How to install (nail down) unfinished hardwood floors
We installed this red oak unfinished hardwood floor in Ellenwood, Ga, in June 2012. The wood is a 3/4 inch thick and 3 1/4 inches wide. After the sub-floor is prepared and the felt paper is laid down you need to nail/staple the hardwood to the sub-floor. The next step would be refinishing the unfinished hardwood floor. Finish the project with needed transitions and shoe molding along the baseboard.
