Back-Priming Fiber-Cement Siding
Q: We ordered preprimed HardiePlank lap siding to finish a project, but when it was delivered, we discovered that the backs were left unprimed. Normally, we back-prime wood clapboards, but I'm not sure this step is needed with fiber-cement siding, and the manufacturer's Web site is mute on the subject. Is back-priming necessary?
