Pouring epoxy

[Tom Bussey]

Asking for a friend who had an emblem cut into a piece of wood on a CNC He wants to pour Epoxy into the cavity. Do you seal the cavity before pouring. The wood is hard maple and the epoxy is black

[Jim Becker]

It's a best practice to seal before pouring anything to fill, especially if there's a colorant involved. You don't want that colorant to soak into the surrounding grain. You can use wax free shellac or clear epoxy for the task.

[Tom Bussey]

Thank you for your answer. It paralleled my thought on the mater. I had to really sand down the friends work because it soaked into the surrounding grain.

You will have a much better time with final finish if you do seal them. When I rush and dont I usually get pin holes that around the epoxy/wood boarder. These can be filled with CA but are quite annoying. A faster clear drying epoxy works well.
