To properly install HardiePlank siding, cut the planks to the required size using a power drill or a score, install a lath strip on the house's wall, nail the first plank over it using a nail gun, and attach the subsequent planks by overlapping with the previous ones. Install the siding in a horizontal direction, connect the siding joints on a stud, and use joint flashing beneath all the joints.Continue Reading
Begin installing HardiePlank siding by marking the required measurements on the planks. Clamp the planks on sawhorses, and cut to size using a carbide-bladed power drill or a snap knife and score.
Identify the lowest spot on the houses' side, and install a 1 1/4-inch lath strip along the outer wall's bottom side just over the water table. Position the first siding plank over the lath strip so that it overlaps the latter by 1 1/4 to 1 1/2 inches. Continue installing planks in this manner to the top edge of the wall.
Use 11-gauge roofing nails for the installation. Shoot the nails using a nail gun so that they are positioned 1 1/8 inches from the plank's top edge. Drive the nails into the siding and the wall studs. Install the planks row by row.
If more than one plank is required in a row, position the sides of two planks over a wall stud and flush with each other, and install. To make the joints weather-resistant, position joint flashing beneath them so that each one extends 3 inches on either sides of a joint.
When installing the HardiePlank siding around trims and windows, maintain a gap of at least 1/8 inch to allow for expansion. Use caulk to seal the gaps.Learn more about Building Materials
