  • Severe Weather with Ecolife minimizes the effects of weathering such as cracking, checking, and splitting with a built-in wood stabilizer.
  • Ecolife is an environmentally advanced preservative, that is a non-metallic, extremely effective wood preservative.
  • The amount of water repellent stabilizer in Ecolife is designed for maximum performance and is standardized by the American Wood Preservation Association.
  • Ecolife treated wood helps protect against UV and rain exposure and is used in building decks, railings, fence pickets, arbors, trellises, joists and beams.
  • Ecolife can be used in direct contact with aluminum products.

  • Micronized Copper Azole (MCA) is specifically treated to protect wood in contact with soil and moisture, a copper-based preservative.

  • We recommend hot-dipped galvanized or stainless steel screws that are building code approved, corrosion-resistant fasteners and connectors suitable
    for use in treated wood.
  • For coastal installations, use code-approved stainless steel.
  • Light sanding will remove or lighten the grade stamp’s appearance.
  • Allow treated wood to dry prior to application – typically around 60 days after installation. Test the wood with a few drops of water to see if the wood is dry enough to readily absorb water, then test a small portion of the deck.
  • We recommend a good quality stain, or exterior wood water sealant product with UV protection. Apply a water repellent sealer at least every two years.
  • Butt boards tightly together during installation as they will shrink slightly in width and thickness as they dry out.
  • Pre-drill holes about 3/4” from the edges of the boards to help prevent splitting.
  • Use screws to improve holding performance.
  • Install fasteners flush to the wood surface. Do not overdrive fastener.
  • For ground contact support posts, install the un-cut ends in the ground.
