Temporary wall covering
First Claim
1. A flexible barrier between substrates comprising in combination a flexible sheet and a material with an adhesive surface, the flexible sheet having a first face suitable for receiving the material with an adhesive surface so that the material adheres to a first substrate, the first substrate being at a position adjacent an interface of a ceiling and a wall, a series of apertures through the sheet and spaces between the apertures located opposite the first substrate portion, the apertures being sufficiently large in size relative to the spaces so that when the adhesive surface material is placed over the apertures, the spaces provide an adhesive bond between the material and the first face, and the apertures provide sufficient exposure of the adhesive surface through the apertures to the first substrate, the adhesive material being in physical contact with the sheet and being over the apertures so as to effect adhesion of the material to the first substrate, the flexible sheet being extended to a second substrate spaced from the first substrate, the second substrate being at a position adjacent the interface of a wall amd a floor, the sheet having a second series of apertures through the sheet with spaces between the apertures, the spaces being adjacent the second substrate, the material with an adhesive surface being in physical contact with the sheet and being across the second series of apertures such that the adhesive surface opposite the second series of apertures adheres to the second substrate and the material over the spaces between the second series of apertures adheres to these spaces whereby the sheet is effectively secured between the first substrate and the second substrate.

Abstract
A flexible sheet barrier includes a flexible sheet which has a first face to receive adhesive surface from a material being a strip of duct tape. The flexible sheet has a spaced series of apertures along at least one edge of the sheet, and inwardly spaced from the edge of the sheet. When the duct tape is placed over the apertures, the adhesive surface adheres to a substrate on the opposite face of the flexible sheet. The adhesive surface also adheres to the material on the first face of the sheet. This effectively provides a bonding of the flexible sheet to the substrate. Applied to a secured area, a room or space or floor can be lined so that safe asbestos abatement can be effected.

- 14. A flexible barrier for abating a substance from a predetermined area comprising an area lined with a flexible sheeting thereby to provide a substantially secured area from which the substance can be abated without the release of the substance beyond the secured area, including in combination the flexible sheet and a material having an adhesive surface, the sheet having a first face suitable for receiving the material with an adhesive surface so the material can adhere to the face, the sheet having a series of apertures through the sheet with spaces between the apertures, the apertures being located in at least one substantially straight line and being spaced from an edge of the sheet, the apertures providing sufficient exposure of adhesive material through the apertures such that the sheet can be effectively bonded to a first substrate in the area to be secured located on an opposite face of the first face, and the adhesive material extended across the apertures whereby the adhesive surface partly adheres to the sheet about the spaces and partly to the first substrate, and wherein a second series of apertures through the sheet is located opposite a second substrate in the area to be lined and including adhesive material extended across the apertures and spaces whereby the adhesive surface effectively bonds the sheet to the second substrate, wherein the sheet form a secured area, such that the air pressure of the secured area relative the area beyond the secured area can be changed by pressure differentiating means provided in the sheet thereby to permit for abatement from the secured area, and wherein the first substrate is located adjacent an interface of a ceiling and a wall, and a second substrate is located adjacent an interface of a floor and a wall.
