Long wear, appearance and low maintenance are among the reasons that some homeowners and builders choose composite materials rather than wooden lumber for decks. In winter, decks made of lumber are more likely than their composite counterparts to be slippery.
Composite decking is made from a combination of recycled wood and plastic. It is a popular alternative to wood because it needs no sanding, does not splinter, holds up well under inclement weather conditions, and is available in a variety of colors and finishes.
Slippery deck surfaces are sometimes caused by algae growth on wood and other organic surfaces. Algae will not grow on composite materials, but pollen, leaves and other yard debris may cause mold or mildew, particularly if trees are near. Wood is more likely to have smooth spots created by wear; such spots may be slippery when wet. Most brands of composite decking have textured finishes to make them slip-resistant. Water and ice accumulation from rain and snow may create slippery conditions on any deck surface.
Light maintenance can prevent slips and falls on composite decks. Regular cleaning with soap and water or a commercial deck cleaner will reduce the risk of a slippery deck surface.
