Just FYI, my wood deck is 4x9 feet, 36 square feet. I put on 4 medium-to-thick coats of Minwax Polycrylic. You can be very sloppy with this stuff and put too-thick of a coat on, and it'll still dry up perfectly. Meaning, you can put each coat on in a hurry without having to worry about runs, drips or errors. With good airflow, it dries very quickly. Maybe an hour or two for all four coats.
I used one quart, and had about 1/3 of the quart left over. One quart is $17 at Lowes. I used the Satin finish, for no reason.
Cleanup is easy. Obviously, keeping it swept with a broom helps. Once a year, maybe sooner, I'll use a stiff nylon brush and scrub the floor (without using a lot of effort, 'cause I'm lazy) with soapy water and with a dash or two of degreaser and then wipe it dry with towels. An hour or two later I'll give it another coat or two of the Minwax. Twice I've used the spray can version of the stuff, which also works, but wear a face mask if you do that. I used the entire can each time, which amounted to 3 or 4 relatively thin coats.
But for a straight truck, figure the square footage, divide it by 96 feet (mine), and you'll know how many quarts it'll take. Probably 4 or less.
It's cheap, quick and easy. A rare thing.
How did you know we deliver those hospital exam tables/beds? Have you been spying on me?
