SEM Black Texture Coating Spray Aerosol 16 oz — Matte Flexible Trim Restorer

SEM 39853 Black Texture Coating Spray is a ready-to-use aerosol that restores and refines textured plastic, vinyl and fiberglass surfaces with a flexible, matte-black finish.

Designed for automotive trim, bumpers, dashboards and molded plastic parts, this 16 oz. aerosol delivers a factory-style textured surface that hides imperfections and provides a paintable, long-lasting layer. The formula combines flexible resins and texture agents so it bonds to a range of substrates and moves with the part, reducing cracking and peeling. Because it sprays on evenly and dries to a low-luster black, it’s commonly used by DIYers and professional shops to refresh interior and exterior components before final topcoats or as a finished look.

How does this help restore older bumpers and plastic trim?

SEM 39853 recreates the original textured appearance on worn or faded plastic and rubberized trim. It hides scuffs and small surface imperfections while forming a resilient layer that resists chips and abrasion.

• Recreates factory texture on bumpers, fascia, and side trim
• Conceals scratches and surface defects without heavy sanding
• Flexible finish reduces flaking on flexible parts
• Quick tack and dry times speed up repair work

What surfaces can I use the spray on and how should I prepare them?

The coating bonds well to clean plastics, fiberglass, and many painted surfaces when prepared correctly. Proper surface prep—cleaning, scuffing and using adhesion promoters when needed—ensures consistent coverage and long-term adhesion.

• Suitable for bumpers, dash trim, vinyl, molded plastics and fiberglass tops
• Clean with a compatible degreaser or SEM prep product
• Lightly scuff glossy areas with scuff pad or fine sandpaper
• Prime or use an adhesion promoter for difficult plastics

How do I apply SEM 39853 for best results?

Shake the can thoroughly and apply several light, even coats from a consistent distance for uniform texture. Allow recommended flash time between coats, then let the coating cure before handling or painting over, following manufacturer instructions for temperature and humidity.

• Shake can vigorously for at least one minute after mixing ball moves freely
• Apply 3–5 light coats from 8–12 inches away for even texture
• Let each coat flash per label directions to avoid runs
• Test on scrap to dial in spray distance and number of coats

Can I paint over this texture coating or use it as a final finish?

Yes—SEM 39853 can serve as a durable final textured finish or a preparatory layer before a topcoat. If you plan to paint over it, scuff the surface lightly and use compatible primers or topcoats to ensure good adhesion and desired sheen.

• Functions as a standalone textured finish for matte black results
• Can be topcoated—scuff and prime as needed for smooth topcoats
• Compatible with many automotive paints when properly prepared
• Reduces need for heavy filler by concealing minor defects

Who is this for? SEM 39853 is suited for auto enthusiasts, restoration shops and DIYers who need a quick, professional-looking way to renew textured plastic and fiberglass parts. It’s particularly useful when you want a flexible, factory-like matte texture that resists cracking on bumpers, dash components, and exterior trim. Choose this 16 oz. aerosol when you need a reliable, easy-to-spray solution to refresh surfaces before final painting or to serve as the finished textured look.
