What exactly is KDAT Lumber?

KDAT DeckNot all pressure-treated lumber is created equal. KDAT stands for Kiln Dried After Treatment. KDAT lumber has ALL the same weather-beating durability as traditional treated wood, but with the added bonus of being kiln dried. The lumber used for KDAT is spaced evenly in a kiln and exposed to a specific temperature for removing excess moisture. Through this process, kiln-dried lumber is less prone to shrinking, cupping or warping after being installed.

Here’s what you need to know:
  • KDAT keeps your projects looking better, longer.
  • It’s lighter in weight, making it easier to handle, cut, install, and work with.
  • The dimensional stability makes it a great choice for your outdoor project.
  • KDAT is compatible with aluminum flashings AND exterior fasteners.
What else should you know?

It’s important to seal your KDAT lumber immediately. You’ll want to select a water-repellant sealer with UV stabilizers. This will help reduce the effects of the sun’s rays. You can also stain it right away, which is a great option because you wont have to wait until you're finished with your project!

KDAT lumber should remain completely dry from natural elements both before and during installation.  

You can use KDAT anywhere regular treated lumber may be used.

  • Decking
  • Railing
  • House foundations
  • Pole barns/ storage sheds
  • Boardwalks
  • Flatbed trailers
  • Truck beds 
  • Loading docks 

TIP: With wood alternatives such as composite decking, it’s important to choose lumber for your substructure that won’t fluctuate in size. If you’re investing in an alternative material that lasts a long time, you’ll want the same performance from your wood substructure. 

It is important to choose lumber that you know you can depend on. That’s why homeowners and contractors use KDAT in areas that need the most stabilization, such as your deck’s substructure. Working with ProWood® KDAT treated lumber means your project will be built to last and backed by a lifetime limited warranty.
