Here are some good reasons to buy an outdoor mat:

• The indoor lobby area is too small for a larger mat.
• The existing indoor lobby mat is large and expensive, and you’d prefer not to replace it so soon from excessive wear.
• You have a revolving door that lacks a scraping application on its floor.
• Dirt and gravel are making their way into the building, causing undue wear on mats and even traveling beyond the mat, damaging tiles or stone floors.

When buying an outdoor mat, firstly identify your intent: to catch gravel before it enters building.
