11 Easy Tips to Remove Bubbles from Epoxy Resin

Bubbles are one of the most common problems in resin art. Careful preparation and pouring can help reduce them.

Tip 1: Mix slowly

Fast mixing introduces more air.

Tip 2: Scrape the cup

Mix the resin thoroughly.

Tip 3: Keep resin at a suitable temperature

Cold resin can become thicker.

Tip 4: Prepare detailed moulds carefully

Small areas can trap air.

Tip 5: Pour slowly

A controlled pour helps minimise trapped air.

Tip 6: Don't overfill

Follow the recommended depth.

Tip 7: Inspect the surface

Look for bubbles before curing.

Tip 8: Use suitable heat carefully

A heat gun can help with surface bubbles.

Tip 9: Don't overheat

Excessive heat can damage resin.

Tip 10: Protect the curing piece

Keep dust away.

Tip 11: Give bubbles time to rise

Some trapped air can naturally move toward the surface.
