Q: One visitor asked, "We purchased our 1930's home about a year ago. We ripped up carpet from the entire living room, a connecting hall, dining area and bathroom! Underneath we found red pine flooring all through out, in alternating plank sizes. It was in really good condition. We recently got it completely refinished and stained dark. Unfortunately, the dark stain really shows the gaps in between the planks and all the crumbs/dirt they catch! We asked our floor guy about applying a 4th layer of urethane to help fill them out. He advised us not to since it is softer pine, but I am really considering going ahead and doing it on our own. Our idea is to apply it thick enough to help fill in the gaps, which aren't really all that wide, is this a bad idea!?"
A: Yes, bad idea. Finishes have a recommended spread rate and for polyurethane it is generally 500 feet per gallon. It is not meant to be a gap filler and won’t work as such. You would be better off to use a wood filler in the gaps, then buff the floor and apply another coat at recommended spread rates.
