Prime cedar clapboard shingles prior to hanging, if they are not already primed. The type of coating used will depend on the type of finish that will be used. Coating protects the clapboard from mildew and discoloration and lengthens the life of the stain finish.
Use only hot-dipped galvanized, stainless steel or aluminum nails with cedar siding. Splitless siding nails are recommended. Hand nailing is the preferred method. Nails should be driven so that they penetrate at least 1 1/4 inches.
Cedar clapboard or bevel siding should be nailed to studs using only one nail per piece at spacing of 24 inches from center.
Start installing the clapboard siding from the the bottom using a furring strip for support of the lower edge.
Overlap the upper edge of the previous row by a minimum of 1 inch. Nail just above the overlap taking care not to nail through the overlap area of the two pieces.
Line up the board placed near top of windows with the window cap whenever possible.
Make certain pieces fit snugly together and that butt joints are made over solid wood.
