Highly sought after in many fields, epoxy resin offers numerous advantages. Extremely durable, easy to maintain, offering multiple customization possibilities, and providing thermal and acoustic insulation, this type of resin is becoming increasingly popular. Used in industrial environments, epoxy has also found its way into many private homes, where people appreciate not only its intrinsic qualities but above all its aesthetics. Fully customizable, and when worked in a certain way, this resin can also provide a highly glossy finish for a timeless, design-oriented result. In this article, our specialists explain the techniques you can use to make your epoxy resin shine.

All the methods for making epoxy resin shine

Some people prefer a matte finish, while others opt for a glossy look. If you fall into the latter category, you should know that there isn’t just one method, but several ways to make epoxy resin shine. Depending on the size and regularity of the resin surface, you can choose a manual method, use an electric sander, or even a drill.

Prerequisites

Regardless of the method used, before starting the glossy finishing process, it is first necessary to sand the surface you want to work on. This initial sanding is usually done by hand and is known as “wet sanding.” The more advanced the sanding process, the finer the grit of sandpaper you should use, while keeping it wet throughout. Sanding should be carried out in circular motions, with particular attention paid to the edges. These areas must be treated carefully to avoid removing too much resin. Corners should be sanded with very light pressure to prevent damage. Finish by wiping away any excess water remaining on the surface. You are now ready for polishing.

Manual polishing with abrasive paper

Hand polishing is generally preferred for making small objects shine or when dealing with complex shapes. In such cases, an electric sander or drill does not provide sufficient precision. To polish epoxy resin by hand, equip yourself with a cork sanding block, polishing compound, a cotton or linen cloth, and a little water. Start by applying a small amount of polish directly onto the cloth and lightly dampen it with water. Place the cloth on the cork block and rub the surface to be polished using slow, circular movements. Continue until the desired level of shine is achieved.

Applying a finishing coat of epoxy resin

Applying a finishing coat of epoxy resin is another manual technique that avoids polishing altogether. Somewhat delicate to carry out, this method consists of applying a thin layer of epoxy resin to the surface. It can be applied with a brush or by pouring. This technique requires certain precautions, particularly during resin preparation, as the resin should have a texture similar to honey. When used correctly, this method aims to create a mirror-like finish on the surface.

Making epoxy resin shine using a sander

Using a sander to make epoxy resin shine is a common and popular method for large surfaces. In most cases, a random orbital sander equipped with a polishing pad is used. This type of equipment allows you to polish epoxy resin effortlessly and achieve excellent results—provided it is used correctly (not too much pressure and smooth, regular circular movements). Depending on the intensity of polishing, you can obtain a more or less glossy surface.

Making epoxy resin shine using a drill

As surprising as it may seem, it is also possible to make epoxy resin shine using a drill. Better suited for small surfaces, a drill is an effective alternative to a traditional sander. With a polishing attachment fitted to the drill, epoxy resin can be polished quickly. To achieve a nice glossy finish, it is recommended to use a flannel polishing pad and apply the polishing compound directly to it. As with sanding, care should be taken not to apply too much pressure on edges to avoid deforming the surface.
