How to Choose The Right Sandpaper Grit? Sandpaper is a sheet of thick paper with an abrasive mixture glued to the side. It is used in various industries, including woodworking. Sandpaper is used for preparing walls for painting, preparing exterior paint, finishing wood, joinery, sanding metal, and more. While many people are familiar with traditional sandpaper uses such as those just mentioned, this popular abrasive also has several exciting and unique uses. Read on to find out more about sandpaper and some unconventional uses.
Unconventional use of sandpaper
As promised, we’ll discuss some fun and unconventional ways to use sandpaper that many people don’t know about. For example, you can sand the soles of your shoes for better traction. This is useful for anyone working on slippery roads or for a better grip on ice and snow. What about those brine jars that never seem to open? A small square of sandpaper will give you the extra grip you need to remove the top in no time! You can also use sandpaper to remove rust from tools, scissors, and other metal items.
Sandpaper is a unique and handy tool that is ideal for smoothing surfaces on various types of materials. The abrasive mixture can be composed of multiple elements such as aluminum oxide or silicon carbide. But grains are specifically made from sand, stone, gravel, and even metal. There are several types of sandpaper with varying grain sizes. Grit indicates how fine or coarse the sandpaper or surface should be. Smaller numbers represent larger grains, and higher numbers represent smaller grains.
Sandpaper is mostly used for:
• Sanding of walls before painting.
• Repair of wooden floors.
• Sand the floors before applying the sealant.
• Removing grout stains.
• Removing stains from wooden floors.
• Metal polishing
• Rust removal
• Carpentry works
• Carpentry works
• And more
What should you know when buying sandpaper?
Whether you are buying 120 grit sandpaper for your project or any other, you should know that the quality of the grit you buy will significantly impact the outcome of your project. The number corresponding to the grain size of the grit is one of its most essential characteristics. So why is this important, and what does it tell you? The Grit Number tells customers about the roughness of the sandpaper, which is very important to know when looking for a disc for a particular application. And if you want to improve the results of your project, it is recommended that you use different grit sandpaper discs throughout the project. Using discs with one-grain size may not give good results. The result you get at the end of the project also depends on the application in which you are using the disk.
All sandpaper can be divided into six categories based on the number of abrasive particles (grits) per square inch.
The categories are as follows:
Course – Abrasives contain 40 to 60 grains. They are best suited for challenging woodworking and finishing jobs.
Medium – Medium 80-120 grit is used to remove minor stains and imperfections and smooth wood surfaces.
Fine – fine sandpaper holds 150-180 grit. They are usually used for the final smoothing before applying the topcoat.
Very fine – very fine abrasive contains 220 to 240 grains. They are best used for sanding wood between stains and seals.
Extra fine – 280 to 320 grains. Between finished layers, ultra-fine paper removes dust spots and similar small defects.
Super Fine – It is the finest sandpaper available in 360 grit or better. They are usually used in the final stages of woodworking work.
There are various specifications of sanding grit to help you choose the right one for your project. The diameter reflects its size, and the number of grains indicates the roughness of the sandpaper. In addition, other characteristics reflect the specific tasks in which the disk can be used. Some of these include the abrasive, the type of disc, and the absence or presence of holes, to name a few.
