I have a nickel sized, 1/16” deep tearout in a maple table top. I’ve sanded it out partly but fear it will be a ton of work to sand down the full diameter required to hide the mark (I’ve done about 2” this far) . I will be staining the maple with a relatively dark TransTintdye. I am thinking of leveling it out with epoxy prior to spraying the dye stain Arm-R-Seal topcoats. Thoughts? I am hoping given the dark dye (Vintage Maple) the blemish won’t be too noticeable? Would appreciate if someone can confirm the dye OVER epoxy (West Systems) is safe. I figure it would be better to dye it all at once rather than have dye in the epoxy also.

I’ve never been able to cover an epoxy repair with any kind of stain or dye. They never absorb like the wood does and so they show up as a flaw. Can’t be planed out? Also a scraper might be able to take it out and keep the wood level. Good luck.

For what it’s worth, I’ve had good luck with the Titebond wood filler. It takes stains pretty well (as always, test before using on a finished piece).

I should add that I am going to use the Charles Neil blotch control on this table. So I guess I need to know if the CN product can bite into the epoxy.

Someone correct me if I’m wrong, but I don’t think much of anything will “bite” into cured epoxy (not the stuff I’ve used, anyway). Mr. Neil would be the one to answer that, of course. I don’t know how his excellent blotch control would work in that situation.

You could try making a dutchman on a piece of scrap and see if you like the result. You will need a piece of stock that matches the table’s grain as closely as possible. Also, if you use an irregular shape it will be less noticeable. Once the top has been routed out and the slightly thicker matching piece glued in, plane, scrape or sand it to be flush with the top.

Once you put the epoxy on the wood it will no longer accept any kind of dye.

Dye it first then stain the filler to match or slightly darker. Matching the tone is more important than matching color. Try a shellac stick or maybe a dutchman like Art suggested. Might want to practice on scrap first.

cellulose-based fillers would work a lot better than epoxy. I think DAP makes something called “plastic wood”, comes in a small red tin and it’s nasty to work with but it works great. It’s basically wood fiber in some type of acetone-based binder/adhesive and it sets up in minutes and cures quickly, it can be sanded and stained, although since it’s an artificial filler putty, it’s very uniform so if the wood around it has a lot of figure, you would notice regardless of how well the stain matched.

Good advice here.

I have played with dying/staining repairs slightly lighter
and then dry brushing acrylic model paints to imitate grain
and tweak the color.

A knife or awl can be used to make grain lines if
needed to get color to take.

This stuff can make you crazy because it’s such a
small thing. Apply craftsmanship and keep at it until
it’s right and you’ll get a good result. The major
mistake I’ve made with color repairs is fooling myself
that it’s a better match than it is. Still, a uniform
topcoat does distract the eye and hide a lot of sins,
something guitar builders know well.

Epoxy can be made to take stains by mixing in fine wood flour—in your case, maple, obviously. But it will be very difficult to get a perfect match. I’d suggest several test batches before committing. Sand or scrape them before trying the stain or dye. Fine sanding dust is the right texture, especially with a fine grained wood like maple.
