How to make things with epoxy resin

Mixing smaller Quantities of Epoxy Resin: 

For art with epoxy resin or for applications with small amounts of resin, there are special cups with a measuring scale. It is also recommended to use spatulas with a straight edge.

Mixing larger Quantities of Epoxy Resin: 

If you want to mix more than one liter of resin and hardener at once, you should use a sufficiently large container in which you can mix the mass evenly for several minutes using a drill with a stirring attachment. 

Drill Epoxy Resin: 

Drilling epoxy resin is not easy because the material is very hard. To get nice holes, it is important to choose the right drill. 

Depending on the number of holes and the money available, you can choose between two materials:

• HSS: High-performance high-speed steel is a cost-effective variant for drilling holes in epoxy resin. However, the material becomes blunt after only a few drilling.
• HM: Tungsten carbide drills consist of about 90 % tungsten carbide and about 10 % cobalt. This makes them much harder and more temperature-resistant, but also somewhat more brittle. For regular use or for drilling several holes, tungsten carbide drills are therefore the far better choice. 

  Sanding Epoxy Resin: 

  You can sand epoxy resin either wet or dry. Wet sanding is usually done by hand, as water can cause short circuits in electric sanders. You will need wet sandpaper and a hard rubber sanding block. The surface is then sanded finer and finer with circular movements from coarse to fine grain. In this way, even sharp edges such as those on tables made of epoxy resin can be broken.

   

  Polishing Epoxy Resin: 

  Depending on the shape, surface and resin used, the surface may appear slightly rough and Matt after the resin has been applied. Polishing the surface helps to counteract this. For larger surfaces, it is best to use a polishing machine with a suitable polishing paste. With this, you can polish the epoxy resin to a high-gloss surface within a short time and according to your taste. 

  For smaller objects such as resin jewelry or casting molds, you can use a drill with a drill stand, leaving both hands free. This gives you maximum control over the polishing process.
