You have made the most fantastic color combinations and design on your art canvas or countertop only to find after the resin cured, you have holes and dents in the resin surface. These marks, also known as fish eyes in resin, can happen for several reasons.
When this happens, you may find yourself asking what can you do to fix holes and dents in resin.
Here are three steps you need to take to fix fish eyes in your resin surface:
Step 1: Determine why the dents and divots happened.
If you don’t know why they occurred, you are likely to repeat them. I discuss five reasons in this article, why there are holes and dents in your resin surface. Make sure you know what happened, so you know how to avoid them moving forward.
Step 2: Figure out how deep your holes are.
If your divots are a minor depth, like 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 an artwork resin. If you don’t know how much resin you need, this resin calculator does the math for you. An artwork resin self-levels to a one-eighth inch depth, so it should even itself out over the entire surface if your holes are shallow.
Step 3: Sand down your surface if your holes are one-eighth inch or deeper OR plan on multiple pours.
Since artwork resin wants to level to one-eighth of an inch, you will need to sand the artwork surface so the dents in your resin are under one-eighth of an inch. This will allow the resin to cover the surface evenly when you apply another flood coat. If you haven’t sanded resin before, here are my resin sanding tips.
I do not like sanding resin, which is why I share another option of applying multiple flood coats of resin. Of course, this option costs more, but I find it’s easier for most people to get done. You simply need to decide if you want to spend your time sanding or spend your money pouring more resin.
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. You may want to create a tape dam around the piece with good quality masking tape or painter’s tape to make sure the resin gets to the edge.
Hopefully, by the time your resin cures the next time, you won’t need to ask yourself how to fix holes and dents in resin.
