This weekend I’ll be laying down the floor in the basement. I’ll be laying down a dark walnut laminate floor. E first task was to lay down the vapor barrier. A vapor barrier is required when you are laying a floor directly on top of a concrete subfloor in the basement. E barrier will prevent moisture from creeping under and warping the floor boards as the concrete continues to cure. At the suggestion of the fine folks at Lowes I’ll be running the barrier up the edge of the wall and taping it to ensure a good fit. I also purchased an install kit that includes spacers and a tool to snugly fit e corners.
