Tough adhesive polythene film for carpets, giving protection from spills and dirt. Unlike many similar products it's reverse wound, which means you can put it down and simply kick it out, instead of needing an applicator. The film is coloured a light yellow, so that walkways for dirty boots can be easily identified. When the job is done, it simply peels from the surface without leaving any sticky residue. Not suitable for use on wool carpets.
