Additional Information

The D&Better re-dried boards are for customers wanting the very best. The D&Better grade is usually a clear stock on one face, but does allow for an occasional pin knot or small blemish.

Our D&Better boards are below-ground treated, providing extra protection on your project.

These boards are re-dried after being treated, KDAT – Kiln Dried After Treatment down to a 19% moisture rate.

This step to re-dry the boards after treatment:

  • Helps reduce cupping, twisting and warping by allowing the boards to dry and ultimately shrink in a controlled environment
  • No delay before staining or coating as the wood can be painted or coated immediately without waiting since it is already dry.
  • Greater nail and fastener holding power as the dry treated process allows the boards to hold tighter and stay tighter.
  • Cleaner and lighter in weight since the drying process eliminates the moisture thus reducing the weight of the boards, making them lighter and easier to handle.
  • Environmentally sound as the re-drying assures immediate and maximum preservation fixation within the wood, providing a safer, cleaner and environmentally sound product.
