A Professional Guide to Proper Acrylic and Plastic Surface Polishing with KANABAR White Polishing Compound by King Brite

Acrylic and plastic materials—whether used in CNC machining, casting, molding, or industrial manufacturing—often share the same challenge:
surface imperfections caused by sandpaper marks, machine traces, or uneven textures.

That is why polishing is a critical process for these materials.
Skipping steps or choosing the wrong polishing compound can lead to dull finishes, wasted time, and repeated rework.

One of the most important factors in achieving a high-quality finish is selecting the right polishing compound for the job.
For acrylic and plastic surface polishing, a key product used by professionals is KANABAR White Polishing Compound (Model A-PA001), specifically designed for non-metal materials.

This article explains the role of white polishing compound, how to use it correctly, and the professional polishing workflow commonly applied in industrial environments.

What Is KANABAR White Polishing Compound and What Is It Used For?

KANABAR White Polishing Compound is a high-cut polishing compound developed specifically for plastic and acrylic applications.

It is designed to:

• Restore surface gloss
• Remove sanding marks
• Create a smooth and uniform finish
• Polish non-metal materials such as acrylic, plastic, resin, and similar substrates
  

Applications Suitable for KANABAR White Polishing Compound

This compound is ideal for surfaces that have already been shaped and pre-sanded, including:

• Cast acrylic that has been sanded
• Rigid plastic after surface preparation
• Translucent or transparent materials requiring a final gloss finish

Step-by-Step: How to Use KANABAR White Polishing Compound Correctly

1. Surface Preparation (A Mandatory Step)

Before polishing, proper sanding is essential.
Recommended sandpaper sequence:

• Deep scratches → Start with 400–600 grit
• General surface marks → 800 → 1000 → 1500 → 2000 grit

• Ensure previous sanding marks are fully removed before moving to the next grit
• Clean the surface between each step
• Wet sanding is recommended to reduce heat and minimize scratches

After sanding, the surface should appear uniformly matte, not transparent, with no deep scratches remaining.

2. Applying KANABAR White Polishing Compound

• Start the polishing machine and allow the buffing wheel to rotate
• Lightly touch the compound to the wheel for 1–2 seconds
• Begin polishing the workpiece
• Apply moderate pressure
• Move the tool evenly across the surface
• Avoid staying on one spot for too long

Continue polishing until:

• Sanding marks disappear
• The surface becomes smoother
• Light reflection and gloss begin to appear
