Finishing corian
« on: June 24, 2019, 07:38 PM »
I had a deep scratch in a  corian countertop that sanded out pretty easily: ets150/3 with 150, 220 and a brown scotchbrite type pad. It is not quite back to match the original color. What is the right abrasive to get me there? I am thinking maybe a platin?

What is the current finish? Slight haze might be 500. Polished is polished.

I found that 150/220/300/400/600/800 was a good schedule to get a Corian finish that was clear and reflective but not with high gloss.  The downside is that each step higher in grit level leaves a surface that is more revealing of scratches from everyday wear and tear.

It depends on the colour and finish. I have the below in my notes.

Matt; 120, 180, 240, 320 Granat
Semi-gloss; as Matt then 500 Platin2 wet or dry
Gloss; as Semi-gloss then 1000 Platin2 wet or dry, MPA 6000 polish

You'll find a wealth of information in these threads...

I've attached a document on finishing solid surface materials.  The original came from Steve Bace in the solid surface class.  I just added to his document to create this one.   [smile]

Lots of good info here. Thanks guys. The observation about scratches becoming more evident is on the mark. It actually goes pretty fast so sanding the whole surface is easier than trying match new to old.
