Sandpaper is an abrasive that removes material from a surface by abrasion. Sandpaper can be made of paper, cloth, or leather with an abrasive such as sand, grits, or emery applied to it.
The most common use is to smooth down rough surfaces like wood, plasterboard, or metal. The sandpaper can be used with a sanding block or block sander, but also with an electric orbital sander.
What are the Different Types of Sandpaper by Materials?
Keep your tools and surfaces in check with the right sandpaper. Harfington has a variety of different sandpapers that are perfect for tackling any job, from fine smoothing to heavy-duty fastening.
Types of sandpaper are classified by materials and our selection of sandpaper includes aluminum oxide, ceramic, flint, garnet, and silicon carbide to meet your wide needs.
Aluminum oxide is the most common type of abrasive material. It is a tougher and more durable abrasive, which is why it is used in metal-working applications that require the material to have a high level of strength.
Silicon carbide is harder and sharper and is therefore used for applications involving glass and other non-metallic materials.
Alumina containing zirconium and alumina minerals are often used for smoothing cases where extremely strong abrasives are required, such as in foundries.
Expensive and extremely hard minerals such as diamond or cubic boron nitride are limited to special polishing processes.
What are the Different Types of Sandpaper Grit?
Then coarse (60 – 80Grit) sandpaper is coarse enough to take off old paint smoothly yet won’t damage your floor the way that steel wool might.
It is safe for use on all types of surfaces and has a low abrasion rate. It can also be used for more than just removing old polish – it’s perfect for the preliminary treatment of old floors.
The medium sandpaper comes with 100 – 150 grit. This type of sandpaper is generally used for bare wood surfaces. A final sanding with 150-grit paper is commonly recommended for wood surfaces.
While sanding surfaces between coats of paint, fine sandpaper does its wonder. This type of sandpaper features 180-220 grit.
Ultra-fine sandpaper is excellent for sanding finishes or wood. These sandpapers are usually 320 grit or higher, meaning they remove material more easily than other grits.
