how to sand resin smooth

Resins are typically viscous substances that convert into rigid polymers through a curing process.Resin material can include both solid and highly viscous materials, but commonly refers to liquids that harden based on heat, setting agents, or light. Typically, modified or synthetic resins are used for manufacturing; they can be produced from natural components with additives or consist of artificial polymers. It is also used for 3D printing.

For thermosetting plastics that only have one monomer, the sole monomer compound is called "resin." For example, liquid methyl methacrylate is generally called "resin" or "casting resin" when it's in a liquid or viscous state before it polymerizes and "sets." The subsequent polymethyl methacrylate is often renamed acrylic glass or just acrylic.

Sometimes when you make resin jewelry or epoxy art, you may find that the surface is uneven. This can be a resin edge, unevenness, or gap (also known as a "fish eye") in the resin surface. The good news is that you can sand the resin after it's fully cured for an even finish.

Here's how to sand the resin smooth:

Materials you need:

*Wet or dry sandpaper from 400 to 1000 grit

* A hard, flat surface on which to place the sandpaper

*water

*Dust coverBefore you start, put on a dust mask if you don't want to breathe resin dust.

1. Place the sandpaper, with the sanding side up, on a hard surface.

2. Then, take your resin charm, craft, or jewelry and submerge it in water.

3. Hold it firmly and sand it back and forth on the sandpaper. Change directions several times. For example, if you're sanding a resin bracelet, go "north to south." Then, "from east to west." You also need to sand in a figure-8 motion.

4. Once everything is smooth and even, choose the next finer sandpaper. Continue sanding as in the previous step. Gradually use finer sandpaper. Otherwise, you won't be able to remove all scratches from previous papers.

5. Continue sanding until the trim is as smooth as you want.

You can also use the Dremel tool to sand resin.

But the problem is that a Dremel tool takes off resin quickly. If you aren’t careful, you’ll have divots in your resin that you’ll have to repair. Or fill it in with more resin.
