Step 1: Select Paint Type / Application


A match of Gentek 523 Slate (Vinyl) is a deep, muted slate gray with a very low-chroma character and a faint green cast. With an LRV of 11.85, it reads as a dark color rather than a mid-tone, so the surface feels grounded and subdued instead of bright or reflective.

For factory-finished siding work, Original Material Match is the right choice for direct touch up after shipping damage, installation marks, field cutting, or service work because it includes a sheen match. MyPerfectColor spray paint matched to this reference can also be used on separate siding parts and ancillary items such as trim pieces, vent covers, shutters, brackets, fastener caps, soffit details, and other paintable accessories that need to coordinate with Gentek siding.

Because this color is dark and low-chroma, gloss shift, substrate differences, and surface texture can be more noticeable after application than they would be with a softer mid-tone. A repaired area on aged or weathered installed material may still read differently from nearby factory-finished siding even when the color match is close, and thin coverage over a lighter base can show contrast more easily.

Frequently Asked Questions About Match of Gentek™ 523 Slate (Vinyl) *

Can I use Gentek 523 Slate (Vinyl) for touch up after shipping or installation damage on siding?

Yes, if the job is direct touch up on factory-finished siding, order MyPerfectColor paint matched to Gentek 523 Slate (Vinyl) in an Original Material Match option when available. That is the option type intended for touch up because it includes a sheen match.

Use it for scratches, rub marks, edge damage, field cuts, or small service repairs where you want the repaired area to stay as close as practical to the surrounding factory-finished surface.

Will Gentek 523 Slate (Vinyl) match an older installed siding surface that has weathered?

It is a match to the Gentek 523 Slate (Vinyl) color reference, but an older installed surface can read differently after sun exposure, weathering, chalking, sheen change, texture wear, or batch variation.

If you are touching up beside existing siding, be prepared for the repaired area and the aged surface to look slightly different even when the color reference is correct. That risk is normal with installed exterior materials.

Which MyPerfectColor format should I order for Gentek 523 Slate (Vinyl) touch up?

For direct touch up on factory-finished building materials, choose an Original Material Match product when available because it includes a sheen match. That is the right choice for small touch-up work on siding or similar factory-finished parts.

Other MyPerfectColor formats such as spray paint, paint pens, brush-in-cap bottles, interior/exterior housepaint, urethane, or epoxy can still be color matched, but they are better suited to separate parts, accessories, or broader repainting jobs where a sheen-matched touch up is not the goal.

Can Gentek 523 Slate (Vinyl) be used on siding, trim, or nearby exterior accessories?

Yes. MyPerfectColor can make a matched paint for Gentek 523 Slate (Vinyl) that can be used on siding, trim, soffit, fascia, shutters, gutters, flashings, vents, or replacement parts that need to coordinate with the branded material.

If the item is a direct touch-up on factory-finished siding, use an Original Material Match option when available. If it is a separate part or accessory, choose the format that fits the item and the amount of coverage you need.

How does exterior weathering affect Gentek 523 Slate (Vinyl) on installed siding?

Exterior exposure can change how Gentek 523 Slate (Vinyl) looks over time. Sun, moisture, UV, and general wear can shift the way the installed siding reads compared with the color reference.

For the best result, treat the color as a factory reference and not a guarantee that an aged surface will look identical. If the repair is high visibility, the safest approach is to compare against the actual installed part or a site-specific sample when possible.
