Common Resin Problems

1. Resin Is Not Curing

Encountering the frustration of uncured epoxy resin can throw a wrench into the excitement of crafting. Several factors could contribute to this issue, including inaccurate resin-to-hardener ratios, insufficient mixing, or improper environmental conditions.

Fix: The fix for uncured resin often involves assessing the root cause. First, double-check the resin and hardener proportions, making sure they are measured properly.

Thoroughly mix the resin and hardener, making sure to scrape the sides and bottom of the mixing container. If environmental conditions are affecting the curing process, such as low temperatures, try moving the project to a warmer area.

2. Resin Is Yellowing

Yellowing is a common concern with epoxy resin, and it occurs as a result of prolonged exposure to UV light.

When resin is subjected to sunlight or other sources of ultraviolet radiation, a chemical reaction takes place within the material, causing it to gradually adopt a yellowish tint.

This process can compromise the clarity of the resin, altering its original transparent or translucent appearance.

The impact of yellowing varies depending on the type and quality of the resin used, as well as the duration and intensity of UV exposure.

Fix: To mitigate yellowing, crafters often opt for UV-resistant resin or UV-stabilized epoxy resins, and they may also choose to store or display their finished projects away from direct sunlight to preserve the resin’s aesthetic appeal over time.

3. Resin Is Getting Hot

Overheating poses a potential pitfall in the world of epoxy resin crafting, primarily when an abundance of heat is applied, such as through the use of a heat gun or other heat sources. During the curing process, resin will also heat up.

The consequence of this excessive heat is accelerated curing of the resin.

This may introduce unwanted complications like the formation of bubbles within the resin and wreaking the smooth finish desired for projects.

Furthermore, overheating may compromise the structural integrity of the cured resin, potentially leading to cracking or other deformities.

Fix: Turn off any heat guns or other heating devices, and allow the resin to cool down naturally. If possible, move the project to a cooler environment to facilitate this process.

It’s essential to monitor the resin closely and ensure it doesn’t reach a temperature that could lead to irreversible damage.

Resin getting too hot can cause all kinds of problems and we go over the top 10 reasons why resin is getting hot to help you troubleshoot this problem and fix it.

4. Resin has Imperfections

Epoxy resin, despite its transformative and glossy allure, is susceptible to imperfections that can crop up during the crafting process.

These imperfections often manifest as tiny bumps, uneven surfaces, or irregularities, and they can result from factors such as dust particles settling onto the resin as it cures, incomplete mixing, or rapid temperature changes.

Fix: The good news is that many of these imperfections can be remedied with a bit of sanding finesse. Sanding not only smoothens the surface but also helps eliminate any irregularities, providing a clean canvas for a flawless finish.

It’s crucial to start with a lower grit sandpaper to address prominent imperfections and then progressively move to higher grits for a finer finish.

5. Resin Is Causing Paper Colors To Bleed

Discovering that resin is causing paper to bleed underneath can be disheartening, especially when making photo pendant resin jewelry.

This issue arises when the resin penetrates the paper, causing inks or colors to spread and blur. The quick fix involves taking preventative measures by sealing the paper before applying resin.

Fix: For future projects, a proactive solution is to seal the paper before applying resin. Use a clear sealant or mod podge on both sides of the paper and allow it to dry thoroughly before incorporating it into your resin project.

This pre-sealing process creates a protective barrier, preventing the resin from penetrating the paper and causing bleeding. Our article about how to properly seal paper for resin goes through everything you need to know.

6. Resin Is Cloudy

Encountering cloudiness in cured resin can be a perplexing setback, often stemming from inadequate mixing or exposure to moisture during the curing process.

The cloudy appearance arises when the resin components haven’t been thoroughly combined, creating a less-than-transparent finish.

Fix: To remedy this issue, the key is proper mixing. When preparing your resin, take the time to stir the components thoroughly, scraping the sides and bottom of the mixing container to incorporate them evenly.

Work in a dry and controlled environment to minimize the risk of moisture interference during the curing stage.

There are many reason on why your resin is cloudy or turned opaque and we discuss it all in this article why resin is cloudy and how to fix it.

7. Resin Has Seized

Experiencing resin that has seized can be a frustrating roadblock in your crafting journey. Seizing occurs when the resin and hardener react unexpectedly, leading to a thickened, lumpy mixture that is challenging to work with.

Fix: To address this issue, the first step is to remain calm and avoid the temptation to force the mixture, as this can exacerbate the problem.

Instead, try to identify the cause by checking the resin-to-hardener ratio, ensuring accurate measurements. If the proportions are off, attempt to adjust them according to the product’s guidelines.

Resin can also harden up faster when using too much pigments or paint to color the resin.

If seizing persists, consult the manufacturer’s instructions or contact their customer support for tailored advice. In some cases, you might need to check to see if the resin has expired.

The importance of precise measurements and proper handling to prevent this issue in future resin projects especially when adding the proper amounts of colorants to resin.

8. Resin Flowers Have Turned Moldy

Discovering mold on resin flowers can be disheartening, and it typically occurs when moisture is trapped during the curing process. Never use fresh flowers in resin.

Fix: While you cannot fix cured resin, you can make sure not to make the same mistakes next time. Allow the flowers to thoroughly dry before putting them into resin.

We go over all of the proper ways to dry flowers for resin. And if you don’t want to dry them yourself, here are the best dried flower kits for resin that are often used here.

We created a pendant using fresh flowers encased in resin, doing some testing. About 4 months later, we noticed something – mold had started growing inside the pendant.

So it’s super important to make sure your flowers are completely dried. Especially if you are doing a business on preserving wedding flowers.

9. Resin Is Full Of Bubbles

Discovering that your resin is full of bubbles can be a common challenge, but there are effective ways to address this issue.

Fix: Firstly, prevention is key, so make sure to mix the resin and hardener thoroughly but without introducing additional air. Slow and steady is best and try not to lift the stirring stick out of the resin while stirring.

Pour the mixture slowly to minimize air entrapment and consider using a heat gun or torch to remove bubbles after pouring.

If bubbles persist, you might just have to keep checking on your piece, popping the bubbles as they rise to the surface.

Alternatively, tapping the sides of the container or gently stirring with a toothpick can help release trapped air. Our guide on how to remove bubbles in resin has expert tips.

10. Resin Has Dimples

Discovering dimples in your cured resin projects can be a common frustration, often stemming from factors like incomplete mixing, uneven pouring, or environmental conditions during curing.

Fix: To remedy dimples, consider sanding the affected areas with fine-grit sandpaper, starting with a lower grit and progressing to higher grits for a smoother finish.

When working on future projects, ensure thorough mixing, pour the resin evenly, and create a controlled curing environment to minimize the risk of dimples. Read about how to fix resin dimples.

11. Resin Adhesion Problems

When you’re dealing with resin problems, one common hiccup is adhesion. Where the resin doesn’t stick well to certain surfaces, causing issues like delamination or weak bonding.

Fix: Make sure the surfaces are squeaky clean, thoroughly dried, and properly prepped before applying the resin.

If you’re still facing adhesion woes, think about using primers or adhesion promoters as suggested by the manufacturer – they can be real game-changers in getting that solid bond you’re aiming for.
