Procedures: How to Keep Rain Out of Broken Car Window

1. Remove the Broken Glass:

If you have broken car windows, the first thing that you need to do is remove the glass from the frame. Next, use a thin object like a flat piece of metal or one of your credit cards and wedge it into the edge of the glass. Do this around all sides of your window until you can pull out most pieces without resistance.

2. Clean the Surface:

After you’ve removed the bulk of the glass from your car, it’s time to clean up the remnants. You can do this using dry cloths or paper towels, which will help prevent water from seeping in on rainy days when you have to use plastic wrap or bags to cover the broken windows temporarily. If you’re using plastic wrap, you can do this before or after you cover the window frame with your chosen material.

3. Cut Your Materials to Size:

If you’re using any materials that are not pre-cut, then it’s time to cut them down into shape. Find something thin and sharp, so it doesn’t damage or scratch up the glass. You may use a pair of scissors or even a knife.

4. Seal Up the Window:

When your materials are cut down to size, it’s time to seal them in and cover up the rubber window seal area. Use duct tape on cardboard and other larger pieces of material if needed for extra support. Ensure that there are no gaps between the window switches and your material so water can’t get in. You’ll need this to keep the rain out of broken car window glass when it’s raining outside.

5. Add a Second Layer Outside:

If you’re using a piece of cardboard to cover up your broken glass window, you’ll need to add another layer outside. This will protect it from getting soaked by rain or snow while keeping it in place from getting blown away. You can do this with more layers of duct tape or any other adhesive material you may already have in your home.

6. Clean up Any Spills or Dirt:

If you’ve got any leftover pieces of glass around, then make sure that you clean up any spills or dirt on the frames. Leaving any around will allow water or moisture to seep through and get inside your car. So instead, use a damp rag or paper towel to clean up as much of it as possible before starting.

7. Give Time To Dry up:

After cleaning everything off, wait about an hour or so to let the materials around the frameless window glass dry up. Make sure that no debris or water gets on them during this time because it will cause your project to fail, and you’ll have to start all over again.

8. Test Your Card Window:

After waiting for about an hour, get back in your car and test whether the material works at keeping out water. Lightly tap on the window and see if any splashes occur. If none do, you know you’ve done a good job!

What Can You Use To Cover Your broken Card Window?

1. Transparent Plastic Bag:

You can cover your broken car window with a plastic transparent bag. You may already have some in your trunk for grocery shopping. If not, you can buy a package of clear, high-density plastic trash bags at any store that sells groceries or products for camping supplies and outdoor activities.

2. Plastic Wrap:

Another way to keep the rain out of broken car rear windows is by using plastic wrap. Take some and pull it tightly around the interior of your car window seal. The type you use in the kitchen would also work fine for this purpose.

3. Duct Tape:

This one is probably the easiest to do so without any extra supplies or money invested into it. Just take the duct masking tape and cover the entire broken side window exterior of the car. Ensure that you leave no gaps in between to ensure that water doesn’t get through. The layers of duct tape will work as a temporary window cover for the car.

4. Card Board:

If none of these options work out for you, then another way to keep the rain out of broken car windows is by placing a piece of cardboard over the glass window, which will work as a temporary car window cover. Then, use duct tape to secure it on top of your car’s rear window replacement and keep rain from entering your vehicle.

5. Crash Wrap:

A crash wrap is a high-quality self-adhering film that’s made to fit any size or shape of the glass. Insurance companies and government regulators are currently using it worldwide to help prevent the spread of infection in hospitals. This material doesn’t allow water and moisture to get through but lets in light so that you don’t feel like you are in a dark room. In addition, it’s very easy to use because it will stick on any glass surface that is clean and free from dirt, dust, or debris.

Some Other Tips To Consider

If you think placing the items mentioned above might not be enough to keep the rain out of broken car windows, you can always consider taking these extra actions to keep the rain out of the broken, stuck car windows.

  • If you have spare parts in your trunk or vehicle, consider using them to keep the rain out of broken car windows and block water from getting inside. This includes cardboard boxes, blankets, foam sheets, and even towels made from cotton or wool.
  • You can also pour hot glue around the broken window seal area. Again, avoid anything made with cold glue since it will melt when it comes into contact with water or moisture. Hot glue can withstand the rain, snow, and other elements, but make sure to place small pieces of cardboard in between before doing so to prevent any melting onto your glass.
  • Make sure to position your material directly in the middle of a broken car window to cover more area. This will also guard against any water from getting back inside after coming through your broken car glass.
  • If you use a towel or blanket made of cotton or wool, make sure that it’s the dry version, not the damp one. A damp material will only work when it’s clean and new, but once it gets wet, it doesn’t serve its purpose anymore.
  • When you’re done cleaning up and covering up the area, make sure to let it sit overnight before removing it. This will ensure that everything is nice and dry before you take any objects off. Leaving this overnight also lets you breathe easy, knowing that your car will be protected against water or moisture when you wake up in the morning!
