Roll out the vapor barrier material over the entire concrete floor, ensuring it covers the entire surface. Use a utility knife to trim the vapor barrier to fit the dimensions of the room. Overlap the seams of the vapor barrier by at least 6 inches and seal them with tape to create a continuous barrier. Secure the vapor barrier in place using adhesive or tape around the edges to prevent it from shifting.
