Behind Drywall and Other Wallboard
Measure the wall area you want to cover with Visqueen vapor barrier.
Roll out the Visqueen and mark out your measurements on it with a marker and a measuring tape. Leave at least 4 inches of extra vapor barrier for sheet overlap.
Place a piece of scrap plywood or other scrap material underneath the lines along which you want to cut, to serve as a straightedge, and cut along these lines with a utility knife. Press firmly and move slowly to prevent erratic cuts.
Staple the vapor barrier to the wall studs. Use 3/8-inch staples when installing vapor barrier on a wall or floor.
Tape the places where sheets overlap to create a continuous sealed barrier. Use sheathing or tuck tape to ensure a strong bond.
Lay out Visqueen as a drop cloth when painting or drywalling to prevent the paint and drywall compound from coming into contact with your floor.
Use sheets of Visqueen as a vapor barrier beneath hardwood, manufactured hardwood and click flooring to prevent condensation from rising up from the basement or floor below.
Use Visqueen to cover plants and other vegetation you want to protect from frost.
