So I’ve got a small problem.

Been working on a box project. Had an image etched onto the top face via a laser, image is some basic graphics and text. The timber is recovered barn oak, a mishmash of red and white oaks really. The plan was to seal it with BLO, couple of layers of super-blonde shellac on top. Pulled this trick off before, looked great on that piece. Pre-finish, panel looked great, smooth, letters were slightly faint but intelligible. All up, looked about like the last one I did like this.

Last night I put the BLO down on my current project. The letters started fading away more as the BLO penetrated. Said to myself “it’s an oil finish. In for a penny, in for a pound now…” so I cleaned up and went to bed, let it do its thing.

This was last night:

This morning I looked in on it and the letters are very difficult to read now. The BLO has evened out the entire panel. Bummer.

I need a way to darken the letters/graphics that won’t creep into the surrounding grain. I’ve done some homework and read where guys are talking about precision ‘spot-application’ of stain with a detail brush, but I don’t think that’ll work here. What’s in my favor here is the etch is deep enough I think I can get away with putting some fine particulate into the etch, blowing away the excess, and shellacing or clear-coat over the top of that. Hopefully my idea makes sense when you see this:

The BLO can’t be pulled back, so I am where I am. I do have the nuclear option of just planing the whole top down to smooth. I’m not above it, but I’d prefer to preserve the graphic if I can.

I’m thinking about using charcoal/charcoal dust. Read some posts on google about wax. I’m interested in other opinions as well, I figure I can’t be the first to have had a finish not turn out the way I wanted. Any thoughts or time you care to share is very much appreciated. Thanks for reading! – Abe

What about painting the top then sanding the paint back? I’m not sure how the BLO will take the paint, but that’s about all I’ve got.

Thought about that too. It’s a good idea and might be where I go after charcoal. I’m going to try out some of these ideas on some scrap, paint is definitely one route. Agree with your point on BLO, not sure how if it will repel or uptake the paint. Give it a couple of days to settle out and I guess we’ll see!

Painting like SuperCubber said is the only thing I can think of after the fact…. Next time put your finish on first then do your etching. Fill the etching with a stain (I like a dark brown or reddish color) wipe it off and let it set for a couple of days then sand it and refinish….The finish on first will keep the stain from bleeding into the surrounding area….Look forward to see how it comes out….

Thank you both for your suggestions.

I went with charcoal. Fished out a couple of briquets, smashed them up to super fine with a 3lb hammer. Put careful measures into the etchings, shook it around a bit to knock the fine stuff down deep into the crevices and places I needed it to be, blew off the excess and results are below.

The lighting is good on the pic above. For an apples-to-apples of this save, here’s the same lighting as original pics:

Appreciate the procedure for next time. Got lucky here, reckon it will be a while before I attempt this fancy-shmancy stuff again. Or at least, until the next paying customer asks for it… ;D

Again, obliged guys. Thanks! – A
