Jane from Sustain My Craft Habit did a Facebook Live in our Resin Crafting Facebook group a couple of months ago to review the top 6 tips to reduce bubbles when working with resin. Check out her video at the bottom of this post for helpful details on each step!
Top 6 Tips for Reducing Bubbles in Your Resin Projects
- Warm bottles of epoxy prior using. Cold resin (or even room temperature sometimes) is almost certain to form many micro bubbles throughout the entire resin pour that will form throughout the curing process which will be impossible to remove. Place the closed containers into a warm bucket of tap water for 20 minutes. The bottles should be warm to the touch before mixing.
- Seal surfaces of any objects prior to coating with epoxy with Ultra-Seal or any clear-drying water based glue.
- When mixing the resin and hardener, mix slowly making sure to scrape the sides and bottoms of the mixing container. If epoxy is stirred fast it creates more bubbles. If bubbles are visible during the mixing process use your stir stick and push the bubbles up against the side of your mixing container to pop them.
- When pouring your epoxy into a mold, pour very slowly and from one side of the mixing cup into one side of the mold.
- After resin has been poured, wait about 10 – 15 minutes and use a propane or butane torch, making sure to keep 6 to 8 inches above the surface. This helps bring the bubbles to the surface. A long arm butane lighter can also be used. Depending on the depth of the resin pour, you can repeat this a couple of times throughout the curing process.
- If bubbles are present in cured piece, use a razor blade to pop the bubbles and create an open cavity. Mix a small amount of epoxy to fill in those holes; let cure for 5 hours then re-flood surface.
