What Type of Problems Occur With TimberTech Decking?

Scratching, fading, mold, heat buildup and becoming slippery when wet are some problems reported for TimberTech decking, as of 2015. Structural integrity risks are less prevalent and are mitigated by following installation recommendations.

TimberTech decking is a composite material made of wood particles and high-density polyethylene, with added compounds to resist rot, mold and scratching. Scratching is an issue with all deck materials. TimberTech recommends using leg caps on deck furniture and grill mats to minimize this risk, avoiding vinyl or rubber. It also suggests limiting power washers to 1500 pounds per square inch, using a fan tip and directing the spray parallel to any pattern. Choosing the best approach for removing scratches depends on the particular decking line. A wire brush, Minwax stain and a soldering iron are some methods based on model and damage severity.

Fading is caused by weathering and is natural for all deck products. While early versions of TimberTech decking faded rapidly, the addition of a bonded protector eliminates unusual fading. Paints or refinishers revitalize a faded surface but require reapplication, offsetting a benefit of composite materials. Any finishing product requires precleaning and applying according to the manufacturer’s instructions.

Stains result from mold, dirt, grease or reaction with rubber or vinyl matting. TimberTech recommends the regular use of environmentally friendly deck-cleaning products. Performing the process in the early morning or late evening prevents evaporation and powdery residues.
