A match of Sico 4203-63 Basalt is a low-lightness, muted neutral with a gray-brown base and a faint warm, earthy cast. The low chroma keeps it subdued rather than colorful, so it reads as a quiet dark neutral on finished parts.

MyPerfectColor custom spray paint matched to the selected brand color can be used on vents, switch covers, speaker grilles, brackets, railings, mailbox components, shutters, PVC trim pieces, and other small items where a consistent dark neutral is needed. It is also suited to metal hardware, shelf brackets, fixture parts, and removable accessories that need to coordinate with an existing paint reference without drawing attention to the substrate.

Because this is a darker color, surface prep and sheen control matter. Scratches, texture, and uneven film build can become more visible as the finish deepens, and the final read can shift noticeably between matte, satin, and gloss coatings. On plastics, metal, or previously coated parts, even film build helps the color read consistently across the surface.

Frequently Asked Questions About Match of Sico™ 4203-63 Basalt *

Can I return a custom match of Sico 4203-63 Basalt if I order the wrong sheen or quantity?

No. Custom color matches are made to order, so you should confirm the Sico 4203-63 Basalt reference, the MyPerfectColor product type, the sheen, and the quantity before you buy. If you need MyPerfectColor paint matched to this color for a spray project, make sure the format and finish are correct before checkout because custom-made matches are not returnable or refundable.

How soon can I recoat MyPerfectColor spray paint matched to Sico 4203-63 Basalt?

For MyPerfectColor custom spray paint matched to Sico 4203-63 Basalt, dry-to-touch is usually within minutes, recoating is typically done in 1 to 2 hours, and full curing takes about 2 weeks. Dry-to-touch does not mean the coating is ready for heavy handling, stacking, or reassembly, so plan extra time before putting the part back into service.

Will the finish change how Sico 4203-63 Basalt looks in MyPerfectColor paint?

Yes. A match of Sico 4203-63 Basalt is the color reference, but the finish changes how much light the coating reflects and can change how the color reads on the finished item. MyPerfectColor paint matched to this color can look different in matte, satin, or gloss finishes, so choose the sheen based on the surface you are coating and how closely you need the new part to relate to the existing finish.

If the painted item will sit next to an already coated surface, matching the sheen is often just as important as matching the color reference.

How much MyPerfectColor spray paint matched to Sico 4203-63 Basalt do I need for pipes, vents, or hardware?

A typical can of spray paint covers about 20 square feet with one coat, but the actual amount needed for a match of Sico 4203-63 Basalt depends on the part size, surface texture, hiding power, spray method, and the number of coats required. Small items like brackets, grilles, switch covers, and hardware may take very little paint, while longer runs such as gutters, downspouts, railings, or PVC pipe can require more than one can once you include overspray and second coats.

To avoid running short, estimate the total surface area and allow extra paint if the substrate is rough, porous, or a different color than the finish coat.

Which sheen should I choose for Sico 4203-63 Basalt when ordering MyPerfectColor paint?

Choose the sheen based on the job, not just the color. Sico 4203-63 Basalt identifies the color target, while the finish affects durability, cleanup, and reflectivity. Higher gloss is usually more reflective and easier to wipe down, while lower sheen finishes reduce shine on the coated item.

If you are coating a removable part, fixture, mailbox, vent, or accessory, pick the sheen that best fits the way the item will be used and the finish you need to coordinate with.
