Setup
Proper preparation ensures optimal performance and safety.
- Surface Preparation: Ensure the surface to be marked is clean, dry, and free of loose debris for best adhesion and visibility.
- Shake Can: Shake the aerosol can vigorously for at least one minute after the mixing ball begins to rattle. Continue shaking occasionally during use.
- Clear Nozzle: Before first use, or if the nozzle is clogged, invert the can and spray for a few seconds onto a scrap surface to clear the valve.
- Attach Applicator (Optional): For extended reach and consistent lines, attach the can to a compatible marking wand (e.g., True Value #542-363) or marking pistol (e.g., True Value #542-326). Ensure the can is securely seated in the applicator.
Operating Instructions
Follow these steps for effective marking.
- Invert Can: This product is designed for inverted use. Hold the can upside down, with the spray tip facing the ground.
- Position: Hold the can approximately 4-10 inches (10-25 cm) from the surface to be marked. Adjust distance for desired line width and intensity.
- Spray: Press the actuator button firmly to begin spraying. Move the can at a steady pace along the desired path to create a consistent line.
- Drying Time: The paint dries to the touch in less than 5 minutes under normal conditions. Allow adequate time before exposing to traffic or elements.
- Layering: For bolder lines or increased visibility, apply multiple thin coats rather than one thick coat. Allow brief drying time between coats.
Maintenance
Proper maintenance extends the life of your product and ensures consistent performance.
- Clear Spray Tip: After each use, invert the can and spray for 2-3 seconds until only clear propellant comes out. This prevents the nozzle from clogging.
- Storage: Store the can upright in a cool, dry, well-ventilated area. Avoid extreme temperatures.
- Inspect Can: Periodically check the can for any signs of damage or leaks. Do not use damaged cans.
Troubleshooting
Common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| No spray or weak spray | Clogged nozzle, insufficient shaking, low can pressure | Shake can vigorously. Invert and spray to clear nozzle. If still no spray, replace can. |
| Uneven or spluttering spray | Inadequate shaking, partially clogged nozzle | Shake can thoroughly. Clear nozzle as described in Maintenance. |
| Paint runs or drips | Spraying too close to surface, applying too thick a coat | Increase distance from surface. Apply lighter, more even coats. |
