Sandpaper grain

Sandpaper has a grit that can be coarse or fine. The grit on sandpaper provides the grinding action while sanding. If the sandpaper has a grain that is coarse, then paint or varnish will be easy to sand away. If you use sandpaper with a fine grit, it will only slightly roughen or mattify the surface. Besides the size or coarseness of the sandpaper grain, there are also different types!

Different types of grit sandpaper

Sandpaper can be sprinkled with different types of grit. Each type of sandpaper grain has its specific characteristic. For example, there is sandpaper with a universal grit for sanding any material, substrate or surface. But there is also sandpaper with a grit specifically for sanding wood, metal, stainless steel, aluminum, steel or other material. The types of grit on sandpaper are:

  • Aluminum oxide
  • Ceramic
  • Silicon carbide

What grit sandpaper do I need?

What grit sandpaper you need depends on the paint, varnish or surface you want to sand. Do you want to sand away paint or varnish completely? Then you need sandpaper with a coarse grit. If you only want to lightly sand the surface, sandpaper with a finer grit will suffice. Are you going to sand the car? Then we recommend sanding in steps from coarse to fine for a sleek and smooth body.

Sanding undercoat grain

Grit to sand primer is different. Sanding primer is done with several grit sizes. Start sanding primer with P240 grit. Then sand the primer in steps from P320, to P400 to P500 or P600. The primer is now tight and smooth to be overpainted with paint or lacquer.

Frequently Asked Questions

Which grit to use for sanding?

When sanding surfaces, it's important to choose the right grit. For removing old paint or lacquer, you typically use a coarser grit, such as 80 or 120. For smoothing the surface and preparing it for painting, a grit of 220 to 400 is suitable. For finishing and polishing, you can use a very fine grit of 600 or higher. Always choose the grit that fits your specific project and the material you're working on.

What is the finest grit sandpaper?

The finest grit sandpaper is grit 400 and higher. These grits are perfect for sanding delicate surfaces and achieving a smooth finish.

How to choose the right grit size for sandpaper?

When choosing the right grit size for sandpaper, it's important to consider the material you're sanding and the desired finish. Coarse sandpaper (grit 40-80) is ideal for removing large imperfections or old paint. For a smoother finish, use medium grit (grit 120-220), which is perfect for between layers or smoothing surfaces. For a super-smooth finish, such as when working with paint, choose fine sandpaper (grit 400-600). Remember, it's always good to start with a coarser grit and gradually move to finer grits for the best results.

Which grit sandpaper for car paint?

For car paint, it is recommended to use sandpaper with a grit of 400 to 600 for surface preparation. For finishing, grits of 1000 to 2000 can be used to achieve a smooth and glossy finish. Choose the grit based on the condition of the paint and the desired result.

What grit for sanding primer on a car?

When sanding primer on cars, it's best to start with a grit between 180 and 240. This provides good adhesion without damaging the underlying paint. After sanding, you can move to a finer grit, such as 320 to 400, for a smoother result before applying the top coat.

What is sandpaper with grit 20?

Sandpaper with grit 20 is very coarse sandpaper, ideal for quickly removing material such as paint, varnish, or rust. It is typically used in the initial stages of sanding to create a smooth base before moving on to finer grits. Perfect for heavy sanding tasks!

Which grit sandpaper should I use?

The choice of sandpaper grit depends on the task at hand. For sanding rough surfaces, use coarse sandpaper (grit 40-60), while for smooth finishes, finer sandpaper (grit 220-400) is needed. If you're aiming for a middle step, you can use medium grit sandpaper (grit 80-120). Make sure to choose the right grit for the best result!

What grit should I use between layers?

For sanding between layers, typically use a grit of 400 to 800. This ensures good adhesion without removing too much material. Choose a finer grit for the final layer to achieve a smoother result.

Which grit for removing old paint?

For removing old paint, it's best to start with sandpaper in the range of grit 80 to 120. This helps to effectively remove the old paint without damaging the underlying layer. If you're aiming for a smoother finish, you can switch to a finer grit, such as 240 or higher, afterwards.
