And lastly, you need to carefully clean the glasses before and after the procedure for smooth and effective installation process and clear-cut visibility, respectively.
Now that you know all the necessary tools required to take on the windscreen replacement (Perth) task, let us discuss some precautionary steps that you should take before starting.
Necessary precautions to take before the windscreen replacement process
First of, you will need to purchase a new windscreen from an original parts dealer or a reputable after market distributor whose glass meets the vehicle manufacturer’s safety standards. Since, it is important to eliminate the risks of purchasing a defected or second-hand windscreen.
Once you have purchased the required windscreen, you can start the installation process. Before you do keep these instructions in mind:
- Firstly, you will need to have it cleaned thoroughly.
- Take extra care and precaution and do the cleaning as gently a possible.
- Use a safe and renowned window cleaning brand or contact your local window screen replacement specialist for advice. Don’t risk it!
- Make sure that the outer black ceramic is free from dirt, dust and grease.
- Once cleaned, you will need a suitable primer to install the window screen.
- Make sure to use a lint free cloth for it.
- Selecting the primer is crucial as it needs to be specific to the urethane. So, it is better to consult a professional. Avoid taking unnecessary risks. It is just a matter of few bucks!
- After spreading the primer, make sure the area is not touched with your hands as oil or other residues from your hand may affect the effect of the urethane from adhering to the glass tightly.
- After the windscreen has been cleaned and primed, you will need to mould the glass.
- However, ensure that you are wearing powder free latex gloves to do the task to avoid the risk of loosening its fastening.
The process of removing the current windscreen from the vehicle
Let us directly hit the topic now!
- First, you will have to remove all the surrounding moulds from the bottom plenum chamber and windscreen wipers. Once, you have removed all the mouldings, use a cold knife or a “drag knife” as called by some to cut the existing urethane bonding from all sides of the windscreen. After breaking the bond between glass and urethane, use an Olfa or BTB knife to cut through the lower section of the glass from the urethane from inside of the car.
- After loosening the bond, use a suction pump (very important) to lift out the windscreen. It can be very heavy, so for safety precaution, two people are preferable. Then cut through the old urethane from the body of the vehicles using a sharp knife preferably olfa or BTB. However, you need to leave 1-2mm of urethane attached to the body.
- Clean the surface area of the car successfully removing all the dust, dirt and grease from it. Pick the suitable prime as discussed above and apply the primer. However, make sure that all the scratches and exposed metal surfaces are properly covered. Since, this will help prevent the body from rusting that might happen later on.
- You have to use a large caulking gun to apply the certified automotive urethane to the primed glass surface area. However, it needs to be done with lot of care to keep the bead at the same height as the windscreen, leaving no gap in it.
- You need suction pump to attach the windscreen to the vehicle. Call another person to help you carry the screen and place it into the correct position. You have to ensure that a good contact between the body surface and urethane has been made.
- Once in the correct position, gently press the windscreen down and apply tapes to seal it from any unnecessary movement. Re-fit all the necessary mouldings around the plenum chamber and windscreen wipers and clean the outside of the windscreen well enough. Keep the windows of the vehicles open while closing the door or else, it might put pressure on your urethane as the primer will still be wet and could cause the seal from breaking out or creating a hole from the air pressure.
Wait for a certain amount of time, at least an hour or more, for which it is best to contact a windscreen replacement and repairs (Perth) specialist, before removing the tapes from the windscreen and you are good to go!
