KDAT Tongue and Groove Porch Flooring

Untitled document

We love our porches. They’re as much a part of the family as, well, the family dog. The porch is the place where friends are greeted, lazy afternoons are spent, peas are shelled, and grandma weaves the family history like a quilt.

Yes sir, when it comes to our porches, only the best will do. That’s why, for quality porch projects, look to YellaWood® brand tongue and groove porch flooring.  It’s pressure treated for above ground applications and then kiln dried after treatment to minimize shrinkage after installation.  For the best protection against rot, fungal decay and termite attack, you can’t go wrong with YellaWood® brand porch flooring. 

KDAT porch flooring should be primed on all 6 sides (including field cuts) prior to installation.  KDAT flooring installation instructions are available on this site.

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.
