How to Polish Corian Countertops : Step-by-step guide
Clean
Before starting to polish your Corian countertops, you need to clean the countertop as thoroughly as you possibly can. Just clean your countertop as you normally would with the help of water and a cloth. Make sure that you get the entire area of the countertop. Cleaning the countertop will remove any dirt and grime that may cause any damage to the countertop later on.
Sand
You can sand your countertop using an automatic sander, or a regular sanding block. The only difference is that a sanding block will give you greater control over what you will be doing. If the surface to be sanded is matte finish, then you will need to use between 180 and 220 grit sandpaper. In case you are sanding a semi-gloss surface, then you will need to use a 400 grit sandpaper. While a high-gloss surface will require you to start with a 400 grit sandpaper and finish with a 600 grit.
Gently sand the Corian countertop that needs to be polished, and make sure to remove all the cuts and scratches. If you’re working on high gloss surface, then go back over everything again with the 600 grit sandpaper so that you can restore everything to the high gloss that you need.
Clean Again
Take a little Corian cleaner on the cloth rags and clean off all the dust, dirt, and grime that was created from the sanding. Clean and wipe everything with the cleaner and rag cloth. After cleaning with the cleaner, rinse the rag and wipe down the countertops again.
Polish
Once the countertop gets dried up, apply some more of the Corian cleaner to one of the polishing pads. Then using a low-speed polisher, buff out the counter. Keep reapplying the cleaner as needed and use a gentle pressure to improve the general look of the countertop. This step will restore the original shine of your Corian countertops.
After this step, change the polishing pads, and add a little amount of polishing compound to the pad. Move in slow gentle strokes and adopt a circular motion to rub the polish into the countertop. Only use a polishing agent that is made specifically to work with Corian. After you have applied the polish, wipe off any remaining excess polish, and allow the surface to countertops to dry completely.

Frequently Asked Questions for How to Polish Corian Countertops
How do you restore the shine to Corian countertops?
Restoring the shine to Corian countertops involves a few straightforward steps. First, clean the surface with an ammonia-based cleaner to remove debris or grease. Then, apply a commercial countertop polish specifically designed for solid surfaces. Use a microfiber cloth to spread the polish in circular motions, then buff it off with a clean cloth. This process can significantly enhance your countertops’ shine and overall appearance, making them look new again.
How do you make Corian countertops glossy?
You can use a specialized countertop polish to achieve a glossy finish on Corian countertops. Start by ensuring the surface is clean and dry. Apply the polish generously using a microfiber cloth, working it into the surface in circular motions. Buff the area with another clean cloth to bring out the shine. If your countertops have deep scratches or dull spots, you may need to sand them lightly with fine-grit sandpaper before polishing.
What do you polish Corian with?
Corian can be polished using commercial countertop polishes that are safe for solid surfaces. Products like Granite Gold or other mild abrasive polishes work well. For a DIY approach, a mixture of baking soda and water can also serve as a gentle polishing agent. Always use a soft cloth or microfiber towel to avoid scratching the surface while applying the polish.
Can you buff out scratches on Corian countertops?
Yes, scratches on Corian countertops can often be buffed out. Use a mild abrasive cleaner or polish for light scratches and gently rub it into the scratch with a soft cloth. For deeper scratches, you may need to sand the area using fine-grit sandpaper (around 400-600 grit) before polishing it back to its original finish. This method effectively minimizes or eliminates visible scratches.
How do I make old Corian look new?
To rejuvenate old Corian countertops, clean them thoroughly with an appropriate cleaner. Next, assess the surface condition—if there are scratches or dull areas, consider sanding them lightly and then polishing them with a commercial product designed for solid surfaces. If your countertops are extensively worn or damaged, K&B Cabinets offers professional refinishing services that restore them to like-new condition.
How do you bring Corian back to life?
Bringing Corian back to life involves deep cleaning, polishing, and possibly sanding if significant imperfections exist. Start by using an ammonia-based cleaner to remove stains and dirt. Afterward, apply a suitable countertop polish in circular motions and buff it off for an enhanced shine. If necessary, K&B Cabinets provides expert services that can revitalize your countertops by sanding and refinishing, ensuring they look their best.

K&B Cabinets provides expert guidance on choosing the right countertop materials to balance style, durability, and budget for your kitchen or bathroom.
Are quartz countertops better than Corian?
Quartz countertops are often considered better than Corian for certain applications due to their superior durability, heat resistance, and natural stone-like appearance. Quartz is harder and less prone to scratches or dents. It also offers better heat resistance, making it more suitable for high-heat areas like kitchens. However, Corian holds its own in affordability, seamless design, and ease of repair.
