Will these work well on Hardie Cement trim? not smooth necessarily, but not as rough as stucco.

Hello - Thank you for asking. These may not work as well as on a completely smooth surface, and if you try it out, we would recommend starting with a light object to test the adherence of the strips. If you have any additional questions or concerns, please connect with our team directly at 1-800-934-7355 Mo-Fri 8am-4:30pm CT.
