Can epoxy be sanded down?

Wet sanding with waterproof sandpaper is often the best approach to sanding cured epoxy. Cured epoxy is difficult to sand because of its hardness. In fact, cured epoxy is just softer than plastic laminate such as Formica® At 70°F, WEST SYSTEM® epoxy cures to 90% of maximum physical properties within 24 hours.

Simply so, how long do you have to wait to sand epoxy?

Sand the entire piece evenly. It will look terrible when you finish sanding it, but don't worry. After you pour the second coat of epoxy, it will look good as new! Depending on the epoxy you've chosen to work with, you'll have to wait between 4 and 24 hours before applying your second coat.

Subsequently, question is, how do you apply a second coat of epoxy? If you are looking for that layered look, there are two ways to achieve it: 1) First, you can wait 24 hrs after your first pour, sand down the whole piece with coarse sandpaper to create some tooth, and pour your second coat at that point, as originally described. Repeat until you reach the thickness you desire.

Also to know is, why is my epoxy cloudy after sanding?

Cloudy or dull epoxy is typically caused by excessive moisture. Specifically, moisture from excessive humidity in the area where the epoxy was applied or excessive moisture in/on the concrete application surface. Be sure to eliminate all water before applying epoxy.

Can epoxy be sanded and polished?

Start sanding the resin with 120 grit sandpaper. Make sure to sand all the surfaces of the resin part before going up to the next grit paper. It's much easier to notice a deep scratch once the resin is sanded smooth and begins to become polished. Until then, it's all just dry sanding.
