How to caulk hardie plank lap siding “butt joints” exterior repaints. Caulking hardie plank butt joints pre-2012 involved applying a high-quality exterior caulk to the seams where the ends of the hardie plank siding boards meet. This caulking helps to seal out moisture and prevent water from seeping behind the siding, which can lead to rot and other damage. It is important to use a caulk that is specifically designed for exterior use and is compatible with hardie plank siding. We like to use Sherwin Williams Loxon H1 polyurethane caulking. The caulk should be applied generously and smoothed out to create a tight seal. It is recommended to inspect and re-caulk any joints that show signs of wear or cracking to maintain the integrity of the siding.
