Epoxy resin is an incredible medium for creating stunning artwork, furniture, and handmade crafts. However, beginners often encounter problems like air bubbles, cracks, sticky surfaces, and poor adhesion. These mistakes can ruin an otherwise perfect project!
In this guide, we’ll cover the top 5 most common epoxy resin mistakes and how to avoid them for a flawless, professional finish. 🚀
🔹 1. Air Bubbles in the Resin 💨
❌ Problem: Tiny air bubbles trapped in the resin can create an uneven or cloudy finish.
✅ Solution:
✔️ Mix the resin slowly to prevent excess air from being introduced.
✔️ Use a heat gun or torch to pop bubbles after pouring.
✔️ Work in a warm room (20-25°C / 68-77°F)—cold resin traps more air.
🔹 2. Sticky or Soft Resin After Curing ❌
❌ Problem: Your resin remains sticky or rubbery even after 24-48 hours.
✅ Solution:
✔️ Measure correctly—Always follow the correct resin-to-hardener ratio.
✔️ Mix thoroughly for at least 3-5 minutes, scraping the sides and bottom of the cup.
✔️ Ensure proper curing conditions—Cold temperatures or high humidity can affect curing.
🔹 3. Cracks & Fissures in the Resin 🕳️
❌ Problem: Resin cracks during or after curing.
✅ Solution:
✔️ Avoid pouring too thick—Most resins have a maximum pour depth (check the label).
✔️ Use a deep-casting resin for thick layers.
✔️ Let the resin cure slowly at room temperature to prevent thermal shock.
🔹 4. Resin Doesn’t Adhere Properly to the Surface 🔄
❌ Problem: The resin peels off or doesn’t bond well to wood, metal, or other surfaces.
✅ Solution:
✔️ Sand & clean the surface before applying resin for better adhesion.
✔️ Use a primer or sealing coat on porous materials like MDF or wood.
✔️ Avoid oily or dusty surfaces—Clean thoroughly before pouring.
🔹 5. Uneven or Cloudy Finish ☁️
❌ Problem: The resin dries with an uneven texture, streaks, or a cloudy appearance.
✅ Solution:
✔️ Work in a dust-free environment—Cover your project while curing.
✔️ Use high-quality, non-yellowing resin for crystal-clear results.
✔️ Apply a final topcoat if the surface feels uneven.
