Match of CertainTeed™ 21 Sterling Gray *

Yes. If you are repairing factory-finished CertainTeed 21 Sterling Gray siding after shipping damage, installation damage, field cutting, or service work, order a product option that explicitly says Original Material Match. In this collection, that is the direct touch-up choice because it includes a sheen match.

MyPerfectColor makes a matched paint for the CertainTeed 21 Sterling Gray reference, but only Original Material Match should be used as touch up on the finished surface.

It may match the color reference well, but an older installed surface can still look different from a new match. Sun exposure, chalking, fading, sheen change, texture, and batch variation can all affect how CertainTeed 21 Sterling Gray reads beside the existing siding.

If the area is highly visible or the tolerance is tight, compare against an existing part or a site-specific sample before ordering. That is often safer than relying on the color name alone.

For direct touch up on factory-finished CertainTeed 21 Sterling Gray, choose a product that explicitly says Original Material Match. That is the only option in this collection that is suitable for touch up because it includes a sheen match.

Water-based housepaint, urethane, and epoxy can still be color-matched options, but they do not include a sheen match and should not be treated as direct touch-up products for the finished siding surface. Those options are better for separate parts, accessories, or broader repainting jobs.

A match of CertainTeed 21 Sterling Gray is a siding color reference, so it is useful when you need a replacement board, trim piece, soffit, fascia, shutter, vent, gutter, flashing, or other exterior accessory to blend with the existing material.

For those jobs, use MyPerfectColor matched paint to coordinate the new part with the surrounding CertainTeed finish. If the job is a true touch up on the finished surface, choose Original Material Match instead.

Start by cleaning the surface so dirt, chalk, oil, and other contaminants are removed. If the part allows it, light scuffing can help adhesion, but the correct prep depends on the actual substrate and the existing coating.

Because metal, vinyl, fiber cement, and previously coated parts can behave differently, follow the product directions and test on the actual part when possible. Prime only when the substrate or the application calls for it.

It depends. MyPerfectColor matches the color of the CertainTeed 21 Sterling Gray but may not match the sheen. If you see Custom Sheen as a sheen option, this means we also match the sheen of the material, otherwise you would need to pick the closest sheen available. However, keep in mind that our version of the CertainTeed 21 Sterling Gray is based on matching an official CertainTeed color sample. The color and sheen of your specific CertainTeed 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.

MyPerfectColor has the original CertainTeed color samples. A sample of the CertainTeed 21 Sterling Gray you are looking for is in our library. We are able to make paint and verify that it matches the original.

Please note that if your existing materials are not new and you are trying to touch up, they will have aged and are likely different now than they were when new. MyPerfectColor will be sending paint matching the sample at our facility which has not aged the same as your materials and may also be different due to other factors such as variations in manufacturing processes. If your match is critical, you may consider sending a part of your materials for precise color matching. Learn more about our color matching services.
