How to Smooth and Polish Scratched Corian Counter-tops before and after

Things to keep in mind

Deeper the scratch the more course the sandpaper will need to be.

Random orbital sander and variable speed buffer will yield way better results.

Using car compound may seem strange, but keep in mind it is basically an abrasive polish, and it tends to be very durable.

There is a pattern that our industry uses to polish stone which may be applied to Corian counters. Its left to right, right to left, up to down, down to up, and then left diagonal to right diagonal, lastly right diagonal to left diagonal. It takes alot of time to follow these steps but to avoid swirl marks, its worth it. Nice video.

Ok, I've been installing solid surface countertops since 1999. I'm certified for Corian, Staron, HiMac, and Formica. When the sheets arrive from the factory, they are covered by shrink wrap film, and they are a high gloss. When you begin the finishing process you actually dull it down, starting at 120 grit, removing all the defects. Then carefully working your way through increasingly finer grits until you reach the sheen you are looking for. This can go as high as 600 grit, and different 3M pads. When your solid surface top shows multiple scratches, it is due to polishing it from cleaning. You don't want a high sheen on the surface, it will show every scratch. Take it to just above a satin finish and just below a semi gloss and you will have a longer lasting finish. One more thing, don't wipe down your solid surface with papper towels, they are abrasive and will polish the surface, allowing the scratches to show more readily

I've had my Corian countertop for well over 15 yrs and it looks so dull and has scratches. I had no idea that it could be sanded or polished. Thank u so much for this video

Great job on this. I wish all how-to’s were done this well.

Nice job. Thinking about getting quartz or Corian. Was looking into care for these solid surfaces when I ran across this video. I honestly wasn’t sure if or how easy these were to sand. Thanks for the video.

I’ve enjoyed your video. I’m going to give my Corian a try. Being Corian it’s almost impossible to hurt it. Cheers!

[infomercialguy]

question....(great video by the way!!) is turtle wax rubbing compound the same as the car compound you used? i want to do it just like you. thanks. lmk. and, once again, GREAT WORK that was soooo helpful. also, do you think 400 grit and then 600 grit it "too" shiny? what is the highest grit you would go to??? thanks!!

[pj-light-glass]

That helps and confirmed what I figured I could do. I already have everything to do this. 🙂

Hey, I was excited about following these directions. For some reason, my countertops turned out really dull.

[NativeSD]

Have you done any similar videos with Black Corian. I suspect Black is the most unforgiving when it comes to finishing.

[HenschelFamily]

Hey there. Thanks for the great video. Two questions - first, can I use a drill with a pad for the polishing step of the process? Does it have a high enough rpm? Also, I’m having a hard time finding the right buffer pad. Could you recommend the best option?

[Mr.BalboaYT]

Also can you use diamond grit pads, the same as you would use on marble. And can you use a 5x export powder compound

[anitaaustin]

Good simple explanation 👏 will try. Do you recommend a sealant?

[starlingshan]

Nice video and great demonstration! We have a Corian counter top too. I wonder how often can you sand/polish it? It gets scratches fairly easily

[stephenfunk]

Can you use a rectangular vibratiion sander, the kind that takes 1/3 of a sheet?

[Logan.Ninefingers]

I'm advised to start at 240, the 400, then ultra fine grey scotchbrite

I heard Corian is more easily to clean compare Marble and Granite especially with stain. Does Corian have colors white & gray with vein like engineer marble.

[samehbasily]

How can i fix corian sheet to sheet metal 6mm in vertical position all the sheet 12mm weight 80 kg nearly

[AaronMCook]

But what clear coat sealer is used? I have dings and gouges and ither urethane goops and bumps.
I need to sand and reseal… not polish.

[benjhafner]

How long/many times do you used the boards? Would you take corian again?
