Can I polish the sand coat?

General Discussion

Hello,

I don’t want to do gloss.  There’s enough resin on this board.  Can I apply polishing compound to the sand coat and buff it out?  Do I need to scuff it with 600 grit first?  Can I leave it as-is??? The finished sand coat is as glossy as I would want it.

if yes, what kind of compound should I use?

 

thanks.

Epoxy or PE resin?  Regardless, sure, you can polish the hot/sanding coat as long as you have no glass weave showing.  Use the same polishing techniques you use on a normal gloss coat; just go lighter in more more corse grits of sandpaper.  You don’t want to go too deep.  PE resin will polish out better than Epoxy.  And I would absolutely seal an Epoxy hot coat with acrylic sealer (e.g. acrylic concrete sealer) and perhaps even a PE hot coat.
