What Is Sandpaper?

Sandpaper is a handy tool when it comes to woodworking. It can be used for sanding finishes, removing old paint or rust, and even stripping off varnish and glue residue. You can save on sandpaper through coupons.

Sandpaper Grit

It’s vital that you know how many different types of grits there are and what each one does before using your sandpaper. Grit refers to the size of particles in the paper which determines how aggressive it will feel during use. It also determines its number designation (with more significant numbers denoting smaller abrasive particles). 

The more coarse the grit, the rougher feeling like scratching against the skin. In comparison, finer grit means smoother textures on skin surfaces such as glass windows or car body panels. Also, in mind that bigger-sized chips or particles remove material faster than smaller ones. You can check for deals on finer grit sandpaper for savings.

How Is Sandpaper Graded?

Sandpaper is graded by the number of sand grains per square inch. The lower the grit or coarseness, the more coarse particles are in each sheet. It means it takes less time to remove the material with a lower grit but leaves behind a rougher surface and will require more sanding afterward to clean up marks from using an ordinary grit paper. Coarser papers can be used when you need a shorter process time because they cut through wood faster than finer ones.

How To Choose Sandpaper Grit?

Choosing the correct sandpaper grit for your project is essential. Here are three things you need to know about choosing a specific type of sandpaper grit. How it works, what kind of projects it’s best for, and which ones will help make your woodwork shine like new! 

  • Sandpapers come in different sizes, weights, thicknesses, and forms (sheets or discs), but their grain size can categorize them. The coarsest grains can hardly be seen with the naked eye. 
  • These consistencies remove material very quickly without leaving any marks behind on the surface that gets worked upon. Coarse-grit papers work well on surfaces where material removal needs to occur soon, as the initial shaping of stock. Check for discounts on coarse-grit papers for savings.
  • Grit size is measure of the number of particles per square inch (PPI), but you can think about them as if they were sandpaper nails. For example, 100 grit is coarse, and 400-600 would be very fine. 

Coarse Grit Paper

The coarser types take out huge chunks at once. It will create an irregular surface area that’s great to work with when heavy-duty materials need to get removed from a piece of wood or metal. Coarse papers have a lot more open space between their grains than finer ones do. 

It means that there is room for less dirt and dust build-up during use! It makes it easy to keep your workspace clean while using these soiled sheets because any mess won’t get stuck in between the sandpaper’s pores.

Fine Grit Papers

In contrast, more refined pieces of sandpaper are ideal for those who want to achieve a smooth finish without having any marks left behind from coarse sandpapers or metal scrapers. A lot of people will use these kinds on wood surfaces that need to be prepped for finishing. 

They’re often used as a stepping stone before moving onto finer grades and polishing materials! The best thing about fine grit papers is that you don’t have to worry about scratching up your edges with them.
