Outdoor entrance mats used by schools in a surface application should possess certain attributes. All exterior floor mats for schools should be UV stable, dry quickly, provide a nonslip walk surface and should ideally provide a scraping function to remove sand, salt and grit from shoes. Outdoor walk off matting should also present a low profile and have beveled edges to prevent a tripping hazard. If high winds are a possibility, the entry mats should either be large enough to stay in place or they should be glued down to prevent mat movement. Most carpet mats used outside should have solution dyed polypropylene fibers to dry quickly and to make cleaning a breeze.
