When it comes to finishing drywall, sanding is an essential step in achieving a smooth and flawless finish. The right sandpaper grit is crucial in achieving the desired result. So, what grit sandpaper should you use for the drywall joint compound? Let's explore.

First, let's define drywall joint compound. It's a material used to fill and smooth the seams between drywall panels, creating a seamless surface. Once the joint compound has dried, it needs to be sanded to achieve a smooth surface.

The grit of sandpaper you should use for drywall joint compound depends on the stage of sanding you're in. If you're using sandpaper for the first time to sand down the rough edges of the joint compound, you should start with a coarse grit of around 100-120. This grit level will help you to remove any excess joint compound quickly.

As you continue sanding, you can switch to finer grit sandpaper, such as 150-180 grit. This will help smooth out any rough spots or bumps left behind by the initial sanding.

Finally, if you want a perfectly smooth and polished finish, you can finish up with a very fine sandpaper grit of around 220-240. This final sanding will create a smooth, glass-like finish.

It's essential to note that using too coarse sandpaper or skipping grit levels can result in uneven sanding, leaving behind noticeable scratches and rough spots. Always sand in a circular motion, apply light pressure, and make sure to clean up any dust or debris before painting.

In conclusion, when sanding drywall joint compound, start with a coarse grit of around 100-120 and work your way up to a finer grit of 150-180 before finishing with a very fine grit of 220-240. With the right sandpaper grit and technique, you can achieve a smooth and flawless finish on your drywall project.
