What is grit in polishing compounds? In short, this is the measurement of coarseness to the fineness of the polishing compound.
There are dozens of different polishing compounds available, and they all have different uses, side effects, and grits – it’s enough to make your head spin. If you’re just starting on your polishing journey, it can be hard to know which compound to use and what kind of results you can expect from each one. In that case, a polishing compound grit chart can solve the trouble.
To help ease the confusion, we’ve put together this handy chart with everything you need to know about polishing compound grit, including information on each of the most popular types of compound used in the industry today.
Polishing Compound Grit Chart to Find the Right
If you’re new to polishing or just need a refresher, it’s important to know the basics of grit sizes. A grit chart is a great way to understand the different levels of coarseness and fineness in polishing compounds.
In general, the higher the number on the chart, the finer the compound. The lower the number, the coarser the compound. The chart is as follows:
Polishing Compound | Mesh | Micron | Grit | Application |
Blue | 0-2 | 1 | 14000 | Final polishing |
Green | 2-4 | 3 | 8000 | Final polishing |
Yellow | 4-6 | 6 | 3000 | Lapping and pre-polishing |
Red | 6-12 | 9 | 1800 | Lapping and pre-polishing |
Brown | 10-20 | 15 | 1200 | Lapping and pre-polishing |
Mahogany | 20-40 | 30 | 600 | Rapid Stock Removal |
Purple | 40-50 | 45 | 325 | Rapid Stock Removal |
Orange | 50-80 | 60 | 270 | Rapid Stock Removal |
White | 120-160 | 150 | 100 | Rapid Stock Removal |
There are a few different grades of polishing compounds, and each one is designed for a specific purpose. The most common grades are-
- Coarse grades of the polishing compound have big particles, but they’re not as rough as sandpaper or steel wool.
- Medium grades of polish cut deeper into the surface than coarse grades do, creating a finer finish.
- Fine grades of polish are used to create an even finer finish.
- Extra-fine grades can be used to remove scratches that show up in glossy finishes after you apply paint, varnish, lacquer, or wax.
Polishing compounds are graded based on how fine they are and how abrasive they are. Coarse grades of the polishing compound have big particles, but they’re not as rough as sandpaper or steel wool.
Frequently Asked Questions (FAQs)
What Is The Grit Of A Polishing Compound?
The grit of a polishing compound is a measure of the coarseness of the compound. The higher the grit number, the finer the compound. The most common grits used for polishing are #600, #1200, and #4000. When choosing a polishing compound, you need to consider the type of metal you’re working with, as well as the desired results.
What Is The Difference Between Red And Green Polishing Compounds?
While the red polishing compound grit is 1800, the green polishing compound grit is 8000. The red polishing compound is designed for use on ferrous metals, while the green polishing compound is meant for use on non-ferrous metals. The main difference between the two is the abrasiveness; the red polishing compound is much more abrasive than green. This means that it will remove more material from the surface being polished, but it can also cause more damage if not used properly.
What Polishing Compound Is Most Abrasive?
The black polishing compound is the most abrasive. If you’re looking to remove heavy scratches or buff out a tough surface, a black polishing compound is your best bet. But be warned – it can also leave behind some pretty intense swirl marks.
What Grit Is A Red Polishing Compound?
Red polishing compound is a medium-grit compound, usually around 6.5 microns or 1800 grit. This compound is designed for general-purpose polishing and can be used on a variety of materials.
What Grit Is A Blue Polishing Compound?
If you’re using a blue polishing compound, you’re likely working with a product that has a grit of 14000. This means that the compound is composed of very fine particles that will produce a high-gloss finish.
What Grit Is A Black Polishing Compound?
Black polishing compound grit has large particles and is therefore considered a coarse compound of 320 grit and 400 grit.
What Grit Is A Brown Polishing Compound
The Brown polishing compound has a grit of 1200. This means that it is suitable for use on metals that are not very scratched or corroded.
Conclusion
To wrap it up we want to say that here are a few things to keep in mind when using a polishing compound grit chart. First, the grit size is important, but so is the type of compound you’re using. Second, always test the compound on a small area first to make sure it’s compatible with your project. Third, be sure to use enough pressure when applying the compound – too little, and you won’t see results; too much and you could damage your project.
