Basement Bar with Butcher block top
I have just finished building my first bar in my basement. I have a 1.25" Birch butcher block im installing as the top which is uncut and unfinished now. I know there are lots of debates on how to finish etc.. My dillema is that 1) the Butcher block is in the basement (humid but can be controlled with dehumidifier) and 2) The butcher block has an over hang of 11" in front and 3" on the inside, I am going to be welding together some decorative L-brackets to give extra support but I was worried a Polyurethane coat would crack with the overhang expansion. I am not sure how I should finish.
Its a basement bar, not gonna be cutting anything on it or eating anything off it, I just dont want any issues down the road. Waterlox is not an option as I am in Canada and it costs a fortune to get it here.
Also curious what brands of Polyurethane you reccomend and curious what the difference between the polyurethane "for floors" is compaired to the regular stuff if it is suggested to go down that route.
Thanks alot for any help or suggestions.
