How to Avoid Lines and Streaks in Your Epoxy Resin Artwork

If you are a DIY enthusiast or a professional artist, you may have encountered the frustrating issue of lines or streaks appearing in your epoxy resin artwork. These imperfections can detract from the overall beauty of your creation. However, with a few simple tips, you can ensure a smooth and flawless finish every time.

Using Resin Mix Within the Pot Life Time

One common reason for lines or streaks in your work is not using the resin mix quickly enough. When the epoxy resin is exposed to air, it begins to cure, and as a result, it becomes less fluid and more difficult to work with. This can lead to uneven spreading and the formation of lines.

To avoid this issue, it is crucial to apply the epoxy resin within the pot life time, which is typically around 40-50 minutes. If you attempt to spread the resin mix after this time frame, it can leave textural lines in your artwork. Therefore, it is essential to plan your work accordingly and ensure that you have everything prepared before starting the application process.

Preparing a Flat Surface

Another factor that can contribute to lines and streaks in your epoxy resin artwork is an uneven surface. Before pouring the resin, make sure that the surface you are working on is completely flat. Any bumps, lines, or imperfections below the artwork or mold can show through in the finished piece.

To achieve a smooth result, take the time to prepare your work surface properly. Clean it thoroughly and ensure that it is level. If needed, use sandpaper or other suitable tools to remove any unevenness. By starting with a flat surface, you will minimize the risk of lines and streaks in your final artwork.

Avoiding Movement During the Curing Phase

During the curing phase, it is essential to avoid moving your work as much as possible. Any disturbance or shifting of the resin mix can result in lines or uneven layers in your artwork. To prevent this, pour the resin mix in the area where you intend to leave it to cure.

Choose a location where your artwork can remain undisturbed for the entire curing period. This will allow the epoxy resin to settle and level naturally, resulting in a smooth and flawless finish. Avoid touching or manipulating the resin during this time to ensure the best possible outcome.


Lines and streaks in epoxy resin artwork can be frustrating, but with the right techniques, you can easily avoid these imperfections. Remember to use the resin mix within the pot life time, prepare a flat surface, and avoid moving your work during the curing phase. By following these guidelines, you can achieve stunning results and create resin art that is free from any unwanted lines or streaks.