Suppose you’re unsure which material suits your needs. In that case, the team at K&B Cabinets can help you explore quartz and Corian options, along with other premium materials, to find the perfect match for your kitchen or bathroom.
What are Corian design countertops?
Corian design countertops are tailored solid-surface solutions created to fit your unique kitchen or bathroom aesthetic. These countertops are available in a wide range of colors, patterns, and textures, mimicking the look of marble, concrete, or natural stone while providing the benefits of Corian’s non-porous and easy-to-maintain surface.
K&B Cabinets offers a wide selection of Corian design countertops and professional installation services to help homeowners achieve the perfect balance of style and functionality.
Is Corian a good surface for a kitchen?
Corian is an excellent kitchen surface because it is easy to clean, hygienic, and highly customizable. Its non-porous nature ensures that spills won’t seep into the surface, preventing stains and bacteria growth. Additionally, its seamless appearance makes cleaning and maintenance hassle-free. While it is not as heat-resistant as quartz or granite, trivets and cutting boards can help preserve its appearance.
Is Corian better than Quartz?
Both Corian and quartz offer unique advantages. Corian is known for its seamless, thermoformable nature, allowing it to be shaped into custom designs and integrated with sinks and backsplashes. It’s also more easily repairable, making minor scratches and chips a breeze. Quartz, on the other hand, is exceptionally durable and resistant to scratches, heat, and stains. It’s also available in various colors and patterns, mimicking the look of natural stone. The best choice depends on your priorities. Corian might be ideal if you value seamless design and ease of repair. If durability and low maintenance are your top concerns, quartz could be the better option.
Does Corian crack easily?
While Corian is generally durable, it’s more prone to cracking than quartz, especially with sudden temperature changes or heavy impacts. However, minor cracks can often be repaired by a professional. To minimize the risk of cracking, avoid placing extremely hot or cold items directly on your Corian countertop and use cutting boards to protect the surface.
Is Corian high-end?
Corian is considered a mid-range countertop material. While it’s not as high-end as some natural stone options like granite or marble, it offers a luxurious look and feel at a more affordable price point.
What is a cheaper alternative to Corian?
Laminate countertops are a more affordable alternative to Corian. They come in various colors and patterns and are easy to clean and maintain. However, laminate is less durable than Corian and more prone to scratches and damage.
Is Corian outdated?
Corian has been around for decades and remains a popular choice for countertops today. While newer materials like quartz have gained popularity, Corian continues to be a good option for those who value its seamless design, ease of repair, and affordability.
Is Corian cheaper than granite?
Corian typically costs less than granite, with prices ranging from $45 to $65 per square foot installed, compared to granite’s $60 to $100+ per square foot. At K&B Cabinets, we understand budget considerations are important for kitchen remodeling projects, so we offer a wide range of countertop options to complement our premium cabinet selections. The cost-effectiveness of Corian makes it an excellent choice for homeowners looking to achieve a high-end look while maintaining budget flexibility for other elements like our custom kitchen cabinets or bathroom vanities.
What is Corian made of?
Corian is a solid surface material comprising approximately 33% acrylic resin (polymethyl methacrylate or PMMA) and 66% natural minerals (primarily aluminum trihydrate derived from bauxite ore). This unique composition, developed by DuPont, creates a non-porous, durable, and aesthetically pleasing surface. When paired with K&B Cabinets’ premium cabinetry, Corian countertops create a cohesive, modern look that enhances any kitchen or bathroom design.
Is Corian a plastic or stone?
Corian is neither purely plastic nor stone— a composite material that combines the best properties of both. While it contains natural minerals, it’s engineered with acrylic polymer to create a solid surface material that offers unique benefits over traditional plastic and stone surfaces. This hybrid nature allows for seamless installations and repairs, making it an ideal choice for homeowners seeking a durable yet customizable countertop solution for their kitchen or bathroom renovation projects.
Is Corian expensive?
While Corian represents a mid-range investment in countertop materials, its value proposition is excellent when considering its durability, maintainability, and versatility. The initial cost of Corian typically ranges from $45 to $65 per square foot installed, positioning it as a more affordable alternative to high-end natural stone options. At K&B Cabinets, we can help you balance your budget across various kitchen or bathroom remodel elements, ensuring you get the most value from your investment in countertops and our premium cabinet collections.
How long will Corian last?
Corian countertops can last 20-30 years or more with proper care and maintenance. Their durability is one of the main reasons they remain a popular choice for kitchen and bathroom applications. Unlike some natural stone surfaces, Corian can be professionally refinished to remove scratches and wear patterns, restoring it to its original condition. When you choose K&B Cabinets for your remodeling project, our experts can guide you through the best practices for maintaining both your Corian countertops and our high-quality cabinets to ensure maximum longevity for your entire kitchen or bathroom installation.
