We have elongation properties in our formula to make it possible to pour over a substrate that is expanding and contracting, like wood slabs. Wood slabs shrink and swell a ton, old laminate countertops that have flexible overhangs need a coating that will flex with the movement, and so on. Most epoxy gets quite brittle with age. Our product will give slightly to allow for this movement. With that said, our hardness is still enough that it allows for polishing (if epoxy is too soft it won't shine again when polishing). This balance is important. Objects will leave impressions, but the impressions will come out at room temperature once the object is removed because the epoxy has "memory." It will level back! To expedite this you can apply a blow dryer to the area. As the material continues to cure it will become harder but it's designed to retain some of this quality so it makes it possible to pour over wood and laminate surface. You'll want to make sure also that your epoxy is curing for the full 30 day cure time (the impressions will not be as prevalent then).
We believe our formulation is second to none for the purposes we show on our videos! Some of the best feedback we get is from craftsmen, contractors, and artists who have extensive experience with resin and they absolutely love our formulations. We take feedback very seriously and appreciate it, this is why we never stop thinking of best practices. I hope this helps, please feel free to take advantage of our support and thank you for your continued input. Please remember it's always a great idea to start with a small project to get a good understanding of the process. Our epoxy basics page is a great resource as well. You Got This!
