Grinding and polishing glass: removing scratches and dings

Glass is one of the most popular and versatile materials used in a variety of applications, from window panes and car windscreens to furniture and decorative items. However, over time, glass can be subjected to mechanical stresses such as scratches and scale that can significantly affect its clarity and appearance.

In such cases, glass grinding and polishing become indispensable procedures to restore its former beauty and functionality. Glass polishing aims at removing deep defects, scratches and scale, while polishing gives the glass a smooth and shiny surface.
The glass grinding process begins with the use of specialised abrasive tools and materials. Coarse abrasives are used to remove deep scratches and scale, while controlling the pressure and speed of grinding to avoid damage to the glass. Gradually, finer abrasives are used to smooth the surface and remove any remaining irregularities. POLIRO craftsmen, when removing deep scale, start grinding with silicon carbide abrasive wheels with P40 grit, called grit wheels. This is a serious process that requires professional skills and knowledge of abrasives. If you have some familiarity with the different types of abrasives, you realise how serious it is.

After the grinding process is completed, the glass is polished. Here we use our own polishing compounds: HEAVY CRYSTAL or POLIRO M8, which give the glass a smooth and shiny surface. Polishing also helps to eliminate small scratches and leave the glass without visible traces of treatment.
It is important to note that glass grinding and polishing are complex processes that require professional skills. Improper use of tools and materials can lead to further damage to the glass: loss of transparency and distortion. Therefore, for optimal results, we recommend that you contact strictly experienced professionals.
  • 1
    Restoring Appearance:
    Glass restoration can remove scratches, scale and other defects, restoring glass to its attractive and flawless appearance. This is especially important for car windows, building windows or glass surfaces in interiors that may be susceptible to damage.
  • 2
    Improving Transparency:
    Scuffs and water stone on glass can significantly reduce its transparency, affecting the quality of the view or light transmission. Restoration can remove these defects, restoring the transparency of the glass and improving functionality.

    Economic Benefit:
    Instead of replacing the entire damaged glass, restoration offers a more cost-effective solution. It allows the glass to be restored to its original condition, avoiding the cost of new glass and its installation. This is especially true for large surfaces such as building windows or facades.

    Increased service life:
    Glass restoration helps to extend the life of glass by removing surface defects. Scratches and scale can be a source of further glass deterioration, so their timely removal helps to preserve its integrity and durability over time.

    Environmental Friendliness:
    Glass restoration is a more environmentally friendly option compared to glass replacement. It preserves the glass and prevents it from being released into the environment. This is important given the growing problem with waste and environmental challenges.

Why are many people unaware of the possibility of removing serious defects from glass?

Assumed range of factors:
  • Lack of awareness:
    Information about glass restoration methods and options may not be widely available. Many people are simply not aware that there are specialised procedures and techniques to remove deep scratches and scale from glass.
  • Limited access to specialists:
    Not all regions have professional craftsmen who specialise in glass restoration. This can create barriers for people who want to restore damaged glass, as they have to look for specialists in other cities or regions.
  • Myths and prejudices:
    100% There are myths or preconceptions about glass restoration that stretch back to the 90's. Some people may believe that deep scratches and dings cannot be completely removed, or that the restoration process may damage the glass further. This can scare people away from the idea of contacting restoration professionals.
  • Glass replacement preferred:
    In some cases, people may prefer glass replacement over glass restoration. This may be due to a lack of awareness of restoration options or simply a preference to get new glass instead of restoring damaged glass.
