Woodworking Tips: Using Sand Paper for Best Results


Updated on:

Woodworking is a craft that requires precision and attention to detail. Whether you are a professional woodworker or a DIY enthusiast, achieving a smooth and polished finish on your projects is essential. One of the most important tools in your arsenal for achieving this is sandpaper. In this article, we will explore the different types of sandpaper available, their uses, and provide you with some valuable tips on how to use sandpaper for the best results.

The Basics of Sandpaper

Sandpaper, also known as abrasive paper, is a versatile tool used for smoothing surfaces and removing material. It consists of a sheet of paper or cloth with an abrasive material attached to it. The abrasive material can be made from various substances such as aluminum oxide, silicon carbide, or garnet. The grit size of the abrasive material determines the coarseness or fineness of the sandpaper.

Types of Sandpaper

There are several types of sandpaper available, each with its own specific uses:

  • Aluminum Oxide Sandpaper: This is the most commonly used type of sandpaper. It is durable and suitable for a wide range of applications, including wood and metal sanding.
  • Silicon Carbide Sandpaper: This type of sandpaper is ideal for sanding hard materials such as glass, ceramics, and stone. It is also commonly used for automotive sanding.
  • Garnet Sandpaper: Garnet sandpaper is a natural abrasive that is gentle on surfaces. It is often used for fine sanding and finishing.
  • Wet Dry Sandpaper: As the name suggests, this type of sandpaper can be used both wet and dry. It is commonly used for automotive sanding and painting prep.
  • Drywall Sandpaper: Drywall sandpaper is specifically designed for sanding drywall joints and patches. It has a special coating that prevents clogging.
  • Glass Sanding Paper: Glass sanding paper is used for sanding and polishing glass surfaces. It is available in various grit sizes to achieve different levels of smoothness.

Choosing the Right Grit

The grit size of sandpaper determines how coarse or fine the abrasive material is. The higher the grit number, the finer the sandpaper. Here are some general guidelines for choosing the right grit:

  • Coarse Grit Sandpaper (40-60 grit): Use coarse grit sandpaper for heavy material removal, such as shaping and leveling rough surfaces.
  • Medium Grit Sandpaper (80-120 grit): Medium grit sandpaper is suitable for general sanding and smoothing surfaces.
  • Fine Grit Sandpaper (150-180 grit): Use fine grit sandpaper for final sanding and preparing surfaces for finishing.
  • Extra Fine Grit Sandpaper (220-400 grit): Extra fine grit sandpaper is used for achieving a smooth and polished finish.

Using Sandpaper for Woodworking

Wood sanding paper is one of the most commonly used types of sandpaper in woodworking. Here are some tips for using sandpaper effectively:

1. Prepare the Surface

Before you start sanding, make sure the surface is clean and free from any debris. Use a brush or vacuum to remove dust and particles. This will prevent the sandpaper from getting clogged and ensure a smooth sanding process.

2. Choose the Right Sandpaper

Depending on the task at hand, choose the appropriate type and grit of sandpaper. For rough surfaces, start with a coarse grit sandpaper and gradually work your way up to finer grits for a smooth finish.

3. Use Sanding Blocks

Using sanding blocks can help distribute pressure evenly and prevent uneven sanding. Wrap the sandpaper around a sanding block or use a sanding sponge for better control and consistent results.

4. Sand with the Grain

When sanding wood, always sand with the grain to avoid scratches and achieve a smoother finish. Sanding against the grain can cause tear-out and leave unsightly marks on the surface.

5. Apply Even Pressure

Apply even pressure while sanding to avoid creating low spots or uneven surfaces. Keep the sandpaper flat against the surface and use long, smooth strokes for best results.

6. Check Your Progress

Periodically check your progress by wiping away dust and inspecting the surface. This will help you identify any areas that need further sanding or attention.

7. Use Different Grits for Finishing

For a smooth and polished finish, use progressively finer grits of sandpaper. Start with a medium grit sandpaper and gradually work your way up to extra fine grits. This will help remove any remaining imperfections and leave the surface ready for finishing.


Sandpaper is an essential tool for achieving a smooth and polished finish in woodworking. By choosing the right type and grit of sandpaper and following the tips mentioned in this article, you can achieve professional-looking results. Remember to always prepare the surface, use sanding blocks, sand with the grain, apply even pressure, and check your progress regularly. With the right techniques and tools, sanding can become a satisfying and rewarding part of your woodworking process.
