How do I use dust saved from sanding Corian to fix scratches?
Similar to using wood dust mixed with wood glue to fill in some imperfection on a wood project. You will always see it, but most other folks won't. Kind of depends on the scratch.

If you have a scrap of your corian, put a scratch in it, take the dust, mix with some epoxy fill the scratch and sand flush. See if it works to your satisfaction. Then put away that experience to the day if and when you actually scratch your bar top. And don't forget where you put those corian sandings.


My assumption is that epoxy will stick to the corian and not pop off.
