How to Repair a Crack in a Mirror?

To begin, we must understand that a mirror is simply a sheet of glass with a small layer of aluminium or silver cemented by electrolysis. The surface is highly reflective, but because it is made of glass, it is quite fragile.

If not corrected, the cracks in the mirrors might expand and damage the entire surface. As a result, it is critical to address the issue before it spreads like wildfire.

Two approaches are available for mending a mirror. And each one is used in accordance with the break. Furthermore, it necessitates the usage of various materials.

Chalk should be used to fill the crack

The first approach for repairing a mirror crack is to fill the crack with chalk. So that the crack does not continue to expand. To avoid the existence of residues and dust, the fracture must be properly cleaned before filling. Because glass splinters are exceedingly sharp, special care must be used during the cleaning process. The crack will then be filled with chalk and sanded with abrasive paper after it has dried.

Make use of a resin-based repair kit

Whereas if a crack in the mirror is large or in a central location, a basic repair kit for resin-based mirrors can be used. The equipment is available in specialised stores and is designed specifically for glass repair. This procedure is incredibly effective and allows for practically undetectable repairs. Resins are utilised in windscreen repair and work well on splinters and cracks that are less than 30 cm long.

Fill the Crack with Resin

After cleaning the crack, inject the resin into it with a syringe while using the stabiliser. Wait for the resin to dry before covering it with the film. Make sure to fill the crack evenly. After the laying time has passed, just remove the film and clean it with a cloth. At the completion of the treatment, your mirror will be brand new.
