How to Fix Yellowed Resin & Keep It Crystal Clear Longer

Resin is a stunning material for home decor, jewelry, and handmade crafts—but over time, you may notice it turning yellow. At BreakWooden, we know how frustrating this can be, especially when you've put your heart into a piece. Here's how to fix yellowing resin and prevent it from happening in the future.

🔍 Why Does Resin Turn Yellow?

There are several common reasons:

• Exposure to sunlight and UV rays

• Low-quality or expired resin

• Incorrect mixing ratios or incompatible pigments

• Poor storage: hot, humid, or unsealed environments

🧼 Quick Fixes for Light Yellowing

If the yellowing is only surface-level, try:

1. Wiping with isopropyl alcohol to remove surface haze

2. Washing with warm water and mild soap

3. Spraying a clear UV-resistant sealant like Krylon or polyurethane

4. Displaying your piece in shaded areas, away from direct sunlight

🛠 How to Restore Heavily Yellowed Resin

For deeper discoloration:

1. Sand with fine-grit sandpaper (400–800 grit)

2. Buff with polishing compound and a soft pad

3. Apply a fresh coat of clear resin or UV-resistant sealant
   → This process helps remove yellow layers and restore clarity and shine.

💡 Pro Tips to Prevent Future Yellowing

• Use high-quality resin with built-in UV protection

• Store your resin products in cool, dry places

• Avoid using pure white colors, which show yellowing more clearly

• Finish your pieces with a protective clear coat after curing
