Carefully roll out plastic sheeting on a solid, clean and dry surface. Do not allow the plastic sheeting to fold or rub against sharp surfaces, which can pierce the sheeting.

Install butyl tape or construction adhesive on the edges of the surface where you will attach the plastic sheeting. Press butyl tape to flatten into position around the entire perimeter to ensure an air-tight seal. Or as an alternative, insert construction adhesive into caulk gun. Cut the tip on an angle with a sharp utility knife. Apply around the entire perimeter to ensure an air-tight seal when dry.
