You keep changing your original post on us and suddenly have new materials for us too consider.Yes it was free, i cut the tree down and bought a bottle of rum for a guy that had a portable saw mill. Its been drying for over 1 year now. It would not really be a spot where it will be getting wet alot, just a breakfast bar area. But it is still a concern weather or not it is durable enough, and what is invoved in fishing it and sealing it for this type of application?
If the pine is really dry. Use it for a countertop. Put a a bar type poured expoxy finish on it and you will be fine and beautiful. If it is not dry in just one year, you will be screwed.
