Problem finishing hardwood floors
This is my first time finishing hardwood floors. I sanded the floor with 80 then 100 grit. Stained it with minwax red oak stain then polyurethaned it two times with minwax brand oilbased polyurethane. I followed the directions on the can and waited the recommended 6-8 hours before applying the second coat. The can said wait 72 hours before moving in furniture, I waited 5 days. My problem is the polyurethane is easily scraped off the floor. Is there a sealer or something that I should use? Any help is appreciated. Please be patient with me I'm a newbie.
