Full Version: Making Wood darker

Harvey,

On woods needing a darker image I will apply a laser mask material, engrave and spray lightly with a flat black Krylon enamel paint. If you get aggressive and heavy with the spraying it will seep into the grain. I hit it with a couple of very light coats on finished and unfinished woods and don't seem to have any seeping problems.

Harvey,

A trick we learned was to spray a clear coat over the lasered masked plaque then let it dry and then spray the black. We also found the the black paint for plastic works better. It must be a thicker paint so it won't bleed as much.

I know Rawlings engraves bats on site at the ballparks and they apply car wax to the surface of the bat and then laser it and then fill it with black paint. I don't know what the paint is but I think it is a water base paint. They let it dry for 30 minutes and wipe it off it works great with no bleeding into the grains. and produces a stunning look.

Thanks to both.

It is a very light wood and the clear discolors it a bit, (it gets stained with a light stain afterward, but still shows a bit), but does seal the grain from the color. I tried the Krylon black. I guess it needed a much lighter first coat to act as a sealer. Staining it first then filling is not a possibility due to the mask that needs to be burned through with the artwork for color filling.

A latex paint might work far better. It is thicker and might even start to set up as the wood absorbs the water to the grain. A very good suggestion also.

The wax trick is a great one, but the product is totally unfinished and that look is required. A polished surface would not work. The stain is used with the sealer as part of it. That gives a good rustic look and protects it from dirt such as fingerprints.

I have a 75 watt laser and for lettering run it a 10% speed and 100% power and get a dark brown mark on oak and a medium brown mark on maple. Alder I am able to engrave at a much higher speed. I engrave the lettering before finishing and then run it through the drum sander to get the smoke residue off. If I want a really black mark I laser. sand and then put 2 coats of lacquer on and then apply laser darc without relasering.

We've been using liquid shoe polish for some time now and it works great. You have to be sure that the wood you're using isn't too soft or else it will seep into the veins of the wood. We only color-fill wood plaques made of walnut, cherry or something of the like, never red alder. Alder is a very soft wood and normally doesn't require color fill like the other plaques do (it's also one of the woods that will soak the polish into the veins of the wood). I can agree with Pete on the unfinished wood, but we've actually never tried it ourselves either.

Shari,

Finished, or unfinished, I think?

Try "Sumi Ink". It is the stuff that is used for Japanese Calligraphy. But the same caution applies as with other inks...very porous wood will absorb ink along the edges.

I have also been told that hard floor wax will work. I learned that in a class that I took.
Good luck! all of the suggestions are good. I have used black polish also and it works good if the wood is not soft.

Many thanks to all for all the suggestions. I will be trying them all! If I discover something else, I'll be sure to share. I just love this forum. It seems there is nothing someone hasn't already done or tried. You are all great inspiration.
Thanks again,
Shari
