Our bar has been a multi-year project, starting when Aaron was still in an apartment and almost finished now, in our second house. We finally coated the top of the bar with Enviro-tec Lite, an epoxy resin. It is fantastic. I want to stress that one more time: it is FANTASTIC. It did not go perfectly, but it did go so well that I feel I will be using enviro-tec lite often in the future. I imagine that on a smaller project, it would be a breeze.
It was difficult to try to keep it dust free while we worked (spoiler – we failed a little) but it still looks great. This is what we rigged to allow it to cure undisturbed: a coffee table on top of a dining table, wrapped in drop cloths.
Because of the differences in depth between the grout and the bottle caps, the epoxy isn’t completely smooth on top. There are some spots where it didn’t completely cover the caps, and some random hairs and rough bubbles. We may coat it again, but the coating being a bit shallow gives a nice effect. It feels smooth to the touch, but in reflected light you can see the outlines of all the bottle caps in the slightly uneven coating. It keeps a little of the texture of the uncoated bar, which we liked but was not very durable. We also think it is a nice way of getting a tile look without a tile texture.
