What is a sanding disc?

A sanding disc also known as sandpaper is a type of round paper or cloth with abrasive material stuck to it.

Sanding discs are perfect for sanding flat surfaces and removing paint, varnish, or other coatings from the areas of wood you want to resurface.

They can be used wet or dry depending on the surface you’re working with. The abrasive material in these discs is usually silicon carbide grit which is one of the toughest materials that can be found in sandpaper.

The most common types of sandpaper are coarse, medium, and fine grits but there are also options for extra-coarse and ultra-fine grades as well. Sanding discs vary in size according to how much material they will remove per pass – larger sizes mean fewer passes needed to get your desired result.

Types of Sanding Disc

There are mainly two types of sanding discs. 

1.Adhesive-backed disc

Adhesive-backed sanding discs are attached to the sander with glue on the back. They are easy to use & easy to change. Still, they are being used less frequently as hoop & loop disc provides more advantage.

2.Hook & Loop disc

These are very similar to velcro. Hook & loop are more popular nowadays & they’ve replaced adhesive-backed discs. Although they are a bit expensive than the other sanding discs. But the price is worth it. They provide several advantages over the older sandpapers. These are easy to change, flexible, sustainable.

Type of Sanding Grits

1.Coarse Grit

Coarse grit is normally used at the beginning of a project to remove a large amount of material.

2.Fine Grit.

Fine grits give a smooth finish to the project. It is also used on sanding the edges of a surface.

You need to use several sanding discs to finish your project. Start with coarse grit and work your way up to finer grit for a smooth finish. Generally, 40 to 60 coarse grit is good to be started with. Use finer grits like 200 to 220 to leave a smooth finish.

You can reuse a disc several times. After finishing your project, put off the disc, keep it in a secured place & use it again when needed.
