TRIMMING CORNERS
When using HardieTrim tabs prebuild outside corners off the wall.
• Attach HardieTrim Corner Tabs to the back side of the trim using eight(8) - 18 ga. 1/2 in. L x 1/4 in. W narrow crown corrosion resistant
staples using a pneumatic stapler. Ensure the HardieTrim Corner Tabs are fastened tight and straight to the trim boards. (figure 25)
• For wood frame construction, attach trim to building using min. 6d siding nails fastened through the HardieTrim Corner Tabs attached to
minimum 7/16 in. OSB *. (figure 26)
• Attach a HardieTrim Corner Tab 1 in. from each ends and every 20 in. O.C.
• TIP: Creating a jig for the work station is recommended to ensure corners are fastened securely and straight. (figure 27)
BAND BOARD
Terminate ends of the Band Board into Trim or Siding or miter cut the edges of the trim at the corners of the building. Place a HardieTrim Flat Tab at the end of each trim board
and one tab every stud at a maximum of 16 in. O.C. The HardieTrim Flat Tabs should be attached to the trim in an alternating pattern to the top and bottom of the band board
(figures 21, 22). Use 16 ga. galvanized 2 in. long finish nails to ensure proper fastening if needed.
