There is a specific sinking feeling that comes with spotting a scratch on a newly installed countertop. You might worry that the smooth, pristine finish is ruined forever. If your surface was natural stone or quartz, you might be right to worry—repairing those materials often requires expensive professional intervention.
However, if you have installed acrylic solid surface sheets, the news is good. One of the primary advantages of this material is its "renewability." Because the color and pattern run all the way through the material, scratches, scuffs, and even minor burns can be buffed out, restoring the surface to its original condition.
Whether you are a homeowner looking to spruce up your kitchen or a facility manager maintaining a commercial space, this guide answers the most common questions about restoring these durable surfaces.
To understand the repair process, it helps to understand the material. Unlike laminate, which is a thin layer glued to a wood base, or stone, which is porous and brittle, acrylic solid surface sheets are homogeneous. This means the composition is consistent from top to bottom.
Manufacturers like Kaiping Fuliya Industrial Co., Ltd (Koris®) design these sheets to be non-porous and stain-resistant. When a scratch occurs, you aren't removing a protective coating; you are simply displacing the material itself. Therefore, the repair process involves sanding down the surrounding area to match the depth of the scratch and then polishing it back to a uniform finish.
Before you begin, assess the depth of the damage. Is it a surface-level scuff from a sliding pot, or a deep gouge from a knife slip? The severity of the scratch determines the tools you will need.
For most repairs, you will need the following:
Mild abrasive liquid cleaner: For very fine scuffs.
Abrasive pads: Such as Scotch-Brite™ pads (green or white).
Sandpaper: A variety of grits ranging from 180 to 1000, depending on the finish.
Random orbital sander: Optional, but recommended for large areas to ensure an even finish.
Water: To clean the area and prevent dust buildup during sanding.
Microfiber cloths: For cleaning and polishing.

This is the most critical part of the process. Using the wrong sandpaper can leave the area looking dull or mismatched compared to the rest of the countertop. The goal is to blend the repair into the surrounding surface.
Refer to the table below to determine the correct sanding sequence based on your countertop's finish.
Desired Finish | Characteristics | Sanding Sequence (Grit) | Final Step |
|---|---|---|---|
Matte Finish | Low sheen, hides scratches well. Common in high-traffic areas. | 220 grit -> 320 grit | Buff with a green abrasive pad in a circular motion. |
Satin / Semi-Gloss | Soft sheen, reflective but not mirror-like. Most standard residential finish. | 320 grit -> 400 grit -> 600 grit | Buff with a white abrasive pad and mild abrasive cleaner. |
High Gloss | Mirror-like reflection. Used in luxury vanities and reception desks. | 400 grit -> 600 grit -> 1000 grit | Apply solid surface polishing compound with a wool buffer. |
For minor blemishes that haven't penetrated deep into the surface, you typically do not need sandpaper.
Clean the area: Wash the surface with soapy water to remove any grease or debris.
Apply abrasive cleaner: Pour a small amount of mild abrasive liquid cleaner on a damp sponge or cloth.
Rub in circles: Using small, circular motions, rub the scuffed area. Apply light pressure.
Rinse and dry: Wipe the area clean with water and dry it with a towel.
Check the blend: Look at the surface from different angles. If the scuff is gone and the sheen matches, you are done. If the scratch remains, proceed to the sanding method below.

If you can feel the scratch with your fingernail, you will need to sand the area. Do not be intimidated; acrylic solid surface sheets are forgiving.
Step 1: Clean and Prep
Thoroughly clean the surface. If you are using an electric sander, cover nearby cabinets or appliances to protect them from dust.
Step 2: Initial Sanding
Start with the coarsest grit sandpaper recommended for your finish (refer to the table above). If you have a matte finish, start with 220 grit.
Wet the sandpaper slightly to reduce dust.
Sand the scratch and the surrounding area in a circular motion.
Periodically wipe away the dust to check if the scratch has disappeared.
Crucial Tip: Do not just sand the scratch line. Feather out your sanding 3-4 inches around the damage to prevent creating a visible depression or "divot" in the countertop.
Step 3: Refining the Finish
Once the scratch is gone, switch to the next finer grit sandpaper (e.g., move from 220 to 320).
Sand a slightly wider area than you did in the previous step.
This step removes the tiny scratches left by the coarser sandpaper.
Repeat this process until you reach the final grit required for your finish.
Step 4: Buffing and Polishing
After the final sanding, clean the area thoroughly. Use an abrasive pad (green for matte, white for satin) to buff the surface. This restores the sheen and helps the repaired area blend seamlessly with the rest of the acrylic solid surface sheets.
While acrylic solid surface sheets from brands like Koris® are durable and impact-resistant, they are not scratch-proof. A few simple habits can keep your surfaces looking new for longer:
Use cutting boards: Never chop food directly on the surface. Acrylic is softer than steel knives.
Avoid sliding heavy objects: Dragging rough ceramic pots or heavy cast iron skillets can cause scuffs. Lift objects rather than sliding them.
Use trivets: While solid surface is heat resistant, extreme heat can cause damage or discoloration that is harder to fix than a simple scratch.
Regular cleaning: Dirt and dust can be abrasive. Regular wiping with a soft cloth prevents buildup that could cause micro-scratches over time.

Most cosmetic damage is repairable using the methods described above. However, if your surface has a deep crack, a fracture from impact, or heat blistering, you may need a professional repair.
In cases of severe damage, a technician can actually cut out the damaged section of the sheet and glue in a new piece of matching material. Because the adhesive creates a chemical bond and the seams are invisible, the countertop will look as good as new. This is a unique benefit of choosing high-quality materials like those offered by Koris®.
The beauty of acrylic solid surface sheets lies not just in their aesthetic appeal, but in their longevity. Unlike many other materials that must be replaced when damaged, solid surface allows you to erase mistakes and wear. By following these simple sanding and polishing steps, you can maintain the value and beauty of your counters for decades.
