The fingerjointed wood boards are for siding renovations. Smooth, knot-free surfaces on all four sides and precision square edges make the double-primed S4SSE board ideal for a variety of exterior applications, including rake, fascia, corner boards and band boards. The boards are available in width sizes varying from 2 to 12 inches. They are available in 12- and 16-foot lengths. Vacuum coating technology is used to double-prime the boards with 100-percent acrylic latex primer on all six sides.
