When it comes to achieving a high-quality finish, sanding is one of the most important steps in any surface preparation process. Whether you are working with wood, metal, automotive panels, or coatings, one principle stands above all others. At Derekh Abrasives, we call it the Golden Rule of Sanding:

Never skip a grit.

What Is the Golden Rule of Sanding?

The Golden Rule of Sanding is the practice of sanding in logical stages, moving gradually from a coarser grit to finer grits. Each sanding stage is designed to remove the scratches left behind by the previous grit, refining the surface step by step until the desired smoothness is achieved.

Skipping grits may seem like a time-saving shortcut, but it often leads to visible scratches, uneven finishes, and costly rework.

Why Grit Progression Is Essential

Every abrasive grit has a specific purpose. Coarse grits are used for heavy material removal, while finer grits smooth and prepare the surface for finishing. If a grit is skipped, the finer abrasive may not be able to remove the deeper scratches left behind, resulting in defects that become obvious once paint, varnish, or coatings are applied.

By following proper grit progression, you ensure:

• A smoother, more consistent surface
• Better adhesion of paints and coatings
• A professional-quality finish
• Reduced time and material waste in the long run

A Typical Sanding Sequence

While applications may vary, a general sanding progression looks like this:

• Coarse sanding (60–80 grit): Removes old finishes, rust, or surface imperfections
• Medium sanding (120–180 grit): Smooths the surface and removes coarse scratches
• Fine sanding (220–320 grit): Prepares the surface for finishing
• Ultra-fine sanding (400 grit and above): Ideal for final preparation or sanding between coats

Using the correct Derekh Abrasives product at each stage ensures optimal performance and durability.

The Abrasive Do the Work

Another key to effective sanding is applying consistent, moderate pressure. Excessive force can damage the surface, reduce abrasive life, and lead to uneven results. High-quality abrasives, such as those supplied by Derekh Abrasives, are designed to cut efficiently without the need for heavy pressure.

Quality Results Start with the Right Abrasive

Following the Golden Rule of Sanding is not just good practice—it is essential for achieving superior results. With the right grit progression and reliable abrasives, you can work more efficiently and deliver finishes that meet professional standards every time.
