How the heck do you properly paint engraved lines?

So Im designing these Ukuleles, they are so perfect, until I need to paint the damn things. I just cant ever get it right…

  1. I painted the initial color
    2)Taped then engraved
  2. Dabbed paint with a brush into the engraved
  3. Took tape off, this was the result…

Still just looks not great. Anyone have any advice?

You will probably never get great results, especially engraving on plywood. The paint will soak in in some places and remain on the surface in others. I have had better luck with spraying a few coats of a clear sealer before painting, but they are still less that stellar.

Damn…you think better wood would work better?

Have you tried just scoring the masking, weeding the image and spray painting? If you are going to varnish/shellac the finished piece it would give you great results.

So youre saying score instead of engrave? What did you mean by weed the image?

Weeding the masking involves removing the parts where you want painted


This is an example of both scoring and engraving. The sign was first painted white and then masked. The text was scored and the graphic was engraved. After it was scored and engraved I removed the tape from the text and painted the entire thing black. When everything was dry I removed the remaining masking a clear coated the whole sign.

This is also a pretty good candidate for a veneer/engrave inlay. You can do pretty fine details that way. I’d use raw veneers, not the proofgrade stuff.

Inlay in general looks really classy, really steps the design up. You could do it with solid-colored acrylic too, as a through-cut inlay. This is a slightly tricky through-cut inlay because it’s got shapes inside other shapes, but it’s attainable. Done well it would make people stop and gawk.

A engrave/powder inlay would also work well and is much less technical to pull off. Check out previous projects involving mother-of-pearl and glow powders. It can work so well.

@evermorian took that concept and really knocked it out of the park with these:

What kind of tape do you use? Yours looks perfect.

Spraying or brushing clear poly on after engraving will help prevent bleed-over into adjacent wood fibers. You have to experiment to find what works best for your material.

Just about any of the generic masking will work just fine. If you’re engraving then painting on pre-masked, pre-finished Proofgrade woods, that works just great as well.

I still love that piece.

Ditto to spray paint, but if that’s not an option - seriously water down water paint you are using to get it to fill the lines in evenly.

Also, I may have missed it in here, but has anyone recommend @evansd2 glue masking technique?

Not sure I’d recommend the wood glue technique on anything porous. Works well on tile, plastics, and acrylic, but I don’t know how you’d get it off of rough stone or wood.

As for traditional masking and Baltic I think you’re never going to get a great result with any paint that the fibers will absorb. Sealing the wood first is the way to go.

That said if you really want to keep trying traditional masking and can’t get the masking to hold well enough you might like this post about getting a better masking seal on woods like BB ply.

I mask with 12" paper based transfer tape and roll it out with a 6" hard rubber brayer to eliminate air bubbles and ensure optimal activation of the adhesive.

Acrylic markers were the closest I got haha!

Here is my technique. I use shellac to seal the wood from the acrylic. Using a brush, work the acrylic into the engraving making sure the bottom of the engrave is covered by the paint, wiping the excess with a damp paper towel as I go along. Since the acrylic drys very quickly there will be some left on the shellac surface. Using a cabinet scraper, scrape the shellac surface enough to remove the excess acrylic. It is not necessary to remove all the shellac, just enough to clean off the excess acrylic. Finally do a resin pour over the entire surface. The result is a beautiful, shiny surface.

It takes a bit of time and effort but the appreciation from those I give the gifts to is well worth it.

Any slow-cure gloss resin will give the same results. You can get it for $25 at The Home Depot.

I just use WBPU, Minwax “polycrylic”. Side-by-side I can tell a difference, but nobody I’ve ever made something for can.

I have used “Amazing Clear Cast” casting resin by Alumilite but I am sure there other brands that work well.

You can get that one at Wally, Michaels, etc.

It’s a little more expensive per oz than the stuff at Lowes/Home Depot, but for small/one-off projects it works just as well.

I’ve worked with epoxy resin for almost 30 years. There’s nothing magical about any of them. Just that slow-cure generally dries to a harder, glossier finish than fast cure varieties.
