A match of James Hardie Gray Slate is a medium-dark gray with very low chroma and a slight green cast. It reads restrained rather than crisp, with enough depth to hold its shape on exterior parts without looking black or blue.

For direct touch up on factory-finished siding, use MyPerfectColor paint matched to the selected building-material color reference in Original Material Match only, since that option includes a sheen match. This color can also be used on replacement trim boards, soffit or fascia pieces, vent covers, access panels, brackets, and other sprayable siding accessories after shipping damage, installation marks, field cutting, or service work.

Because Gray Slate is fairly dark, the repaired area can show differences in sheen, texture, and substrate more readily than the color itself. A correct color match may still read differently next to aged installed material, chalking, or faded sections, so a replacement part or site-specific sample is often safer when the visual tolerance is tight.

For separate parts, coordinated accessories, or broader repainting where direct touch up is not the goal, other MyPerfectColor formats can be used. The finished appearance will still depend on film build, surface prep, and the underlying material, which can shift how the gray and its slight green undertone appear.

Frequently Asked Questions About Match of James Hardie™ Gray Slate *

Can I use James Hardie Gray Slate 489561 for touch up after shipping damage, installation damage, or field work?

Yes, if the job is direct touch up on a factory-finished surface, choose an Original Material Match product for James Hardie Gray Slate 489561. That option is the right choice when you need a sheen match for scratches, rub marks, cut edges, or small service repairs. Other MyPerfectColor formats can be color-matched, but they should not be treated as the direct touch-up option for factory-finished building materials.

Will James Hardie Gray Slate 489561 match an older installed surface exactly after weathering?

Not always. James Hardie Gray Slate 489561 is the correct color reference, but an installed surface can change with sun exposure, moisture, chalking, texture wear, and sheen change. If you are touching up beside older material, the aged area may read differently even when the color match is right. For the tightest visual result, compare against the actual installed surface or use the most site-specific sample you have.

Which MyPerfectColor format should I order for James Hardie Gray Slate 489561 touch up versus other building-material jobs?

For direct touch up on factory-finished James Hardie Gray Slate 489561, order the option labeled Original Material Match because it includes a sheen match. Water-based housepaint and specialty products such as urethane or epoxy can still be color-matched, but they are better suited to separate parts, accessories, or broader repainting where direct touch-up performance is not the goal.

How should I use James Hardie Gray Slate 489561 on siding, trim, or nearby exterior parts?

Use James Hardie Gray Slate 489561 as the reference when you need a replacement board, trim piece, soffit, fascia, gutter, flashing, vent, or other nearby exterior part to blend with the installed James Hardie siding system. If the job is a small repair on the original factory-finished surface, choose Original Material Match. If it is a separate part or accessory, the color-matched product can be used to coordinate the piece with the surrounding material.

Does exterior exposure affect how James Hardie Gray Slate 489561 will look after installation?

Yes. James Hardie Gray Slate 489561 may read differently on an exposed installed surface because UV, weathering, moisture, and chalking can change the appearance over time. That is why touch up is best planned with the actual condition of the surface in mind, especially on older material. For new or replacement parts, the color reference is usually the most reliable starting point.

However, keep in mind that our version of the James Hardie Gray Slate is based on matching an official James Hardie color sample. The color and sheen of your specific James Hardie parts may vary. If your material is not new and has been exposed to the weather, then it is likely that the color has changed over time. MyPerfectColor samples not been exposed to sunlight and weather. If you need a touch up application, you may need to send us a part so we can create a touch up solution precisely matching the current color and sheen of your specific materials.
