before installation. After installation, it needs to be stained, painted or sealed immediately, which is an added benefit because you don't have to wait to finish the project. By comparison, freshly treated wood may take weeks or months to dry naturally enough to be finished. KDAT lumber from suppliers such as Yella Wood is easy to han- dle, cut and install, and it weighs less than freshly treated lumber. The wood has a light, natural color for easy staining, painting or sealing, and Yella Wood backs its KDAT lumber with a lifetime limited warranty.
Q:How big of a notch can I cut from a floor joist before it weakens the joist?
A:Floor joists occasionally need to be notched or drilled during construction, but you should take pre- cautions not to weaken the structural strength of the framing member. First rule: Avoid notching a joist along the middle third of its length. However, drilling holes for wiring, etc. along this middle third is acceptable. The holes must be located a minimum of 2 in. from the top and bottom of the joist and from other holes. The maximum hole size is 1/3 the joist’s depth. You can cut a notch at the end of the joist to 1/4 of the joist’s depth (maximum). Along the outer third of a joist, you can cut a notch a maximum of 1/6 the joist depth and 1/3 the joist length without compromising its strength.
