Troubleshooting
Coating not adhering well
Ensure the surface was thoroughly cleaned and completely dry before application. Remove any grease, oil, or loose particles. For very porous surfaces, consider a test patch or appropriate surface treatment.
Bubbling or blistering after application
This can occur if applied too thickly, if moisture is trapped beneath the coating, or if applied during very cold or humid conditions. Ensure proper ventilation and temperature during application. Allow sufficient drying time.
Slow drying time
Drying times are dependent on temperature, humidity, and coat thickness. Ensure application is within recommended temperature ranges (typically above 5°C/40°F) and with adequate air circulation. Avoid application during heavy fog or rain.
Uneven finish
Ensure consistent application with a brush or roller. Stir the product thoroughly to maintain a uniform consistency. Apply in thin, even coats rather than thick, patchy ones.
