KDAT, or Kiln Dried After Treatment, pressure treated lumber.

Unlike most pressure treated lumber, with is often is delivered still wet with preservative, KDAT lumber can be painted or stained right away, and it resists warping, cupping, and shrinkage.


Pressure treated lumber is the way to go when you’re building outside because the lumber is protected from wood rot, decay, and pests—like termites. But KDAT, or Kiln Dried After Treatment, lumber offers some additional advantages.

Freshly treated wood has to dry out before it can be finished with paint or stain, so kiln drying eliminates that wait. Plus, evenly drying the boards in a controlled environment minimizes the natural tendency of treated wood to shrink, cup, and warp.
