I am sure that there have been many posts on the topic, but I thought that I would ask anyhow.
I am ready to finish an end grain slab from a maple tree. What should I use for finish? I was looking at Mirror Coat but did not know if that is what I had to use or if I could use, say a wipe on finish. I understand I have to finish both sides equally so that the slab doesnt warp or crack with seasonal humidity changes and excluding cutting boards, I have not had any experience with finishing a slab like this. The wood did crack while it was waiting for me to get to it. The crack has only opened about 7/8 of an inch. I am doing this for a favor and don’t want to get too much wrapped up in it. I know that I either need to fill the crack with epoxy or need to make a tape dam, if I use mirror coat or bar coat, or whatever you want to call it. Anyhow. Please let me know what you think is the best.
