Expert Verdict — Reviewed by the SuperArbor Pro Desk
Hardie fiber cement trim is the go-to choice where wood trim rot, termites or fire exposure are concerns, and primed boards let you field-match any body color. Use stainless or hot-dipped fasteners and follow James Hardie's nailing and clearance guidelines, sealing cut edges as directed. Choose the wider 9-1/4 in. board for wide casing, corner boards or fascia and the narrow size for smaller detail work.
Cut fiber cement with dust-control measures and follow the manufacturer's cutting recommendations and silica dust precautions; wear eye and respiratory protection.
