How To Properly Do Windshield Replacement For Your Car

By Donald Watson


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 replacement glass may be obtained from a new window dealer or from a site owned by a wrecker. If you afford one from a wrecker, thoroughly check glass so that you may detect any traces of cracks in it before handing over the money. To ensure its safe arrival at the replacement site, you should cushion it using a blanket or a thick duvet.

After obtaining glass, remove the plastic surrounding side plus the upper moldings correctly. Make sure you do not pry the clips holding them together because the clips are unique to the car. Having the clips on will save you a considerable amount of time but if they are unavailable, you will have to use glue to attach the moldings on the car.

Next in your replacement procedure should be to cut the urethane from the outside between the glass and the pinch weld using a cold knife. This process takes between fifteen minutes to one hour depending on the experience and the tools that are using. The urethane is simply the flexible film that allows the windscreen to move without breaking when stress is applied to it during driving.

Before placing the replacement windscreen, prepare a pinch weld first. It involves brushing away visible dirt and then using plain water to wash away any remaining dirt. After doing so, use razor blade to cut the old urethane in the frame of the windscreen on the car to about 3mm. The rusty areas that remain exposed should be primed.

When making glass ready using the primer, make sure the primer you are using is specifically made to adhere to the specific urethane you will apply. The primer is meant to open up the molecules of the frit band. A frit band is the continuous black thread running around the edge of the glass. Here, glass is basically being prepared to accept the molecules of the urethane. After preparing the glass, attach the molding to it. After doing that, attach the urethane.

Application of the urethane should be done using a caulking gun. This is because the gun helps you to maintain a consistent bead as you apply it. A consistent bead will ensure that there will not be any spaces that will lead to leaks after replacement. The old urethane is the most suitable material to attach your new urethane. However, you should ensure that it is clean and free from oil.

You should then place the glass onto the car. If you are not using mounting block, avoid touching the frit band with your bare hands. It is due to the fact that oil and the filth from your hand will contaminate the glass that has been already been activated. Contamination reduces the efficiency of the urethane. To avoid this use latex hand covering.
