Broken windows in your car may lead to dangerous driving conditions which may cause occurrence of road accidents. That is why you should promptly carry out windshield replacement as soon as it gets broken. Regardless of whether or not you have done a previous replacement, installing new glass panes to your car using the correct procedure is a way to get you back to the road in good time.

The glass pane that you intend to install can be bought from a dealer. It can also be got from a yard belonging to a wrecker in the city. If it is from a wrecker, ensure that you thoroughly scrutinize it for any cracks and chips before you finally offer money. You should cushion it so as to avoid any damages while the good is on transit.

You are then supposed to carefully remove the plastic surround side and the molding covering. You should cautiously go about this step so as not pry the clips that are holding them on. These clips are important because they are specific to the type of car. They help you save a lot of time but in case you cannot afford them, you will need to glue the moldings onto the car manually.

Using cold knife, cut the urethane between the windscreen and pinch weld. The experience and tools used affects the time consumed during the replacement process. It should normally take between a quarter an hour to an hour. The urethane is the flexible but extremely strong film that prevents glass from breaking when it under stress while driving.

Before putting glass into place, make the pinch weld ready first. You should do this by brushing away the dirt and oil that may have smeared on it and then later wiping it using plain water. To effectively trim off the old urethane to the required height of three millimeters use a sharp razor blade. If there are still areas covered with dust, they should be primed.

Prepare the glass with a primer that is specifically matched to urethane adhesive. The role of the primer here is to open the molecules of the frit band, the black band surrounding the perimeter of the windshield. The pane is made to accept the particles of the urethane. After the glass is made ready, first attach the molding to it after which the urethane should be attached.

Using an electric caulking gun, apply the urethane to the glass. The electric gun ensure a consistent bead thereby avoiding leakages. It is good to know that the old urethane is the best thing that the new urethane will properly adhere to. This old urethane should be free from dirt, oil or other contaminants. You should ensure that the wind will not recontaminate the pinch weld before the adhesive urethane is applied.

You should then carefully place the windscreen to your car. If you are not using the mounting block, make sure that you wear a pair of latex gloves. They will ensure you do not touch the glass with your bare hands as doing this will contaminate the activated glass and will reduce the adhesiveness of the activator.
