Sanding Corian Countertop. Sand Your Countertop for Painting. We recommend using sanding paper with a fine grit such as 400.
Inspect your edges for any pieces you may have missed. Use the sandpaper to lightly rub in circular motion over the scratched surface. No need to worry about damage to a Corian countertop.
Clean entire countertop and inspect for defects and scratches.
If you dont have a spray cleaner you can as well use warm soapy water to wipe your Corian worktop. Make the mixture using warm water in a bowl and 2-3 drops of liquid dish soap. Buff out the counter reapplying the cleaner as needed and using a gentle pressure to improve the general look of the countertop. Inspect your edges for any pieces you may have missed.
