I believe that board is made under the trade name Masonite. You can find it not in flooring but in the bathroom wall boards. It comes in a variety of pale colors and white, both very glossy and textured. Its 4'X8' and is about 1/8th inch thick. The back side is brown as its sort of a processed pasteboard. It may not seam very well as there are joint trim strips used in its intended application. Butted against each other the seams might give you troubles. That's what Post Processing is for, right?
