Attach a Kicker Strip

Attach a kicker strip to the bases of the furring strips to push out the boards at a slight angle, helping with positioning and water runoff.

Attach Boards

Drive galvanized siding nails or screws through the top of each length of siding into the studs. You may want to make pilot holes. Apply boards, nailing into every furring strip. Build up rows, overlapping the previous layer each time. Create an overlap of at least a 1-1/2 inches to cover up the fasteners.

Apply Sealant

Use sealant at corners and where boards meet another surface (image 1). A common option for a corner is to use a corner trim piece.

Fiber Cement Tools
Fiber cement siding can be tougher to cut than wood or vinyl siding. Manufacturers have created special tools and blades to help you cut through the material, making it almost as easy as cutting through wood. You can use a special scoring tool, or a carbide-tipped blade in a circular saw (image 2).
