Color integrity – a critical part of James Hardie ColorPlus technology – includes color accuracy, color-matching James Hardie siding products, consistency of the paint application, fade resistance and finish longevity.
Color Accuracy
Have you ever taken a gallon of paint back to the store because it didn’t match the rest of your project? How would you feel if one side of your house was a shade darker than the rest? James Hardie’s color variance accuracy standards for our ColorPlus technology finish are three times stricter than what’s acceptable for most “store-bought” paints and more tightly controlled than the automotive industry.
Application Consistency
James Hardie’s proprietary manufacturing process involves applying consistent, multiple coats of paint that was developed especially for our fiber-cement siding. Then, the paint is baked-on in a closely controlled factory environment. Our automated manufacturing process, constant quality monitoring and application of up to 50% more paint – compared to field-applied paint – provides the most consistent paint application at the optimal thickness.

Fade Resistance
Many alternative siding product finishes and paint that’s applied “in the field” can fade quite substantially over time, making the colors dull and difficult to match when repairs or touch-ups are needed later on.
Because our exclusive paint is specifically engineered to withstand the sun’s damaging UV (ultraviolet) rays, the James Hardie ColorPlus technology finish gives you up to 30% better fade resistance.
The ColorPlus Process
James Hardie® siding products with ColorPlus® technology – a unified composition of advanced fiber-cement and baked-on pigment – combine the highest quality raw materials, proprietary manufacturing process and equipment, revolutionary paint technology and innovative color process that gives homeowners a superior siding solution for their homes.
James Hardie – the largest producer of fiber-cement siding in North America – is the only siding manufacturer that controls its product from the initial mixing of the cement to final painting in one facility. To ensure that every board meets James Hardie’s high standards, over 41 quality assurance checks are made throughout the manufacturing process and each batch of siding is also checked at three outside testing facilities to monitor long-term durability.
The James Hardie ColorPlus technology finish also represents a revolutionary breakthrough. The paint used in the process was made especially for James Hardie siding after more than four years in development and over 2,000 formulas tested. The end result is a durable, low-maintenance finish that lasts up to two times longer, has 30% better fade resistance and adheres up to 400% better than any other paint available.
And, James Hardie backs its ColorPlus technology finish with a 15-year warranty that covers both paint and labor.
All of this means that when you choose James Hardie siding products with ColorPlus technology:
- You have the assurance you’ve selected the most durable, low-maintenance, highest-quality siding product possible.
