Care &
Cleaning

With proper installation and care, TimberTech products will provide years of outdoor living pleasure.

Storage & Handling

  • Store TimberTech Products on a flat, level, and dry surface.
  • Do not stack bundles over 8 units high. Stack units with banding and bottom supports aligned.
  • Store TimberTech Products under cover to maintain a clean surface. Always leave factory applied protective wrap in place during storage. If stored outdoors, the product must be covered with non-translucent material.
  • Use care when handling product with a forklift as forks can easily damage the material.
  • If banding is used, use protective corners to prevent indents from the bands.
  • Avoid storing TimberTech products in areas of excessive heat.

Considerations

  • Depending on environmental conditions, TimberTech product colors may appear to weather over time as part of the natural weathering process.
  • Please be aware that excessive heat build on the surface of TimberTech products from external sources such as, but not limited to, fire or reflection of sunlight can potentially lead to damage. For example, sunlight which may be reflected by low-emissivity (Low-E) glass can potentially lead to damage of exterior building products, including TimberTech Deck, Rail, and accessories, due to elevation of surface temperatures which far exceed that of normal exposure of the same materials to direct sunlight. Possible damage by such reflected concentrated light may include melting, sagging, warping, distortion, surface discoloration, increased expansion or contraction, and unusual weathering.
  • The buildup or generation of static electricity is a naturally occurring phenomenon in many plastic based products such as carpeting, upholstery, and clothing, and can occur on alternative decking under certain environmental conditions.
  • Although TimberTech Deck products are cooler to the touch than many other deck board products in similar colors, all decking products will get hot in the sun. Additionally, the darker the decking color, the hotter it will feel.
  • Always remove job site dust, clay, dirt, mud, and other construction products from TimberTech Deck, Rail, and accessory products quickly. Do not allow construction dirt and debris to sit on the TimberTech Deck surface. Do not cut metal objects such as railing on the deck surface, the hot debris from the cut may become embedded in the deck surface resulting in staining and damage.

IMPORTANT Do not allow airborne dust from concrete, landscape blocks, or any masonry product to accumulate on the surface of TimberTech Deck, Rail, and accessories as it may damage the surface of the deck. Do not cut any product on or near TimberTech Decking Products.

Cleaning Terrain, Tropical, and Legacy Collections

Cleaning Products:

  • General Periodic Maintenance Cleaning: A dilution of mild liquid dish soap and water (Dawn Ultra has shown best results)
  • Difficult to remove mud/clay/dirt surface contamination—Chomp Pro Gutter Cleaner or Zep Fast 505
  • Recommended Brush—Quickie Professional Pool and Deck Scrub or medium plastic bristled deck brush
  • Do not use a natural fiber deck brush on capped composites. It can dull the plank surface.

Cleaning Procedure:

  • Clean small, manageable areas keeping area fully saturated until thoroughly rinsed.
  • Saturate the area with the cleaner and allow to soak, DO NOT allow cleaner to dry or evaporate.
  • Scrub with brush/extension handle with moderate downward pressure, with the grain and then against the grain to get into the surface texture.
  • Rinse thoroughly, any remaining cleaner residue will result in a film/haze on the deck surface as it dries.

For Ice Removal:

As with any walking surface, TimberTech decking products may become slippery in winter weather. Take caution when walking on your TimberTech deck in these conditions.

  • Most products containing calcium chloride can be used without damage to the deck/porch surface.
  • These products may leave a white residue which can be cleaned using the cleaning guidelines above.
  • Metal shovels or plastic shovels with a metal leading edge may damage the surface of TimberTech decking and are not recommended for clearing snow from the deck surface.

Cleaning TwinFinish®, ReliaBoard®, and DockSider

Although TimberTech products are low-maintenance, TimberTech recommends periodic cleaning to help maintain the beauty of the product. Follow the cleaner manufacturers’ application instructions and always rinse thoroughly.

  • A power washer can be used when cleaning TimberTech products. The recommended maximum pressure is 1500 psi for TimberTech decks. A fan tip nozzle should be used along with the proper cleaning product. Spray in the direction of the brush/grain pattern to avoid damaging the product. Use caution not to damage the material and always take the proper safety precautions when operating a power washer.

Cleaners that are recommended for periodic cleaning or use with ReliaBoard®, TwinFinish®, and DockSider) are:

  • Wash Safe Spray and Clean Composite Deck Cleaner
  • Resist Mist Composite Deck Cleaner
  • Corte Clean
  • Super Deck Composite Deck Cleaner
  • Thompson’s Water Seal—Oxy Action

*Note that composite deck cleaners such as Corte Clean, Thompson’s Water Seal—Oxy Action, Olympic Deck Cleaner, or other cleaners specified as composite deck cleaners, in powder or liquid form, should not be used with TimberTech Terrain, Tropical, or Legacy Collections. TimberTech Terrain, Tropical, and Legacy Collection deck planks are a capped composite material, the cap of these products are not comprised of a wood/plastic composite.

Dirt, Grime, Tannin, and Mildew Stains
(Timbertech TwinFinish®, ReliaBoard®, and DockSider)

TimberTech wood/plastic composite products are formulated to inhibit mildew growth and minimize staining. Rinse off your TimberTech products periodically with a hose. Even if it appears clean, it is important to prevent build-up of pollen/debris. Mildew stains may occur where moisture, pollens, and/or dirt are present. Mildew needs a food source to grow, which can be grass, pollens, dirt, debris, wood and wood resins.

Maintaining a clean, dry surface is the best method for combating mildew. Ensure that water drains effectively from your deck. For TimberTech TwinFinish, DockSider and ReliaBoard, be sure that gaps exist between planks to allow for drainage.

Cleaners that are recommended for mildew removal and/or heavy cleaning are:

  • Wash Safe Spray and Clean Composite Deck Cleaner
  • Resist Mist Composite Deck Cleaner

Tannin Staining

Like any wood-based product, TimberTech’s wood-plastic composite products (ReliaBoard, TwinFinish, and DockSider) may experience a naturally occurring process called Extractive Bleeding/Tannins. This process may cause a temporary discoloration that will weather away with exposure to flushing rainfall and UV. In most cases the weathering process takes 8-10 weeks but could vary depending on location and specific product application such as a covered porch. Tannins may also be cleaned by utilizing the cleaners referenced for Basic Cleaning Recommendations for ReliaBoard, TwinFinish, and DockSider.
