Hardie board with ColorPlus® Technology never needs repainting thanks to its baked-on, warranty-backed factory finish, while primed HardiePlank may eventually need paint applied per James Hardie’s guidelines to protect your coverage. Coastal Windows & Exteriors is a James Hardie Elite Preferred contractor and woman-owned exterior remodeling company that has completed 7,000+ installations across 730+ towns in Massachusetts, New Hampshire and Maine since 2011.
What Homeowners Should Know About Hardie Board and Paint
- ColorPlus finish: Hardie board colors available through the ColorPlus Technology line are factory-applied. The finish is engineered to resist fading, cracking, and chipping far longer than field-applied paint in coastal climates.
- Primed board timeline: Standard primed HardiePlank may require periodic repainting over time. James Hardie’s instructions and warranty terms govern how, when, and what products to use.
- Painting cost avoided: The cost to paint the exterior of a house runs up to $12,000. Choosing Hardie board with ColorPlus from the start eliminates that expense entirely over the life of the product.
- Manufacturer guidance matters: If you’re considering repainting primed Hardie board, always consult James Hardie’s current instructions before proceeding. Using non-approved products or techniques can void your warranty and affect the board’s moisture performance.
- Hardie board colors range: The Hardie board colors available through ColorPlus include a broad palette spanning classic whites, warm neutrals, deep grays, and bold accent tones. Hardie ColorPlus colors are consistent across every plank because they’re applied in the factory — not by hand on a ladder.
- Long-term performance: Professionally installed Hardie board lasts 30 or more years. Combined with the ColorPlus finish, homeowners get a siding product that holds its appearance and structural integrity without the maintenance cycle that comes with wood or standard painted fiber cement.
Choosing the Right Hardie Option for Your Home
- Top Pick: Hardie board with ColorPlus Technology for any new installation — it eliminates the repainting cycle entirely and delivers factory-grade color consistency that field painting can’t match. Contact Coastal Windows & Exteriors for a free estimate!
- Before repainting: Always review current James Hardie manufacturer instructions and warranty documentation. What was compliant at installation may have updated guidance today.
- Worth asking: Whether your current Hardie board is primed or ColorPlus before scheduling any paint project. A James Hardie Elite Preferred contractor can assess the product on your home and advise the right path forward.
