Zipped Doorway Dust Sheet Protector Kit - 

This product is a simple solution to a problem often encountered when carrying out building, renovation, sanding, or any work that creates dust: how to stop the dust getting into other rooms. It comprises a 2.1m x 1.2m (7' x 4') sheet of durable polythene that fits standard doorways plus a self-adhesive zip that can be readily trimmed to size as required. The zip is applied down the middle of the sheet and then a sharp knife is run down the middle of the zip to slit the sheet. The sheet then attaches to the door frame with masking tape or other tape (not included), forming a dustproof and waterproof barrier and giving easy two-way access to and from the area whilst works are under way.
