Polishing glass with GOI paste

The history of glass has more than 5.5 thousand years. Currently, it accompanies us everywhere - from the glass of our wristwatches to the windows of our car. However, over time, the glass is covered with scratches, cloudy. A universal agent for polishing and restoring the aesthetic appearance of such a material is GOI paste. It is used for processing not only glass, but also plastic, plastic, mirrors, even metals, including precious ones. How the glass is polished with GOI paste - we'll discuss this in detail in this article.

What is the GOI paste?

GOI is an abbreviation, which stands for the State Optical Institute, where in 30 years this paste was developed. It is available in the form of solid bars, mostly green. It is based on chromium oxide.

This tool was developed to repair damaged material, protect it from external influences, to improve reflective qualities. It allows you to polish mirror or glass surfaces. The mass applied to the scratched, damaged glass fills small chips, restores the integrity of the structure.

The main parameter by which the views of this tool are divided is the granularity. GOI paste is produced in four variations, each of which is affixed with the number:

• No. 1 and No. 2 - fine crumb that allows polishing of even surfaces to maximum gloss.
• No. 3 is suitable for polishing steel, another metal.
• №4 is the coarsest paste, suitable for removing scratches, eliminating noticeable abrasions.

Polishing paste GOI

Before you start directly polishing the glass paste GOI, you need to do the following:

1. The product itself is quite hard, so before applying it on the fabric, you need to dilute it. To do this, you need a few drops of machine oil, after using which produces a liquid consistency.
2. To maximize the effect, first clean the object of dust and dirt.
3. Prepare the necessary tools. The harder and coarser the object, the rougher the tool should be. For the treatment of glass, it is better to use a flannel cloth. If it is a machine glass, then it is better to take a felt disk.

How to polish glass with GOI paste?

• Separate a piece of solid and apply a few drops of engine oil to it. Mix the resulting mixture thoroughly and apply to a rag or polishing disc.

Important! Experts do not recommend applying the product to the polishing object itself - this can worsen the result.

• Wipe the surface for a few minutes. Do not press very hard to not damage the glass.

Important! To polish the glass on the clock or on mobile gadgets, paste # 2 is suitable.

• If the scratches are shallow and the task is only to gloss the surface, then you can cope with this task without any additional devices. And you can use a drill with a special nozzle or grinder to speed up the process. Nozzle is made of felt. It can be used without a drill, when working manually.

Important! All, of course, depends on the amount of work. It will be problematic to handle the windshield of the machine manually and it will take too long, without tools it is indispensable. But the glass on the watch is easy to polish and manually.

• In the process, it is necessary to monitor the heating of the glass, because if it overheats, it may burst.
• The surface to be treated must be regularly wetted with water, otherwise we will get an unsatisfactory result. The result depends on the volume of the liquid and the agent itself.

Important! Too much water will wash away the polishing agent and the abrasive particles will not be able to touch tightly to the glass. If too little water is obtained, it is not a mirror image, but a matte surface.

Grinding or polishing?

In some cases, when the damage is more noticeable, glass polishing is not enough. In these cases grinding is carried out. Grinding is a rough method when leveling the surface with abrasive materials, removing a certain layer. Grinding is used to clean deep scratches. To do this, use the most granular paste number 4.

Manually handle this case will not be easy. This is a longer process, which requires accuracy and patience. After that, the surface looks matte. To smooth it after rough processing, polishing with fine-grained abrasive is carried out. In this case, polishing is the next stage of processing after grinding and is carried out with fine-grained paste No. 1 or No. 2.

That's all the wisdom that you needed to know in order to perfectly polish the glass paste GOI with your own hands. Good luck!
