Chip Repair

What happens when a stone hits your windscreen?

Your windscreen is made up of two sheets of glass and one poly vinyl (plastic) sheet. The poly vinyl sheet is sandwiched between the two sheets of glass. When a stone hits your screen, usually a small chip occurs which creates an air pocket. This air pocket is between the outer glass layer and poly vinyl sheet. It is this air that needs to be removed.

Did you know... that by ignoring that little chip, you could permanently damage that area of the screen making it unrepairable.

For best results, the chip needs to be repaired as soon as possible and the damaged area must not exceed the size of a five pence piece.

How do we repair the chip?

We first drill out the chipped glass, a bit like a dentist would drill out a tooth ready for a filling. This cleans out the area ready for the filling process. We then attach a repair bridge to the screen and begin to turn a screw which injects the repair resin into the cavity. When we do this it causes a vacuum in the cavity and when the screw is unscrewed it pulls the air out to the top.

This process is repeated until all the air has been removed and all the fresh resin has been injected. Once this process is complete, then a clear pit fill resin is placed on top of the repaired chip and treated with an ultra violet lamp until the resin has set rock hard.

We then scrape off the excess resin and polish the repaired area with a pit fill polish. The repair is now complete and is as hard as the existing screen.
