Many are amazed at the beauty of jewelry made from epoxy resin. Correct and exact observance of all technological stages in their manufacture allows you to get beautiful and unusually effective jewelry. But often even more experienced craftsmen produce products with visible defects, they can be uneven, with streaks or scratches. Grinding the models, and then further polishing will allow you to get the highest quality craft, pleasing with its beauty.

Peculiarities

Many craftswomen are engaged in the manufacture of epoxy resin jewelry. When removing the finished trinket from the mold, a groove often remains on it due to the decrease in the size of the epoxy when it solidifies. A defect in the form of streaks or streaks, as well as build-ups, may appear on the product. The presence of such defects requires careful additional processing of an uneven surface. Carry out grinding, and then polishing in the presence of the following defects:

• if there is an excess of fill in the product;
• if there are scratches;
• when chips appear;
• when the edges protrude beyond the form;
• if there are sharp edges or depressions.

Even if there is a serious defect, you can correct the situation by sanding the product, and then applying an additional layer of epoxy resin to it. At the final stage, the model is polished to give the decoration a complete look.

Tools and materials

Epoxy jewelry is processed manually or mechanically.

For the manual method, take the usual tools in the form of a nail file, sandpaper and a trowel. This method is suitable for fine jewelry work, when making delicate jewelry. It is also advisable to have a magnifying glass or lens - their use will allow you to do the job flawlessly.

For large products, use:

• rough sandpaper;
• dremel (an instrument with a rotating rod);
• a milling machine used in a nail service.

Those who are engaged in making jewelry at home should pay attention to the dremel. This small portable tool has a rotating part . Dremel attachments are used for engraving, they have different sizes and diameters. This is a fairly powerful device, but when working with it, there is a risk that small parts may be knocked out during operation. Moreover, the device has a high speed, which often leads to hand injuries. Use it to drill holes for fasteners.

The milling machine is also successfully used for work . In principle, the device is similar to the previous version, but with a lower number of revolutions per minute, so it can be used to grind smaller objects.

Another tool used for polishing is a resilient foam disc that is attached to a rotating tool. The diameter of the discs can be very different, from 10 mm to 100 mm.

Disks are rubbed with GOI paste before work. This composition was developed and patented in the Soviet Union for polishing various lenses, objectives, mirrors. It is still used all over the world.

Apply GOI paste to rub the surface of the discs. The color may vary depending on the degree of abrasiveness. The most abrasive pastes are light green in color. A darker paste is used to make the products look specular. Grinding of products is carried out with a paste of green and gray colors.

How to polish?

In order for the product to have a finished look, it is manually brought to the optimum condition. In this case, a dusting file, fine-grained sandpaper, as well as foam rubber and polish are used.

Before starting work, it is important to degrease the surface to be treated so that there are no fingerprints or paste residues on it . Without this step, it will not be possible to polish the epoxy to a shine.

The technique of polishing the product includes several stages

1. Shake the jewelry out of the mold and examine it from all sides. If there are major defects, the processing of the product will be rougher. This work is best done using a high speed polishing machine. This will quickly eliminate defects in the form of build-ups and waves, and make the decoration smooth.
2. At this stage, the products are given transparency by polishing with a smaller abrasive. To do this, use special fine-grained circles and pastes designed for polishing cars. A paste is applied to a clean, dry circle - this will eliminate the obvious and smallest defects.
3. The use of polish makes it possible to obtain a very smooth and transparent surface of the part.
4. After going through all the stages, the craft should be varnished, which will protect the product not only from exposure to UV rays, but also from the appearance of yellowness.

In the event that it is not possible to use special tools for work, you can do this with an ordinary manicure set. Using it, you need to cut down all the irregularities. After that, the surface is sanded, continuing to process with sandpaper and water.

Then a little polish is applied to the cotton sponge . The product is rubbed into the product until its base becomes transparent. For a complete look, you can use a water-based parquet varnish. You can also take gel polish, and after applying it, the craft is dried under a UV nail lamp.

Safety engineering

When working with epoxy, safety precautions must be followed. This is a rather harmful material that retains toxicity for up to 8 hours - this is the time that is needed until the composition is completely dry. Any processing or drilling of the product should be carried out only after this.

• When processing products, it is worth preparing the workplace in advance by covering it with film.
• For a large amount of work, wear a protective suit, as well as a scarf or hair cap. Since a lot of dust will be generated when grinding parts, it is recommended to work in a special respirator with a dust filter.
• For eye safety, it is advisable to use special goggles. In their absence, do not bend low to the material so that the resulting dust does not get into the eyes.

After finishing work, it is necessary to remove all tools, clean clothes. The room where the work was carried out must be ventilated.

Recommendations

Adhering to the recommendations of experienced specialists, you can grind and further polish epoxy resin products without any problems. So that in the process of work you do not have to deal with the correction of obvious defects, it is imperative that all work be carried out carefully, without violating the technology.

• When pouring epoxy resin into molds, this should not be done abruptly, slowly. Thanks to this uniform filling, you can not be afraid of the appearance of grooves.
• In order for the surface to be shiny, it is advisable to use molds with glossy walls. The matte base of molds is able to make the very shape used in work matte.
• The work table should be aligned horizontally - this will allow the material to distribute without dripping.
• Two types of pastes are suitable for polishing. You can use an abrasive and non-abrasive paste. The first option is best used for polishing. This product will prepare the surface for the application of the non-abrasive paste. When working with a non-abrasive paste, the finished product will turn out to be glossy. When choosing this option, it is better to use foam pads. Pastes suitable for epoxy models are available at auto dealerships.
• When working with a dremel, it is important that the number of its revolutions per minute does not exceed 1000 revolutions. If you do not adhere to this, the product may begin to melt.

For beginners, epoxy may not be easy to work with. But having studied the basics of work, as well as listening to the advice and recommendations of specialists, you can safely start creating and making not only original epoxy jewelry, but also more bulky products.
