The Best Abrasives for Refinishing Cabinets, Furniture, and Interior Trim

When refinishing cabinets, furniture, interior trim, or doors, the quality of your abrasives matters just as much as the quality of your finish. Using the right sanding materials ensures smooth surfaces, proper adhesion, and a professional result that lasts.

 

That’s why many professionals trust Uneeda abrasives. As a family-owned and operated company for over 60 years, Uneeda has built a reputation for producing some of the best abrasives in the world. Their abrasives are engineered to last up to 20 times longer than many competitors, making them a smart investment for professionals and DIYers alike.

 

If you're using an Ekasand 3×4 sander, Uneeda offers every abrasive you need to complete your sanding process from start to finish.

 

But before choosing abrasives, it's important to understand how sanding works and why grit progression matters.

Understanding Sandpaper Grit and the Sanding Schedule

If you're new to finishing, the most important concept to understand is the sanding schedule.

 

A sanding schedule refers to the order of abrasive grits used during the sanding process. Following the correct progression helps you achieve a smooth surface without deep scratches or imperfections.

 

Sandpaper is numbered according to its abrasive size:

• 80 grit – very coarse

• 100 grit – coarse

• 120 grit – medium coarse

• 150 grit – medium

• 180 grit – medium fine

• 220 grit – fine

• 320 grit and above – very fine finishing

 

The rule is simple:

Lower numbers cut faster. Higher numbers refine the surface.

 

When sanding any surface—whether you are using sandpaper, sanding film, or sanding screens—you should begin with a lower grit and gradually move to higher grits.

 

Ideally, you should move one grit step at a time rather than skipping several grits. This ensures each scratch pattern is removed by the next grit.

 

While it is sometimes possible to skip one grit and still achieve good results, professionals generally recommend progressing sequentially through the grits for the best finish.

Typical Sanding Schedule for Cabinets and Furniture

Although there is not always a single “correct” sanding schedule, the following progression works well for many cabinet refinishing and furniture finishing projects.

 

Finish Removal or Surface Preparation

Start with:

• 80 grit – heavy finish removal or leveling rough surfaces

• 100 grit – refining the initial cut

• 120 grit – preparing the surface for smoothing

Surface Smoothing

• 150 grit – smoothing the substrate

• 180 grit – refining the scratch pattern

Final Prep Before Finishing

• 220 grit – final surface preparation before primer or sealer

Between Coats

• 320 grit or finer – sanding between coats of primer, sealer, or finish

 

This sanding progression helps ensure your substrate is smooth and properly prepared for coatings.

Foam Abrasives: Where They Shine

Uneeda also produces high-quality foam abrasives designed for sanding areas that traditional paper can’t reach easily.

 

Unlike standard sandpaper, foam abrasives are labeled:

• Coarse

• Coarse+

• Medium

• Medium+

• Fine

• Very Fine

• Super Fine

• Super Fine+

 

Even though they are labeled differently, they still follow the same sanding progression principles.

Best Uses for Foam Abrasives

The coarser and medium foam abrasives are ideal for:

• Finish removal

• Scuff sanding

• Detailed profiles

• Chair spindles

• Rungs

• Moldings and trim

• Carved or intricate furniture

 

Because foam pads conform to surfaces, they are especially helpful for rounded edges and detailed trim work.

Fine Foam Abrasives

The finer foam abrasives are best used for:

• Sanding between sealer coats

• Sanding between primer coats

• Smoothing finish coats

• Removing dust nibs and imperfections

• Creating a mechanical bond for the next coat

 

They help ensure each layer of finish adheres properly while keeping the surface smooth.

What Foam Abrasives Are Not Designed For

While foam abrasives are incredibly useful, they are not designed for aggressive sanding or leveling large surfaces.

 

Foam abrasives should not be used for:

• Heavy finish removal

• Aggressive stripping

• Level sanding large flat panels

 

For those tasks, traditional abrasives like sandpaper, sanding film, or sanding discs are the better choice.
