Outdoor Polypropylene Rug Pros and Cons
An outdoor polypropylene rug can last for years and hold up well to water, sun and soil. The rugs are inexpensive and can be found in designs that used to be reserved for inside the house.
Polypropylene, also known more commonly as olefin, has UV protection so it won't fade, and is made with built–in color rather than dyed so it's colorfast. It's stain-resistant and holds up well under lots of traffic. It's also inexpensive and available in almost any color or pattern, making it a great solution for outdoors.
The material is a petroleum-based, man-made synthetic, so it's not environmentally friendly and can't be considered a "green" material. And the biggest drawback is the limitation with the type of loop in an outdoor polypropylene rug. This type of material is best used in a rug that has tight, looped fibers. If you want a different style or a thicker rug, you'll need to choose a different material. Anything other than tight loops and the rug will look crushed and matted fairly quickly, so you're limited to a certain length of pile with an outdoor polypropylene rug.
