SEM Color Coat vinyl & plastic — Medium Gray 12 oz, flexible fade-resistant finish for interiors & trim

SEM 15393 Medium Gray Color Coat is a flexible, permanent coating designed to restore or change the color of most vinyl, plastics, carpet and velour without acting as a dye.

This specially formulated elastomeric finish bonds to flexible and rigid vinyls, various plastics, and textile surfaces to provide a fade-resistant, durable color update. Unlike dyes that soak into fibers, this product lays down a flexible film that resists flaking and stays uniform under normal use. It’s available in a 12 oz. size and is intended for professional detailers, restoration specialists, and do-it-yourselfers who need a reliable, long-lasting color solution for automotive interiors, trim pieces, and household items.

How does SEM Color Coat adhere to different surfaces?

SEM Color Coat uses a formulation that promotes mechanical and chemical adhesion to prepared vinyl, plastics, and textile backings. Proper cleaning and scuffing of the surface are essential to maximize bond strength and longevity.

• Works on flexible and rigid vinyls, many plastics, carpet and velour.
• Requires cleaning with a suitable surface prep and light abrasion for best adhesion.
• Forms a continuous elastomeric film that moves with flexible materials.

What steps should I follow for a smooth, long-lasting finish?

Surface preparation, application technique, and curing conditions all affect the final result. Clean thoroughly, remove contaminants and loose finish, then apply thin, even coats to build color while avoiding runs.

• Clean surface with a compatible cleaner and remove any oils or residues.
• Lightly scuff or abrade glossy areas to improve mechanical grip.
• Apply multiple light coats, allowing flash time between passes for even coverage.

Where is SEM Color Coat best used and what should I avoid?

This coating excels on interior automotive trim, instrument panels, door panels, seat edges, and other vinyl or plastic parts as well as certain textile applications. Avoid use on high-temperature engine components or surfaces that contact skin frequently unless manufacturer guidance permits it.

• Ideal for interior trims, molded plastics, and upholstery accents.
• Not intended as a substitute for structural or high-heat coatings.
• Test in an inconspicuous area for compatibility with specific materials.

How durable and fade-resistant is the Medium Gray finish?

The product is formulated to be fade-resistant and flexible, helping it maintain appearance under regular use and exposure. Longevity depends on UV exposure, abrasion, and maintenance—routine care will extend the lifespan of the finish.

• Elastomeric film resists cracking and maintains flexibility on moving parts.
• Designed for color stability under typical interior conditions.
