Hi, I filled a knot in a walnut top with total boat epoxy. I waited about a week and then put a coat of boiled linseed oil and then it sat in my shop for a couple of months. I went to take a look at it last night and the epoxy in the knot swelled a bit.
I'd like to proceed with a coat of shellac and then em8000 from target coating.
Any idea why the epoxy swelled? Should I worry about it happening again? I have included a pic but I am sure its hard to see.
