If I start in the middle of the room, is it harder to reverse back with the tongue facing away?

Hello scott and thanks for your inquiry. When installing a Style Selections Rigid Core Interlocking Luxury Vinyl floor, we would always recommend starting on the longest wall with the tongue side out, and working your way toward the other side of the room as it will always be the path of least resistance to making your flooring installation the easiest. If you start in the middle, it will be a lot harder to back fill because of the angle /drop locking mechanism. We suggest following the installation instructions that are found in each carton, or on the product page of Lowe's website. Thanks again for choosing Style Selections Rigid Core Luxury Vinyl Plank and we wish you all the best with your flooring installation.
