    Hello,

    I’m new to resin and have an issue with sanding.

    Once my piece is cured, I pull it out and sand the sides and sometimes the odd edges that might be a little wonky, when I do this I end up sanding off the nice shiny outer layer. If I sand enough I can sand it all off and make the piece matte but I’m wanting it to be shiny.

    How do I sand off my rough edges without removing the top layer of shine, I’ve watched a million vides but don’t understand how to fix this aside from doing another thin layer of resin overtop. I’ve tried various metal cleaning agents as suggested in various videos but this doesn’t bring the sanded areas back to their previous shine.

    Any tips or tricks would be greatly appreciated! Thank you!

    Best, Tobie

    I am using Amazing Resin.

    Hi Tobie,

    You will want to sand and finish with a 1000 grit or higher sandpaper. I like to end with these finishing papers (https://www.riogrande.com/Product/3M-Tri-M-Ite-Imperial-Polishing-Paper-Assortment/337308). They get my pieces as close to shiny as possible. After using the papers, I like to use the Novus polishing kit which gets them a little more shine as well. https://shop.resinobsession.com/collections/tools-and-supplies/products/novus-resin-polishing-kit

    What about spraying it with clear acrylic spray after sanding with a fine grit? Would that bring back a high shine?

    Yes, but you will want to be sure you end with a 1000 grit or higher sandpaper. Otherwise, you will still see ‘frostiness’ underneath the spray.
