YellaWood® KDAT

Untitled document

Wood that is KDAT, or Kiln Dried After Treatment, provides many advantages that make it the first choice for homeowners who prefer the natural beauty and character of real wood for their outdoor projects.  

YellaWood® brand products treated with micronized copper preservatives already offer improved painting and staining properties, but freshly treated wood has to dry out before it can be finished. When you build with a wood product that’s dried after treatment, there’s no reason to wait.

What in Tarnation is KDAT?

Following pressure treatment, KDAT products are placed in a large oven, or kiln, where excess moisture is removed and the wood is returned to its original moisture content. This process offers a controlled environment and the wood is dried evenly, helping minimize the natural tendency of freshly treated wood to shrink, cup and warp.
