Epoxy Table Hole

This was what we thought would be the end of our table.

There was a tiny hole in the table originally that would be indefinitely sticky so my friend, Coen, thought it was a good idea to cover the whole with more epoxy. So I figured that wouldn’t be very challenging to pour a little drop of epoxy into this hole. Coen ended up using the heat gun. Everything was going well until a bubble formed and blew up the table. I don’t know the exact details but that’s what happened. I came down to the makerspace to see this devastating result. The reason this happened was because a layer on the bottom of this other layer wasn’t curing so it was still sticky and thanks to that hole it connected to the sticky layer and air bubbles would get in and it was bad for the table. This could have been avoided a multitude of ways with not trying to fix the hole, not using the air gun, or just using the right ratio of epoxy the pouring the layer. All in all, we learned from this and I had to correct it.

First we had to cut off all the extra epoxy that was bending to the best of our ability. Then we poured a new layer over the hole. When this cured I sanded it down to the same level of the original layer.

Once it was at the same level I had to sand it down multiple times each time with a finer and finer grit to eventually polish it to see if that would make it more clear.

Then I used the 3 different mixtures in the picture to try and make it more polished.

In the end it looked like this.
