging or rotten. Take out all hardware, such as handles and latches. In the end, you'll need to sand the area that is going to be painted. This will give you a surface that is smooth so that the primer and paint can join.
It is important to protect the surrounding areas of the window with plastic sheeting and painters tape. This will stop paint from accumulating on areas that are not intended to be painted. Green frog tape is the best to do this since it forms an uncluttered line that is easy to remove. Painters tape is a great option for any edges that are located near the walls.
Once the window is protected, you can begin painting. You'll need to apply several coats of primer, and let each one dry before moving on. After priming the area, you can lightly sand the entire surface using fine-grit sandpaper. This will help to make the surface smooth for the next coat of paint and will also help in removing any dust that may have accumulated.
If you are using oil or acrylic base paints and primers then you will need to wait for them to completely dry before you begin painting. window repair could take up to one day, based on the brand you're using.
Once the primer and paint are dry, it's now time to paint. It is recommended to paint from the inside out by painting rails (horizontals) before stiles (verticals). This will help keep drips from accumulating on the glass. Also, make sure you keep a moist cloth handy to wipe away any drips of paint as soon as they occur.
