Troubleshooting
Coating not adhering well
Ensure the surface was properly cleaned and prepared. Remove all grease, oil, and loose rust. Check for incompatible previous coatings.
Uneven finish
Ensure consistent application technique with the brush or roller. Stir the product thoroughly before and during use. Avoid applying in drafts or excessively humid conditions.
Slow drying time
Drying times are dependent on temperature and humidity. Ensure application is within the recommended temperature range (typically 10-30°C). Higher humidity can slow drying.
Bubbling or blistering
This can occur if applied too thickly or if moisture is trapped. Ensure proper ventilation during application and curing. Do not apply in direct sunlight or in very humid conditions.

Setup, Compatibility & Care
Preparation: Ensure surfaces are clean, dry, and free from grease, oil, and rust. For best results, prepare bare metal by shot blasting or abrading. If applying to previously coated surfaces, ensure they are well-prepared and sound. Slight surface rust can be coated over.
Application: This coating can be applied by brush or roller. Ensure application occurs in a well-ventilated area due to its high VOC content. Recommended dry film thickness is 35 µm for optimal protection.
Compatibility: Suitable for bare metal, shot-blasted steel, and well-treated coated surfaces. Can be applied over existing compatible coatings if properly prepared.
Care: After application, allow the coating to cure fully. Avoid exposing treated surfaces to extreme heat until the coating has properly hardened, following the recoating times. Clean tools immediately after use with a suitable solvent. Store in a cool, dry place away from direct sunlight.
