When you're spackling a wall, it's important to know what grit sandpaper to use. Sandpaper is used to smooth out the spackling compound and create an even surface. Choosing the right grit sandpaper can make a big difference in the final result of your project. In this article, we'll discuss what grit sandpaper is best for spackling and why.

What is Spackling?

Spackling is a paste-like material used to fill holes and cracks in walls, ceilings, and other surfaces. It's made from gypsum powder, water, and glue, and dries quickly. Once dry, spackling can be sanded to create a smooth, even surface that can be painted over.

What Grit Sandpaper To Use for Spackling?

The grit of sandpaper you should use for spackling depends on the texture of the wall or surface you're working on. In general, it's best to start with coarse-grit sandpaper, such as 80-grit or 100-grit, to remove excess spackling and create a smooth surface. As you progress to finer grits, such as 120-grit or 150-grit, you'll create a smoother finish.

If you're spackling a small hole or crack, you can start with fine-grit sandpaper, such as 220-grit, to avoid damaging the surrounding area. It's always best to start with a lower grit and work your way up to finer grits as needed.

Tips for Sanding Spackling

When sanding spackling, it's important to use light pressure and move the sandpaper in a circular motion. This will help avoid creating scratches or uneven spots on the surface. It's also important to change the sandpaper frequently to ensure it remains effective. A clogged or worn-out sandpaper can damage the surface you're working on.

It's recommended to use a sanding block or a sanding sponge when sanding spackling. This will help you achieve a consistent and even finish. Additionally, wearing a dust mask and protective eyewear is recommended to avoid inhaling dust and debris.
