As an expert in home improvement and renovation, I can provide some detailed guidance on the best practices for sanding drywall. Sanding is an essential step in preparing a wall for painting or further finishing. It helps to smooth out any imperfections and ensure a professional-looking finish. Here’s a comprehensive guide on what grit sandpaper to use and how to go about the process:
### Choosing the Right Sandpaper Grit for Drywall
Start with a Coarser Grit: When you begin sanding drywall, it's generally recommended to start with a coarser grit sandpaper. This allows you to remove larger imperfections and level the surface more quickly. A 120-grit sandpaper is a common starting point for most drywall sanding projects. It's coarse enough to make quick work of smoothing out the wall but not so rough that it will leave deep scratches.
Medium Grit for Fine Finishing: After you've used the 120-grit to level the surface, you can move on to a medium grit sandpaper, such as 150-grit. This will help to further smooth out the wall and remove any finer imperfections that the coarser grit may have left behind.
Finish with a Fine Grit: For the final sanding, you can use a fine grit sandpaper like 220-grit. This is especially important if you're planning to apply a glossy or semi-gloss finish, as it will provide a smooth surface that will reflect light evenly.
### Sanding Technique
Even Pressure: It's crucial to apply even pressure across the wall and ceiling surfaces to avoid creating uneven spots or gouges in the drywall. Uneven pressure can lead to a patchy appearance after painting.
Glide and Sand: Use a pole sander to glide smoothly across the taped seams and other areas that need sanding. This will help to blend the joints into the surface of the drywall, ensuring a seamless finish.
Work in Small Sections: Instead of trying to cover large areas at once, work in small sections. This allows you to focus on the quality of your sanding and ensures that you don’t miss any spots.
Inspect and Repeat: After sanding, inspect the wall for any missed spots or areas that need more attention. Repeat the sanding process as necessary until you achieve a smooth, even surface.
Clean Up: Once you’ve finished sanding, it’s important to clean up the dust. Use a vacuum cleaner with a HEPA filter or a damp cloth to remove all the dust particles. This will prevent the dust from adhering to the paint and causing an uneven finish.
### Additional Tips
Safety First: Always remember to wear safety glasses and a dust mask when sanding to protect your eyes and lungs from dust particles.
Lighting: Ensure the room is well-lit so you can clearly see the surface you are working on. This will help you spot any imperfections that need to be addressed.
Primer: After sanding, apply a primer to the wall. This will help to seal the surface and provide a better base for the paint.
Paint Quality: Use high-quality paint for the best results. Cheap paint may not adhere well to the surface and could lead to a less-than-perfect finish.
By following these steps and using the appropriate grit sandpaper, you can achieve a smooth, professional-looking finish on your drywall that will be ready for painting or other types of finishing.

After you have prepared the room for sanding, take a first pass at the walls with a pole sander with 120-grit sandpaper. Make sure that you use even pressure across the wall and ceiling surfaces. Glide the pole sander across all of the taped seams, blending the joints into the surface of the drywall.
