I just installed 400 sq. ft. of this flooring in my family room and adjoining dining area. Like the other reviewer, I use my finish nailer on the starter row and the last two rows. I also used a bostitch flooring nailer which made the job much easier. I found that the planks dented much easier than I had expected, so use the flooring nailer with caution. There was a slight variation in the widths of the planks but the flooring nailer was able to pull them together in most cases. When I noticed this difference in width, I checked each plank before nailing it in place. With careful inspection of the planks and taking care to how I laid out the flooring, I was able to minimize the waste and only ended up with less scrape to fill a five gallon bucket with pieces less than four inches long. Like the other reviewer, it would be wise to open several boxes, lay the pieces out on the floor in piles of the same lengths so that you can select the lengths to install the flooring with the correct separation between joints. I am 71 years young, with a bad back, wrist, and two knees, and I didn’t have that much trouble and I accomplished this project in three days.
