Hardwood Decking

Return to Ipanema Decking Home

One of the most important specifications when classifying decking hardwood is through the National Hardwood Lumber Association or NHLA. More than 100 years ago, rules were created to help grade hardwood used for decking and this form of grading continues nationwide today.

What are decking wood grading specifications?

Through the classification system, decking wood can be graded and categorized for proper usage. The rules allow sellers and buyers of decking hardwood, a common language that enables them to understand the quality of the decking wood. The grade allows sellers to place a value or cost on the wood and helps buyers buy the perfect product for their next project.

Specification for Ipanema Decking

In order to have the best decking wood delivered to you; Ipanema has standards that they require for their decking wood. These standards are for factories, lumber stores, and owners to follow to ensure that the decking wood is the best that it can be for the present and the future.

  • Each piece of Ipanema Decking is to be kiln dried. The moisture levels should average at 15% prior to any milling. This allows the product to be milled without any types of manufacturing defects showing up and enables the product to be uniformed in its dimensions.
  • There cannot be any form of rot or decay present or forming on the decking hardwood, including types of fungal decay. There is a small amount, no more than 10% in width or one foot on edges in length, of sapwood that is allowed on individual pieces of Ipanema decking wood.
  • Each piece of decking must keep their original strength. Structurally, the piece must be sound. Worm holes are permitted in the wood, as long as they don't affect the strength of the product and the number is not excessive. If a worm hole is more than 1/8" in diameter, the piece cannot be used unless it is sanded down and then properly sealed.
  • There may be some forms of defects or surface checking that occurs during the process of drying the decking wood. This is permitted, as long as it is not extensive. However, if too much splitting, checking or twisting is present, the piece is not accepted. The best way to determine if your decking wood is excessive is by sight. If the decking board looks impaired or abnormal, than it is not to be used.
  • During the drying process, stains may be present on your decking wood from the ventilation stickers. These stains are not a defect. However, if they become highly visible on many boards or are showing through the final coating of finish, they should not be used.
  • The factory typically applies a finish prior to the decking wood leaving the store. When this occurs, the finish must be uniform and applied evenly to each piece of Ipanema Decking. It must also be applied to all four sides to ensure optimal protection. When installing, each end of the decking that is cut, should be sealed for protection.
  • Ipanema is a type of decking hardwood. This means that the decking wood must be maintained on a regular basis to ensure durability and appearance. Sealants should be purchased from a store such as San Antonio Wholesale Lumber or other qualified dealers who understand your decking wood. The best time to add your first coating is after the color begins to change color or fade on your decking wood. Contact a sales representative to help you choose the best decking wood.
  • There are substances that you should never apply to your Ipanema decking wood. The following list should never have contact with your decking wood:
  • Chlorides
  • Creosote
  • Preserving salts
  • Pentachlorophenol
