Solid Surface Countertops: Refinishing VS Replacing

Though solid surface also refers to granite countertops, but here I am talking about the Corian counter. When your Corian counter looks dull, you have two options: refinish or replace them. Refinishing will cost you half the replacement price if you choose to refinish. And the best part is that refinishing doesn’t take much time; you can do it in a day or two.

On the other hand, replacing your countertops can be costly and time-consuming. You will have to remove the old countertop, which can damage your cabinets. Plus, you will need to take extra care of the new countertop, so it doesn’t get damaged easily.

So, if you’re on a budget and don’t have much time, refinishing your Corian countertop is the way to go. And, if you’re wondering how to refinish Corian countertops, this article is for you.

Refinishing the Corian countertop is less expensive than replacing the whole countertop. The process of refinishing is not that difficult, but it takes a little time to do it right.

Ways to Refinish Corian Countertop (Step-by-Step)

Refinish Corian Countertop

Refinishing your solid surface countertop is relatively easy, and I’m here to walk you through the process step-by-step. Whether your countertops are looking a little dull or you just want to change up the color, refinishing is a great option.

To start, you’ll need to gather a few supplies. You’ll need –
Sandpaper in various grits (I recommend starting with 100 grit and working your way up to 400 grit)

  • A drill
  • Some painter’s tape
  • Several rags
  • Gloves
  • Safety goggles
  • A respirator mask

You can use any solid surface refinishing kit for the actual refinishing material.

Step-1: Sanding the Counters

Once you have all of your supplies, the first step is to sand your countertops. Sanding your counters will help to make the surface rough so that the new refinishing material can adhere better.

Using sandpaper in progressively higher grits, start sanding your countertops in a circular motion. Start with the 100 grit sandpaper and work up to the 400 grit. Be sure to sand evenly, in the same direction, to avoid creating scratches. When you’re finished sanding, wipe down the counters with a damp rag to remove dust.

Step-2: Applying Painter’s Tape

After you’ve finished sanding, it’s time to tape off any areas that you don’t want refinishing material on. It includes things like backsplashes, appliances, and sinks.

Once everything is taped off, use a rag to remove any dust or debris from the countertops. You can also apply painter’s tape around the edges of your countertops. It will help to create a clean line and prevent any accidental over-spray.

Step-3: Applying the Refinishing Material

Now it’s time for the fun part – applying the refinishing material! You will find a variety of refinishing kits available in the market. But make sure to select the one specifically made for Corian countertops. You can also use commercial countertop polish. Don’t dare to try an abrasive household cleaner.

To apply the refinishing material, you will use a process called “spraying and back-rolling.” It simply means spraying the refinishing material onto the countertop and then using a roller to spread it evenly.
Start by pouring some of the refinishing material into a paint tray.

Next, mix the refinishing material thoroughly using your drill and a paint mixer attachment. Once it’s mixed, pour it into your paint sprayer.

Now, start spraying the refinishing material onto your countertops in even strokes. Be sure to hold the sprayer about 12 inches away from the surface as you spray. After you’ve sprayed an area, use a roller to spread the material evenly.

Continue this process until all your countertops are covered with a thin layer of refinishing material.

However, you can also follow the instructions on your chosen kit and apply an even layer of refinishing material over the entire countertop. Be sure to work in a well-ventilated area and wear your respirator mask!

Step-4: Let It Dry and Cure

Once you’ve applied the refinishing material, it’s time to let it dry and cure. This process usually takes about 24 hours. During this time, be sure not to use your countertops or expose them to water or moisture. After 24 hours, your countertops should be completely dry and cured.

For some refinishing materials, you may need to sand them again when it dries properly. So, for those refinishers, use the 400 grit sandpaper and lightly sand the entire surface until it’s smooth. This may take some time, so be patient!

Step-5: Seal the Solid Surface Countertop

Once the final sanding has been done, you can apply a sealer on top of it though it’s optional. But sealing will help keep the refinishing look for a long time, keeping the scratches away. You will find a variety of sealers available in the market, but make sure to select the one specifically made for Corian countertops.
To apply the sealer, simply follow the instructions on the chosen kit.

In most cases, you will need to apply two coats of sealer. Be sure to let each coat dry completely before applying the next one. It will give your counter a glossy finish and protect it from fine scratches and other damage.

And that’s it – you’re done! Your Corian countertop surfaces should now be refinished and look as good as new!
Finally, remove the tape and enjoy your newly refinished countertops! Make sure to clean them regularly with non-abrasive cleaning products to keep them looking their best.

Congratulations! You’ve just learned to revitalize Corian countertops. Now go out and enjoy your beautiful new kitchen counter!

Resurfacing is a good option if you want to change the color of your countertop or want to add a new design.
