Composite fences are a relatively new technology. Most composite fences contain wood or grain fibers that absorb water, fade, peal, bubble and separate. This can easily been seen in a faded deck (same technology as a fence) and water stains from sprinklers. It is our opinion that there is currently no composite on the market that has proven itself over the long haul. Many large box stores such as Home Depot now carry a ‘Behr’ stain specifically for faded composites.
