How Do You Install A Vapor Barrier In A Basement?
When installing a vapor barrier on concrete floors, a finish floor will need to be installed to cover the polyethylene material used for vapor protection. This covers the unsightly polyethylene while protecting the film from tears. Vapor protection reduces or eliminates moisture buildup in an area. In an average household of four people, 22.5 pounds of water vapor can be produced in a 24-hour period in a heated building. The water vapor is produced from breathing, perspiration, cooking, bathing, dishwashing, and laundry. Using a broom and a dustpan, sweep the concrete floor to rid it of all dust, dirt, and debris. Apply the mastic to the concrete floor per the mastic manufacturer’s instructions. You will most likely need to use a paint roller with an extension pole at the end.

Make sure that the polyethylene overlaps at least four inches at the seams and that the film extends behind
