What can I use to sand and polish epoxy resin?
Use soap and warm water to clean your resin project. Wet sand the resin with 400 grit sandpaper to remove any scratches. Sand it again with 600 grit sandpaper, then with 800 grit sandpaper, 1000 grit sandpaper, and finally with 1500 grit sandpaper.
Can epoxy resin be sanded?
Cured epoxy resin is relatively difficult to sand due to its hardness. In addition, hardened epoxy resin can clog the abrasive paper relatively quickly, so that it must either be cleaned again first or replaced. With wet sanding, the clogging is significantly reduced and the abrasive paper can be used for longer.
How do you smooth out epoxy?
An uneven hardening of your epoxy resin can lead to dull, or even tacky spots. To fix an uneven epoxy finish, wait until the epoxy has dried thoroughly, and then sand it lightly with fine-grained wet sandpaper.

Can I use toothpaste to polish resin?
Using the sponge pad of your polish machine, polish the epoxy with the toothpaste. Make sure that you don’t apply too much pressure or the epoxy might burn. Let the pad gently touch the epoxy while spinning. When you run out of toothpaste, apply it again and spray it with some water!

What is resin sand?
Resin sand is a type of quartz sand that is mixed with a resin material. The chemical reaction created by the resin helps to bind and stiffen the quartz sand to make solid, hard and strong molds. A wide variety of metals can be used in resin sand cast molding due to the sand’s tolerances to high temperatures.
How do you sand epoxy?
To sand down concrete, remove any coating, seal the cracks and joints with an epoxy filler, attach metal-bonded diamond discs to a grinder, and sand the surface of the concrete. Start with a 30- or 40-grit diamond disc, and slowly increase the grit until you reach the desired finish.
