I am finishing a live edged black walnut tabletop. There are 2 knot holes that are 2” in diameter and about 1” deep. A epoxy resin finish was requested. I am not a professional finisher, but from what I remember that seems too thick to pour. Can I pour multiple thin coats, or is there a better method?

Make sure void does not go all the way through. If it does, seal off on under side with filler, dark cailk, tape etc. Fill it in steps to avoid heat build-up. Works for me. Good luck.

Mix your epoxy. Brush on a thin coat. Add sawdust. Use a thin strip of wood to push it into the voids. Don’t be stingy with the saw dust. Add more epoxy. Now you have a bit of a slurry. Completely fill the knot. Removed the excess epoxy from the surrounding wood with denatured alcohol. What a day. Sand. Beautiful!

you can also add rit dye (black) to color the knot holes so that they look more natural

You could also use turquoise or other rocks to fill with for accent!
