Faux wood painted floors. Primer floors first. Them use a roller and roll on your paint color of choice(this is house trim paint in greenblack) and while the paint is wet scrape this tool through to make the wood grain. Do one plank at a time. If you don't like the way the grain turned out just go over it with the tool again. I let dry for one day and sealed it with two coats of oil based polyurethane. Let dry for two days and its usable!
