You completed your epoxy art or resin tumbler. And you’re SO EXCITED — until you see dimples. Not on your face but on your resin surface. Whatever you call these resin dimples — divots, holes, voids, fish eyes, glazed glitter skittle — they don’t have to wreck your creativity. Here are three steps on how to fix dimples in epoxy resin.
Step 1: Figure out why the resin dimples happened.
Those who fail to learn from their resin dimples are doomed to repeat them. So you’ve got homework. Review the five answers to the question why does my epoxy have dimples.
Then, make sure you know what happened so you know how to avoid the fish eyes when you make your next piece of resin art.
Step 2: Figure out how deep your resin dimples are.
If your divots are one-sixteenth of an inch or less, mix and pour a new flood coat of resin. Make sure your resin surface is clean and that you use the right amount of a doming resin. Doming resin self-levels and evenly coats a surface. This epoxy resin type self-levels to a one-eighth-inch. It will even itself out over the entire surface if your holes are 1/16 inch or less.
💡 Pro tip: If you don’t know how much epoxy you need, this resin calculator does the math for you. It’s important that you use enough epoxy resin as a part of knowing how to fix dimples.
Step 3: Sand your surface if your dimples are one-eighth inch or deeper.
Since doming resin levels to one-eighth of an inch, you need to sand the epoxy resin surface so the dents are less than one-eighth of an inch deep. This allows the resin to cover the surface evenly when you apply another flood coat.
⭐️ BONUS: If you haven’t sanded resin before, here are my resin sanding tips.
💡 Pro tip: When pouring a second (or more) layer of resin, it may not fill to the edge as well as it did with the previous layer. Create a tape dam around the piece with masking tape or painter’s tape to make sure the resin gets to the edge.
Ta-da! You just learned how to fix dimples in epoxy resin.
