1. Product Overview
SEM COLOR COAT is a specialized flexible coating designed to restore or change the color of most vinyl surfaces, flexible and rigid plastics, carpet, and velour. This product is formulated to be fade-resistant, flexible, and provides a permanent finish. It is not a dye, but a coating that adheres to the surface.

2. Safety Information
DANGER: This product is an EXTREMELY FLAMMABLE AEROSOL. The pressurized container MAY BURST IF HEATED. It is HARMFUL OR FATAL IF SWALLOWED. Vapors are HARMFUL. Causes SERIOUS EYE IRRITATION and SKIN IRRITATION.
Always read and follow all cautions on the back panel of the product container before use. Ensure adequate ventilation during application. Wear appropriate personal protective equipment, including gloves and eye protection.
3. Surface Preparation
Proper surface preparation is critical for optimal adhesion and durability of the COLOR COAT. Follow these steps:
- Clean the Surface: Thoroughly clean the surface to be coated with a suitable cleaner, such as SEM Soap or a comparable automotive-grade cleaner. Remove all dirt, grease, oil, wax, and other contaminants. Rinse thoroughly and allow to dry completely.
- Degrease: For best results on vinyl and plastic, follow cleaning with a degreaser like SEM Plastic & Leather Prep or a similar product. This ensures removal of any remaining residues.
- Scuff (if necessary): For rigid plastics, lightly scuff the surface with a fine abrasive pad (e.g., 320-400 grit) to promote adhesion. Clean again after scuffing.
- Masking: Mask off all areas not intended for coating using automotive-grade masking tape and paper.
- Ventilation: Ensure the work area is well-ventilated to prevent vapor accumulation.
4. Application (Operating Instructions)
Follow these instructions for applying SEM COLOR COAT:
- Shake Can: Shake the aerosol can vigorously for at least one minute after the agitator ball begins to rattle. Continue to shake periodically during application.
- Test Spray: Before applying to the actual surface, test spray on an inconspicuous area or a test panel to ensure color match and spray pattern.
- Application Temperature: Apply at room temperature, ideally between 65°F (18°C) and 80°F (27°C).
- Spray Distance: Hold the can approximately 8-10 inches (20-25 cm) from the surface.
- Apply Thin Coats: Apply COLOR COAT in multiple thin, even coats. Avoid heavy coats, which can lead to runs or an uneven finish.
- Overlap: Overlap each pass by about 50% to ensure complete coverage.
- Recoat Time: Allow 5-10 minutes flash time between coats. Apply additional coats until desired color and coverage are achieved. Typically, 2-3 light coats are sufficient.
- Clear Nozzle: After each use, invert the can and spray for a few seconds to clear the nozzle, preventing clogs.
5. Drying and Curing
Drying times can vary based on temperature, humidity, and film thickness:
- Tack Free: Approximately 10-15 minutes.
- Handleable: Approximately 30 minutes.
- Full Cure: Allow 24 hours for the coating to fully cure before subjecting the surface to heavy use or cleaning.
6. Maintenance
Once cured, surfaces coated with SEM COLOR COAT can be cleaned with mild automotive interior cleaners. Avoid harsh chemicals or abrasive cleaning pads, as these may damage the finish. Regular cleaning will help maintain the appearance and longevity of the coating.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Poor Adhesion | Improper surface cleaning or preparation. | Ensure surface is thoroughly cleaned and degreased. Lightly scuff rigid plastics. |
| Uneven Finish / Runs | Applying coats too heavily or too close to the surface. | Apply multiple thin, even coats from the recommended distance. Allow adequate flash time between coats. |
| Clogging Nozzle | Paint drying in the nozzle. | Invert can and spray briefly after each use to clear the nozzle. |
| Color Mismatch | Incorrect product selection or lighting conditions. | Always test spray on an inconspicuous area first. Ensure proper lighting for color evaluation. |
