Factors to Consider when Buying Sandpaper for Wood

When it comes to woodworking, sanding is an essential step in achieving a smooth and polished finish. Whether you are working on a small DIY project or a large-scale woodworking task, choosing the right sandpaper is crucial for achieving the desired results. With a wide variety of sandpaper options available in the market, it can be overwhelming to make the right choice. In this article, we will explore the factors to consider when buying sandpaper for wood, ensuring that you make an informed decision for your woodworking needs.

1. Grit Size

The grit size of sandpaper refers to the coarseness or fineness of the abrasive particles on the paper. It is denoted by a number, with lower numbers indicating coarser grits and higher numbers indicating finer grits. The choice of grit size depends on the type of wood and the level of sanding required.

For initial sanding or removing rough surfaces, a coarse grit sandpaper such as 40 or 60 grit is suitable. These grits are effective in removing paint, varnish, or heavy imperfections from the wood surface. However, they may leave visible scratches, which will require further sanding with finer grits.

Medium grit sandpapers, ranging from 80 to 120 grit, are commonly used for general sanding purposes. They are ideal for smoothing out rough surfaces and preparing the wood for finishing. These grits are versatile and can be used for both initial sanding and final smoothing.

For achieving a smooth and polished finish, fine grit sandpapers such as 150 to 180 grit are recommended. They are effective in removing small imperfections, scratches, and preparing the wood for staining or painting. Additionally, extra fine grits like 220 to 400 grit can be used for final sanding and achieving a mirror-like finish.

Aluminum oxide sandpaper is one of the most commonly used types of sandpaper for woodworking. It is durable, long-lasting, and suitable for both hand sanding and power sanding. Aluminum oxide sandpaper is available in various grit sizes and is effective in sanding wood, metal, and painted surfaces.

2.2. Garnet Sandpaper

Garnet sandpaper is another popular choice for woodworking. It is made from natural garnet minerals and is known for its excellent cutting ability. Garnet sandpaper is ideal for sanding bare wood and is less likely to clog compared to other types of sandpaper.

2.3. Silicon Carbide Sandpaper

Silicon carbide sandpaper is commonly used for sanding non-ferrous metals, glass, and plastic. It is also suitable for sanding wood, especially when a finer finish is desired. Silicon carbide sandpaper is available in both wet and dry forms, making it versatile for various applications.

2.4. Wet Dry Sandpaper

Wet dry sandpaper is designed to be used with water or oil, allowing for wet sanding. It is commonly used for automotive refinishing, as well as for sanding wood and metal surfaces. Wet dry sandpaper is available in various grit sizes and is known for its durability.

3. Backing Material

The backing material of sandpaper plays a crucial role in its performance and durability. There are three main types of backing materials used in sandpaper:

3.1. Paper Backing

Paper backing is the most common type of backing material for sandpaper. It is flexible, lightweight, and suitable for hand sanding. Paper-backed sandpaper is available in various grades of thickness, with heavier grades offering more durability for power sanding.

3.2. Cloth Backing

Cloth backing is more durable and tear-resistant compared to paper backing. It is commonly used for heavy-duty sanding and is suitable for power sanding. Cloth-backed sandpaper is ideal for sanding metal surfaces and is less likely to tear or wear out quickly.

3.3. Film Backing

Film backing is the most durable type of backing material for sandpaper. It is tear-resistant, waterproof, and suitable for wet sanding. Film-backed sandpaper is commonly used for automotive refinishing and is less likely to clog compared to other backing materials.

4. Durability

The durability of sandpaper is an important factor to consider, especially for large-scale woodworking projects. Low-quality sandpaper may wear out quickly, resulting in frequent replacements and additional costs. It is advisable to choose sandpaper from reputable brands known for their durability and longevity.

Additionally, the durability of sandpaper can be enhanced by using sanding blocks or sanding sponges. These tools provide a firm and even surface for sanding, reducing the wear and tear on the sandpaper.

5. Cost

The cost of sandpaper can vary depending on the brand, quality, and quantity. It is important to consider your budget and the scale of your woodworking project when choosing sandpaper. While it may be tempting to opt for cheaper options, it is essential to prioritize quality and durability to achieve the best results.

Buying sandpaper in bulk or multipacks can often be more cost-effective compared to purchasing individual sheets or rolls. However, it is important to consider the shelf life of sandpaper, as it can deteriorate over time and lose its effectiveness.


Choosing the right sandpaper for wood is crucial for achieving a smooth and polished finish in woodworking projects. Factors such as grit size, type of sandpaper, backing material, durability, and cost should be carefully considered before making a purchase. By understanding these factors and selecting the most suitable sandpaper, you can ensure that your woodworking projects are completed to the highest standards.
