A guy dropped off a slab cross section he picked up in Arizona. He indicated it is redwood and from all apperance I would agree. Whatever finish I apply it turns the wood black or very dark. Have tried clear lacquer, varnish, danish oil, and poly. Any ideas??

I saw something similar when I was taking a furniture making class. The instructor brought in a piece of oak, and it had a similar dark stain. From what I recall, this was due to minerals staining the wood where there was an injury to the tree. It was always there, but the stain just made it painfully visible. It could also be due to fungi, or mold. I don’t know if there is anything you can do to salvage it, although someone who is better at finishing may know.

I have also had red oak turn sort of blackish when using Minwax Natural stain. Looks neat on some of the boxes and chests I build. So, I now try to pick out the red oak boards that will give me the darker look, with still using a natural stain. I have had customers request the blackened look on red oak on their Hope Chests after seeing some of my work, but while still using natural stain. Everybody has their own tastes on the finished product.

I have no experience with the phenomenon. However, I have a suggestion of something you can try. I know that sanding end grain as smoothly as possible will minimize the amount of finish/stain it will absorb. Try sanding it at least through 220 and then seal it with spray shellac. Then, if you want some color, use gel stain or a glaze. Maybe that will work. Beyond that ???

I kept trying different product and found Benwood Stay Clear, from Benjamin Moore. I think it came out looking pretty good.
