Acrylic solid surface countertops (like Corian, Hi-Macs, or Koris) are durable, but over time, they can develop scratches, stains, and dullness. Fortunately, with the right techniques, you can restore them to a like-new finish. Below is a step-by-step process for sanding, polishing, and sealing your countertop, complete with amazing before & after results.
Tools & Materials Needed
Orbital sander or hand sanding block
Wet/dry sandpaper (180, 320, 600, 800, 1000 grit)
Polishing compound(for acrylic surfaces)
Non-abrasive cleaner
Microfiber cloths & buffing pads
Step 1: Deep Cleaning
Before sanding, remove grease, grime, and stains:
1. Use a non-abrasive cleaner and a soft sponge.
2. For stubborn stains, apply a baking soda paste and gently scrub.
3. Rinse thoroughly and dry.
Step 2: Sanding Out Scratches & Imperfections*
Start with **coarse grit** and progress to **fine grit** for a smooth finish:
1. 180-320 grit – Removes deep scratches (use lightly).
2. 400-600 grit – Smoothens the surface.
3. 800-1000 grit – Preps for polishing.
4. 1500+ grit – Creates a satin-smooth finish(if needed).
Pro Tip: Always sand wet (with water) to avoid overheating and clogging the sandpaper.

Step 3: Polishing to a High Gloss
After sanding, polish to restore shine:

2. Use a buffing pad(or drill attachment) in circular motions.
3. Wipe off residue with a microfiber cloth.
