RECOMMENDATIONS FOR APPLICATION:
- Mix materials according to designed ratio and use after stirring to uniformity. Be sure to use mixed paint within specified pot life
- Avoid applying on rainy, humid (over 85% humidity), cold (below 10°C) days
- The same product of consistent characteristics (same color and batch) might vary in color when applied using different equipment and methods (dilution ratio). Color check before use is recommended.
- When the product is applied to submerged surfaces or waterproofed concrete areas, peeling may occur. Only apply the product after checking adhesiveness.
- Do not use this product for floor coating.
- In submerged applications, if the product is exposed to water immersion before cured, coating problems might occur, such as chalking, discoloration, blistering, etc.
- When applying to outdoor areas, the next coating should be applied within 3 days. After this period, all surfaces must be sanded before applying the subsequent coat.
- Peeling might occur in enclosed spaces with high humidity. Ensure adequate ventilation during application and drying processes. Proper ventilation is also required when applying solvent-based epoxy primer in enclosed spaces.
RECOMMENDATIONS FOR STORAGE:
- Store in indoor conditions (5°C ~ 35°C), keep away from heat sources and open flames. Keep the product in an upright position and ensure tight lids.
- When disposing of the product, follow disposal guides.
