Your Guide to Fixing Common Beginner Resin Mistakes

Last updated

At Carved, we are passionate about using epoxy resin to make gorgeous, functional pieces like our wooden iPhone cases. Part of what makes resin so exciting to work with is that it can be both simple and challenging.

Suppose you're venturing into the world of epoxy resin. In that case, we can help you avoid the most common pitfalls by sharing what our experience has taught us. By mastering these techniques, we can reliably turn out one beautiful wood phone case after another. So, let's look at some common beginner problems and how to solve them. Hence, your future epoxy projects are nothing short of perfection.

Common Mistakes Made by Beginners

Diving into your first resin art project can be truly exciting. Yet beginners tend to make a few common mistakes. We're here to help you avoid these common missteps and improve your resin crafting skills.

Unclean Workspace or Surface

Unclear workspaces, materials, or tools can make your environment safe and positively impact your finished project. Ensure your workspace is impeccably clean to prevent unwanted particles from hindering the finishing of your project. Especially if you're working with resin and wood, make sure your work surface is free from dust and level. Propping up and taping the edges of your project can help prevent drips and ensure even surfaces.

Inaccurate Measuring & Mixing

One significant issue beginner resin artists face is accurately measuring and mixing the resin and hardener. An incorrect mix ratio can lead to a sticky, cloudy, or uneven cure. To avoid this, it's essential to pay extra attention to the instructions of your particular product, as different brands may have differing mix ratios. 

Measure the resin and hardener using measuring cups specifically designed for fine measurements. Then, mix the substances for several minutes, scraping the sides and bottom of the container to prevent unmixed streaks. When you stir the mixture, do it slowly to avoid incorporating excess air, which leads to bubbles.

Choosing the Wrong Resin

Selecting the correct resin is crucial for the success of your project. Different projects require specific types of resin — for example, some are formulated for deep pours, while others are UV-resistant. Using the wrong resin can lead to failure, so constantly research to ensure you use the resin that matches your project requirements.

Ignoring Environmental Factors

Temperature and environmental factors can significantly affect the curing process of your resin. Resin tends to cure best in warmer, less humid conditions as it becomes thinner, making it easier to handle and remove air bubbles. Conversely, the resin can become thicker and less manageable in colder temperatures. Work at an ideal temperature to avoid bubbles and cloudy resin. 

Tools like heat guns or torches can be your best friends if you encounter bubbles. Applying heat to the surface of your resin piece a few minutes after the pour will help to pop those surface bubbles and better ensure a smooth finish.

Allowing Moisture Contamination

Avoid moisture contamination by ensuring all your tools and additives are completely dry before bringing them into the resin. Moisture can interfere with curing, causing the resin to harden improperly. It could also lead to warped areas or mold in some cases.

Using Excessive Colorants

Be cautious with the amount of dye or pigment you add to your resin since using too many colorants can prevent proper curing. Some math might be necessary, but you should ensure your dyes take up at most 6% of the total resin volume. Additionally, it's always a good idea to conduct a test pour to check the compatibility of your colorants.

Rushing the Curing

Understanding the curing process is crucial in achieving successful resin projects. Proper curing avoids sticky resin and ensures an even, glossy finish. Always adhere to the manufacturer's curing instructions and then practice some patience. Give the piece the time it needs to be cured entirely so you avoid any mishaps. 

Keep in mind that working with resin requires attention to temperature. Most types of resin or epoxy function within precise temperature ranges for adequate curing. Delving outside these ranges can lead to complications or cause the epoxy to cure faster or slower.

Skipping the Finishing Steps

Sometimes, resin cures with flaws, but scraping the entire project is unnecessary. Sanding and polishing can help adjust uneven surfaces or restore gloss to resin finishes. Start with wet sanding to correct imperfections, then polish to restore the gloss and clarity.

Frequently Asked Questions

What are common mistakes beginners make with epoxy resin? 

Common errors include inaccurate measuring, improper mixing, lack of temperature control, and maintaining an unclean workspace. These can result in issues like stickiness or cloudy resin. In particular, using epoxy resin on wood requires careful preparation (cleaning, dusting, drying, etc.) of the piece of wood to ensure good results.

Do environmental factors affect resin curing? 

Yes, environmental factors like temperature and cleanliness significantly affect resin curing, requiring more or less time and impacting the aesthetics of the final product.

Can epoxy resin be remelted? 

No, you can't remelt epoxy resin once it has cured. Once cured, it transforms into a thermosetting polymer you can't reform by heating. The structure becomes durable, stable, and highly resistant to wear and tear.

How can I fix imperfections in my resin projects? 

Sanding and polishing techniques are effective for correcting flaws in cured resin projects. Wet sanding helps with imperfections, polishing restores gloss, and a UV-stable clear coat provides extra protection and shine.

Can I fix an uneven pour in epoxy resin? 

Yes, scraping and sanding are recommended to fix an uneven resin pour. However, pouring resin evenly from the start is best to prevent air bubbles and ensure a smooth finish.
