What materials are good for outdoor porch carpets?

Dyed nylon and polypropylene are materials that are good for outdoor porch carpets. Wood powder, olefin fibers and cotton straw are also popular choices for durable outdoor carpets.

The materials used for outdoor porch carpets are of grass grade, although the carpets are no longer limited to turf patterns. The backing of all carpets handle moisture and water, using materials such as rubber marine backing. The backing is usually coated with an additional compound to improve its seam strength and durability. Natural fibers are less commonly used for outdoor porch carpets, as they tend to retain moisture and attract mildew.
