What is KDAT?

Kiln Dried After Treatment (KDAT) is a process that removes excess moisture from lumber, minimizing the natural characteristics of wood to shrink, cup, and warp.  This process will minimize the shrinkage and increase the stability of the lumber.  KDAT also improves the holding power of nails and screws.

KDAT is a great product to DECK OUT YOUR DOCK!

KDAT is a great product for the following projects:

  • Outdoor decks
  • Fences
  • Pergolas
  • Bridges
  • Docks

What to Expect With KDAT?

Wood is a porous material, which makes it ideal for the pressure treating process. Because it is porous, wood has a natural tendency to warp, cup, twist, crack, check, shrink and swell as it is exposed to wetting and drying cycles. The pressure-treating process fully saturates wood with preservatives and water. While the preservative is left in the wood for protection, the water is released as the wood naturally dries, bringing out these natural characteristics. Kiln Dried After Treatment, “KDAT” is a process that removes this excess moisture from wood introduced by the treating process. Kiln drying after treatment helps to improve the performance and stability of pressure-treated wood.

KDAT is Still Pressure Treated Wood

While the KDAT process helps to improve the stability of pressure treated wood, it does not make it impervious to wood’s natural characteristics. 
This is especially true if it is exposed to wet ting and dry cycles prior to installation.
