Outdoor carpet is made from polyester, nylon, and polypropylene synthetic fibres which are fade resistant. This means that the carpet will repel dirt and moisture, lowering the risk of mould and mildew. Outdoor carpet is designed to be durable and can withstand prolonged weather events such as rain or intense sunlight without taking damage.

Outdoor carpet is usually installed on a patio or a deck which is open to the weather. An outdoor carpet or rug has a number or practical as well as aesthetic benefits. These include

Considerations

The first thing that you want to look for in an outdoor rug is water resistance. You need to make sure that the rug you are thinking of purchasing is waterproof or at least heavily resistant to water.

Another thing to consider is the type of rug. The majority of outdoor carpets are made from synthetic materials such as polypropylene. However, some natural plant fibres can have the fade resistance necessary to be suitable outdoors. The natural fibre rugs which can be left outdoors are

Sisal
Hemp
Seagrass

However, they are more susceptible to water and the subsequent damage that water exposure inflicts. To avoid your natural fibre rugs developing mould, mildew, or faded colours, you should place them only in outdoor covered areas which will receive less exposure to weather events.

Another strategy for keeping outdoor carpets pristine is to install a rug pad underneath. This will create a barrier between the existing floor that will help with issues of pooling water as well as staining over time. A rug pad also helps with air circulation and can speed along the drying process after a bout of rain.
