Epoxy Defects On River Table

[Mglidew571]

OK

I built the form, cleaned up the slab and poured the epoxy. The clarity, color and gloss of the epoxy river was more than satisfactory to me.

I waited a week for a good cure and had no problems. I then built the router sled and started to level the surface. My once gorgeous epoxy river developed a bad case of acne in half a dozen spots. See photo. Questions:

1. What did I do wrong?
2. Can this be repaired or otherwise concealed?

Thank You

I think you will need to repour another coat over that…may have been air trapped in the epoxy.

Are those spots hard? If so, then I'd say air. If they are soft, your mixing was probably not sufficient.

Either way, I'd also suggest mixing some more, coat and then reflatten

It may have been bubbles, or the router bit may have had tear out. Really hard to say. I think maybe bubbles.

Either way, a sanding (even with a green scotchbrite, for tooth) and then a shallow pour with squeegee may help. The squeegee will ensure you fill, shallow will help prevent additional bubbles. You may not get the clarity you want (hard to predict from so far away), but it will be better than open gaps.

Thank you. The pocked areas do seem softer than the other areas. I will mix more and pour.

I'm thinking router issue. It was a brand new bit but I played around with rotation speed, feed rate and even feed direction. I got mixed advice on pushing or pulling with surfacing bit.

Like the squeegee idea.

Thank you

Thank you. Could very well be some (impatient) poor mixing.
