 How can I avoid getting dimples in my art resin surface? Dimples can occur for three reasons. First, if the temperature fluctuates in the room while the art resin is curing for that 24-hour period, you might get some dimples. Secondly, if you get some dust particles in your piece, that can also cause some dimples to happen. And last but not least, if you torch and torch and torch and you actually over torch, you can get dimples from that too. So in sum, make sure that the temperature stays constant in the room while it cures. Make sure you have a cover to cover your piece and make sure that you don't over torch. And if you do all those things, you can avoid dimples.
