Drywall sandpaper grit refers to the size of the abrasive particles attached to the sandpaper. Grit is measured in numbers, with lower numbers indicating coarser particles and higher numbers indicating finer particles. Different grit levels are suitable for various stages of drywall finishing. Coarser grits, such as 80-120 grit, are used for initial sanding to remove imperfections. Medium grits, like 150-220 grit, smooth out surfaces and prepare them for priming. Fine grits, ranging from 240 to 320 grit, provide a smooth, polished finish to walls and ceilings.


Drywall Sandpaper: A Comprehensive Guide for Flawless Finishing

When embarking on a drywall finishing project, the choice of sandpaper plays a crucial role in achieving a smooth and professional-looking result. Drywall sandpaper comes in various types, each with its own distinct characteristics and applications. Understanding these differences is essential for selecting the right sandpaper for the different stages of finishing.

Abrasive Materials

Drywall sandpaper primarily uses two abrasive materials:

  • Aluminum oxide: A hard and durable abrasive that produces a finer finish.
  • Silicon carbide: A sharper abrasive that generates a coarser finish but is more efficient at removing material.

Grit Standards

Another important aspect of sandpaper is its grit, which refers to the size of the abrasive particles. The lower the grit number, the coarser the sandpaper, while the higher the grit number, the finer the finish. Common grit standards range from 60 to 220, with each grit finding specific use in the drywall finishing process.

Common Types of Drywall Sandpaper

Depending on the project stage and desired finish, various types of drywall sandpaper are commonly used:

  • Open-coat vs. closed-coat: Open-coat sandpaper has wider spaces between the abrasive particles, allowing dust to escape more easily. Closed-coat sandpaper has a tighter arrangement of particles, making it more durable but prone to clogging.
  • Fine-grit sandpaper (120-220 grit): Used for sanding between coats of joint compound to smooth out imperfections and create a uniform surface.
  • Medium-grit sandpaper (80-120 grit): Suitable for sanding larger areas of drywall to remove excess joint compound and prepare the surface for painting or texturing.
  • Coarse-grit sandpaper (60-80 grit): Utilized for initial sanding of raw drywall to remove imperfections and prepare it for finishing.

By carefully choosing the right type and grit of drywall sandpaper, you can ensure a seamless and professional-looking finish for your drywall project.

Grit Standards and Their Significance in Drywall Finishing

Drywall sanding is an essential step in achieving a smooth and flawless finish for walls and ceilings. The grit of the sandpaper you use has a significant impact on the quality of your finish. Understanding the different grit standards will help you choose the right sandpaper for each stage of your project.

Coarse Grit: Smooth Out Uneven Surfaces

  • Coarse-grit sandpaper (80-120 grit) is used to remove rough spots, sand down high points, and smooth out uneven surfaces.
  • It is used in the early stages of drywall finishing to prepare the surface for subsequent coats.

Medium Grit: Remove Imperfections and Level the Surface

  • Medium-grit sandpaper (150-180 grit) is used to remove surface imperfections, such as nail pops and joint compound ridges.
  • It helps level the surface and create a smooth base for the next coat of paint or primer.

Fine Grit: Achieve a Flawless Finish

  • Fine-grit sandpaper (220-320 grit) is used for the final sanding step. It removes any remaining sanding marks and creates an ultra-smooth surface.
  • It helps achieve a professional-looking finish that is ready for painting or wallpapering.

Choosing the Right Grit for the Job

Selecting the appropriate sandpaper grit depends on the stage of the finishing process and the desired result. Here’s a general guide:

  • For initial sanding: Use coarse grit (80-120) to remove imperfections and level the surface.
  • For intermediate sanding: Use medium grit (150-180) to smooth out the surface and eliminate minor ridges.
  • For final sanding: Use fine grit (220-320) to create a flawless finish that is ready for paint or other coatings.

Remember, it is always better to start with a coarser grit and progressively move to finer grits as you progress through the finishing process. This ensures a smooth and even finish without damaging the drywall surface.
