Understanding KDAT

Posted 8 June 2018 8:32 PM by Jase DeBoer

What is it?

Not 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. 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 and work with.
  • The dimensional stability makes it a great choice for outdoor projects.
  • 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 stain it right away as well!

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

  • Decking
  • Railing
  • House foundations
  • Pole barns/storage sheds
  • Boardwalks
  • Flatbed trailers

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

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 understructure. Working with ProWood KDAT treated lumber means your project will be built to last, building code approved and backed by a lifetime limited warranty.
